I am getting ready to tackle my first bedding job on a project rifle that I have. It is a Remington LA and I am putting it into a new Bell and Carlson stock. I have watched a few videos on you tube and all of the ones that I have watched take a dremmel tool to the stock and grind out almost a quarter inch of material before they apply the bedding compund. Is that really nessassary? Reading the instructions that came with the bedding material that I bought only says to rough up the surface to be bedded with a good 80 grit sandpaper. I need some help on this one guys. Which way should it REALLY be done?
