I recently "upgraded" my Weatherby Vanguard stock to a Bell & Carlson Medalist composite. I chose it because of the fitted aluminum bedding block. I was pleased as the fit was truly "drop in" requiring no additional fitting. However, at the forward end of the stock there were two raised "nubs" that seem to contact the barrel. (?) I cannot slide a piece of paper between the barrel and forearm as I believe these two raised nubs are contacting the barrel. Does this not just negate any positive accuracy gained by the aluminum bedding block by having a point of contact between the stock and barrel, especially when the barrel heats up? I thought the barrel would be free floated in this stock. Do I need to work down these nubs to be sure the barrel is free floated? It is apparent they are supposed to be there so before I start sanding I'd like some guidance from the more experienced. Thanks in advance for any help.
