Winchester Ammunition

The Winchester Repeating Arms Company was a prominent American maker of repeating firearms, located in New Haven, Connecticut. The Winchester brand is today owned by the Olin Corporation. 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.

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. In North America the .30-30 is the best-selling hunting cartridge in history; and the .308 Winchester, the commercial version of the military 7.62×51mm NATO, is not far behind, and one of the most popular hunting cartridges in the world.
