Ammunition
Winchester's success was founded on a cartridge, the .44 Henry rimfire, and the Henry and 1866 rifles designed for it. Winchester was a leading designer of rifle ammunition throughout its existence, and has been responsible for some of the most successful cartridges ever introduced, including the .44-40 WCF (Winchester Center Fire), the .30 WCF (.30-30), the .50 BMG, the .270 Winchester, the .308 Winchester, the .243 Winchester, the .22 WMR (.22 Magnum), and the .300 Winchester Magnum. In North America the .30-30 is the best-selling hunting cartridge in history; and the .308, the commercial version of the military 7.62x51mm NATO, is not far behind, and one of the most popular hunting cartridges in the world.
Olin Corporation continues to manufacture Winchester ammunition (the cartridge business was not sold to U.S. Repeating Arms) in several lines including Super-X, Supreme and Supreme Elite, AA and Super Target shotshells, and Winchester Cowboy Loads revolver cartridges.
