You’ve got a Ruger-5.7, FN Five-seveN, AR-57, or some other firearm that runs on (regrettably scarce) 5.7x28mm ammunition. And now you’ve got a hot lead on a whole case of self-defense ammo that you can also burn through at the range!

This ammunition is loaded with 40 grain polymer tipped hollow point bullets. Their tips streamline the bullets so they can fly straighter, exhibit more consistent trajectories, and arrive at their target with more energy on impact. Their nose cavities equip the bullets for terminal expansion – aka the ballistics which neutralize a threat more effectively while simultaneously mitigating the risk of over-penetration.

This American-made ammo’s nonmagnetic tipped HP projectiles are seated in brand new brass cases. Fiocchi’s noncorrosive Boxer primers deliver the reliable sparks which set their clean-burning propellant into action. Order the whole case and you’ll finally have enough 5.7 to train with the same ammo you’d use to defend your life!
