Here's my 2 cents on action blueprinting so take it for what it's worth. I've done quite a few rebarrels on trued actions as well as stock actions and they all shoot the same. It's a waste of money in my opinion. The single most important factor is quality of barrel and chamber job. Get a quality barrel and save your money on the other fluff. It won't take you years to do load development or whatever. Find pressure, back off a grain and shoot.
