Re: OCW test with PP 2000 MR .308 @ 200 yards.
I believe I would go with the 46.2. The method as I understand it is to narrow down a charge that has larger window of accuracy to either side of the given charge to allow for subtle changes in temperature etc that would otherwise swing accuracy greatly. at 46.2 you have such from what I can see. With all the charges hovering around MOA, if this were my rifle I would call it good. You may tighten that up even more if you have not yet tweaked in seating depths.
Of course, If I am off base in my understanding of OCW, then the above is useless.

We are very close to this point now.
