The Winchester USA .223 Remington ammunition features a 55 grain, full metal jacket projectile capable of traveling 3240 feet per second giving it 1282 foot pounds of muzzle energy designed for target shooting, plinking and training. This load features non-corrosive, reloadable brass casing to improve feed reliability and prevent damage to the firearm's chamber. The full metal jacket consists of a soft core, encased in a harder metal shell to maintain their composure and trajectory for greater penetration and less expansion.
