The 307 Winchester cartridge was introduced by Winchester in 1982 to meet the demand of .300 Savage performance in a lever-action rifle equipped with a tubular magazine. It is nearly dimensionally identical to the more common .308 Winchester cartridge, the only differences being a rimmed base and thicker case walls.
The Winchester Big Bore Model 94 Angle Eject rifle was the only rifle produced to fire the cartridge, though competitor Marlin Firearms created some prototype model 336 rifles chambered in .307 Win. It is still commercially loaded today, but many handload to gain better performance and accuracy. Because of safety concerns owing to the rifle's tubular magazine, flat-nosed bullets are normally used.
The .307 Winchester cartridge sees widespread use today, especially among sporting shooters in Spain, due to Spanish gun laws that prohibit civilian use of "military calibers" such as .308 Winchester-the civilian equivalent of the 7.62x51mm NATO cartridge.
