At some point you may find that to get the level of accuracy you want will cost you more than what you are willing spend. How well do you want this rifle to shoot?
At a minimum, I'd like consistent 1.5" groups since Weatherby "guaranteed" that. It would be nice if I could come closer to 1".
I'm not averse to investing in this project, as long as I have some confidence that whatever I do will help.
