Winchester Ammunition USA 5.56x45mm NATO 55gr FMJ - 1000 Rd Case

The Winchester USA 5.56x45mm NATO line delivers reliable, American-made ammunition for high-volume range sessions and tactical training. This 1000-round case of 55gr Full Metal Jacket ammo is loaded to the military's M193 specification, pairing a 55-grain lead-core FMJ projectile with a reloadable case for consistent feeding and trouble-free function in AR-pattern rifles and other 5.56 NATO chambers.

Built around Winchester's value-priced USA White Box platform, this 5.56x45mm load is a go-to choice for AR-15 owners stocking up for practice, drills, and training days. The full metal jacket bullet promotes smooth feeding from standard magazines, while the M193-spec loading delivers the familiar ballistics and felt recoil shooters expect from service-rifle ammunition.

Supplied as a single bulk-packed 1000-round case with 1000 cartridges per box and 1 box per case, this reloadable USA load is ideal for range stockpiles, classes, and any high-volume shooter who wants Winchester quality at a case-lot price.
