People who talk about Weatherby freebore are just parroting crap they've heard somewhere else and it sounds good. First, even my OLD Weatherbys are all sub MOA and since about twenty years ago, the freebore in Weatherbys has been all but eliminated with the advent of more modern powders. That and the "belt" is the other red-herring. I posted targets of my Weatherbys above, and not a peep from the peanut gallery.
A good principle to guide me through life: “This is all I have come to expect, standard lackluster performance. Trust nothing, believe no one and realize it will only get worse…”
