The.303 Savage is a rimmed, .30 caliber rifle cartridge developed by the Savage Arms Company in 1894 which was designed as a short action cartridge for their Savage Model 1895 later 1899 hammerless lever-action rifle. The cartridge was designed for smokeless powder at a time when black-powder cartridges were still popular. The.303 Savage round was ballistically superior to the.30-30 Winchester, but only marginally. The.303 Savage remained popular through the 1930s. Savage produced a half dozen loads for it. With its 190-grain loading, it was used on such animals as deer and moose.
