I have been very satisfied with Hornady 139 flat base. Dependable accuracy and dependable performance on Mid size Tennessee deer. Last year I tried Sierra Prohunter in 120gr. On high lung shots the deer all ran farther than with the Hornady I had used. Yes the deer were one shot kills and the shots did not hit the heart area. Very little blood trail and exit holes were pencil size. It is my opinion that the Sierra Prohunter bullet is a harder bullet than is ideal for smaller whitetail deer. The Sierra Prohunter is a good bullet but he GameKing is probably better for deer. I am going back to Hornady interlock soft point because of the supply on hand and previous experience..
