I just got to looking over my bow over the weekend. I noticed that the felt that is under my string on my upper limb tip is pushed off to the side. It might be hard to explain, but it looks like the string is not hitting in the middle of the limb when I shot, but is making its way over to the string grove. The felt is pushed over to the one side. The bottom limb does not have this going on. I unstrung the bow and layed it on a flat surface and the limbs do not appear to be twisted,and when I draw back and let down slowly, the string lands right in the string grove. Any ideas into what might be causing this?
