The .300 Savage cartridge is a rimless, .30 caliber rifle cartridge developed by Savage Arms in 1920. It was designed to replace the less powerful .303 Savage in their popular Savage Model 1899 hammerless lever-action rifle,[5] which they started to produce again as Model 99, as well as the new Savage Model 1920 bolt-action rifle. Despite having a short case in order to fit the original Model 99 magazine[6] and a rather stumpy neck, the cartridge is capable of propelling a 150-grain (9.7 g) bullet at over 2,600 ft/s (790 m/s) with an effective range of over 300 yd (270 m).[7]
