The .25-35 Winchester Center Fire was introduced in 1895 by Winchester for the Winchester Model 1894. Together with the .30-30 Winchester, it was one of the earliest smokeless cartridges designed in North America for a sporting rifle.^[2] Savage adopted it for its Savage Model 99 lever-action rifles. The case was based on the .30-30 cartridge.
