The reason there a mountain of discussion is because there is no easy answer. No one size fits all. One thing I have found there is a lot of variation of free bore from barrel to barrel. I just finished measuring four different barrels from four different barrel makers and they had .160 difference of free bore from shortest to longest throat(with the Hornady 123 SST).
As Sneaky recommended, when you get your barrel, measure the chamber throat using the bullet or bullets you're going to use and seat to the appropriate COL. Finding the bullet weight that is most accurate in your rifle is trial and error. Lots of variables to work through: bullet manf., bullet weights, how much free-bore jump, powders, primers, brass, to mention a few.
I guess I wouldn't get all caught up in the general discussions. Get your barrel, measure it, decide what you want out of it. Then you can ask some specific questions that someone here probably has some first hand experience. JMHO
