Sometimes things just dont go as expected. Back in early fall this year I shot a doe using 100gr muzzy. The arrow entered right behind the shoulder midway in the chest and then exited. I thought to myself dead deer she wont go far. I just kept hunting in the stand for another hour before getting down to look for her. I follow a blood trail for about 100yards before it pettered out. I thought to myself dang I know that was a good shot. I started ranging out in half moon type circles with each circle going deeper in the woods. Finally I came across her, she had ran over 200 yards. She was laying on the exit side and there was a hole in her flank. I thought I dont believe this (I know I didnt hit that deer there). When I rolled her over there was the entrance hole midway in the chest right behind the shoulder. That arrow turned as soon as it entered her and came out the flank. Never had that to happen before.
