Hmm, well I can certainly understand that theory & that practice.
It does sound like a valid point.
I don't bed back there to absorb or spread the load of recoil, my only intent is to assist in the lateral alignment of the barreled action in the stock.
I would have to guess that your concern is valid and can only stand by & wait for someone else to chime in with an opinion.
I don�t think it�s likely I�ll crack the stock but I understand what you are saying. It�s the same reason I re-drill my action screw holes after bedding.
