I don't usually go past 40 yards. Most of the time I stay around 20 to 30 yards. However, I must admit that after going 40 yards out a 20 yard shot is money $$$. So I use it to refocus my perspective. When I feel like 20 yards is a distance I'll go out to 40 and get a decent group. Also, at 40 yards I like the delay from my bow to the target. It's just cool to me. Release.....Pop.
ohhhhh another through tha' lungs. Besides at 40 yards or beyond there is more chance for non-human error to occur such as wind or lack of.
