My understanding of the D marking is it refers to the Finn’s having chamber reamed the rifle to accept the Finnish Lapua D bullet, as well as ww2 era Russian service ammunition.
Bore diameter, I have read, is unrelated to the D stamp.
When you look at rifle models, M24 and M28 or 28/30 rifles are often encountered with tighter bores in the .308” range while army rifles are often closer to .311”.
