6'3" and 220?? For a 15 year old nub, you be a hoss!

Main thing you want to remember is it doesn't matter what someone else's accurate shooting distance is. You gotta work up your own distance and hunt within your own limits. The first year, you might not be comfortable taking a shot beyond 10 yards. After some time, practice and experience, you might be able to stretch it out a good ways. But, when hunting, you've always got to stay within the limits where you're reasonably sure you can put that arrow exactly where you want it.
