When shooting out to 40 &50 yds. my grouping is in a vertical postion. My arrows are hit great left and right. They just seems to walk up and down. I check my nock point and it seems good. I assumed it was a timing issue so I tried to creep tune or super tune as PW calls it. Second problem. I' m shooting a Merlin Max 2000 with timing indicators on the cam module. When I twist my cable 1/2 twist it puts my cams out of syns. What am I missing? When I twist the cable I' m taking it from the cam end. Should I be twisting the cable from the Limb end where the cable hooks to the limb? Thanks JERRY
