If it is a decent shot then why does hunter ed. class teach that it is acceptable only for rifle? Arrow that passes between lungs and throat ain't gonna do much for a while. Chance of blowing through guts which doesn't help the meat. Yes you can get lucky and hit an artery or shoot low and hit the heart but it is not a very good percentage shot. I have never had an elk go too far with a lung pass through and that is my favorite shot. That said no one is with you when you pull so it is a personal choice.
