As others have said, either round is a deer killer. If you ever intend to hunt bigger game, the 30-06 might be a better choice. But for deer and yotes, the 270 is a fine choice. Bullet selection is the bigger issue. For deer at under 200 yards, I would use a controlled expansion 150 grain bullet. 130's tend to destroy a lot of meat up close. You don't NEED a premium bullet to kill a deer, but I like Nosler PT's, as they expand, but still penetrate, and don't blow up at close ranges. Use cheap ammo for practice, and one box of the premium stuff will last you quite a while for shots at game. 110 / 130 grain bullets will work fine on yotes, as long as keeping the hides is not an issue. The 270 shoots a little flatter then the 30-06, with a little less recoil, but the differences are small. Frankly, these days caliber is not so much an issue with me as is the rifle I am using. It pays to handle as many as you can, and see what you like, caliber, within reason, being secondary. Since you are buying new, a 25-06 would also be a great choice for what you want to do. I would not make a selection based on what others are using, pick whats right for you.
