Overview
Overview
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.
