Winchester USA WM80 7.62x51 NATO 149gr FMJ – 500-Round Case

Stock up for range days with Winchester USA “White Box” WM80 7.62×51mm NATO ammunition in a bulk 500-round case. This load is the commercial Winchester USA M80-style ball round: a 149-grain full metal jacket (FMJ) bullet over modern, cleaner-burning propellant in brass cases. Winchester lists muzzle velocity at 2,790 fps and muzzle energy at 2,575 ft-lbs, with a published G1 ballistic coefficient of 0.456. Rounds are typically packed 20 per box (25 boxes per 500-round case), so you get a full training allotment in one purchase.

Winchester markets the USA line for target and range use. The FMJ bullet and brass case are designed to cycle reliably in a wide variety of 7.62×51 NATO rifles—platforms often associated with this cartridge include M1A/M14-pattern rifles, FAL, G3/HK91-style rifles, SCAR 17, and AR-10 / LR-308 pattern rifles. Always confirm your firearm’s chambering and the manufacturer’s guidance before firing 7.62×51 NATO ammunition; many .308 Winchester rifles can fire NATO loads, but you should verify with your rifle maker first.

Key published specifications (Winchester USA WM80): caliber 7.62×51mm NATO; bullet weight 149 grains; bullet type Full Metal Jacket; brand USA; symbol/SKU WM80; G1 BC 0.456; muzzle velocity 2,790 fps; muzzle energy 2,575 ft-lbs; rounds per box 20. Usage category on Winchester’s USA rifle chart: target / range. The full metal jacket design does not expand, which is why this load is intended for practice, steel, and high-volume training rather than hunting.

Buying a 500-round case lowers cost per round and keeps you from running out mid-season. Brass is reloadable for handloaders who want to reclaim cases after range sessions. Modern propellants in the USA line are described by Winchester as reducing barrel fouling compared with older surplus-style loads, so you spend more time shooting and less time scrubbing.
