SinterFire Reduced Hazard 223 Rem 55gr Frangible 50rd Box

SinterFire projectiles are pressed from a copper and tin composite and heat treated rather than cast from lead. Hit something harder than the bullet, like a steel plate or a concrete wall, and it powders instead of coming back at you. That is why shoot houses, tactical training facilities and close range steel drills run this ammunition instead of ball.

The 55gr load in 223 Rem is built on new brass cases and runs at normal carbine velocity, so it cycles an AR-15 the same way standard ammunition does. Losing the lead core also means far less airborne lead in an enclosed range, which matters if you shoot indoors regularly. Boxed 50rd.
