This is the first one I've ever done, I screwed the barrel in against the go gauge and "felt" it several times, torqued the nut down, and that's where it was, I kind of wondered how it would line up?, a .003" shim in the bolt face with the "go" gauge and the bolt refuses to close!, factory ammo chambers from easy to you can just feel some resistance?, my hand loads all chamber easily, I got a neck sizing die for it but haven't loaded any ammo for it yet, I can get 1/2" groups out of it, I think that will improve when I bed it?, and as I said I'll make some pillars for it too.
