I guess it depends on where you hunt them , but in my limited moose hunting experience (once in Alaska and once in Montana) I would probably choose a 270 for a moose before I would use it for elk. Moose didn't impress me as being near as wild as elk and neither showed any inclination to run very far after the shot. It also seemed easier to get closer to them than elk. So I would have no qualms at all about shooting one with a 150 gr partition from a 270 out to 150-200 yards. Your experiences may differ. Course the "Is the 270 big enough" has been debated ad nauseum, but that wasn't his question...
