For serious shooters, Winchester USA Ammunition is the ideal choice for training, competition or a long session at the range. The easily identifiable white box means high quality and reliability at a low price. This ammunition is loaded with a full metal jacket bullet which is known for its positive functioning and exceptional accuracy. On impact this bullet does not expand and is ideal for target shooting. This ammunition is new production, non-corrosive, in boxer primed, reloadable brass cases.

Please Note: While the 5.56x45mm will fit in a .223 Remington chamber, the 5.56 is a military round that runs at higher pressures than its .223 counterpart and is not recommended to be fired in a .223 Remington Chamber.
