I shoot 165 in my 308 cause thats what shoots best. I have tried anything from 130 to 168 and 165 shoots well. And it kills.

I wanted 150gr prohunters to work, but they shot poorly.

In my opinion the 308 kicking a 165gr bullet out at 2700fps is the best balance of speed and penetration and works great to 200 yards. If I use a gameking.
