About Winchester
Winchester Ammunition is manufactured by Olin Corporation at their plant in Oxford, Mississippi. The Winchester brand dates to 1866 — one of the oldest names in American firearms and ammunition. Winchester produces a full range of handgun, rifle, rimfire, and shotshell ammunition. The "White Box" USA line is one of the most recognized range ammo brands in America, available at nearly every retailer from Walmart to specialty online shops.
