As many have mentioned, being an excellent shot out to 60, 70, 80 yards really doesn't have much to do with shooting a real flesh and blood animal. As someone mentioned, the target animal can easily take a step or two that could prove disasterous. I feel confident in shooting at a relaxed animal out to 50 but after that, quaility shots become a LOT more difficult!
However, regardless, bowhunting for me has ALWAYS been and will ALWAYS continue to be a close-range, in-your-face, sport!
