What kind of velocities does .460 S&W get out of barrels 18-22 inches in length? It’s already moving fast in pistol barrel lengths so it should be moving along pretty fast out of a 22 inch barrel. Also, I have heard .454 casull can be fired in weapons chambered for .460 S&W. Is this true? Would they still cycle reliably in a lever action? How does .454 do out of a barrel of the above mentioned lengths?
