thanks guys.

i went back and looked for contact and could not see any, but just to be on the safe side i changed the tall forks on the qad to the small ones and re-adjusted everything. after i was done i was able to put all arrow in the 2" ring at 20 yards. i have not been able to shoot past that, but i think that answers my question and i must have been getting some contact or the qad was bouncing up and hitting the vanes.
