I just called my wife and told her about the discussion on the board. I bet her last night that there would be debate about the shot placement and penetration of the elk's leg bone. I didn't agree with his thinking that 8 " of arrow was enough to get to the elk's pump station. I was very surprised with his shot, usually he is right on the mark. Too bad he didn't take that opportunity to emphasis or admit that everyone misses the mark sometimes, but you need to make sure you do everything you can to ethically harvest the animal.
