Clearly "some" lost deer and probably a significant number. On what should be "gimme" broadside shots, the tendancy of the shooter to anticipate recoil causes POI to be higher than POA and you get the high hit. It is probably an argument for moving the POA of a firearm farther forward than that of a bow, directly over the hinge at the elbow. A high hit breaking the scalpula and perhaps affecting the spine at the point where it is rising to form the backbone is better than finding "no man's land" farther aft. This is not an archery option, but is with a firearm, particularly with a heavy bullet.
