I just acquired a revolver in .45 ACP caliber, 5-1/2" barrel. I have had a 1911 .45 ACP for some time, with a 5" barrel. Since they both fire the same ammunition, my mind began buzzing with the following puzzle.
Using the same box of ammunition for both weapons, would the balistic performance of the bullet fired by the revolver be superior to that fired by the semi-auto? Would the muzzle velocity be greater? Would the muzzle energy be greater?
The basis of the question is that the .45 ACP cartridge is being held rock solid in the revolver, as it fires, while there is the semi-auto mechanism to operate in the 1911. What percentage of the propellent energy is used to cycle the 1911? What percentage velocity and/or energy improvement might be realized in the revolver?
