I would sell the Wby rifle, take your money and get a Borden receiver, quality stock and put that fine barrel blank to good use!!!
A little kidding there but really, thats what I would do. That Wby is worth alot more to resell now then it would be if its been modified by a gunsmith and there are MUCH better platforms to build on then the Wby.
I may take some heat from the Wby fans but thats just my opinion. If your looking for a rifle platform that will work every time, the Wby MkV will never make my preferred short list of receivers.
