I am not criticizing you at all...deer hit through the center of the lungs do not go half a mile. therefor you actually hit him somewhere else (fletchings CAN decieve), or your arrow deflected internally (very possible if you are certain of your shot) I had it happen once, with luck it deflected 3-4" up a ribto the spine.

I agree with you. wait wait wait....its a lesson you wont forget, i havent.
