.303 Savage

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.
History.
Savage Arms created the .303 Savage as part of an unsuccessful attempt at creating a cartridge for the military. Although the cartridge was never popular with the military, it did become a popular round for civilian hunters. Being a pointed-tip rimmed cartridge, it worked well in the Model 99 rifles that Savage produced because of their rotary magazine. It wasn't as successful in other lever-action rifles because of their tubular magazines. However, the pointed-tip bullets gave it a ballistic advantage over other traditional lever-action cartridges such as the .30-30 Winchester.
Reloading.
The .303 Savage has a small, but loyal fraternity of shooters who reload this cartridge. While major ammunition manufacturers have long since halted production of ammo, dedicated followers can procure loaded ammunition and brass cases through smaller enterprises. The brass cases can be formed from .30-30 Winchester, .32 Winchester Special, and .38-55 Winchester casings.
Non-compatibility with .303 British.
The .303 Savage and the .303 British cartridge are not interchangeable with each other. Neither the bullet diameter nor the cartridge dimensions are compatible.
