two suggestions , try 150 gr federal fusions ( cheaper and accurate in my 270 wsm ) , adjust your shot placement . as everyone else has stated the hump shot is exremely effective . another very effective shot is the direct shoulder shot , as in directly in the broadside shoulder , directly in the shoulder with a 3/4 facing shot , and lining up the vertical crosshair with the off leg in a 3/4 away shot . all puncture vitals, hit solid bone and prevent running by destroying shoulder bone , ligament , tendons and muscle.
