But we can geek out even more. The 500 Auto Max, according to data provided by Big Horn Armory, pushed a 400-grain bullet to a 2,275 fps muzzle velocity out of an 18-inch barrel in the BHA AR500. That outperforms well-known thumpers like the .45-70 and .450 Marlin with comparable bullet weights. <\/p>\n","post_title":"Big Horn Armory's AR500 Starter Kit Brings Big-Bore Hunting Power","post_excerpt":"","post_status":"publish","comment_status":"open","ping_status":"open","post_password":"","post_name":"bha-ar500-starter-kit","to_ping":"","pinged":"","post_modified":"2023-05-31 10:13:34","post_modified_gmt":"2023-05-31 10:13:34","post_content_filtered":"","post_parent":0,"guid":"https:\/\/www.athlonoutdoors.com\/2022\/04\/21\/bha-ar500-starter-kit\/","menu_order":0,"post_type":"post","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":157150,"post_author":"284","post_date":"2013-01-01 13:51:54","post_date_gmt":"2013-01-01 19:51:54","post_content":"It's not a big .50 BMG, but the Weatherby Mark V TRR and their .338-378 load can blow the socks off anything else at ultra-long range<\/em>\n\nRifle shooting seems to go in phases in America, and right now it\u2019s long-range shooting\u2019s time to shine. American shooters are fascinated with the concept of reaching out and smacking targets so far away that they clang with a different accent.\n\nIt wasn\u2019t so long ago that we thought 500 yards was \u201clong range.\u201d Then 1,000 yards became the new normal. Now it starts getting interesting for a lot of shooters at 1,500 yards.\n\nIn recent years the .338 Lapua has emerged as the premier long-range sniper rifle cartridge. That\u2019s because for shooting at ultra-long range, 1,000 yards and beyond, many believe it\u2019s the cartridge that best achieves balance.\n\n\"d15236_phatch\"<\/a>\nWeatherby Mark V Sub-MOA Threat Response rifle features an oversize bolt handle for ease of operation<\/em>\n\nThe .50 BMG is not much fun to shoot for extended periods of time with all the blast and recoil. I have seen the muzzle brake on a fifty clear a shooting bench, even send a chronograph flying. Once I witnessed ammo boxes being blown off the bench along with a bag of potato chips turned into airborne confetti. That kind of blast level can wear on a shooter after multiple shots.\n\nOn the other end of the sniper cartridge spectrum is the .308 Winchester, which is running out of steam at 1,000 yards and is completely outclassed at 1,500 yards. The Lapua splits the difference and has proven that a big, heavy, high B.C. bullet is the key. Most .338 Lapua rifles weigh less than 20 pounds so they are easily transported. With that weight class and a good muzzle brake, the .338 Lapua is easy on the shooter with mild recoil and muzzle blast.\n\nThe .338 Lapua owes its success to two things: first it\u2019s a good cartridge, but perhaps even more important, it\u2019s had great marketing. Of course it doesn\u2019t hurt that the .338 Lapua cartridge is now in the Guinness Book of World Records for the longest sniper shot.\n\nA British sniper named Craig Harrison fired three shots with his Accuracy International .338 Lapua rifle during an altercation in the sandbox. The first round hit a bad guy running a machine gun and killed him. Another insurgent stepped up to the machine gun and a second bullet killed him. The third shot took out the machine gun. The distance was measured by GPS at 2,707 yards or 1.54 miles. That\u2019s long enough that, according to my ballistic program, it took the bullets more than five seconds to get there.\n\nMilitary Roots<\/strong>\n\nThe main reason that the .338 Lapua has become so popular is because the military is using it for long-range work. Selection by the military will all but guarantee the popularity of any cartridge. Note the four most popular sniper rifle cartridges, the .308, .300 Win, .338 Lapua and the .50 BMG. They are all popular because the military uses them. But other than the .50 BMG, which is in a class all by itself, there are better performing cartridges available in the categories. They fail to achieve the degree of success, not because of any technical reason, but because of the military connection. But civilians are not bound by military selection and we can pick the cartridge that works best, not the one that some politicized General says we must use.\n\nThe .338 Lapua was developed with the 250-grain bullet in mind. Lately there is a move to 300-grain bullets, but at least for now the 250-grain is still the cartridge standard. Federal\u2019s most popular .338 Lapua load uses a 250-grain MatchKing bullet with a peak B.C. of 0.606 and a M.V. of 2,950 fps. While that\u2019s a respectable muzzle velocity, there is at least one commercial cartridge capable of driving the same bullet even faster, the .338-378 Weatherby.\n\nWeatherby\u2019s .338<\/strong>\n\n\"d14080_phatch\"<\/a>\nThe .338-378 uses the .378 Weatherby case necked down to take a .338 bullet, resulting in a sizeable cartridge with a 20-percent increase in case capacity<\/em>\n\nLike all the Weatherby rifle cartridges, the .338-378 was developed for hunting. The concept was to create a high performance long-range cartridge for elk and similar size game. But, long range shooting is long range shooting regardless if the target is an elk or a steel gong. The only requirement is simply that the rifle delivers a bullet to the target. If there is a cartridge that gets it there faster and hits the target harder, then where is the downside?\n\nThe .338-378 Weatherby cartridge uses the .378 Weatherby case, necked down to take a .338 bullet. That means it is a whopping big cartridge case. The .338-378 Weatherby case holds 137 grains of water compared to the .338 Lapua, which holds 114 grains of water. That\u2019s about a 20 percent increase in case capacity. More capacity means more propellant and more propellant means higher muzzle velocity. While the laws of diminishing returns start to apply with this big case, it still can push the same bullet substantially faster than the Lapua. That means the bullet gets to the target faster, retains more energy and has a flatter trajectory curve.\n\nWeatherby lists the muzzle velocity of their 250-grain Nosler Partition load at 3,060 fps. Hodgdon\u2019s online handloading data lists the .338-378 Weatherby with a 250-grain bullet with a statistically identical muzzle velocity of 3,072 fps. That\u2019s faster than anything else that is pushing the same diameter and weight bullet.\n\nUsing a 250-yard zero, by the time the bullet is at 1,500 yards that little bit of extra velocity has the point of impact for the .338-378 at 73.19 inches higher than the .338 Lapua. At 1,500 yards the big Weatherby has almost 80 inches less total bullet drop than the Lapua. Another big issue at ultra-long range, one that is often not considered by most shooters, is retained energy. All cartridges are dropping to low energy levels at 1,500 yards. For example, the .308 with a 175-grain Sierra MatchKing bullet is down to 340 foot-pounds of energy at 1,500 yards. That\u2019s about the same as a 9mm pistol at the muzzle.\n\n\"d14168_phatch\"<\/a>\n\nThe .338 Lapua has 763 foot-pounds of retained energy at 1,500 yards while the .338-378 has 831 foot-pounds. That\u2019s nearly a 10% increase and at that distance every foot-pound counts.\n\nThere is no question that assuming equal accuracy, the .338-378 Weatherby deserves consideration by the long-range shooting crowd and that it can surpass the performance of their current darling, the .338 Lapua.\n\nThe problem was that until now you could only find the .338-378 in a hunting style rifle. If you wanted it in a tactical, long-range configuration you had to have it custom built. But that\u2019s changed.\n\nThreat Response .338-378<\/strong>\n\nWeatherby has entered into the long-range tactical rifle market recently with their Range Certified, Mark V Threat Response Rifle. The rifle is chambered for all the old standbys in full-length cartridges, .300 Winchester, .300 Weatherby and .30-378 Weatherby. That last cartridge can do for the 30-calibers what the .338-378 does for the 33s\u2014push any given bullet weight out the muzzle faster than any other 30-caliber cartridge. The rifle is, of course, offered in .338-378 Weatherby and, new for 2012, the .338 Lapua.\n\nThe rifle features a Krieger barrel with cut rifling. It\u2019s a #3 contour 26-inch fluted barrel with a big muzzle brake fitted on the end that has five slots on each side. The twist rate is 1:10, so the rifle can use bullets weighing 300 grains. The barrel is fully free-floated clear back to the action.\n\nThe camo stock has a flat-bottom forend to sit well in sandbags, as well as a metal slot for a swivel stud to attach a bi-pod. This slot allows 9 inches of adjustment for the stud placement. The stock has an adjustable comb that is locked securely in place with two Allen head screws. The stock is adjustable for length of pull with removable spacers from 13.25 inches to 14.75 inches. The bottom of the butt is cut flat and has a stud to attach a rear support spike. The pistol grip is large and drops almost straight down to position the hand behind the trigger.\n\nThe bolt has an extended oversize knob. The push feed bolt has a spring-loaded plunger in the face for an ejector and a pivoting, spring loaded extractor fitted to the bolt.\n\nThe bolt is classic Weatherby Mark V with nine locking lugs. This means a shorter 54-degree rotation to open the bolt, which makes it faster to operate. The Mark V uses a full-size, fluted bolt body running inside the tubular action. There is no binding and it runs smooth. The bolt head is actually smaller than the bolt body. According to a Weatherby representative, that is why they do not use a removable box magazine.\n\n\"d15244_phatch\"<\/a>\n\nNot having a removable box magazine is one of the few criticisms I have of the rifle. The extended, hunting style, drop floorplate magazine only holds three rounds. It\u2019s also a bit slow to reload as the loaded cartridges are longer than the loading port, so they must be put in point first and then moved back to position as they are pushed down into the magazine.\n\nThere is a large two-position safety on the right side of the action. It rotates forward for fire and back for safe. The trigger on my sample breaks cleanly at 3 pounds, 3 ounces.\n\nI ordered a rail style scope mount from Evolution Gun Works, Inc. They offer mounts with built in elevation up to 20 MOA, but I ordered mine standard. I fitted the gun with a Swarovski 6-24x50 scope (swarovskioptik.us). The clear optics and reliable repeatability of the adjustments make this a good choice for this rifle.\n\n\"d15246_phatch\"<\/a>\nThe Weatherby .338-378 was developed to create a high-performance cartridge for hunting monster bull elk and similar big-game species at long range<\/em>\n\nFeeding The Beast<\/strong>\n\nThe other downside of this cartridge for long-range shooting is that ammo is only available from Weatherby and so far they only make hunting style ammo. It\u2019s available in three configurations; a 200-grain Nosler Accubond bullet at 3,380 fps muzzle velocity. This bullet has a B. C. of .414, which is not horrible, so it can work pretty well for long-range work. The next load has a 225-grain Barnes TSX bullet with a muzzle velocity of 3,180 and a B.C. of .482. The final load is a 250-grain Nosler Partition bullet at 3,060 fps with a B.C. of .482. I was only able to test the first two in my rifle as the Partition load was out of stock. The accuracy for five-shot groups was a little disappointing, but I suspect it\u2019s ammo more than the rifle. To make this rifle perform for long-range work, both in accuracy and in exterior ballistics, is going to require handloading. But, then again, anybody serious about precision shooting is likely going to handload. My guess is the 250-grain and 300-grain bullets that are offered will really make this gun step up and shine. The 250-grain can be driven to 3,072 fps according to Hodgdon. The 300-grain Sierra will exit at 2,818 and is an even better performer at ultra-long range than the 250-grain, due to the ultra-high ballistic coefficient.\n\nIf you want the biggest, baddest, 33-caliber long-range commercial cartridge on the planet and you don\u2019t mind working a bit to build the ammo, check out this new Weatherby TRR. It can blow the socks off anything else at ultra-long range.

The 500 Auto Max comprises a rimless 500 S&W. Magnum. Available factory ammo features bullet weights ranging from 350 to 600 grains. Handloaders get to work from 275 all the way up to a massive 700 grains. So this means you can really dial in on working up the right load to the particular application. Bullets also come in hard cast, jacketed hollow points and even monolithic solids. So there's a lot a good gun geek can really hone in on here in terms of performance. <\/p>\n\n\n\n

The 500 Auto Max comprises a rimless 500 S&W. Magnum. Available factory ammo features bullet weights ranging from 350 to 600 grains. Handloaders get to work from 275 all the way up to a massive 700 grains. So this means you can really dial in on working up the right load to the particular application. Bullets also come in hard cast, jacketed hollow points and even monolithic solids. So there's a lot a good gun geek can really hone in on here in terms of performance. <\/p>\n\n\n\n

\"Fired<\/figure>\n\n\n\n

But we can geek out even more. The 500 Auto Max, according to data provided by Big Horn Armory, pushed a 400-grain bullet to a 2,275 fps muzzle velocity out of an 18-inch barrel in the BHA AR500. That outperforms well-known thumpers like the .45-70 and .450 Marlin with comparable bullet weights. <\/p>\n","post_title":"Big Horn Armory's AR500 Starter Kit Brings Big-Bore Hunting Power","post_excerpt":"","post_status":"publish","comment_status":"open","ping_status":"open","post_password":"","post_name":"bha-ar500-starter-kit","to_ping":"","pinged":"","post_modified":"2023-05-31 10:13:34","post_modified_gmt":"2023-05-31 10:13:34","post_content_filtered":"","post_parent":0,"guid":"https:\/\/www.athlonoutdoors.com\/2022\/04\/21\/bha-ar500-starter-kit\/","menu_order":0,"post_type":"post","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":157150,"post_author":"284","post_date":"2013-01-01 13:51:54","post_date_gmt":"2013-01-01 19:51:54","post_content":"It's not a big .50 BMG, but the Weatherby Mark V TRR and their .338-378 load can blow the socks off anything else at ultra-long range<\/em>\n\nRifle shooting seems to go in phases in America, and right now it\u2019s long-range shooting\u2019s time to shine. American shooters are fascinated with the concept of reaching out and smacking targets so far away that they clang with a different accent.\n\nIt wasn\u2019t so long ago that we thought 500 yards was \u201clong range.\u201d Then 1,000 yards became the new normal. Now it starts getting interesting for a lot of shooters at 1,500 yards.\n\nIn recent years the .338 Lapua has emerged as the premier long-range sniper rifle cartridge. That\u2019s because for shooting at ultra-long range, 1,000 yards and beyond, many believe it\u2019s the cartridge that best achieves balance.\n\n\"d15236_phatch\"<\/a>\nWeatherby Mark V Sub-MOA Threat Response rifle features an oversize bolt handle for ease of operation<\/em>\n\nThe .50 BMG is not much fun to shoot for extended periods of time with all the blast and recoil. I have seen the muzzle brake on a fifty clear a shooting bench, even send a chronograph flying. Once I witnessed ammo boxes being blown off the bench along with a bag of potato chips turned into airborne confetti. That kind of blast level can wear on a shooter after multiple shots.\n\nOn the other end of the sniper cartridge spectrum is the .308 Winchester, which is running out of steam at 1,000 yards and is completely outclassed at 1,500 yards. The Lapua splits the difference and has proven that a big, heavy, high B.C. bullet is the key. Most .338 Lapua rifles weigh less than 20 pounds so they are easily transported. With that weight class and a good muzzle brake, the .338 Lapua is easy on the shooter with mild recoil and muzzle blast.\n\nThe .338 Lapua owes its success to two things: first it\u2019s a good cartridge, but perhaps even more important, it\u2019s had great marketing. Of course it doesn\u2019t hurt that the .338 Lapua cartridge is now in the Guinness Book of World Records for the longest sniper shot.\n\nA British sniper named Craig Harrison fired three shots with his Accuracy International .338 Lapua rifle during an altercation in the sandbox. The first round hit a bad guy running a machine gun and killed him. Another insurgent stepped up to the machine gun and a second bullet killed him. The third shot took out the machine gun. The distance was measured by GPS at 2,707 yards or 1.54 miles. That\u2019s long enough that, according to my ballistic program, it took the bullets more than five seconds to get there.\n\nMilitary Roots<\/strong>\n\nThe main reason that the .338 Lapua has become so popular is because the military is using it for long-range work. Selection by the military will all but guarantee the popularity of any cartridge. Note the four most popular sniper rifle cartridges, the .308, .300 Win, .338 Lapua and the .50 BMG. They are all popular because the military uses them. But other than the .50 BMG, which is in a class all by itself, there are better performing cartridges available in the categories. They fail to achieve the degree of success, not because of any technical reason, but because of the military connection. But civilians are not bound by military selection and we can pick the cartridge that works best, not the one that some politicized General says we must use.\n\nThe .338 Lapua was developed with the 250-grain bullet in mind. Lately there is a move to 300-grain bullets, but at least for now the 250-grain is still the cartridge standard. Federal\u2019s most popular .338 Lapua load uses a 250-grain MatchKing bullet with a peak B.C. of 0.606 and a M.V. of 2,950 fps. While that\u2019s a respectable muzzle velocity, there is at least one commercial cartridge capable of driving the same bullet even faster, the .338-378 Weatherby.\n\nWeatherby\u2019s .338<\/strong>\n\n\"d14080_phatch\"<\/a>\nThe .338-378 uses the .378 Weatherby case necked down to take a .338 bullet, resulting in a sizeable cartridge with a 20-percent increase in case capacity<\/em>\n\nLike all the Weatherby rifle cartridges, the .338-378 was developed for hunting. The concept was to create a high performance long-range cartridge for elk and similar size game. But, long range shooting is long range shooting regardless if the target is an elk or a steel gong. The only requirement is simply that the rifle delivers a bullet to the target. If there is a cartridge that gets it there faster and hits the target harder, then where is the downside?\n\nThe .338-378 Weatherby cartridge uses the .378 Weatherby case, necked down to take a .338 bullet. That means it is a whopping big cartridge case. The .338-378 Weatherby case holds 137 grains of water compared to the .338 Lapua, which holds 114 grains of water. That\u2019s about a 20 percent increase in case capacity. More capacity means more propellant and more propellant means higher muzzle velocity. While the laws of diminishing returns start to apply with this big case, it still can push the same bullet substantially faster than the Lapua. That means the bullet gets to the target faster, retains more energy and has a flatter trajectory curve.\n\nWeatherby lists the muzzle velocity of their 250-grain Nosler Partition load at 3,060 fps. Hodgdon\u2019s online handloading data lists the .338-378 Weatherby with a 250-grain bullet with a statistically identical muzzle velocity of 3,072 fps. That\u2019s faster than anything else that is pushing the same diameter and weight bullet.\n\nUsing a 250-yard zero, by the time the bullet is at 1,500 yards that little bit of extra velocity has the point of impact for the .338-378 at 73.19 inches higher than the .338 Lapua. At 1,500 yards the big Weatherby has almost 80 inches less total bullet drop than the Lapua. Another big issue at ultra-long range, one that is often not considered by most shooters, is retained energy. All cartridges are dropping to low energy levels at 1,500 yards. For example, the .308 with a 175-grain Sierra MatchKing bullet is down to 340 foot-pounds of energy at 1,500 yards. That\u2019s about the same as a 9mm pistol at the muzzle.\n\n\"d14168_phatch\"<\/a>\n\nThe .338 Lapua has 763 foot-pounds of retained energy at 1,500 yards while the .338-378 has 831 foot-pounds. That\u2019s nearly a 10% increase and at that distance every foot-pound counts.\n\nThere is no question that assuming equal accuracy, the .338-378 Weatherby deserves consideration by the long-range shooting crowd and that it can surpass the performance of their current darling, the .338 Lapua.\n\nThe problem was that until now you could only find the .338-378 in a hunting style rifle. If you wanted it in a tactical, long-range configuration you had to have it custom built. But that\u2019s changed.\n\nThreat Response .338-378<\/strong>\n\nWeatherby has entered into the long-range tactical rifle market recently with their Range Certified, Mark V Threat Response Rifle. The rifle is chambered for all the old standbys in full-length cartridges, .300 Winchester, .300 Weatherby and .30-378 Weatherby. That last cartridge can do for the 30-calibers what the .338-378 does for the 33s\u2014push any given bullet weight out the muzzle faster than any other 30-caliber cartridge. The rifle is, of course, offered in .338-378 Weatherby and, new for 2012, the .338 Lapua.\n\nThe rifle features a Krieger barrel with cut rifling. It\u2019s a #3 contour 26-inch fluted barrel with a big muzzle brake fitted on the end that has five slots on each side. The twist rate is 1:10, so the rifle can use bullets weighing 300 grains. The barrel is fully free-floated clear back to the action.\n\nThe camo stock has a flat-bottom forend to sit well in sandbags, as well as a metal slot for a swivel stud to attach a bi-pod. This slot allows 9 inches of adjustment for the stud placement. The stock has an adjustable comb that is locked securely in place with two Allen head screws. The stock is adjustable for length of pull with removable spacers from 13.25 inches to 14.75 inches. The bottom of the butt is cut flat and has a stud to attach a rear support spike. The pistol grip is large and drops almost straight down to position the hand behind the trigger.\n\nThe bolt has an extended oversize knob. The push feed bolt has a spring-loaded plunger in the face for an ejector and a pivoting, spring loaded extractor fitted to the bolt.\n\nThe bolt is classic Weatherby Mark V with nine locking lugs. This means a shorter 54-degree rotation to open the bolt, which makes it faster to operate. The Mark V uses a full-size, fluted bolt body running inside the tubular action. There is no binding and it runs smooth. The bolt head is actually smaller than the bolt body. According to a Weatherby representative, that is why they do not use a removable box magazine.\n\n\"d15244_phatch\"<\/a>\n\nNot having a removable box magazine is one of the few criticisms I have of the rifle. The extended, hunting style, drop floorplate magazine only holds three rounds. It\u2019s also a bit slow to reload as the loaded cartridges are longer than the loading port, so they must be put in point first and then moved back to position as they are pushed down into the magazine.\n\nThere is a large two-position safety on the right side of the action. It rotates forward for fire and back for safe. The trigger on my sample breaks cleanly at 3 pounds, 3 ounces.\n\nI ordered a rail style scope mount from Evolution Gun Works, Inc. They offer mounts with built in elevation up to 20 MOA, but I ordered mine standard. I fitted the gun with a Swarovski 6-24x50 scope (swarovskioptik.us). The clear optics and reliable repeatability of the adjustments make this a good choice for this rifle.\n\n\"d15246_phatch\"<\/a>\nThe Weatherby .338-378 was developed to create a high-performance cartridge for hunting monster bull elk and similar big-game species at long range<\/em>\n\nFeeding The Beast<\/strong>\n\nThe other downside of this cartridge for long-range shooting is that ammo is only available from Weatherby and so far they only make hunting style ammo. It\u2019s available in three configurations; a 200-grain Nosler Accubond bullet at 3,380 fps muzzle velocity. This bullet has a B. C. of .414, which is not horrible, so it can work pretty well for long-range work. The next load has a 225-grain Barnes TSX bullet with a muzzle velocity of 3,180 and a B.C. of .482. The final load is a 250-grain Nosler Partition bullet at 3,060 fps with a B.C. of .482. I was only able to test the first two in my rifle as the Partition load was out of stock. The accuracy for five-shot groups was a little disappointing, but I suspect it\u2019s ammo more than the rifle. To make this rifle perform for long-range work, both in accuracy and in exterior ballistics, is going to require handloading. But, then again, anybody serious about precision shooting is likely going to handload. My guess is the 250-grain and 300-grain bullets that are offered will really make this gun step up and shine. The 250-grain can be driven to 3,072 fps according to Hodgdon. The 300-grain Sierra will exit at 2,818 and is an even better performer at ultra-long range than the 250-grain, due to the ultra-high ballistic coefficient.\n\nIf you want the biggest, baddest, 33-caliber long-range commercial cartridge on the planet and you don\u2019t mind working a bit to build the ammo, check out this new Weatherby TRR. It can blow the socks off anything else at ultra-long range.

Better still, the package includes the BHA AR500 rifle<\/a>. Chambered in 500 Auto Max, this modern sporting rifle brings serious thump. For AR users, within that familiar manual of arms, shooters get uncommon knockdown power in a short- to medium-range cartridge. Big Horn Armory even offers a braced-pistol variant if you seek a compact field gun. <\/p>\n\n\n\n

Big Horn Armory cautioned this one will only be available for a limited time. For more info, call 307-586-3700 or visit bighornarmory.com.<\/a> <\/p>\n\n\n\n

Editor's Take: <\/h4>\n\n\n\n

The 500 Auto Max comprises a rimless 500 S&W. Magnum. Available factory ammo features bullet weights ranging from 350 to 600 grains. Handloaders get to work from 275 all the way up to a massive 700 grains. So this means you can really dial in on working up the right load to the particular application. Bullets also come in hard cast, jacketed hollow points and even monolithic solids. So there's a lot a good gun geek can really hone in on here in terms of performance. <\/p>\n\n\n\n

\"Fired<\/figure>\n\n\n\n

But we can geek out even more. The 500 Auto Max, according to data provided by Big Horn Armory, pushed a 400-grain bullet to a 2,275 fps muzzle velocity out of an 18-inch barrel in the BHA AR500. That outperforms well-known thumpers like the .45-70 and .450 Marlin with comparable bullet weights. <\/p>\n","post_title":"Big Horn Armory's AR500 Starter Kit Brings Big-Bore Hunting Power","post_excerpt":"","post_status":"publish","comment_status":"open","ping_status":"open","post_password":"","post_name":"bha-ar500-starter-kit","to_ping":"","pinged":"","post_modified":"2023-05-31 10:13:34","post_modified_gmt":"2023-05-31 10:13:34","post_content_filtered":"","post_parent":0,"guid":"https:\/\/www.athlonoutdoors.com\/2022\/04\/21\/bha-ar500-starter-kit\/","menu_order":0,"post_type":"post","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":157150,"post_author":"284","post_date":"2013-01-01 13:51:54","post_date_gmt":"2013-01-01 19:51:54","post_content":"It's not a big .50 BMG, but the Weatherby Mark V TRR and their .338-378 load can blow the socks off anything else at ultra-long range<\/em>\n\nRifle shooting seems to go in phases in America, and right now it\u2019s long-range shooting\u2019s time to shine. American shooters are fascinated with the concept of reaching out and smacking targets so far away that they clang with a different accent.\n\nIt wasn\u2019t so long ago that we thought 500 yards was \u201clong range.\u201d Then 1,000 yards became the new normal. Now it starts getting interesting for a lot of shooters at 1,500 yards.\n\nIn recent years the .338 Lapua has emerged as the premier long-range sniper rifle cartridge. That\u2019s because for shooting at ultra-long range, 1,000 yards and beyond, many believe it\u2019s the cartridge that best achieves balance.\n\n\"d15236_phatch\"<\/a>\nWeatherby Mark V Sub-MOA Threat Response rifle features an oversize bolt handle for ease of operation<\/em>\n\nThe .50 BMG is not much fun to shoot for extended periods of time with all the blast and recoil. I have seen the muzzle brake on a fifty clear a shooting bench, even send a chronograph flying. Once I witnessed ammo boxes being blown off the bench along with a bag of potato chips turned into airborne confetti. That kind of blast level can wear on a shooter after multiple shots.\n\nOn the other end of the sniper cartridge spectrum is the .308 Winchester, which is running out of steam at 1,000 yards and is completely outclassed at 1,500 yards. The Lapua splits the difference and has proven that a big, heavy, high B.C. bullet is the key. Most .338 Lapua rifles weigh less than 20 pounds so they are easily transported. With that weight class and a good muzzle brake, the .338 Lapua is easy on the shooter with mild recoil and muzzle blast.\n\nThe .338 Lapua owes its success to two things: first it\u2019s a good cartridge, but perhaps even more important, it\u2019s had great marketing. Of course it doesn\u2019t hurt that the .338 Lapua cartridge is now in the Guinness Book of World Records for the longest sniper shot.\n\nA British sniper named Craig Harrison fired three shots with his Accuracy International .338 Lapua rifle during an altercation in the sandbox. The first round hit a bad guy running a machine gun and killed him. Another insurgent stepped up to the machine gun and a second bullet killed him. The third shot took out the machine gun. The distance was measured by GPS at 2,707 yards or 1.54 miles. That\u2019s long enough that, according to my ballistic program, it took the bullets more than five seconds to get there.\n\nMilitary Roots<\/strong>\n\nThe main reason that the .338 Lapua has become so popular is because the military is using it for long-range work. Selection by the military will all but guarantee the popularity of any cartridge. Note the four most popular sniper rifle cartridges, the .308, .300 Win, .338 Lapua and the .50 BMG. They are all popular because the military uses them. But other than the .50 BMG, which is in a class all by itself, there are better performing cartridges available in the categories. They fail to achieve the degree of success, not because of any technical reason, but because of the military connection. But civilians are not bound by military selection and we can pick the cartridge that works best, not the one that some politicized General says we must use.\n\nThe .338 Lapua was developed with the 250-grain bullet in mind. Lately there is a move to 300-grain bullets, but at least for now the 250-grain is still the cartridge standard. Federal\u2019s most popular .338 Lapua load uses a 250-grain MatchKing bullet with a peak B.C. of 0.606 and a M.V. of 2,950 fps. While that\u2019s a respectable muzzle velocity, there is at least one commercial cartridge capable of driving the same bullet even faster, the .338-378 Weatherby.\n\nWeatherby\u2019s .338<\/strong>\n\n\"d14080_phatch\"<\/a>\nThe .338-378 uses the .378 Weatherby case necked down to take a .338 bullet, resulting in a sizeable cartridge with a 20-percent increase in case capacity<\/em>\n\nLike all the Weatherby rifle cartridges, the .338-378 was developed for hunting. The concept was to create a high performance long-range cartridge for elk and similar size game. But, long range shooting is long range shooting regardless if the target is an elk or a steel gong. The only requirement is simply that the rifle delivers a bullet to the target. If there is a cartridge that gets it there faster and hits the target harder, then where is the downside?\n\nThe .338-378 Weatherby cartridge uses the .378 Weatherby case, necked down to take a .338 bullet. That means it is a whopping big cartridge case. The .338-378 Weatherby case holds 137 grains of water compared to the .338 Lapua, which holds 114 grains of water. That\u2019s about a 20 percent increase in case capacity. More capacity means more propellant and more propellant means higher muzzle velocity. While the laws of diminishing returns start to apply with this big case, it still can push the same bullet substantially faster than the Lapua. That means the bullet gets to the target faster, retains more energy and has a flatter trajectory curve.\n\nWeatherby lists the muzzle velocity of their 250-grain Nosler Partition load at 3,060 fps. Hodgdon\u2019s online handloading data lists the .338-378 Weatherby with a 250-grain bullet with a statistically identical muzzle velocity of 3,072 fps. That\u2019s faster than anything else that is pushing the same diameter and weight bullet.\n\nUsing a 250-yard zero, by the time the bullet is at 1,500 yards that little bit of extra velocity has the point of impact for the .338-378 at 73.19 inches higher than the .338 Lapua. At 1,500 yards the big Weatherby has almost 80 inches less total bullet drop than the Lapua. Another big issue at ultra-long range, one that is often not considered by most shooters, is retained energy. All cartridges are dropping to low energy levels at 1,500 yards. For example, the .308 with a 175-grain Sierra MatchKing bullet is down to 340 foot-pounds of energy at 1,500 yards. That\u2019s about the same as a 9mm pistol at the muzzle.\n\n\"d14168_phatch\"<\/a>\n\nThe .338 Lapua has 763 foot-pounds of retained energy at 1,500 yards while the .338-378 has 831 foot-pounds. That\u2019s nearly a 10% increase and at that distance every foot-pound counts.\n\nThere is no question that assuming equal accuracy, the .338-378 Weatherby deserves consideration by the long-range shooting crowd and that it can surpass the performance of their current darling, the .338 Lapua.\n\nThe problem was that until now you could only find the .338-378 in a hunting style rifle. If you wanted it in a tactical, long-range configuration you had to have it custom built. But that\u2019s changed.\n\nThreat Response .338-378<\/strong>\n\nWeatherby has entered into the long-range tactical rifle market recently with their Range Certified, Mark V Threat Response Rifle. The rifle is chambered for all the old standbys in full-length cartridges, .300 Winchester, .300 Weatherby and .30-378 Weatherby. That last cartridge can do for the 30-calibers what the .338-378 does for the 33s\u2014push any given bullet weight out the muzzle faster than any other 30-caliber cartridge. The rifle is, of course, offered in .338-378 Weatherby and, new for 2012, the .338 Lapua.\n\nThe rifle features a Krieger barrel with cut rifling. It\u2019s a #3 contour 26-inch fluted barrel with a big muzzle brake fitted on the end that has five slots on each side. The twist rate is 1:10, so the rifle can use bullets weighing 300 grains. The barrel is fully free-floated clear back to the action.\n\nThe camo stock has a flat-bottom forend to sit well in sandbags, as well as a metal slot for a swivel stud to attach a bi-pod. This slot allows 9 inches of adjustment for the stud placement. The stock has an adjustable comb that is locked securely in place with two Allen head screws. The stock is adjustable for length of pull with removable spacers from 13.25 inches to 14.75 inches. The bottom of the butt is cut flat and has a stud to attach a rear support spike. The pistol grip is large and drops almost straight down to position the hand behind the trigger.\n\nThe bolt has an extended oversize knob. The push feed bolt has a spring-loaded plunger in the face for an ejector and a pivoting, spring loaded extractor fitted to the bolt.\n\nThe bolt is classic Weatherby Mark V with nine locking lugs. This means a shorter 54-degree rotation to open the bolt, which makes it faster to operate. The Mark V uses a full-size, fluted bolt body running inside the tubular action. There is no binding and it runs smooth. The bolt head is actually smaller than the bolt body. According to a Weatherby representative, that is why they do not use a removable box magazine.\n\n\"d15244_phatch\"<\/a>\n\nNot having a removable box magazine is one of the few criticisms I have of the rifle. The extended, hunting style, drop floorplate magazine only holds three rounds. It\u2019s also a bit slow to reload as the loaded cartridges are longer than the loading port, so they must be put in point first and then moved back to position as they are pushed down into the magazine.\n\nThere is a large two-position safety on the right side of the action. It rotates forward for fire and back for safe. The trigger on my sample breaks cleanly at 3 pounds, 3 ounces.\n\nI ordered a rail style scope mount from Evolution Gun Works, Inc. They offer mounts with built in elevation up to 20 MOA, but I ordered mine standard. I fitted the gun with a Swarovski 6-24x50 scope (swarovskioptik.us). The clear optics and reliable repeatability of the adjustments make this a good choice for this rifle.\n\n\"d15246_phatch\"<\/a>\nThe Weatherby .338-378 was developed to create a high-performance cartridge for hunting monster bull elk and similar big-game species at long range<\/em>\n\nFeeding The Beast<\/strong>\n\nThe other downside of this cartridge for long-range shooting is that ammo is only available from Weatherby and so far they only make hunting style ammo. It\u2019s available in three configurations; a 200-grain Nosler Accubond bullet at 3,380 fps muzzle velocity. This bullet has a B. C. of .414, which is not horrible, so it can work pretty well for long-range work. The next load has a 225-grain Barnes TSX bullet with a muzzle velocity of 3,180 and a B.C. of .482. The final load is a 250-grain Nosler Partition bullet at 3,060 fps with a B.C. of .482. I was only able to test the first two in my rifle as the Partition load was out of stock. The accuracy for five-shot groups was a little disappointing, but I suspect it\u2019s ammo more than the rifle. To make this rifle perform for long-range work, both in accuracy and in exterior ballistics, is going to require handloading. But, then again, anybody serious about precision shooting is likely going to handload. My guess is the 250-grain and 300-grain bullets that are offered will really make this gun step up and shine. The 250-grain can be driven to 3,072 fps according to Hodgdon. The 300-grain Sierra will exit at 2,818 and is an even better performer at ultra-long range than the 250-grain, due to the ultra-high ballistic coefficient.\n\nIf you want the biggest, baddest, 33-caliber long-range commercial cartridge on the planet and you don\u2019t mind working a bit to build the ammo, check out this new Weatherby TRR. It can blow the socks off anything else at ultra-long range.

It\u2019s also a bit slow to reload as the loaded cartridges are longer than the loading port, so they must be put in point first and then moved back to position as they are pushed down into the magazine.\n\nThere is a large two-position safety on the right side of the action. It rotates forward for fire and back for safe. The trigger on my sample breaks cleanly at 3 pounds, 3 ounces.\n\nI ordered a rail style scope mount from Evolution Gun Works, Inc. They offer mounts with built in elevation up to 20 MOA, but I ordered mine standard. I fitted the gun with a Swarovski 6-24x50 scope (swarovskioptik.us). The clear optics and reliable repeatability of the adjustments make this a good choice for this rifle.\n\n\"d15246_phatch\"<\/a>\nThe Weatherby .338-378 was developed to create a high-performance cartridge for hunting monster bull elk and similar big-game species at long range<\/em>\n\nFeeding The Beast<\/strong>\n\nThe other downside of this cartridge for long-range shooting is that ammo is only available from Weatherby and so far they only make hunting style ammo. It\u2019s available in three configurations; a 200-grain Nosler Accubond bullet at 3,380 fps muzzle velocity. This bullet has a B. C. of .414, which is not horrible, so it can work pretty well for long-range work. The next load has a 225-grain Barnes TSX bullet with a muzzle velocity of 3,180 and a B.C. of .482. The final load is a 250-grain Nosler Partition bullet at 3,060 fps with a B.C. of .482. I was only able to test the first two in my rifle as the Partition load was out of stock. The accuracy for five-shot groups was a little disappointing, but I suspect it\u2019s ammo more than the rifle. To make this rifle perform for long-range work, both in accuracy and in exterior ballistics, is going to require handloading. But, then again, anybody serious about precision shooting is likely going to handload. My guess is the 250-grain and 300-grain bullets that are offered will really make this gun step up and shine. The 250-grain can be driven to 3,072 fps according to Hodgdon. The 300-grain Sierra will exit at 2,818 and is an even better performer at ultra-long range than the 250-grain, due to the ultra-high ballistic coefficient.\n\nIf you want the biggest, baddest, 33-caliber long-range commercial cartridge on the planet and you don\u2019t mind working a bit to build the ammo, check out this new Weatherby TRR. It can blow the socks off anything else at ultra-long range.

Big Horn Armory AR500 Starter Kit<\/h2>\n\n\n\n

First off, the package brings a serious ammo discount right out of the gate. With prices often topping $4.50 per round, the AR500 Starter Kit puts the 500 Auto Max at $2 per round. Buffalo Bore, Steinel Ammunition and Underwood Ammunition all provide factory loads for the 500 Auto Max.<\/p>\n\n\n\n

Better still, the package includes the BHA AR500 rifle<\/a>. Chambered in 500 Auto Max, this modern sporting rifle brings serious thump. For AR users, within that familiar manual of arms, shooters get uncommon knockdown power in a short- to medium-range cartridge. Big Horn Armory even offers a braced-pistol variant if you seek a compact field gun. <\/p>\n\n\n\n

Big Horn Armory cautioned this one will only be available for a limited time. For more info, call 307-586-3700 or visit bighornarmory.com.<\/a> <\/p>\n\n\n\n

Editor's Take: <\/h4>\n\n\n\n

The 500 Auto Max comprises a rimless 500 S&W. Magnum. Available factory ammo features bullet weights ranging from 350 to 600 grains. Handloaders get to work from 275 all the way up to a massive 700 grains. So this means you can really dial in on working up the right load to the particular application. Bullets also come in hard cast, jacketed hollow points and even monolithic solids. So there's a lot a good gun geek can really hone in on here in terms of performance. <\/p>\n\n\n\n

\"Fired<\/figure>\n\n\n\n

But we can geek out even more. The 500 Auto Max, according to data provided by Big Horn Armory, pushed a 400-grain bullet to a 2,275 fps muzzle velocity out of an 18-inch barrel in the BHA AR500. That outperforms well-known thumpers like the .45-70 and .450 Marlin with comparable bullet weights. <\/p>\n","post_title":"Big Horn Armory's AR500 Starter Kit Brings Big-Bore Hunting Power","post_excerpt":"","post_status":"publish","comment_status":"open","ping_status":"open","post_password":"","post_name":"bha-ar500-starter-kit","to_ping":"","pinged":"","post_modified":"2023-05-31 10:13:34","post_modified_gmt":"2023-05-31 10:13:34","post_content_filtered":"","post_parent":0,"guid":"https:\/\/www.athlonoutdoors.com\/2022\/04\/21\/bha-ar500-starter-kit\/","menu_order":0,"post_type":"post","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":157150,"post_author":"284","post_date":"2013-01-01 13:51:54","post_date_gmt":"2013-01-01 19:51:54","post_content":"It's not a big .50 BMG, but the Weatherby Mark V TRR and their .338-378 load can blow the socks off anything else at ultra-long range<\/em>\n\nRifle shooting seems to go in phases in America, and right now it\u2019s long-range shooting\u2019s time to shine. American shooters are fascinated with the concept of reaching out and smacking targets so far away that they clang with a different accent.\n\nIt wasn\u2019t so long ago that we thought 500 yards was \u201clong range.\u201d Then 1,000 yards became the new normal. Now it starts getting interesting for a lot of shooters at 1,500 yards.\n\nIn recent years the .338 Lapua has emerged as the premier long-range sniper rifle cartridge. That\u2019s because for shooting at ultra-long range, 1,000 yards and beyond, many believe it\u2019s the cartridge that best achieves balance.\n\n\"d15236_phatch\"<\/a>\nWeatherby Mark V Sub-MOA Threat Response rifle features an oversize bolt handle for ease of operation<\/em>\n\nThe .50 BMG is not much fun to shoot for extended periods of time with all the blast and recoil. I have seen the muzzle brake on a fifty clear a shooting bench, even send a chronograph flying. Once I witnessed ammo boxes being blown off the bench along with a bag of potato chips turned into airborne confetti. That kind of blast level can wear on a shooter after multiple shots.\n\nOn the other end of the sniper cartridge spectrum is the .308 Winchester, which is running out of steam at 1,000 yards and is completely outclassed at 1,500 yards. The Lapua splits the difference and has proven that a big, heavy, high B.C. bullet is the key. Most .338 Lapua rifles weigh less than 20 pounds so they are easily transported. With that weight class and a good muzzle brake, the .338 Lapua is easy on the shooter with mild recoil and muzzle blast.\n\nThe .338 Lapua owes its success to two things: first it\u2019s a good cartridge, but perhaps even more important, it\u2019s had great marketing. Of course it doesn\u2019t hurt that the .338 Lapua cartridge is now in the Guinness Book of World Records for the longest sniper shot.\n\nA British sniper named Craig Harrison fired three shots with his Accuracy International .338 Lapua rifle during an altercation in the sandbox. The first round hit a bad guy running a machine gun and killed him. Another insurgent stepped up to the machine gun and a second bullet killed him. The third shot took out the machine gun. The distance was measured by GPS at 2,707 yards or 1.54 miles. That\u2019s long enough that, according to my ballistic program, it took the bullets more than five seconds to get there.\n\nMilitary Roots<\/strong>\n\nThe main reason that the .338 Lapua has become so popular is because the military is using it for long-range work. Selection by the military will all but guarantee the popularity of any cartridge. Note the four most popular sniper rifle cartridges, the .308, .300 Win, .338 Lapua and the .50 BMG. They are all popular because the military uses them. But other than the .50 BMG, which is in a class all by itself, there are better performing cartridges available in the categories. They fail to achieve the degree of success, not because of any technical reason, but because of the military connection. But civilians are not bound by military selection and we can pick the cartridge that works best, not the one that some politicized General says we must use.\n\nThe .338 Lapua was developed with the 250-grain bullet in mind. Lately there is a move to 300-grain bullets, but at least for now the 250-grain is still the cartridge standard. Federal\u2019s most popular .338 Lapua load uses a 250-grain MatchKing bullet with a peak B.C. of 0.606 and a M.V. of 2,950 fps. While that\u2019s a respectable muzzle velocity, there is at least one commercial cartridge capable of driving the same bullet even faster, the .338-378 Weatherby.\n\nWeatherby\u2019s .338<\/strong>\n\n\"d14080_phatch\"<\/a>\nThe .338-378 uses the .378 Weatherby case necked down to take a .338 bullet, resulting in a sizeable cartridge with a 20-percent increase in case capacity<\/em>\n\nLike all the Weatherby rifle cartridges, the .338-378 was developed for hunting. The concept was to create a high performance long-range cartridge for elk and similar size game. But, long range shooting is long range shooting regardless if the target is an elk or a steel gong. The only requirement is simply that the rifle delivers a bullet to the target. If there is a cartridge that gets it there faster and hits the target harder, then where is the downside?\n\nThe .338-378 Weatherby cartridge uses the .378 Weatherby case, necked down to take a .338 bullet. That means it is a whopping big cartridge case. The .338-378 Weatherby case holds 137 grains of water compared to the .338 Lapua, which holds 114 grains of water. That\u2019s about a 20 percent increase in case capacity. More capacity means more propellant and more propellant means higher muzzle velocity. While the laws of diminishing returns start to apply with this big case, it still can push the same bullet substantially faster than the Lapua. That means the bullet gets to the target faster, retains more energy and has a flatter trajectory curve.\n\nWeatherby lists the muzzle velocity of their 250-grain Nosler Partition load at 3,060 fps. Hodgdon\u2019s online handloading data lists the .338-378 Weatherby with a 250-grain bullet with a statistically identical muzzle velocity of 3,072 fps. That\u2019s faster than anything else that is pushing the same diameter and weight bullet.\n\nUsing a 250-yard zero, by the time the bullet is at 1,500 yards that little bit of extra velocity has the point of impact for the .338-378 at 73.19 inches higher than the .338 Lapua. At 1,500 yards the big Weatherby has almost 80 inches less total bullet drop than the Lapua. Another big issue at ultra-long range, one that is often not considered by most shooters, is retained energy. All cartridges are dropping to low energy levels at 1,500 yards. For example, the .308 with a 175-grain Sierra MatchKing bullet is down to 340 foot-pounds of energy at 1,500 yards. That\u2019s about the same as a 9mm pistol at the muzzle.\n\n\"d14168_phatch\"<\/a>\n\nThe .338 Lapua has 763 foot-pounds of retained energy at 1,500 yards while the .338-378 has 831 foot-pounds. That\u2019s nearly a 10% increase and at that distance every foot-pound counts.\n\nThere is no question that assuming equal accuracy, the .338-378 Weatherby deserves consideration by the long-range shooting crowd and that it can surpass the performance of their current darling, the .338 Lapua.\n\nThe problem was that until now you could only find the .338-378 in a hunting style rifle. If you wanted it in a tactical, long-range configuration you had to have it custom built. But that\u2019s changed.\n\nThreat Response .338-378<\/strong>\n\nWeatherby has entered into the long-range tactical rifle market recently with their Range Certified, Mark V Threat Response Rifle. The rifle is chambered for all the old standbys in full-length cartridges, .300 Winchester, .300 Weatherby and .30-378 Weatherby. That last cartridge can do for the 30-calibers what the .338-378 does for the 33s\u2014push any given bullet weight out the muzzle faster than any other 30-caliber cartridge. The rifle is, of course, offered in .338-378 Weatherby and, new for 2012, the .338 Lapua.\n\nThe rifle features a Krieger barrel with cut rifling. It\u2019s a #3 contour 26-inch fluted barrel with a big muzzle brake fitted on the end that has five slots on each side. The twist rate is 1:10, so the rifle can use bullets weighing 300 grains. The barrel is fully free-floated clear back to the action.\n\nThe camo stock has a flat-bottom forend to sit well in sandbags, as well as a metal slot for a swivel stud to attach a bi-pod. This slot allows 9 inches of adjustment for the stud placement. The stock has an adjustable comb that is locked securely in place with two Allen head screws. The stock is adjustable for length of pull with removable spacers from 13.25 inches to 14.75 inches. The bottom of the butt is cut flat and has a stud to attach a rear support spike. The pistol grip is large and drops almost straight down to position the hand behind the trigger.\n\nThe bolt has an extended oversize knob. The push feed bolt has a spring-loaded plunger in the face for an ejector and a pivoting, spring loaded extractor fitted to the bolt.\n\nThe bolt is classic Weatherby Mark V with nine locking lugs. This means a shorter 54-degree rotation to open the bolt, which makes it faster to operate. The Mark V uses a full-size, fluted bolt body running inside the tubular action. There is no binding and it runs smooth. The bolt head is actually smaller than the bolt body. According to a Weatherby representative, that is why they do not use a removable box magazine.\n\n\"d15244_phatch\"<\/a>\n\nNot having a removable box magazine is one of the few criticisms I have of the rifle. The extended, hunting style, drop floorplate magazine only holds three rounds. It\u2019s also a bit slow to reload as the loaded cartridges are longer than the loading port, so they must be put in point first and then moved back to position as they are pushed down into the magazine.\n\nThere is a large two-position safety on the right side of the action. It rotates forward for fire and back for safe. The trigger on my sample breaks cleanly at 3 pounds, 3 ounces.\n\nI ordered a rail style scope mount from Evolution Gun Works, Inc. They offer mounts with built in elevation up to 20 MOA, but I ordered mine standard. I fitted the gun with a Swarovski 6-24x50 scope (swarovskioptik.us). The clear optics and reliable repeatability of the adjustments make this a good choice for this rifle.\n\n\"d15246_phatch\"<\/a>\nThe Weatherby .338-378 was developed to create a high-performance cartridge for hunting monster bull elk and similar big-game species at long range<\/em>\n\nFeeding The Beast<\/strong>\n\nThe other downside of this cartridge for long-range shooting is that ammo is only available from Weatherby and so far they only make hunting style ammo. It\u2019s available in three configurations; a 200-grain Nosler Accubond bullet at 3,380 fps muzzle velocity. This bullet has a B. C. of .414, which is not horrible, so it can work pretty well for long-range work. The next load has a 225-grain Barnes TSX bullet with a muzzle velocity of 3,180 and a B.C. of .482. The final load is a 250-grain Nosler Partition bullet at 3,060 fps with a B.C. of .482. I was only able to test the first two in my rifle as the Partition load was out of stock.

That\u2019s about the same as a 9mm pistol at the muzzle.\n\n\"d14168_phatch\"<\/a>\n\nThe .338 Lapua has 763 foot-pounds of retained energy at 1,500 yards while the .338-378 has 831 foot-pounds. That\u2019s nearly a 10% increase and at that distance every foot-pound counts.\n\nThere is no question that assuming equal accuracy, the .338-378 Weatherby deserves consideration by the long-range shooting crowd and that it can surpass the performance of their current darling, the .338 Lapua.\n\nThe problem was that until now you could only find the .338-378 in a hunting style rifle. If you wanted it in a tactical, long-range configuration you had to have it custom built. But that\u2019s changed.\n\nThreat Response .338-378<\/strong>\n\nWeatherby has entered into the long-range tactical rifle market recently with their Range Certified, Mark V Threat Response Rifle. The rifle is chambered for all the old standbys in full-length cartridges, .300 Winchester, .300 Weatherby and .30-378 Weatherby. That last cartridge can do for the 30-calibers what the .338-378 does for the 33s\u2014push any given bullet weight out the muzzle faster than any other 30-caliber cartridge. The rifle is, of course, offered in .338-378 Weatherby and, new for 2012, the .338 Lapua.\n\nThe rifle features a Krieger barrel with cut rifling. It\u2019s a #3 contour 26-inch fluted barrel with a big muzzle brake fitted on the end that has five slots on each side. The twist rate is 1:10, so the rifle can use bullets weighing 300 grains. The barrel is fully free-floated clear back to the action.\n\nThe camo stock has a flat-bottom forend to sit well in sandbags, as well as a metal slot for a swivel stud to attach a bi-pod. This slot allows 9 inches of adjustment for the stud placement. The stock has an adjustable comb that is locked securely in place with two Allen head screws. The stock is adjustable for length of pull with removable spacers from 13.25 inches to 14.75 inches. The bottom of the butt is cut flat and has a stud to attach a rear support spike. The pistol grip is large and drops almost straight down to position the hand behind the trigger.\n\nThe bolt has an extended oversize knob. The push feed bolt has a spring-loaded plunger in the face for an ejector and a pivoting, spring loaded extractor fitted to the bolt.\n\nThe bolt is classic Weatherby Mark V with nine locking lugs. This means a shorter 54-degree rotation to open the bolt, which makes it faster to operate. The Mark V uses a full-size, fluted bolt body running inside the tubular action. There is no binding and it runs smooth. The bolt head is actually smaller than the bolt body. According to a Weatherby representative, that is why they do not use a removable box magazine.\n\n\"d15244_phatch\"<\/a>\n\nNot having a removable box magazine is one of the few criticisms I have of the rifle. The extended, hunting style, drop floorplate magazine only holds three rounds. It\u2019s also a bit slow to reload as the loaded cartridges are longer than the loading port, so they must be put in point first and then moved back to position as they are pushed down into the magazine.\n\nThere is a large two-position safety on the right side of the action. It rotates forward for fire and back for safe. The trigger on my sample breaks cleanly at 3 pounds, 3 ounces.\n\nI ordered a rail style scope mount from Evolution Gun Works, Inc. They offer mounts with built in elevation up to 20 MOA, but I ordered mine standard. I fitted the gun with a Swarovski 6-24x50 scope (swarovskioptik.us). The clear optics and reliable repeatability of the adjustments make this a good choice for this rifle.\n\n\"d15246_phatch\"<\/a>\nThe Weatherby .338-378 was developed to create a high-performance cartridge for hunting monster bull elk and similar big-game species at long range<\/em>\n\nFeeding The Beast<\/strong>\n\nThe other downside of this cartridge for long-range shooting is that ammo is only available from Weatherby and so far they only make hunting style ammo. It\u2019s available in three configurations; a 200-grain Nosler Accubond bullet at 3,380 fps muzzle velocity. This bullet has a B. C. of .414, which is not horrible, so it can work pretty well for long-range work. The next load has a 225-grain Barnes TSX bullet with a muzzle velocity of 3,180 and a B.C. of .482. The final load is a 250-grain Nosler Partition bullet at 3,060 fps with a B.C. of .482. I was only able to test the first two in my rifle as the Partition load was out of stock. The accuracy for five-shot groups was a little disappointing, but I suspect it\u2019s ammo more than the rifle. To make this rifle perform for long-range work, both in accuracy and in exterior ballistics, is going to require handloading. But, then again, anybody serious about precision shooting is likely going to handload. My guess is the 250-grain and 300-grain bullets that are offered will really make this gun step up and shine. The 250-grain can be driven to 3,072 fps according to Hodgdon. The 300-grain Sierra will exit at 2,818 and is an even better performer at ultra-long range than the 250-grain, due to the ultra-high ballistic coefficient.\n\nIf you want the biggest, baddest, 33-caliber long-range commercial cartridge on the planet and you don\u2019t mind working a bit to build the ammo, check out this new Weatherby TRR. It can blow the socks off anything else at ultra-long range.

Looking to try something a little different for your next hunting trip? The Big Horn Armory AR500 Starter Kit packages serious big-bore power, putting everything you need into one convenient bundle. The package includes a Big Horn Armory AR chambered in 500 Auto Max and 100 rounds of ammunition. <\/p>\n\n\n\n\n\n

Big Horn Armory AR500 Starter Kit<\/h2>\n\n\n\n

First off, the package brings a serious ammo discount right out of the gate. With prices often topping $4.50 per round, the AR500 Starter Kit puts the 500 Auto Max at $2 per round. Buffalo Bore, Steinel Ammunition and Underwood Ammunition all provide factory loads for the 500 Auto Max.<\/p>\n\n\n\n

Better still, the package includes the BHA AR500 rifle<\/a>. Chambered in 500 Auto Max, this modern sporting rifle brings serious thump. For AR users, within that familiar manual of arms, shooters get uncommon knockdown power in a short- to medium-range cartridge. Big Horn Armory even offers a braced-pistol variant if you seek a compact field gun. <\/p>\n\n\n\n

Big Horn Armory cautioned this one will only be available for a limited time. For more info, call 307-586-3700 or visit bighornarmory.com.<\/a> <\/p>\n\n\n\n

Editor's Take: <\/h4>\n\n\n\n

The 500 Auto Max comprises a rimless 500 S&W. Magnum. Available factory ammo features bullet weights ranging from 350 to 600 grains. Handloaders get to work from 275 all the way up to a massive 700 grains. So this means you can really dial in on working up the right load to the particular application. Bullets also come in hard cast, jacketed hollow points and even monolithic solids. So there's a lot a good gun geek can really hone in on here in terms of performance. <\/p>\n\n\n\n

\"Fired<\/figure>\n\n\n\n

But we can geek out even more. The 500 Auto Max, according to data provided by Big Horn Armory, pushed a 400-grain bullet to a 2,275 fps muzzle velocity out of an 18-inch barrel in the BHA AR500. That outperforms well-known thumpers like the .45-70 and .450 Marlin with comparable bullet weights. <\/p>\n","post_title":"Big Horn Armory's AR500 Starter Kit Brings Big-Bore Hunting Power","post_excerpt":"","post_status":"publish","comment_status":"open","ping_status":"open","post_password":"","post_name":"bha-ar500-starter-kit","to_ping":"","pinged":"","post_modified":"2023-05-31 10:13:34","post_modified_gmt":"2023-05-31 10:13:34","post_content_filtered":"","post_parent":0,"guid":"https:\/\/www.athlonoutdoors.com\/2022\/04\/21\/bha-ar500-starter-kit\/","menu_order":0,"post_type":"post","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":157150,"post_author":"284","post_date":"2013-01-01 13:51:54","post_date_gmt":"2013-01-01 19:51:54","post_content":"It's not a big .50 BMG, but the Weatherby Mark V TRR and their .338-378 load can blow the socks off anything else at ultra-long range<\/em>\n\nRifle shooting seems to go in phases in America, and right now it\u2019s long-range shooting\u2019s time to shine. American shooters are fascinated with the concept of reaching out and smacking targets so far away that they clang with a different accent.\n\nIt wasn\u2019t so long ago that we thought 500 yards was \u201clong range.\u201d Then 1,000 yards became the new normal. Now it starts getting interesting for a lot of shooters at 1,500 yards.\n\nIn recent years the .338 Lapua has emerged as the premier long-range sniper rifle cartridge. That\u2019s because for shooting at ultra-long range, 1,000 yards and beyond, many believe it\u2019s the cartridge that best achieves balance.\n\n\"d15236_phatch\"<\/a>\nWeatherby Mark V Sub-MOA Threat Response rifle features an oversize bolt handle for ease of operation<\/em>\n\nThe .50 BMG is not much fun to shoot for extended periods of time with all the blast and recoil. I have seen the muzzle brake on a fifty clear a shooting bench, even send a chronograph flying. Once I witnessed ammo boxes being blown off the bench along with a bag of potato chips turned into airborne confetti. That kind of blast level can wear on a shooter after multiple shots.\n\nOn the other end of the sniper cartridge spectrum is the .308 Winchester, which is running out of steam at 1,000 yards and is completely outclassed at 1,500 yards. The Lapua splits the difference and has proven that a big, heavy, high B.C. bullet is the key. Most .338 Lapua rifles weigh less than 20 pounds so they are easily transported. With that weight class and a good muzzle brake, the .338 Lapua is easy on the shooter with mild recoil and muzzle blast.\n\nThe .338 Lapua owes its success to two things: first it\u2019s a good cartridge, but perhaps even more important, it\u2019s had great marketing. Of course it doesn\u2019t hurt that the .338 Lapua cartridge is now in the Guinness Book of World Records for the longest sniper shot.\n\nA British sniper named Craig Harrison fired three shots with his Accuracy International .338 Lapua rifle during an altercation in the sandbox. The first round hit a bad guy running a machine gun and killed him. Another insurgent stepped up to the machine gun and a second bullet killed him. The third shot took out the machine gun. The distance was measured by GPS at 2,707 yards or 1.54 miles. That\u2019s long enough that, according to my ballistic program, it took the bullets more than five seconds to get there.\n\nMilitary Roots<\/strong>\n\nThe main reason that the .338 Lapua has become so popular is because the military is using it for long-range work. Selection by the military will all but guarantee the popularity of any cartridge. Note the four most popular sniper rifle cartridges, the .308, .300 Win, .338 Lapua and the .50 BMG. They are all popular because the military uses them. But other than the .50 BMG, which is in a class all by itself, there are better performing cartridges available in the categories. They fail to achieve the degree of success, not because of any technical reason, but because of the military connection. But civilians are not bound by military selection and we can pick the cartridge that works best, not the one that some politicized General says we must use.\n\nThe .338 Lapua was developed with the 250-grain bullet in mind. Lately there is a move to 300-grain bullets, but at least for now the 250-grain is still the cartridge standard. Federal\u2019s most popular .338 Lapua load uses a 250-grain MatchKing bullet with a peak B.C. of 0.606 and a M.V. of 2,950 fps. While that\u2019s a respectable muzzle velocity, there is at least one commercial cartridge capable of driving the same bullet even faster, the .338-378 Weatherby.\n\nWeatherby\u2019s .338<\/strong>\n\n\"d14080_phatch\"<\/a>\nThe .338-378 uses the .378 Weatherby case necked down to take a .338 bullet, resulting in a sizeable cartridge with a 20-percent increase in case capacity<\/em>\n\nLike all the Weatherby rifle cartridges, the .338-378 was developed for hunting. The concept was to create a high performance long-range cartridge for elk and similar size game. But, long range shooting is long range shooting regardless if the target is an elk or a steel gong. The only requirement is simply that the rifle delivers a bullet to the target. If there is a cartridge that gets it there faster and hits the target harder, then where is the downside?\n\nThe .338-378 Weatherby cartridge uses the .378 Weatherby case, necked down to take a .338 bullet. That means it is a whopping big cartridge case. The .338-378 Weatherby case holds 137 grains of water compared to the .338 Lapua, which holds 114 grains of water. That\u2019s about a 20 percent increase in case capacity. More capacity means more propellant and more propellant means higher muzzle velocity. While the laws of diminishing returns start to apply with this big case, it still can push the same bullet substantially faster than the Lapua. That means the bullet gets to the target faster, retains more energy and has a flatter trajectory curve.\n\nWeatherby lists the muzzle velocity of their 250-grain Nosler Partition load at 3,060 fps. Hodgdon\u2019s online handloading data lists the .338-378 Weatherby with a 250-grain bullet with a statistically identical muzzle velocity of 3,072 fps. That\u2019s faster than anything else that is pushing the same diameter and weight bullet.\n\nUsing a 250-yard zero, by the time the bullet is at 1,500 yards that little bit of extra velocity has the point of impact for the .338-378 at 73.19 inches higher than the .338 Lapua. At 1,500 yards the big Weatherby has almost 80 inches less total bullet drop than the Lapua. Another big issue at ultra-long range, one that is often not considered by most shooters, is retained energy. All cartridges are dropping to low energy levels at 1,500 yards. For example, the .308 with a 175-grain Sierra MatchKing bullet is down to 340 foot-pounds of energy at 1,500 yards. That\u2019s about the same as a 9mm pistol at the muzzle.\n\n\"d14168_phatch\"<\/a>\n\nThe .338 Lapua has 763 foot-pounds of retained energy at 1,500 yards while the .338-378 has 831 foot-pounds. That\u2019s nearly a 10% increase and at that distance every foot-pound counts.\n\nThere is no question that assuming equal accuracy, the .338-378 Weatherby deserves consideration by the long-range shooting crowd and that it can surpass the performance of their current darling, the .338 Lapua.\n\nThe problem was that until now you could only find the .338-378 in a hunting style rifle. If you wanted it in a tactical, long-range configuration you had to have it custom built. But that\u2019s changed.\n\nThreat Response .338-378<\/strong>\n\nWeatherby has entered into the long-range tactical rifle market recently with their Range Certified, Mark V Threat Response Rifle. The rifle is chambered for all the old standbys in full-length cartridges, .300 Winchester, .300 Weatherby and .30-378 Weatherby. That last cartridge can do for the 30-calibers what the .338-378 does for the 33s\u2014push any given bullet weight out the muzzle faster than any other 30-caliber cartridge. The rifle is, of course, offered in .338-378 Weatherby and, new for 2012, the .338 Lapua.\n\nThe rifle features a Krieger barrel with cut rifling. It\u2019s a #3 contour 26-inch fluted barrel with a big muzzle brake fitted on the end that has five slots on each side. The twist rate is 1:10, so the rifle can use bullets weighing 300 grains. The barrel is fully free-floated clear back to the action.\n\nThe camo stock has a flat-bottom forend to sit well in sandbags, as well as a metal slot for a swivel stud to attach a bi-pod. This slot allows 9 inches of adjustment for the stud placement. The stock has an adjustable comb that is locked securely in place with two Allen head screws.

It\u2019s also a bit slow to reload as the loaded cartridges are longer than the loading port, so they must be put in point first and then moved back to position as they are pushed down into the magazine.\n\nThere is a large two-position safety on the right side of the action. It rotates forward for fire and back for safe. The trigger on my sample breaks cleanly at 3 pounds, 3 ounces.\n\nI ordered a rail style scope mount from Evolution Gun Works, Inc.

Now it starts getting interesting for a lot of shooters at 1,500 yards.\n\nIn recent years the .338 Lapua has emerged as the premier long-range sniper rifle cartridge. That\u2019s because for shooting at ultra-long range, 1,000 yards and beyond, many believe it\u2019s the cartridge that best achieves balance.\n\n\"d15236_phatch\"<\/a>\nWeatherby Mark V Sub-MOA Threat Response rifle features an oversize bolt handle for ease of operation<\/em>\n\nThe .50 BMG is not much fun to shoot for extended periods of time with all the blast and recoil. I have seen the muzzle brake on a fifty clear a shooting bench, even send a chronograph flying. Once I witnessed ammo boxes being blown off the bench along with a bag of potato chips turned into airborne confetti. That kind of blast level can wear on a shooter after multiple shots.\n\nOn the other end of the sniper cartridge spectrum is the .308 Winchester, which is running out of steam at 1,000 yards and is completely outclassed at 1,500 yards. The Lapua splits the difference and has proven that a big, heavy, high B.C. bullet is the key. Most .338 Lapua rifles weigh less than 20 pounds so they are easily transported. With that weight class and a good muzzle brake, the .338 Lapua is easy on the shooter with mild recoil and muzzle blast.\n\nThe .338 Lapua owes its success to two things: first it\u2019s a good cartridge, but perhaps even more important, it\u2019s had great marketing. Of course it doesn\u2019t hurt that the .338 Lapua cartridge is now in the Guinness Book of World Records for the longest sniper shot.\n\nA British sniper named Craig Harrison fired three shots with his Accuracy International .338 Lapua rifle during an altercation in the sandbox. The first round hit a bad guy running a machine gun and killed him. Another insurgent stepped up to the machine gun and a second bullet killed him. The third shot took out the machine gun. The distance was measured by GPS at 2,707 yards or 1.54 miles. That\u2019s long enough that, according to my ballistic program, it took the bullets more than five seconds to get there.\n\nMilitary Roots<\/strong>\n\nThe main reason that the .338 Lapua has become so popular is because the military is using it for long-range work. Selection by the military will all but guarantee the popularity of any cartridge. Note the four most popular sniper rifle cartridges, the .308, .300 Win, .338 Lapua and the .50 BMG. They are all popular because the military uses them. But other than the .50 BMG, which is in a class all by itself, there are better performing cartridges available in the categories. They fail to achieve the degree of success, not because of any technical reason, but because of the military connection. But civilians are not bound by military selection and we can pick the cartridge that works best, not the one that some politicized General says we must use.\n\nThe .338 Lapua was developed with the 250-grain bullet in mind. Lately there is a move to 300-grain bullets, but at least for now the 250-grain is still the cartridge standard. Federal\u2019s most popular .338 Lapua load uses a 250-grain MatchKing bullet with a peak B.C. of 0.606 and a M.V. of 2,950 fps. While that\u2019s a respectable muzzle velocity, there is at least one commercial cartridge capable of driving the same bullet even faster, the .338-378 Weatherby.\n\nWeatherby\u2019s .338<\/strong>\n\n\"d14080_phatch\"<\/a>\nThe .338-378 uses the .378 Weatherby case necked down to take a .338 bullet, resulting in a sizeable cartridge with a 20-percent increase in case capacity<\/em>\n\nLike all the Weatherby rifle cartridges, the .338-378 was developed for hunting. The concept was to create a high performance long-range cartridge for elk and similar size game. But, long range shooting is long range shooting regardless if the target is an elk or a steel gong. The only requirement is simply that the rifle delivers a bullet to the target. If there is a cartridge that gets it there faster and hits the target harder, then where is the downside?\n\nThe .338-378 Weatherby cartridge uses the .378 Weatherby case, necked down to take a .338 bullet. That means it is a whopping big cartridge case. The .338-378 Weatherby case holds 137 grains of water compared to the .338 Lapua, which holds 114 grains of water. That\u2019s about a 20 percent increase in case capacity. More capacity means more propellant and more propellant means higher muzzle velocity. While the laws of diminishing returns start to apply with this big case, it still can push the same bullet substantially faster than the Lapua. That means the bullet gets to the target faster, retains more energy and has a flatter trajectory curve.\n\nWeatherby lists the muzzle velocity of their 250-grain Nosler Partition load at 3,060 fps. Hodgdon\u2019s online handloading data lists the .338-378 Weatherby with a 250-grain bullet with a statistically identical muzzle velocity of 3,072 fps. That\u2019s faster than anything else that is pushing the same diameter and weight bullet.\n\nUsing a 250-yard zero, by the time the bullet is at 1,500 yards that little bit of extra velocity has the point of impact for the .338-378 at 73.19 inches higher than the .338 Lapua. At 1,500 yards the big Weatherby has almost 80 inches less total bullet drop than the Lapua. Another big issue at ultra-long range, one that is often not considered by most shooters, is retained energy. All cartridges are dropping to low energy levels at 1,500 yards. For example, the .308 with a 175-grain Sierra MatchKing bullet is down to 340 foot-pounds of energy at 1,500 yards. That\u2019s about the same as a 9mm pistol at the muzzle.\n\n\"d14168_phatch\"<\/a>\n\nThe .338 Lapua has 763 foot-pounds of retained energy at 1,500 yards while the .338-378 has 831 foot-pounds. That\u2019s nearly a 10% increase and at that distance every foot-pound counts.\n\nThere is no question that assuming equal accuracy, the .338-378 Weatherby deserves consideration by the long-range shooting crowd and that it can surpass the performance of their current darling, the .338 Lapua.\n\nThe problem was that until now you could only find the .338-378 in a hunting style rifle. If you wanted it in a tactical, long-range configuration you had to have it custom built. But that\u2019s changed.\n\nThreat Response .338-378<\/strong>\n\nWeatherby has entered into the long-range tactical rifle market recently with their Range Certified, Mark V Threat Response Rifle. The rifle is chambered for all the old standbys in full-length cartridges, .300 Winchester, .300 Weatherby and .30-378 Weatherby. That last cartridge can do for the 30-calibers what the .338-378 does for the 33s\u2014push any given bullet weight out the muzzle faster than any other 30-caliber cartridge. The rifle is, of course, offered in .338-378 Weatherby and, new for 2012, the .338 Lapua.\n\nThe rifle features a Krieger barrel with cut rifling. It\u2019s a #3 contour 26-inch fluted barrel with a big muzzle brake fitted on the end that has five slots on each side. The twist rate is 1:10, so the rifle can use bullets weighing 300 grains. The barrel is fully free-floated clear back to the action.\n\nThe camo stock has a flat-bottom forend to sit well in sandbags, as well as a metal slot for a swivel stud to attach a bi-pod. This slot allows 9 inches of adjustment for the stud placement. The stock has an adjustable comb that is locked securely in place with two Allen head screws. The stock is adjustable for length of pull with removable spacers from 13.25 inches to 14.75 inches. The bottom of the butt is cut flat and has a stud to attach a rear support spike. The pistol grip is large and drops almost straight down to position the hand behind the trigger.\n\nThe bolt has an extended oversize knob. The push feed bolt has a spring-loaded plunger in the face for an ejector and a pivoting, spring loaded extractor fitted to the bolt.\n\nThe bolt is classic Weatherby Mark V with nine locking lugs. This means a shorter 54-degree rotation to open the bolt, which makes it faster to operate. The Mark V uses a full-size, fluted bolt body running inside the tubular action. There is no binding and it runs smooth. The bolt head is actually smaller than the bolt body. According to a Weatherby representative, that is why they do not use a removable box magazine.\n\n\"d15244_phatch\"<\/a>\n\nNot having a removable box magazine is one of the few criticisms I have of the rifle. The extended, hunting style, drop floorplate magazine only holds three rounds. It\u2019s also a bit slow to reload as the loaded cartridges are longer than the loading port, so they must be put in point first and then moved back to position as they are pushed down into the magazine.\n\nThere is a large two-position safety on the right side of the action. It rotates forward for fire and back for safe. The trigger on my sample breaks cleanly at 3 pounds, 3 ounces.\n\nI ordered a rail style scope mount from Evolution Gun Works, Inc. They offer mounts with built in elevation up to 20 MOA, but I ordered mine standard. I fitted the gun with a Swarovski 6-24x50 scope (swarovskioptik.us). The clear optics and reliable repeatability of the adjustments make this a good choice for this rifle.\n\n\"d15246_phatch\"<\/a>\nThe Weatherby .338-378 was developed to create a high-performance cartridge for hunting monster bull elk and similar big-game species at long range<\/em>\n\nFeeding The Beast<\/strong>\n\nThe other downside of this cartridge for long-range shooting is that ammo is only available from Weatherby and so far they only make hunting style ammo. It\u2019s available in three configurations; a 200-grain Nosler Accubond bullet at 3,380 fps muzzle velocity. This bullet has a B. C. of .414, which is not horrible, so it can work pretty well for long-range work. The next load has a 225-grain Barnes TSX bullet with a muzzle velocity of 3,180 and a B.C. of .482. The final load is a 250-grain Nosler Partition bullet at 3,060 fps with a B.C. of .482. I was only able to test the first two in my rifle as the Partition load was out of stock. The accuracy for five-shot groups was a little disappointing, but I suspect it\u2019s ammo more than the rifle. To make this rifle perform for long-range work, both in accuracy and in exterior ballistics, is going to require handloading. But, then again, anybody serious about precision shooting is likely going to handload. My guess is the 250-grain and 300-grain bullets that are offered will really make this gun step up and shine. The 250-grain can be driven to 3,072 fps according to Hodgdon. The 300-grain Sierra will exit at 2,818 and is an even better performer at ultra-long range than the 250-grain, due to the ultra-high ballistic coefficient.\n\nIf you want the biggest, baddest, 33-caliber long-range commercial cartridge on the planet and you don\u2019t mind working a bit to build the ammo, check out this new Weatherby TRR. It can blow the socks off anything else at ultra-long range.

Precision shooting continues to drive cartridge development across a wide spectrum. As those skillsets grow, so too does the proliferation in long-range hunting pursuits. Stated plainly: more folks want to shoot game a longer distances than seemingly ever before. Now that style of hunting brings its detractors to be sure. But hunting, especially out West, brings its own challenges. For those required or interested in going long, cartridge development remains a hot topic. <\/p>\n\n\n\n

Weatherby knows how to put performance into rifle cartridges. When the Weatherby name gets stamped on a casing, history says it brings a ton of performance. We expect nothing less from the new .338 WBY RPM.<\/p>\n\n\n\n

Looking to try something a little different for your next hunting trip? The Big Horn Armory AR500 Starter Kit packages serious big-bore power, putting everything you need into one convenient bundle. The package includes a Big Horn Armory AR chambered in 500 Auto Max and 100 rounds of ammunition. <\/p>\n\n\n\n\n\n

Big Horn Armory AR500 Starter Kit<\/h2>\n\n\n\n

First off, the package brings a serious ammo discount right out of the gate. With prices often topping $4.50 per round, the AR500 Starter Kit puts the 500 Auto Max at $2 per round. Buffalo Bore, Steinel Ammunition and Underwood Ammunition all provide factory loads for the 500 Auto Max.<\/p>\n\n\n\n

Better still, the package includes the BHA AR500 rifle<\/a>. Chambered in 500 Auto Max, this modern sporting rifle brings serious thump. For AR users, within that familiar manual of arms, shooters get uncommon knockdown power in a short- to medium-range cartridge. Big Horn Armory even offers a braced-pistol variant if you seek a compact field gun. <\/p>\n\n\n\n

Big Horn Armory cautioned this one will only be available for a limited time. For more info, call 307-586-3700 or visit bighornarmory.com.<\/a> <\/p>\n\n\n\n

Editor's Take: <\/h4>\n\n\n\n

The 500 Auto Max comprises a rimless 500 S&W. Magnum. Available factory ammo features bullet weights ranging from 350 to 600 grains. Handloaders get to work from 275 all the way up to a massive 700 grains. So this means you can really dial in on working up the right load to the particular application. Bullets also come in hard cast, jacketed hollow points and even monolithic solids. So there's a lot a good gun geek can really hone in on here in terms of performance. <\/p>\n\n\n\n

\"Fired<\/figure>\n\n\n\n

But we can geek out even more. The 500 Auto Max, according to data provided by Big Horn Armory, pushed a 400-grain bullet to a 2,275 fps muzzle velocity out of an 18-inch barrel in the BHA AR500. That outperforms well-known thumpers like the .45-70 and .450 Marlin with comparable bullet weights. <\/p>\n","post_title":"Big Horn Armory's AR500 Starter Kit Brings Big-Bore Hunting Power","post_excerpt":"","post_status":"publish","comment_status":"open","ping_status":"open","post_password":"","post_name":"bha-ar500-starter-kit","to_ping":"","pinged":"","post_modified":"2023-05-31 10:13:34","post_modified_gmt":"2023-05-31 10:13:34","post_content_filtered":"","post_parent":0,"guid":"https:\/\/www.athlonoutdoors.com\/2022\/04\/21\/bha-ar500-starter-kit\/","menu_order":0,"post_type":"post","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":157150,"post_author":"284","post_date":"2013-01-01 13:51:54","post_date_gmt":"2013-01-01 19:51:54","post_content":"It's not a big .50 BMG, but the Weatherby Mark V TRR and their .338-378 load can blow the socks off anything else at ultra-long range<\/em>\n\nRifle shooting seems to go in phases in America, and right now it\u2019s long-range shooting\u2019s time to shine.

The only requirement is simply that the rifle delivers a bullet to the target. If there is a cartridge that gets it there faster and hits the target harder, then where is the downside?\n\nThe .338-378 Weatherby cartridge uses the .378 Weatherby case, necked down to take a .338 bullet. That means it is a whopping big cartridge case. The .338-378 Weatherby case holds 137 grains of water compared to the .338 Lapua, which holds 114 grains of water. That\u2019s about a 20 percent increase in case capacity. More capacity means more propellant and more propellant means higher muzzle velocity. While the laws of diminishing returns start to apply with this big case, it still can push the same bullet substantially faster than the Lapua.

Another big issue at ultra-long range, one that is often not considered by most shooters, is retained energy. All cartridges are dropping to low energy levels at 1,500 yards. For example, the .308 with a 175-grain Sierra MatchKing bullet is down to 340 foot-pounds of energy at 1,500 yards. That\u2019s about the same as a 9mm pistol at the muzzle.\n\n\"d14168_phatch\"<\/a>\n\nThe .338 Lapua has 763 foot-pounds of retained energy at 1,500 yards while the .338-378 has 831 foot-pounds.

But that\u2019s changed.\n\nThreat Response .338-378<\/strong>\n\nWeatherby has entered into the long-range tactical rifle market recently with their Range Certified, Mark V Threat Response Rifle. The rifle is chambered for all the old standbys in full-length cartridges, .300 Winchester, .300 Weatherby and .30-378 Weatherby. That last cartridge can do for the 30-calibers what the .338-378 does for the 33s\u2014push any given bullet weight out the muzzle faster than any other 30-caliber cartridge. The rifle is, of course, offered in .338-378 Weatherby and, new for 2012, the .338 Lapua.\n\nThe rifle features a Krieger barrel with cut rifling. It\u2019s a #3 contour 26-inch fluted barrel with a big muzzle brake fitted on the end that has five slots on each side. The twist rate is 1:10, so the rifle can use bullets weighing 300 grains. The barrel is fully free-floated clear back to the action.\n\nThe camo stock has a flat-bottom forend to sit well in sandbags, as well as a metal slot for a swivel stud to attach a bi-pod. This slot allows 9 inches of adjustment for the stud placement. The stock has an adjustable comb that is locked securely in place with two Allen head screws. The stock is adjustable for length of pull with removable spacers from 13.25 inches to 14.75 inches. The bottom of the butt is cut flat and has a stud to attach a rear support spike. The pistol grip is large and drops almost straight down to position the hand behind the trigger.\n\nThe bolt has an extended oversize knob. The push feed bolt has a spring-loaded plunger in the face for an ejector and a pivoting, spring loaded extractor fitted to the bolt.\n\nThe bolt is classic Weatherby Mark V with nine locking lugs.

It\u2019s available in three configurations; a 200-grain Nosler Accubond bullet at 3,380 fps muzzle velocity. This bullet has a B. C. of .414, which is not horrible, so it can work pretty well for long-range work. The next load has a 225-grain Barnes TSX bullet with a muzzle velocity of 3,180 and a B.C. of .482. The final load is a 250-grain Nosler Partition bullet at 3,060 fps with a B.C. of .482. I was only able to test the first two in my rifle as the Partition load was out of stock. The accuracy for five-shot groups was a little disappointing, but I suspect it\u2019s ammo more than the rifle. To make this rifle perform for long-range work, both in accuracy and in exterior ballistics, is going to require handloading. But, then again, anybody serious about precision shooting is likely going to handload. My guess is the 250-grain and 300-grain bullets that are offered will really make this gun step up and shine. The 250-grain can be driven to 3,072 fps according to Hodgdon. The 300-grain Sierra will exit at 2,818 and is an even better performer at ultra-long range than the 250-grain, due to the ultra-high ballistic coefficient.\n\nIf you want the biggest, baddest, 33-caliber long-range commercial cartridge on the planet and you don\u2019t mind working a bit to build the ammo, check out this new Weatherby TRR.

Editor's Take<\/h4>\n\n\n\n

Precision shooting continues to drive cartridge development across a wide spectrum. As those skillsets grow, so too does the proliferation in long-range hunting pursuits. Stated plainly: more folks want to shoot game a longer distances than seemingly ever before. Now that style of hunting brings its detractors to be sure. But hunting, especially out West, brings its own challenges. For those required or interested in going long, cartridge development remains a hot topic. <\/p>\n\n\n\n

Weatherby knows how to put performance into rifle cartridges. When the Weatherby name gets stamped on a casing, history says it brings a ton of performance. We expect nothing less from the new .338 WBY RPM.<\/p>\n\n\n\n

Looking to try something a little different for your next hunting trip? The Big Horn Armory AR500 Starter Kit packages serious big-bore power, putting everything you need into one convenient bundle. The package includes a Big Horn Armory AR chambered in 500 Auto Max and 100 rounds of ammunition. <\/p>\n\n\n\n\n\n

Big Horn Armory AR500 Starter Kit<\/h2>\n\n\n\n

First off, the package brings a serious ammo discount right out of the gate. With prices often topping $4.50 per round, the AR500 Starter Kit puts the 500 Auto Max at $2 per round. Buffalo Bore, Steinel Ammunition and Underwood Ammunition all provide factory loads for the 500 Auto Max.<\/p>\n\n\n\n

Better still, the package includes the BHA AR500 rifle<\/a>. Chambered in 500 Auto Max, this modern sporting rifle brings serious thump. For AR users, within that familiar manual of arms, shooters get uncommon knockdown power in a short- to medium-range cartridge. Big Horn Armory even offers a braced-pistol variant if you seek a compact field gun. <\/p>\n\n\n\n

Big Horn Armory cautioned this one will only be available for a limited time. For more info, call 307-586-3700 or visit bighornarmory.com.<\/a> <\/p>\n\n\n\n

Editor's Take: <\/h4>\n\n\n\n

The 500 Auto Max comprises a rimless 500 S&W. Magnum. Available factory ammo features bullet weights ranging from 350 to 600 grains. Handloaders get to work from 275 all the way up to a massive 700 grains. So this means you can really dial in on working up the right load to the particular application. Bullets also come in hard cast, jacketed hollow points and even monolithic solids. So there's a lot a good gun geek can really hone in on here in terms of performance. <\/p>\n\n\n\n

\"Fired<\/figure>\n\n\n\n

But we can geek out even more. The 500 Auto Max, according to data provided by Big Horn Armory, pushed a 400-grain bullet to a 2,275 fps muzzle velocity out of an 18-inch barrel in the BHA AR500. That outperforms well-known thumpers like the .45-70 and .450 Marlin with comparable bullet weights. <\/p>\n","post_title":"Big Horn Armory's AR500 Starter Kit Brings Big-Bore Hunting Power","post_excerpt":"","post_status":"publish","comment_status":"open","ping_status":"open","post_password":"","post_name":"bha-ar500-starter-kit","to_ping":"","pinged":"","post_modified":"2023-05-31 10:13:34","post_modified_gmt":"2023-05-31 10:13:34","post_content_filtered":"","post_parent":0,"guid":"https:\/\/www.athlonoutdoors.com\/2022\/04\/21\/bha-ar500-starter-kit\/","menu_order":0,"post_type":"post","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":157150,"post_author":"284","post_date":"2013-01-01 13:51:54","post_date_gmt":"2013-01-01 19:51:54","post_content":"It's not a big .50 BMG, but the Weatherby Mark V TRR and their .338-378 load can blow the socks off anything else at ultra-long range<\/em>\n\nRifle shooting seems to go in phases in America, and right now it\u2019s long-range shooting\u2019s time to shine. American shooters are fascinated with the concept of reaching out and smacking targets so far away that they clang with a different accent.\n\nIt wasn\u2019t so long ago that we thought 500 yards was \u201clong range.\u201d Then 1,000 yards became the new normal. Now it starts getting interesting for a lot of shooters at 1,500 yards.\n\nIn recent years the .338 Lapua has emerged as the premier long-range sniper rifle cartridge. That\u2019s because for shooting at ultra-long range, 1,000 yards and beyond, many believe it\u2019s the cartridge that best achieves balance.\n\n\"d15236_phatch\"<\/a>\nWeatherby Mark V Sub-MOA Threat Response rifle features an oversize bolt handle for ease of operation<\/em>\n\nThe .50 BMG is not much fun to shoot for extended periods of time with all the blast and recoil. I have seen the muzzle brake on a fifty clear a shooting bench, even send a chronograph flying. Once I witnessed ammo boxes being blown off the bench along with a bag of potato chips turned into airborne confetti. That kind of blast level can wear on a shooter after multiple shots.\n\nOn the other end of the sniper cartridge spectrum is the .308 Winchester, which is running out of steam at 1,000 yards and is completely outclassed at 1,500 yards. The Lapua splits the difference and has proven that a big, heavy, high B.C. bullet is the key. Most .338 Lapua rifles weigh less than 20 pounds so they are easily transported. With that weight class and a good muzzle brake, the .338 Lapua is easy on the shooter with mild recoil and muzzle blast.\n\nThe .338 Lapua owes its success to two things: first it\u2019s a good cartridge, but perhaps even more important, it\u2019s had great marketing. Of course it doesn\u2019t hurt that the .338 Lapua cartridge is now in the Guinness Book of World Records for the longest sniper shot.\n\nA British sniper named Craig Harrison fired three shots with his Accuracy International .338 Lapua rifle during an altercation in the sandbox. The first round hit a bad guy running a machine gun and killed him. Another insurgent stepped up to the machine gun and a second bullet killed him. The third shot took out the machine gun. The distance was measured by GPS at 2,707 yards or 1.54 miles. That\u2019s long enough that, according to my ballistic program, it took the bullets more than five seconds to get there.\n\nMilitary Roots<\/strong>\n\nThe main reason that the .338 Lapua has become so popular is because the military is using it for long-range work. Selection by the military will all but guarantee the popularity of any cartridge. Note the four most popular sniper rifle cartridges, the .308, .300 Win, .338 Lapua and the .50 BMG. They are all popular because the military uses them. But other than the .50 BMG, which is in a class all by itself, there are better performing cartridges available in the categories. They fail to achieve the degree of success, not because of any technical reason, but because of the military connection. But civilians are not bound by military selection and we can pick the cartridge that works best, not the one that some politicized General says we must use.\n\nThe .338 Lapua was developed with the 250-grain bullet in mind. Lately there is a move to 300-grain bullets, but at least for now the 250-grain is still the cartridge standard. Federal\u2019s most popular .338 Lapua load uses a 250-grain MatchKing bullet with a peak B.C. of 0.606 and a M.V. of 2,950 fps. While that\u2019s a respectable muzzle velocity, there is at least one commercial cartridge capable of driving the same bullet even faster, the .338-378 Weatherby.\n\nWeatherby\u2019s .338<\/strong>\n\n\"d14080_phatch\"<\/a>\nThe .338-378 uses the .378 Weatherby case necked down to take a .338 bullet, resulting in a sizeable cartridge with a 20-percent increase in case capacity<\/em>\n\nLike all the Weatherby rifle cartridges, the .338-378 was developed for hunting. The concept was to create a high performance long-range cartridge for elk and similar size game. But, long range shooting is long range shooting regardless if the target is an elk or a steel gong. The only requirement is simply that the rifle delivers a bullet to the target. If there is a cartridge that gets it there faster and hits the target harder, then where is the downside?\n\nThe .338-378 Weatherby cartridge uses the .378 Weatherby case, necked down to take a .338 bullet. That means it is a whopping big cartridge case. The .338-378 Weatherby case holds 137 grains of water compared to the .338 Lapua, which holds 114 grains of water. That\u2019s about a 20 percent increase in case capacity. More capacity means more propellant and more propellant means higher muzzle velocity. While the laws of diminishing returns start to apply with this big case, it still can push the same bullet substantially faster than the Lapua. That means the bullet gets to the target faster, retains more energy and has a flatter trajectory curve.\n\nWeatherby lists the muzzle velocity of their 250-grain Nosler Partition load at 3,060 fps. Hodgdon\u2019s online handloading data lists the .338-378 Weatherby with a 250-grain bullet with a statistically identical muzzle velocity of 3,072 fps. That\u2019s faster than anything else that is pushing the same diameter and weight bullet.\n\nUsing a 250-yard zero, by the time the bullet is at 1,500 yards that little bit of extra velocity has the point of impact for the .338-378 at 73.19 inches higher than the .338 Lapua. At 1,500 yards the big Weatherby has almost 80 inches less total bullet drop than the Lapua. Another big issue at ultra-long range, one that is often not considered by most shooters, is retained energy. All cartridges are dropping to low energy levels at 1,500 yards. For example, the .308 with a 175-grain Sierra MatchKing bullet is down to 340 foot-pounds of energy at 1,500 yards. That\u2019s about the same as a 9mm pistol at the muzzle.\n\n\"d14168_phatch\"<\/a>\n\nThe .338 Lapua has 763 foot-pounds of retained energy at 1,500 yards while the .338-378 has 831 foot-pounds. That\u2019s nearly a 10% increase and at that distance every foot-pound counts.\n\nThere is no question that assuming equal accuracy, the .338-378 Weatherby deserves consideration by the long-range shooting crowd and that it can surpass the performance of their current darling, the .338 Lapua.\n\nThe problem was that until now you could only find the .338-378 in a hunting style rifle. If you wanted it in a tactical, long-range configuration you had to have it custom built. But that\u2019s changed.\n\nThreat Response .338-378<\/strong>\n\nWeatherby has entered into the long-range tactical rifle market recently with their Range Certified, Mark V Threat Response Rifle. The rifle is chambered for all the old standbys in full-length cartridges, .300 Winchester, .300 Weatherby and .30-378 Weatherby. That last cartridge can do for the 30-calibers what the .338-378 does for the 33s\u2014push any given bullet weight out the muzzle faster than any other 30-caliber cartridge. The rifle is, of course, offered in .338-378 Weatherby and, new for 2012, the .338 Lapua.\n\nThe rifle features a Krieger barrel with cut rifling. It\u2019s a #3 contour 26-inch fluted barrel with a big muzzle brake fitted on the end that has five slots on each side. The twist rate is 1:10, so the rifle can use bullets weighing 300 grains. The barrel is fully free-floated clear back to the action.\n\nThe camo stock has a flat-bottom forend to sit well in sandbags, as well as a metal slot for a swivel stud to attach a bi-pod. This slot allows 9 inches of adjustment for the stud placement. The stock has an adjustable comb that is locked securely in place with two Allen head screws. The stock is adjustable for length of pull with removable spacers from 13.25 inches to 14.75 inches. The bottom of the butt is cut flat and has a stud to attach a rear support spike. The pistol grip is large and drops almost straight down to position the hand behind the trigger.\n\nThe bolt has an extended oversize knob. The push feed bolt has a spring-loaded plunger in the face for an ejector and a pivoting, spring loaded extractor fitted to the bolt.\n\nThe bolt is classic Weatherby Mark V with nine locking lugs. This means a shorter 54-degree rotation to open the bolt, which makes it faster to operate. The Mark V uses a full-size, fluted bolt body running inside the tubular action. There is no binding and it runs smooth. The bolt head is actually smaller than the bolt body. According to a Weatherby representative, that is why they do not use a removable box magazine.\n\n\"d15244_phatch\"<\/a>\n\nNot having a removable box magazine is one of the few criticisms I have of the rifle. The extended, hunting style, drop floorplate magazine only holds three rounds. It\u2019s also a bit slow to reload as the loaded cartridges are longer than the loading port, so they must be put in point first and then moved back to position as they are pushed down into the magazine.\n\nThere is a large two-position safety on the right side of the action. It rotates forward for fire and back for safe. The trigger on my sample breaks cleanly at 3 pounds, 3 ounces.\n\nI ordered a rail style scope mount from Evolution Gun Works, Inc. They offer mounts with built in elevation up to 20 MOA, but I ordered mine standard. I fitted the gun with a Swarovski 6-24x50 scope (swarovskioptik.us). The clear optics and reliable repeatability of the adjustments make this a good choice for this rifle.\n\n\"d15246_phatch\"<\/a>\nThe Weatherby .338-378 was developed to create a high-performance cartridge for hunting monster bull elk and similar big-game species at long range<\/em>\n\nFeeding The Beast<\/strong>\n\nThe other downside of this cartridge for long-range shooting is that ammo is only available from Weatherby and so far they only make hunting style ammo. It\u2019s available in three configurations; a 200-grain Nosler Accubond bullet at 3,380 fps muzzle velocity. This bullet has a B. C. of .414, which is not horrible, so it can work pretty well for long-range work. The next load has a 225-grain Barnes TSX bullet with a muzzle velocity of 3,180 and a B.C. of .482. The final load is a 250-grain Nosler Partition bullet at 3,060 fps with a B.C. of .482. I was only able to test the first two in my rifle as the Partition load was out of stock. The accuracy for five-shot groups was a little disappointing, but I suspect it\u2019s ammo more than the rifle. To make this rifle perform for long-range work, both in accuracy and in exterior ballistics, is going to require handloading. But, then again, anybody serious about precision shooting is likely going to handload. My guess is the 250-grain and 300-grain bullets that are offered will really make this gun step up and shine. The 250-grain can be driven to 3,072 fps according to Hodgdon. The 300-grain Sierra will exit at 2,818 and is an even better performer at ultra-long range than the 250-grain, due to the ultra-high ballistic coefficient.\n\nIf you want the biggest, baddest, 33-caliber long-range commercial cartridge on the planet and you don\u2019t mind working a bit to build the ammo, check out this new Weatherby TRR.
