That is with mid-range bullet weights. There is no comparison when the real heavy-weight bullets are pushed to maximum velocity in the 460 S&W.
And You can send your revolver to Cylinder and Slide and have the barrel set back to narrow the barrel-cylinder gap. I sent my own 500 S&W in to Cylinder and Slide for an action job and they found what they deemed to be an excessively wide cylinder gap. The barrel was removed and the barrel set back to .005 which is modest and not too tight, but better than .009 or more that it was.
