The .270 is one of the best all around deer cartridges IMO. Whats your favorite load with it so far? My father hunts with a Ruger M77 MKII all weather in .270. He used to handload for it until he tried some 130 gr. Federal fusions. He shoots consistent MOA groups, and all the deer he's shot with it were DRT if he put it in the right place. I use 120 gr. fusions in my .25-06, same results. My wife shoots 95gr. fusions in her .243, same results. To the OP, If you end up buying a rifle in a pretty common caliber, I strongly recommend trying a box of Fusions. Unfourtunately they aren't offered in many uncommon or obsolete calibers.
