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. 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).
The original intent of its designers was to offer a cartridge that could approach the ballistics of the original version of the .30-06 Springfield, while at the same time using a smaller case that could be cycled through a short-action lever rifle. Although it fell somewhat short of its ballistic goals (by about 70 ft/s), its performance out-classed other contemporary .30 caliber lever-action cartridges including the .30-30 Winchester and .30 Remington. It soon became a popular deer and medium-sized game cartridge among North American hunters, and by mid-century nearly every major US firearms maker offered a .300 Savage chambering in at least one of its rifle models.
The .300 Savage distinguished itself further by serving as a peer to the .308 Winchester (7.62×51mm NATO) cartridge, a round that was developed for the United States Armed Forces in the 1950s and which is still in use today.
Despite its decline as a sporting round, the .300 Savage remains quite popular with handloaders who are able to use newer smokeless powders and more aerodynamic bullets to obtain optimum performance from it.
