Finn Mosin Questions

.308 bores?

Bore SHOULD be .300 (ish)

Early Russian designation was; "Three Line Rifle"

A "Line" (ancient Russian unit of measure), is close as damnit to 0.100 inches; thus "3 Line's" is pretty much .30 Cal.

GROOVE diameter, like the .303 Brit is a bit of a crap-shoot, as you American cousins say, but should run .312" to .319".

It worked in 1891 and is still working today.

Finn supplement: check out the Finn TKIV-85 "update" of the old Nagant: .299" bore, .309" (ish) groove. .308" MATCH bullets out of the 7.62 x 54 case. Complete round of such is called the 7.62 x 53R. SERIOUSLY competitive rifle / ammo combination.

Had a gunsmith slug it. .312

Only shot out to 70 yards, but it liked the milsurp silver tip ammo

That is on par with where my Russian 91/30 slugs out, should make ammunition supply fairly easy with a lot of off the shelf offerings.
