Cut a length wise strip of sand paper about 1 1/4" wide. Slide it between the barrel and the stock with the grit side facing the stock of course. Pull it back and forth till you have the clearance you want. End of story

That is pretty much guaranteed to scratch the barrel finish.....ask me how I know.....Pulled sandpaper under Kreiger varmint weight barrel fitting it in a Remington factory stock. I did not have to remove much material and the barrel-stock space was pretty consistent when finished, but some grit got between the back of the sandpaper and the barrel which fixed the bead blasted SS barrel finish. Most of it was hidden by the stock, still..... Maybe some masking tape or electricians tape might save barrel finish.
