thanx for the tips...ill have to try a walk back tune and see what i come up with. i know you use a pendulum sight, but for me using a multiple pin site would i use the same pins, or the correct pin when walking back?? do you aim at the same exzact spot as you walk back?? just curious..ive heard of the walk back tune but never read how to do it...maybe itll help me tighten broadhead groups..mine are a litttle open but good enough for hunting if i left them how they are...thanx
