I know for a fact that a 60gr Nosler Partition will drop deer pretty regular, neck or hart/lung shot, tracking ranged from 20yds to 110yds. Ive been experimenting over the past four monthswith the Barnes Tripple Shock 70gr, found my load of 23.5gr of H-4895, Federal 205M primers through my DPMS varmint rifle 1&9 twistwill group 1/8" at 100yds, now if the bullet will perform like Barnes claims, that should be a deer killing round.
