Winchester has a history of making high quality ammunition for more than 125 years. In 1873, 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. For hunters and sportsmen wanting the ultimate ammunition for any big-game need, Winchester has been delivering ever since. Winchester Ammunition's innovations and benchmarks of quality and performance have established themselves as "What America Shoots!" Furthermore, Winchester has produced billions of rounds of small-arms ammo over the past century, supplying the United States military and its allies.
