I'll be honest and tell you I take spells. On the average my group size at 30 yards is more like 3"-4", sometimes 2". I can do the same at 40 most times, sometimes not. For a guy who is about to turn 52, weighs around 150 lbs. but shoots at 67 lbs., shoots a right handed bow with a left dominant eye, has to shoot with one eye closed, and can't decide whether to shoot with his glasses on or off[&:]
...I don't think thats too bad.
