I always shoot whatever bullet is the most accurate. I have yet to find a 150 grain load that shoots nearly as well as 180 grain in my Browning 308. My rifle just likes a heavier slug. As far as make & model goes, regular old Remington CoreLocts completely jellyfied the heart of the bull elk I shot last month. There was nothing left but pieces of goo. Can't get much better than that, plus they are some of the cheapest bullets out there if you are hand loading.
