The Winchester USA Rifle Ammo 223 Rem. 55 gr. FMJ 200 rd. brings reliable performance for target shooters and range professionals who demand consistency, with Lake City Manufactured Ammunition pedigree that underscores its trusted lineage and American origin. This 223 Remington load uses a 55 grain full metal jacket bullet seated in brass casings, delivering a flat-shooting trajectory and dependable cycling in semi-automatic and bolt-action rifles, and its 3240 fps muzzle velocity and 1282 ft?lbs of energy provide the ballistics needed for accurate zeroing and long strings on steel or paper at the range. As an economical bulk option for high-volume practice, it feeds smoothly, maintains tight groupings at common engagement distances, and is suited for drills, competition practice, and establishing consistent cheek weld and trigger control. The FMJ profile reduces barrel fouling and offers predictable impacts for scoring and training, while the U.S. origin and ORM-D/HazAir marking make logistics straightforward for range operators. If you run a busy range or log a lot of training hours, this Winchester Lake City series gives the consistent ammunition performance that keeps shooters on target.
