The .300 Savage cartridge is a rimless, .30 caliber rifle cartridge developed by the Savage Arms Company in 1920. It was designed to replace the less powerful .303 Savage in their popular Savage Model 99 lever-action rifle. Despite having a short case and a rather stumpy neck, the cartridge is capable of propelling a -grain ( g) bullet at over ft/s ( m/s) with an effective killing range of over yd ( m).
