Basically I have been seeing a lot of contradictory information out there on what these guns used for bullet weights. I have the fantastic "Finnish Mosin Nagant" by Matt Di Risio and he mentions in there that 7.62x53R was pretty much a dead ringer for the 1905 Russian 7.62x54R. I take it he means the bullet weight (148 grain BT) and ballistics, because the Finns prior to the M39 were using .308. I also have been seeing that this cartridge used a D49 projectile which was around 180 grains or so.
I'm just a little confused on what Finland really used in these guns prior to the M39, which we know uses the standard Russian ammo, and all D166. What were these rifles sighted in with and issued? I am leaning on using 150 grain or so projectile. Also when casting I may go with a lighter boolit rather than something in the 314-299 class of bore riders. Anybody with knowledge on the Finns have anything to add?
