I shoot a recurve, and 15 yards is ideal...20 is good. In the right situation, with good light and a relaxed deer, 25 is acceptable for me. It's not that I'm not accurate further, it's just that at 170fps a deer 30 yards away has .53 seconds to react.

An alert deer has time to make a sammich and have a cold beer in that amount of time. <img src=icon_smile_big.gif border=0 align=middle>
