Has the rifle been bedded? If not, that is the place to start. Bed the action, wrap a few wraps of tape around the barrel to keep the front up and centered, bed the action and floor metal, and add pillars for the ultimate. Then you can be stress free and it will be a non issue. I would swing for .020 clearance on a walnut stock from the factory at the barrel.....they do not always use the best wood.
