your choices are minimal, consider a 7mm-08, 270win, or 30-06. i recommend the 30-06 because it is versatile enough that if you want to hunt any other north american game (exept birds) I live and hunt in Fla and it is a beautiful round for deer and hogs (and antelope,moose,elk,coyotes,mountain goats,bears...)
please give the 30-06some serious consideration and talk to others with it, trust me, you wont be angry with your decision.

hope I helped
