I suppose you can juggle figures until the cows come back to the barn! Whatever etc.
I own and hunt with a couple of .338 caliber rifles, a .338 Win mag and a .338-Edge. Now at a distance of under 300 yards they don't kill game any better than my .338-06 really......Dead is simply Dead!!! The .338-Edge will shoot flatter for a longer distance but I never saw an animal that was killed by just energy numbers.
