About This Winchester 5.56x45mm AmmunitionThis 5.56x45 cartridge from Winchester’s USA line of ammunition is made right here in America at the Lake City Army Ammunition Plant. Originally established by Remington Arms to supply ammo to the U.S. Army in 1940, this plant has remained open nearly continuously to this day and now produces over one billion rounds per year.
This bulk pack is brimming with 1,000 rounds, packaged loosely in order to save you money. These cartridges sport 55 grain projectiles, the full metal jackets of which assure that your rifle will stay accurate over the course of a long shooting session. Because their Boxer primers are non-corrosive your weapon’s bore and action will be relatively unaffected by harmful residue while firing these rounds, and because their factory fresh casings are made from brass you’ll be able to handload them a few times. Truly a great value, made even better by our free shipping!
