This is Winchester’s USA ammo, an old stand by at ranges across the country and always made in America. Loaded to M193 specifications, this cartridge’s 55 grain bullet provides the 3,180 fps muzzle velocity your AR-15 needs to perform impressive feats of accuracy. As an FMJ the bullet enhances a semi-auto’s functionality by feeding without jamming and preventing accelerated lead fouling. (Just don’t expect terminal expansion.)

You won’t find any steel in this bullet’s jacket or core, so you’re clear to take this ammo to indoor ranges where magnetic rounds are banned. Winchester’s brass cases are also super reliable, drawn to precise dimensions to ensure even more reliable feeding and extraction. These military-grade brass cases have been heat-treated to prevent them from splitting at the neck during ignition. They weren’t subsequently polished, so they still have cosmetic discoloration.
