I have been shooting the Hornady 140 grain BT out of the 270 bee for a lot of years. They work on everything from elk and moose down. Totally trash gophers and yotes too. Deer are easy to kill, and IMO you don't need a high $$$ premium bullet to flatten them. I do use the partitions and grand slams on bigger things that can cause you a world of hurt, but for deer, this is not needed.
