I finally got my boys arrows cut and we shot for the first time today and we have a problem. His nocks are really, really tight. So tight that when he shot three of them, the nock stayed on the string and arrow went off target. I have to really snap them on to get it seated all the way. His arrows are Easton Jazz's Can I heat them up to open them up or something? Or Super glue them back on the arrow and wear them in or what?
