SinterFire Rifle Ammunition Features The SinterFire Reduced Hazard Ammo line is built around a lead free frangible bullet in .223 Rem engineered to break into fine particles on impact with hard targets rather than ricocheting. This frangible construction makes it a popular choice for close quarters training steel target work and indoor ranges where standard jacketed bullets would pose an unacceptable ricochet risk. At 55 grains the projectile matches common .223 Rem training loads so shooters see comparable recoil and trajectory while gaining the added safety margin. The brass casing supports consistent reliable function across a range of semi auto and bolt action rifles chambered in the cartridge. Each box contains 50 rounds giving shooters and training facilities a practical quantity for range sessions or qualification courses. Because the bullet material breaks down on impact rather than penetrating or deflecting it reduces the hazard footprint around steel targets and barriers compared to conventional ammunition. This makes SinterFire Reduced Hazard Ammo well suited to tactical training environments military and law enforcement qualification and civilian ranges with strict safety requirements. For shooters and facilities that need dependable .223 Rem performance with reduced ricochet risk SinterFire Reduced Hazard Ammo is available for sale at GrabAGun.
