When I started deer hunting in the early 70's I was loading a 180 gr. Hornady RN bullet in my .308 as were lots of other hunters in .30-06 as well. I shot the biggest whitetail of my hunting career with that bullet, a massive northern whitetail that field dressed 254#. I have since gone to 165 gr. bullets in my .30 cals., somewhat less recoil and just as effective.
