No idea. .460? Yowch. I don't dig recoil that much, 'course I know they're big heavy guns, which is why I like to hot rod my .41 Mag SBH Hunter. It's so heavy it just soaks up the recoil. I will have a .414 Super Mag built & while it's a beast, it ain't nowhere near the modern big boomers.
You oughtta see the light show my .357 Max with a stiff pour of IMR4227 pushing a 200gr 1500+ fps produces at night. The b/c gap flash is stunning š 2400's supposed to produce even more flash than 4227 & I've thought about loading some up with it, for nightime shenanigans 'round the next camp fire.
