30-06 would be a lot better, but a 270 would do... The 270 has to much powder for the size of bullet, so when you shoot something with it, your gonna have a big patch of jellied meat around the bullet hole... Not to say a 30-06 wont do that but it wouldn't be as much wasted meat... with the 30-06, you can get a HUGE choice in diffrent ammo, I think you can get the bullets up to 210 grains, and that would bring an elk down very well!
