Frontier .223 Remington 55gr FMJ Ammo 1,000 Rounds

Frontier .223 Remington 55gr FMJ Ammo delivers reliable, cost-effective training and practice ammunition for AR-15 platforms and .223 bolt-action rifles. Purpose-built for shooters who demand consistent performance without premium pricing, this load serves law enforcement trainers, military reserve units, and civilian marksmanship programs. The 55-grain full metal jacket projectile is optimized for mid-range ballistics and barrier penetration, making it suitable for qualification courses, range drills, and field exercises where volume matters.

Manufactured by Hornady, a brand with deep roots in law enforcement and military supply, each round features a copper-jacketed, lead-core projectile seated in brass casing with a consistent powder charge and reliable primer. The 55-grain bullet weight is the standard .223 military specification, delivering stable flight at typical combat distances (0–300 yards) with minimal wind drift compared to lighter varmint loads. Full metal jacket construction reduces fouling and splatter compared to soft-point rounds, extending barrel life and reducing cleaning time—critical factors in high-volume training environments.

This ammunition is compatible with all standard AR-15 rifles, M16 platforms, and any firearm chambered in .223 Remington or 5.56 NATO (though always verify your specific barrel marking). Shooters working through qualification courses, academy certifications, or transition training benefit from the predictable trajectory and reliable feeding in semi-automatic actions. Purchase by the box and manage inventory for team training cycles, individual skill sustainment, or range inventory stockpiling where cost per round is a controlling budget factor.
