You probably already know this, but just in case, make sure you are not resting on a hard surface. The gun can bounce and cause it to shoot high.

Other than that, tear it down, remount the scope, sight in at 50 yds. Then shoot at 100 yds, and adjust scope to hit dead on. Then shoot at 50 (which is my normal range for most deerI shoot). My guess is that you will not have to think about elevation for shots out to 125-150, assuming a mid-chest aiming point.
