Personally I'd run one of the lightest hollow point bullets you can find for the caliber.
I was running Sierra 110 grain hollow points in my 308 for deer hunting. Holy smokes did that do a nice job on white tails. Guides always commented on the minimal meat damage and obliterated internals like they never saw before.
You need to forget about the need for penetration. You'll get all the penetration you need with any center fire. What matters most for deer is that you get fast expansion. Think like you want a varmint load for the 270.
Even a 223 with 55 grainers will pass through a deer clean, so that's the least of your concerns.
Just remember that any energy left in the bullet after it passes through the animal is wasted energy. Deer are smaller than most people think, so don't go out there with a gun that is set up to kill moose when you are after White Tails. I've tracked more wounded deer that were shot with a 300 win mag than I can count, so over kill is actually less effective or even worse... ineffective.
I remember the sales guy at work paid for a deer hunt on a game farm in Michigan for a good customer who wanted to shoot a deer with his deceased brothers 300 win mag. If you could have seen the look on the sales guys face when he counted out $5000 for a deer that was not recovered. We found lots of blood, but not the deer, so he had to pay up anyway.
