two of the three rifles shot better after adding the pad under the shank than when just bedding the action and bottom of the lug. My thinking was the angled screw might be sucking the front of the action under when the screw was tightened fairly tight, not farmer tight even though I spent much of my time on the farm. I don't know that to be the case, but both shot better with the shank bedded so I stayed with it.
