ive always thought that even with the fastest bow, a deer can take a casual step and turn a good shot into a bad one in a split second. ive had deer react to the shot at 30 yds, let alone 60. a stationary target is one thing, but a living and, possibly, moving critter? i dont think thats a great shot. if you could guarantee that deer wouldnt move, then take the shot. Otherwise, youre gambling.

ps -i know deer can be taken at those ranges, i've seen Nuge do it on TV, but i just don't think its a high percentage shot.
