The factory bedding was nearly perfect on my 550 9.3X62, just make sure that both recoil lugs are bearing evenly and there is some clearance at the tang. If the action and barrel recoil lugs don't bear evenly then glass bed, especially at the lugs. Bedding in the wood is fine if done properly. The wood should be treated inside and out with a water resistant finish. Glass beading compound of course seals the wood where it is applied.
