If you are happy with 1" groups, then I agree, a standard sporter contour will fit the bill. However, you will have to rebed. You cannot put a remage system into the old bedding without redoing it. You will also have to relieve a large chunk of the aluminum substrate from the front of the action area to accommodate the barrel nut. I had a real good look at my B&C Mountain Stock. Relieving the stock will weaken it. I can't say if it will break as a result, but I would be concerned about it. If you search the web for Bell and Carlson Mountain Stock, you will find lots of hunters who have broken their stock at that location. So it's already weak there. I agree, it's not Tupperware, but it isn't exactly high quality either. B&C makes the Synthetic stocks for Cooper. Those stocks also have bedding blocks but they are drop dead gorgeous and much higher quality - not at all like the Remington. I have one of each.
All that said, I get it when someone loves something. It doesn't have to make sense to me or anyone else. But please do your homework. Check out how much you are gunna have to modify the stock to accommodate the remage barrel nut system BEFORE you get locked in. Removing old bedding is no big deal - but you can't restore the forend after you remove enough meat to clear the barrel nut.
If you really love the stock, then my advice is to forget the Remage system and stick with the standard Remington shouldered barrel system so you don't have to modify and weaken the stock.
