I guess I would be considered the exception to the above (at least partially). I would set the pins at 20 - 30 ad 40. Once you have them sighted in and are comfortable shooting your new bow at 10 or 20 yds, go out to the 30 or even the 40 yd mark and practice. If you can consistantly hit your mark at the longer ranges, the 20 yd and under shot nomally taken at game (eastern) will seem like a gimme.
Remember two things if nothing else. Do not tense up shooting your bow. When you get tired - STOP. Nothing ruins accuracy more than a tense bow arm/hand. Secondly, You will never be able to hold your bow dead still. There will always be some movement. Practice will decrease this movement. Just concentrate on your release and you will do fine.
