Just a vote for Dave's method. I had to remove what I considered to be a considerable amount of wood from a Richard's Micro-Fit laminated stock's channel to get my Mark X Mauser barreled action in there and free floated. The barrel, though, had uneven gaps on either side when the action was screwed in. Prior to bedding, I used the tape ring; after bedding, it was centered in channel and consistently shoots under 3/4". This sticky is worth its weight in gold--probably has helped hundreds like me. Thanks, Dave!
