Winchester USA Features The Winchester Lake City .223 Rem load pairs a 55 grain full metal jacket bullet with a reloadable boxer-primed brass case giving shooters a round built for both immediate use and future reloading. At 3240 feet per second and 1282 foot-pounds of energy this load delivers the flat trajectory and reliable function that AR-platform rifles are built around. Lake City ammunition carries a long-standing reputation built on decades of producing military and commercial rifle ammunition to consistent specifications. Shooters running high-volume training or competition practice benefit from that manufacturing consistency across every round in the case. Because the brass is both reloadable and boxer-primed handloaders who shoot through large volumes of this ammunition can recover and reload spent cases rather than discarding them after a single firing. The ammunition is manufactured in the U.S.A. reflecting Lake City s domestic production standards that many shooters specifically seek out for their .223 Rem training ammo. This load is sold as a case giving shooters a large supply ready for extended range sessions without needing to restock mid-way through a training day. The Winchester Lake City .223 Rem 55 grain FMJ is a dependable choice for AR shooters who put significant volume through their rifles on a regular basis.
