I bought three Lumenok bolts for my crossbow and was sighting in my scope with them. They were a little difficult for groupings until I realized the nock was moving around everytime I turned them off. This caused them not to be in the correct position in the bow. Does anyone else have this problem, and how do you make sure it is lined up properly?
