First off let me welcome you to the board. Hope you can add a bit of spice to it. Lots of nice people here.
Just wondering if you have shot the Rem yet? If the accuracy isn't what you expect..before you take anything out of the bbl channel try a card or two up near the forend tip. Once that ol wood is gone..it be gone. If the accuracy gets no better. then you can try the scrape the bbl channel trick. If the rifle is a little older just make sure the guard screws are tight and start scraping the forend. If ya get her all free floated and it shoots better. then ya go ahead and seal the bbl channel. I haven't ever had to free float a rifle completely yet and never glass bedded one of my own. Not hard to do but you really have to be careful that you get release agent on EVERYTHING that might stick. Rocky can probably give you a bit more info on the rifle side of things. Again..welcome aboard!
