I bed the receiver so it's super solid. Not sure how a rear action screw works, haven't seen one.
I have the lug resting in glass as it pulls downward on the action/barrel junction. Not sure if that helps, just seems to me it should dampen vibrations and stop any lateral movement.
A tight barrel/action fit is good. I had to slowly cut the Clark/Walther barrel shank to snugly fit in the action. A tight fit cuts down on slop and has to have a positive effect on vibrations.
