I have sorta changed my mind on this issue. I believe you should establish a comfortable effective killing range and go with it. If you are confidant you can take an animal at 80 yards, then do so. Some may only go out to 40, like me, but that's all I'm comfortable with. Let's face it, some just shoot better then me and they can make an 80 yard shot as well as I can a 25 yard shot, I'm ok with that. However, a trip to the bowhunting forum in October will reveal "I wounded one" post after post. Only you know your effective range.
