Winchester‘s Lake City M193 loading in 5.56mm NATO (brand part no. WM193300C) loads a 55-grain full metal jacket bullet at a listed 3,270 feet per second, packed 300 rounds to a reusable polymer ammo can. M193 is the original military specification loading for 5.56mm, and Lake City is the U.S. Army ammunition plant whose brass and loadings set the standard other manufacturers are measured against. The reloadable brass case is boxer-primed and non-corrosive, and Winchester lists muzzle energy at 1,306 foot-pounds, real numbers behind a genuinely mil-spec round rather than a commercial approximation. For 5.56mm and .223 Remington shooters who want authentic M193 ballistics in bulk, this rifle ammunition delivers it.
