I believe that if the 356 was load in a bolt action you would have 358 velocities it is the gun action not the cartridge that is the controlling factor. Both have the same volume!! Cheers NC
The .356 is a 52,000cup cartridge just like the .358 Win so no trouble there.
The interesting thing about the Winchester Big Bore cartridges is with appropriate powders they run out of case capacity as they reach their maximum pressure. Easy cartridges to load. The Model 94 Big Bore rifles have excellent case life with high pressure loads.
