Hello all,

I recently had a post on here asking about the Finnish "mosin nagant" cartridge. I am obtaining a M1927 Finnish. Will it be safe to use Czech and Yugo 1980's military ball in this rifle? Chances are it's chambered for the 7.62 X53R Finn cartridge.

The website with specs is above. I really don't want to blow myself up lol. Advice? The difference in cases is virtually nil, but it's the 7.83 to 7.92 bullet diameter difference that bothers me.

Yours,
Drachenblut
 
The barrels built for use with the x54R cartridge (ie the russian/ czech/ yugo sorts) will be stamped with a 'D'- indicating they are bored to accept the .311" bullet. Consult your new toy for details. If it's stamped with an A or B, proceed with caution.
 
My M27 is "F" stamped and the bore is .308". It absolutely loves 190gr Berger VLD bullets.

As per previous post, check for "D" stamp and if it's there, you can safely shoot any standard x54 ammo then.
 
This is a really silly question... but how do you slug a bore without having a bazillion tools? I'm on a really tight budget (I don't have 80 bucks for tools). Where do you find leads? All that's in this tiny town is a Home Hardware.
 
"...slug a bore without having a bazillion tools..." Doesn't need a bazillion or expensive tools. Takes a .30 calibre cast bullet or suitably sized lead fishing sinker, a 1/4" brass rod, a plastic mallet and a micrometer or vernier calipre.
Hammer the bullet/sinker through the barrel with the brass rod and plastic mallet then measure the bullet/sinker with the micrometer or vernier. A padded vise makes the job easier.
It's better to hammer the bullet/sinker from the chamber end, but from the muzzle will do. The plastic mallet won't bother the crown.
 
7.62 x 53 R = 7.62 x 54R same brass case no difference. European measure in metric is slightly more precise than what we do here in Canada, My parents , both from Germany tell me that our "metric" system here is a joke and not "proper" I hear this also from many people that came over from Europe. The bullet 7.62 is another matter entirely, can be anywhere from .308 all the way up to .318 . I'd slug the barrel. I have a mosin that is loose enough to let a .311 just drop straight thru , it turned out to be .315 after slugging it . My second mosin is true .308 .

I think buckshot is .33 isn't it? Buy a five pack of 00 and cut one open, you've got a suitable slug. And don't forget to do a real through job cleaning the bore and most important; Lube. I used 'Bore Butter" to do my 38-55
If you can't get a brass rod maybe you can "flange up" a short brass plug to attach to your cleaning rod. You probably want to use a "starter rod" to get it in the 1st 4-6". After that it'll probably go pretty easy. But I wouldn't hammer on the cleaning rod; try picking it 6" of the plug and tapping it down by hand if you are going to try that way.
But Sunray is right ; brass and plastic are not going to damage the bore. I used a hardwood dowel but my bore was .38 cal.
Good luck
