have you paper tuned the bow already,what kind of rest do you use--are you fighting a little target panic perhaps---what about tourqing the bow---make sure your bow hand is the same each time and follow through is good. the xts are a good shaft and should shot well as long as they are spined right for your set up.has it been a while since you shot your bow? if so it could be you are out of time---either string stretch or cable stretch which in turn will change your draw length.which in turn changes your brace height--check to see if it is right. just a few suggestions if you have not shot in a while give yourself a little time to get back in the groove.
