Anyone had to deal with a loop that seems to want to walk around the string? I shoot a BT release and my peep come back nice and straight. That is until my loop starts to walk around the string. When the bow is at rest (ie not drawn), I make sure the loop is pointed straight back toward the archer. When it is like this it is fine and the peep is perfect. After a couple shots it starts working it's way around the string. If I don't move it back the peep then starts to not line up. The more I shoot the worse the peep gets. I then move the loop back to it's pointed straight back and all it good for a couple more shots. Anyone had this trouble? How do you keep the loop from spinning?
