Datamax, first of all DUDE. Finding elk and calling them is acctually easier than you think. Usually when a bull comes in he is charging for all he is worth. Alot of times the elk is in your lap before you know it. That is why I said that drawing is the hardest part(timing). I have never taken a bull over 20 yards and most are under 10. If the bull is barreling down on you and you draw just when he decides to stop and take a look around. He could leave you sitting at full draw. I too have taken many bulls and was just sharing my experience. if you say the right things to them they can't help but come in to investigate, and it is usually fast. As far as crossbows. No comment.
