just for kicks i set up an old compound browning bushmaster that has never been shot and was bought back in the 80-s. i put a site on it and a whisker biscuit but when i put my center shot guage (the type with the rubber cord and allen rods) on it the true center shot couldnt be adjusted without the vanes hitting the riser. is this common in a molded riser bow? im gonna shoot it anyway but it is more that a 1/4 inch to the left of this right hand bow and the fletching clears barely. can a bow shoot accurately with a center shot out of whack?
