RE: Backing out the limb bolts
Assuming that you need to shoot your bow set at less than the highest poundage. Screw in your limb bolts one full turn each until you bottom them out. Then back them off one turn each until you reach your desired draw weight. Tightening them all the way down first assures that the limbs have equal ammounts of stress and they remain equal as you loosen up the bolts equal turns.
