Winchester's 1873 rifle was the Rifle that Won the West. It was chambered in a new, more powerful cartridge, the .44-40a .44 caliber bullet, propelled by 40 grains of black powder. However, a factor that really insured the success of the 1873 Winchester rifles was that Colt quickly offered its Peacemaker chambered in .44-40, as well. A cowboy could have both a lever-action rifle and his six shooter, and needed only one cartridge belt for both. Most Texas Rangers and every old West cowboy worth his salt carried 1873 rifles. Chappo, the son of Apache war chief Geronimo, packed an 1873. And Buffalo Bill carried an 1873 lever-action rifle along with a pair of .44-40 Colts in 1876 when he worked as an Army scout. This piece of rifle history is available in a variety of distinctive models including the Carbine Sporting Rifle.
