SinterFire Rifle Ammunition Features The SinterFire load in .300 AAC Blackout uses a 110 grain lead free frangible bullet engineered to disintegrate into fine particles upon striking a hard target rather than deflecting or fragmenting into larger pieces. This behavior significantly reduces the risk of dangerous ricochet making the round a strong choice for close quarters training environments and steel target shooting where standard jacketed bullets pose a greater hazard. The lead free composition also minimizes airborne lead exposure a benefit for shooters who spend extended time at indoor or enclosed ranges. Despite its frangible nature the round still cycles reliably through semi auto .300 Blackout platforms. Each round is built on a reloadable brass casing offering handloaders the option to recover and reuse cases after a training session. Packed 50 rounds to a box this ammunition provides a solid supply for an extended range day focused on repetition and skill building. The frangible design makes this load particularly well suited for close range tactical training drills where standard ammunition would be restricted for safety reasons.
