I might add that action screws that protrude from the recoil lug on the actions mentioned, should bottom out on the bedding. This is to help prevent the action from deflecting when torqued, as John mentioned. It’s a good idea to bed an inch of barrel beyond this type of action.
Actions with actions screws behind the recoil lug should have clearance under the recoil lug. Failure to have clearance can cause the recoil lug to hang up on the bedding and deflect the action when torqued excessively. This can happen just as easily as the latter.
A dial indicator is a good tool to diagnose bedding problems on free floated barrels. Indicate on the fore stock while referencing from the barrel. Tighten and loosen action screws and observe. I am not satisfied with the bedding if more than 2 mil of deflection is observed on the dial indicator.
