R.Marshall,
With regard to the drilling with CZ ring, I suggest you "drift" the dovetail plate the front ring fits into, opposite the direction you need to move the POI. You will be surprised how much the POI moves with a small movement of the plate. The Scherping will be more troublesome. You bay be able to get a useful
zero" by varying the load. We don't know if it hits high or low, and by how much. Also we don't know particulars or the load or the distance to the target. BTW, Waidmannsheil.
