I shoot a bow the same way I would try and "bean" someone with a rock. I would never shoot at a deer with trad gear beyond 22 yds, but last year I killed a doe at 27 yds with a perfect shot. That is sort of contradictory huh? Guess what I'm saying is I did'nt think about the distance. The shot felt right and I took it. I have let several deer walk at ranges of 20 yds and less because I just did'nt feel confident in making the shot or it did'nt feel right.
Think about this: Everytime you consider taking a shot at anything (target or game), you have a level of confidence in whether or not you can hit what you are shooting at. If you want me to shoot at a coke machine from 10 yards for a dollar a shot, I'll shoot till I can't draw my bow or you're out of money and I bet you would too. That is the level of confidence I want when I shoot at a deer. Sometimes it happens at ranges longer than I expected. Interestingly, the bad shots I've made on deer have been chip shots that I must have taken for granted or lost concentration on, but I think I learned from them.
