On most Hoyt bows the maximum number of turns that you can turn out your limb bolts is eight (8). The Hoyt Ignite model bow can be adjusted out ten (10) turns. The amount of weight that you will lose varies from bow to bow and turn to turn. The only way to know how much weight is being lost is by measuring it on a bow scale.
Weight adjustments can easily be made by turning the weight adjustment bolt or limb bolt (tiller bolt on recurve bows) clockwise to increase weight or counter clockwise to decrease weight. You should always turn the top and bottom adjustment bolts in equal amounts. Be sure to unstring recurve bows before making adjustments.
