I have killed a lot of elk with a 375H&H. In fact I have killed more elk with my 375 than any other rifle I own. But I carry it not because it kills elk "better" than smaller guns, but because I think it's a better option to ave in hand when and if I have a mad grizzly facing me when I am hunting elk. But out of the dozens of elk I have killed and the hundreds of elk I have seen killed I can't say a 338 is any "better" at killing them than a 30-06, 270 or 7 Mag, as long as the elk are hit with a good bullet in the correct place.
I'm still trying to wrap my head around this.
