Win 223rem 55gr Fmj 200/800

Winchester Ammunition 223 Remington 55gr Full Metal Jacket ammunition delivers consistent, reliable performance for training, tactical operations, and general rifle shooting. Packaged in 200-round boxes with 800 rounds per case, this Lake City-produced cartridge provides shooters with the volume and economy necessary for high-round-count training cycles and duty use without compromising on Winchester's established quality standards.

The 55-grain Full Metal Jacket projectile is the ballistic standard for 223 Remington rifle applications. This bullet weight offers flat trajectory and moderate velocity suitable for AR-platform rifles and bolt-action .223 rifles across typical engagement distances. The FMJ construction provides hard-target penetration and consistent performance through intermediate barriers, making this load appropriate for barrier-blind shooting scenarios where hollow-point expansion is not the priority. Winchester's Lake City manufacturing ensures tight quality control over primer ignition, powder charge, and bullet seating—critical factors for shooters who demand shot-to-shot consistency during qualification courses or extended range sessions.

This ammunition serves law enforcement and military personnel conducting qualification training, tactical units requiring high-volume practice loads, civilian shooters building rifle proficiency on the AR-15 platform, and range facilities stocking bulk ammunition for rental systems. The 800-round case format supports armory inventory management and reduces per-round cost for agencies and serious competitors running frequent live-fire drills. Full Metal Jacket construction is widely accepted at indoor ranges and does not rely on hollow-point expansion, making it compliant with ammunition restrictions in certain jurisdictions where FMJ duty loads are permitted.

Within the 223 Remington market, Winchester ammunition is recognized for consistent primer and powder loading. The 55-grain FMJ is the most common commercial load and serves as the baseline for rifle accuracy testing and velocity measurement. Shooters switching between different 223 platforms benefit from this bullet weight's broad compatibility and predictable ballistics across various rifle configurations.
