Haven't you guys been reading the hunting magazines? The 338 win mag is the absolute minimum for elk!
It is actually one of my top picks for all around versatility... but that doesn't mean that others don't get it done.... I carried a 243 once.... never had a shot but had no issues... knew I'd have to be a bit picky but beyond that no biggie... the nut behind the butt is more important really.
That being said there are a couple of other issues.. projectile choice can make a HUGE difference in the ability or lack of in a round. And optics on the gun better be good... after all if you can't see it, you can't shoot it... if they are not at least as good as your binocs, you spin your wheels.... I"d take good glass on a H/R handi rifle any day over a higher buck gun and cheaper scope.
