I picked up my new bow on Friday and set a 20 yard pin at the shop before I left. I hit 4 out of 5 bulls eyes (1 inch) before I left. At home I started shooting dead on and then suddenly would be 6" left. My first thought was that I was over drawing but when I concentrated on that I got the same irregular results. I checked grip and peep alignment with similar results. It did seem when I shot at a 2" circle I got a much more consistent result for awhile and then it started to wonder as well. The bow is a matthews ovation set at 65# with 65 percent letoff. It does seem to be tighter at full draw than my old Q2XL. It feels like I have to really work at it to maintain full draw. Any thoughts?
