Winchester USA 223 Remington 55 grain full metal jacket ammunition delivers reliable, affordable centerfire rifle rounds built for shooters who need dependable performance without the premium price tag. Whether you're training at the range, zeroing a new rifle, or running drills with your AR-15, this Lake City–manufactured ammo provides the consistency you'd expect from Winchester's USA line. The 55-grain full metal jacket bullet is a proven load for .223 rifles, offering straightforward ballistics and clean function across semi-automatic and bolt-action platforms alike.

Because this ammunition is military-grade surplus, you may notice surface discoloration on the cases—that's a normal result of the annealing process used during manufacturing and doesn't affect reliability or safety. Similarly, minor case blemishes can occur during bulk packing, but these cosmetic variations never compromise performance. If you're accustomed to pristine retail ammunition, the appearance may surprise you; the trade-off is genuine value for high-volume training and practice.

Winchester USA .223 ammunition is a go-to choice for AR-15 owners, competitive shooters, and hunters who want to keep costs down on practice and field rounds.
