History: One of the less common Winchester Model 1886 cartridges, the .38-70 was available on special order for hunters who wanted a .38 caliber option in the Model 1886 action. It is a transitional black powder cartridge from the late 1880s, predating the adoption of smokeless powder in lever-action rifles.
