Have not worked with the Rem action,but my M-70 has an HS Precision stock.
Before I considered mucking with the bedding block,I might try coating the reciever with a thin coat of prussian blue and put it together with the screws just snugged up to see how it settles in.If I had a high spot bearing hard I might scrape it in.
Before doing anything,may I ask,how does it shoot?I know you saw little marks,but,how does it shoot?
