Winchester's Super-X Proven Performance line of Supreme ammunition offers inexpensive, high quality, and proven performance cartridges for all purposes.

Winchester Supreme Centerfire Rifle Ammunition stands as the most technologically advanced line of centerfire rifle ammunition in history - a history 127 years in the making. In 1873, less than a decade after the Civil War and when Westward expansion was in full gallop, Winchester introduced the first successful centerfire cartridge: the .44 WCF (.44-40). Designed for double duty in both rifles and handguns, this is the cartridge that won the west. And to hunters and sportsmen wanting the ultimate ammunition for any big-game need, Winchester has been delivering ever since.
