Winchester USA white box ammo has been a range staple for generations, and the USA9W packs its 115 grain 9mm load into 200 round boxes for high-volume shooters. This listing is Winchester USA 9mm Luger 115 grain full metal jacket ammo, MPN USA9W, sold as a 1,000 round case.

The 115 grain FMJ bullet is the standard practice weight for 9mm. Winchester rates this load at 1,190 fps with 362 ft-lbs of muzzle energy, which gives it a lively feel and solid cycling in pistols with stiffer recoil springs. A full metal jacket bullet does not expand, so this ammunition is built for target practice, steel, competition, and training rather than self defense or hunting.

This ammunition fits any firearm chambered in 9mm Luger, also called 9x19mm or 9mm Parabellum, including the Glock 17, 19, 43X, and 48, the SIG Sauer P320 and P365, Smith and Wesson M&P9 and Shield, Springfield Hellcat and XD, Ruger Security-9, CZ P-10, and pistol caliber carbines such as the Ruger PC Carbine. A common question is how USA9W differs from other Winchester USA 9mm items. The load is the same 115 grain FMJ; the item numbers mostly reflect box size, and USA9W uses 200 round boxes so you spend less time opening packaging. Another common question is whether this ammo is reloadable. Yes. It uses brass cases with boxer primers. A third question is whether 9mm and 380 ACP are interchangeable. They are not, so only use this ammunition in a firearm marked 9mm Luger or 9×19.

Winchester USA9W is new production ammunition, not reloads, made in the USA. Each round uses a brass case with a boxer primer and is non-corrosive. This case comes in factory packaging as 5 boxes of 200 rounds for a total of 1,000 rounds of 9mm 115 grain FMJ. Buying by the case keeps you on one production lot so your pistol sees consistent ammunition from box to box.
