The .250-3000 Savage (also known as the .250 Savage) is a rifle cartridge created by Charles Newton in 1915. It was designed to be used in the Savage Model 99 hammerless lever action rifle. The name comes from its original manufacturer, Savage Arms, and the fact that the original load achieved a 3,000 ft/s (910 m/s) velocity with an 87 grain (5.6 g) bullet.^[2]
