I echo get as close as you can and burn a hole and don't think about anything else, but my dead nutz zone is probably between 10-25 yds. I've taken shots further, but only when not thinking about the shot cause everything was right. Only pacing it out after did I realize how far it was. Still the longest shot I can remember taking was at a squirrel in my youth, paced out to 38-39yds. As a rule, I never think about yardage before I release, only after, I like to keep track for my personal knowledge. J
