For white tailed deer deer no need to trade. If you are into hand loading, the 300 Win. Mag. will give you a ton more alternative loads. I have a 300 Win. Mag. and love it. 200 gr. Nosler Partition ... sub MOA hand load ... 300-350 yard shots at mule deer were not a problem. Missed a badger at a ranged 455 by a few inches. Never hunted elk, moose or bears. I would think the 300 Win. Mag. would be better on larger game than the 7mmm Rem. Mag. It can handle heavier bullets. But just a guess.
