HCRider Report post Posted March 16, 2016 Hello I know there is a formula for determining the size of chap yokes for a proper fit. Is there a similar formula to determine the size of the back belt on mounted shooting rigs? I would think that one would adjust the size of the larger oval per the size of the shooter and I want to know if there is a rule to get the correct size. Thanks Quote Share this post Link to post Share on other sites
