Making a sharp bottleneck cartridge work in a revolver can be done, but you have to do it the right way. Look up the 44/357 Bains-Davis. It is a 44 Magnum cartridge necked to 357. It will give rifle velocities out of a revolver BUT you have to use a little collar that goes around the neck area and seals the chamber, allowing the case to move in the cylinder after firing. Just chambering a revolver cylinder for a bottlenecked cartridge puts a solid surface in front of the shoulder, and when the cartridge is fired the pressure will push the shoulder forward and the head backwards so tightly that the cylinder cannot turn. So, could you chamber a revolver for 256 Winchester? Sure. Is it worth the trouble? I don't know, it sounds like a fun jackrabbit gun!
