.300 Savage
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 99 hammerless lever-action rifle.[4] Despite having a short case 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).
