Frontier Cartridge Military Grade 223 Remington ammunition delivers reliable, American-made rounds built on decades of ammunition engineering. These 55-grain full metal jacket boat-tail cartridges pair Hornady's reputation for consistency with military-grade components—boxer primers, quality brass cases, and proven propellant—so you get dependable performance whether you're running drills at the range, zeroing hunting rifles, or training for duty. Every round is loaded to exacting standards, so you're not gambling on quality from round to round.

The 55-grain FMJ-BT bullet design offers the accuracy potential of a boat-tail profile with the straightforward reliability of a full metal jacket. That combination makes these rounds at home in AR-15s, bolt guns, and service rifles alike. Hornady's non-steel core bullets feed smoothly and won't damage backstops or range berms the way some surplus or imported ammunition can. If you're shooting on a budget without cutting corners on consistency, Frontier Cartridge ammunition is engineered to perform.

Built for shooters who demand American manufacturing and military-grade construction, this ammunition is suitable for a wide range of applications—from high-volume range sessions to varmint work on small game. The brass cases and reliable primers mean you can reload if you choose, extending the value of every shot. Frontier Cartridge proves you don't have to compromise on quality to get honest, affordable ammunition that works, shot after shot.
