Response to too late for me to send back.
Disco gradually drops POI after 20 shots...but no left/right POI shifts..it is tuned to shoot 906 FPS using JSB 14.3 gr....factory stock,with barrel band in original position...and factory muzzle brake..

If you still have your Discovery stock,I'd try that first and compare results...
