I am new to tuning bow. I have an 07 allegiance. I have had a lot of trouble with vein clearance. I have it set now to where it is shooting bullets through paper, but you can physiclly see that the rest is too low. Weird I know. I guess my question is could my problems have anything to do with nocking point. I was under the ipression that the nocking point is set at the factory and then you set your rest off of that. So can the nocking point be changed? if so how.
