I didn't see it so I can't comment on it.I to believe Dwight to be an extremely accomplished and ethical hunter.In a recent bowhunter mag I read that he just qualified to run the Boston Marathon,he's in his 60's.
I havn't read the article discussing frontal shot's on elk.It would seem that the margin for error or kill zone would be very small,and no possible chance for a pass through obviously.I am interested to hear more about it,although I can't imagine feeling comfortable taking such a shot.
