I did mine last night and it worked out real slick. I mounted the scope solid making sure the cross hairs were level and plum. Then I set that in my shooting rest, with the bore out. Put that on a table 13 yards from a door knob. Adjusted the bench until the door knob was clear, looking through the bore of the rifle. Then sighted through thescope to the door knob. Actually I lucked out and it was right on the money. My first three shots today at 50 yards were only about two inches from where I wanted them to be, a little low and right.
