Frontier 223rem 55gr Fmj 20/500

Frontier 223 Remington 55gr full metal jacket ammunition delivers the ballistic consistency and dependable performance required for high-volume training, marksmanship development, and range-intensive operations. Loaded with Hornady bullets and optimized for 3,240 feet per second velocity, this cartridge is engineered for practitioners who demand consistency across hundreds of rounds without premium pricing.

The 55-grain full metal jacket configuration balances velocity, trajectory stability, and barrier penetration across typical engagement distances. At 3,240 fps, this round maintains supersonic velocity throughout most practical shooting ranges, critical for consistent bullet performance and sound signature in training environments. The full metal jacket design minimizes lead exposure during high-round-count sessions and reduces fouling in semi-automatic platforms, extending maintenance intervals on duty and training weapons. Each box contains 20 rounds, enabling efficient lot-numbering and ammunition management in regulated or accountability-sensitive environments.

Law enforcement agencies, military training units, and serious civilian shooters select Frontier 223 Remington for qualification cycles, low-light drills, force-on-force scenarios, and extended marksmanship courses where ammunition cost-per-round directly impacts training frequency. The Hornady manufacturing standard ensures chamber-fit reliability across AR-15 and other 223 Remington platforms, minimizing chambering inconsistencies that compromise grouping. For shooters prioritizing training volume without sacrificing ballistic predictability, this round delivers measurable value in high-round-count applications.
