Georgia-based ammo maker G2 Research has announced that it’s new 12-gauge R.I.P. self-defense round will be available this fall.

In development for over three years, this 0.725-inch diameter 303 grain all-brass precision CNC machined slug uses the company’s R.I.P. technology, which releases six trocars (metal petals) into the target for “instant devastation,” the press release says.

Upon reaching a target, the six trocars open, detach and spread through the target six-inches wide, delivering nine to 11 inches of penetration. The slug’s .70 caliber base continues forward for another five to six inches.

The true effective performance expansion range for the round ranges from zero to 10 yards. Beyond that range, slug will begin to yaw, which could potentially affect the correct strike angle for it to open as designed, G2 says.

Boasting an average velocity of 1430 FPS–depending on the barrel length—this new round isn’t meant to be fired in guns with rifling, compensators, chokes or modified barrel cylinders. The only type of barrel it can be safely used in is a smooth bore riot type shotgun barrel.

G2 Research also says the round isn’t designed for hunting, sporting, or barrier penetration. Self defense is the name of the game here.

“This 12 gauge round is very specific in its design and mission; that of a person defending his life and/or that of his family. The real question is how much value we put on put on our own life or that of those we are protecting,” G2 marketing director Mike Nickerson said in a statement.

The MSRP for five rounds will be $49.99.
