It is my sons first year bowhunting and he is pulling back 45#. he shot a doe in the shoulder blade and the arrow stuck out of her and she ran off. whe never found a piece of the arrow and fallowed a blood trail for about 200 yards and it must halve clogged up and we never found her. and i also shot many deer in the front shoulder blade with great penetration but couldnt find them so i am wondering could a shot in the front shoulder blade kill one?
