Re: got a chance to get a new gun!
The 270 you already own will do what you're looking to do, as stated in your post. That being said, you could get the 300 win mag if that's what you're leaning towards and have it if you ever hunt elk. If you really want something bigger to hunt elk/bigger bears/moose with, get something along the lines of a .338 win mag. Not that other calibers won't do it, but that's one of the more common ones if you want something above 30 cal. The 06 performance will be comparable in performance to your .270, so I wouldn't personally bother with it.
