SinterFire Green Line Features The SinterFire Green Line load in .223 Rem uses a lead free frangible 55 grain projectile that is engineered to break apart into fine powder upon striking a hard surface which means dramatically reduced ricochet hazard on steel targets and indoor ranges. This frangible construction makes the round a strong choice for close-quarters training environments and shoot houses where standard jacketed bullets pose splashback risk. Because the bullet contains no lead core shooters and range operators benefit from lower airborne lead exposure during extended training sessions. The brass casing construction keeps the round compatible with standard .223 chambers and extraction systems. Each box delivers 50 rounds giving trainers and range facilities a dependable supply for repetitive drills without the cost premium of premium hunting ammunition. The frangible design still cycles reliably through semi-automatic rifles so shooters get realistic recoil and function without compromising safety on steel. This makes the SinterFire Green Line ideal for tactical training qualification courses and any range environment where ricochet control matters. The SinterFire Green Line .223 Rem load is available for sale at GrabAGun for shooters who need a safer training round without sacrificing reliability.
