Remington UMC .223 Remington 55-grain Metal Case ammunition (brand part no. 23895) is bulk-packed rifle ammo built for shooters who burn through rounds fast at the range. Remington loads this UMC line specifically for high-volume practice, target shooting, and varmint control, using a Metal Case (MC) bullet that mirrors a full metal jacket profile for reliable feeding through semi-automatic .223 rifles. Rated at 3240 fps, the load runs flat and fast out of most AR-platform rifles and bolt-action .223s alike. Each case holds a full 1000 rounds, enough to cover a long weekend of drills, a match, or months of casual range trips without reordering. For anyone who shoots .223 Remington in volume, this bulk case keeps cost per trigger pull down without cutting corners on quality.
