I didn't "get it" before how the rear shims lift the action rear end up in order to cause a forward tilt of the action at the action screw, and thus help to get the desired barrel down-pressure at the front of the stock.
The stock draws slots unfortunately then must be re-shimmed as the angle is changed from the action tilting forwards.
