For as many medium caliber rifle hunts I've had I could honestly say I would have been fine using a 30-06 or 270 on any of them. To me the 30-06 and the 270 are the epitome of ideal cartridges that would MAKE the ideal elk rifle a reality. Much of this has to do with the terrain I hunt in and the style of hunting I do but also the cartridges themselves are both very capable on Elk and larger size game. Not in an ordinal ranking but the 270 still has quite a wallop on game.
