you sir have vane contact going on. Borrow the missus' baby powder (talc) and apply evenly over your rest and arrow shelf, shoot a few then have a look to see where the talc has come off and you have your contact area. You may need to simply adjust the arrow nock, nocking point, centreshot or dropaway timing. Keep using this method until you find the culprit...or the missus catches you with her baby powder :darkbeer:
