Winchester Centerfire Rifle Bullets 5.56 NATO .224" 55 gr FMJ 100/ct

Winchester Centerfire Rifle Bullets 5.56 NATO .224" 55 gr FMJ deliver proven performance for high-volume reloading operations and precision rifle training. These full metal jacket boat tail projectiles are engineered for consistent ballistics across tactical and competition shooting applications, offering the reliability and accuracy that operators and serious reloaders expect from Winchester bulk components.

Each 100-count box contains .224-inch diameter, 55-grain bullets featuring a lead core wrapped in copper jacket construction. The boat tail geometry reduces drag and improves stability at distance, while the full metal jacket design minimizes fouling and extends barrel life compared to hollow point or soft point alternatives. At 55 grains, this weight class optimizes velocity from intermediate-length barrels while maintaining the supersonic threshold critical for 5.56 NATO performance. Reloaders benefit from consistent cartridge specifications and predictable pressure curves when using these components with appropriate powders and primers.

These bullets suit law enforcement training programs, military marksmanship courses, competitive rifle matches, and dedicated handloaders seeking bulk quantities without compromise on quality control. The 100-round box format provides flexibility for midrange reloading sessions while maintaining the cost efficiency that bulk components are known for. Whether zeroing duty rifles, conducting qualification exercises, or refining reloads for precision work, the Winchester 55 gr FMJ delivers repeatable downrange performance across diverse shooting disciplines.

5.56 NATO ammunition components have become the standard platform for military, law enforcement, and civilian tactical training worldwide. Winchester's centerfire bullet line maintains strict manufacturing tolerances to ensure uniform seating, flight characteristics, and impact behavior—factors that directly affect group consistency and user confidence in reloaded ammunition.
