Cartridge History
The .356 Winchester is a modern rimmed, bottleneck cartridge developed for strong lever-action rifles, most notably the Winchester Big Bore Model 94. Winchester's pre-1992 Model 94 manual specifically addresses the .356 chambering.
Rifles Commonly Chambered
- Winchester Model 94 Big Bore rifles originally produced in this chambering
- Modern reproductions or custom rifles only when specifically marked for .356 Winchester
Compatibility warning: Winchester produced multiple cartridges with similar names and many rifles have been altered during their service lives. Verify the exact chamber marking or chamber dimensions before ordering components.
Legacy
The .356 Winchester offered Model 94 hunters substantially more performance than traditional medium-bore lever-action cartridges while retaining the compact handling of the rifle.
Did You Know?
The .356 Winchester is not simply a rimmed .358 Winchester for casual interchange. Use only brass, dies, and data intended for the exact chambering.
