I dont know your experience but I can tell you a 270 will do just fine on deer and wont have as much kick. Good Luck this coming season and keep us posted.
Just seen what unc matt stated and he is dead on.

I am going to be buying a gun for this years hunting season. I was originally looking at a .270 but I don't know for sure yet. My dad has a .300 H&H Magnum and I was wondering if I could get away with using that on deer
