I think they start with a fresh rifling tool (larger bore dimension) and use it until it is worn slap dab out (smaller dimension). So that is what produces the variations from around .308" to .314". You just have to find what bullet fills the bore and have at it.
I sadly sold a Sako re-produced, Fin captured, and rebuilt, Nagant. It was actually really nice, good sights and trigger, the equal of about any military type of that era. We bought a couple of the 880 rnd. tin boxes and had a blissful time blowing large fireballs.
