Wasn't able to clearly see what is on the receiver but I did notice the Tula arsenal stamp. If its a 1891/30, I would say you are perfectly fine firing 7.62x54R in it.

Can't wait to hear how shes shoots!
 
Tis a 91/30 Sniper, 7.62x54R is what it eats. If you are buying made rounds, just buy them and don't worry about it. If I recall correctly, 308 is what it is in the loading books. My friend reloads them with 308 bergers and they preform nicely.

The rifle is an Izhevsk, you can tell by the arrow in a triangle. Tula is a large star.

If its one of the recent imports, you want to read this:

Just noticed another 91/30 sniper review posted not too long ago. Guys are talking about .312. Perhaps get her slugged and find out what works best for your gun.

Just picked up a 91/30 rifle that appears to my untrained eyes to be mostly original factory refurb. All the numbers match except the scope serial #, as the scope appears to be new. More importantly, does anyone know the bore diameter of these rifles? I hear it can fluctuate between .308 and .311 in size, and I don't want a big surprise when I go to fire it, as I plan to be shooting handloads. Here's a few pictures. I'm already aware of my "skill" as a photographer so no need to mention it...:rolleyes:

Izhevsk, year 1942, refurb, regular infantry rifle worked out into a "repro sniper".
Mount and scope are modern Ukranian reproduction (Eezuum optic factory).
Common diameters for new barrel are about:
lands 7.62-7.64 mm.
groves 7.9 - 7.94 mm.

Bullets of 303 caliber (.311-.312 diameter) are recommended for reloading .

Some Finland-made Mosins had Europian manufactured barrels, these rifles had grove diameter .308 as new.

Yurs one sims to be a good example, congrats!
 
Don't feel bad about the repo sniper part. If it was the real deal, you would have paid at least $1500.

Of these repro's I've seen, they look like original mounts, but repro scopes. The repro mounts don't have the scope cover through the hole.

From memory, a real PU Izhevsk would be made from 42 to 45 only. 43 to 45 it would have a C H stamp on the barrel (one on either side of the hammer and sicle), and would have the scope serial number on the left side along just above the wood. A 42 would be proper without the C H and scope serial number. So, it is possible yours may have been a sniper prior to rebuild, but unlikely.

You mean I bought a fake? C**ksuckers! This one was being sold as the real deal. They must have stained the wood around the scope mount to make it look like it was not freshly cut. On closer inspection though, the scope mount does have the Ishvesk arrow in triangle on the mount, and whoever stamped the matching serial number into the mount must have hot-tank reblued the whole piece, because there is no bluing missing from around the number punch marks. I don't know what to think now...

1. "The real deal", generally, is not available - too few left in good condition.
2. As been noticed, it may cost You an arm and a leg (if You will find one for sale).
3. there is no cyrillic letters on the number on mount - do You really think thay had it not in Izhevsk? :D
4. If You will be so lucky to find a real Mosin sniper for sale, quite possible, You would not bye it - dings on wood and pitting on metall.
5. Just try it - finally, if it waks like a duck....

The "CH" markings were only on Tula snipers, the Izhevsk rifles typically only had the scope serial number on the left hand edge of the reciever by the stock. From what I have read, at Izhevsk, they only started to mark the left of the reciever in late 42/early 43 (I think, so there are a few without any indication at all, that are genuine - someone correct me if im wrong)
 
Regarding bore size;

7.62x54r is not a very good name for it. 7.92x54r would be more accurate. It is, and always has been spec'd at .311-.312 groove diameter, .302-.303 bore. Being military rifles there is some variance.

It's fine to shoot 308 dia projectiles in a Mosin, and you may get them to shoot accurately, however most if not all will do better with 312 sized ones.

The 174grn 312 dia (303 cal) match type bullets are the best in mine.

The exceptions (there's always exceptions!) are Finn made barrels. The Finns started producing 308 barrels and re-named their version of the cartrige 7.62x53r and using 308 dia bullets.

Lets not confuse people, 7.92 is NOT .311 or .312.. 7.92 measures out to be a direct measurement of .3168" and one runs the risk of confusing folks not familiar with bullet dia's and get mixed up with 7.92x57mm dia bullets, which measure .323"

Russian bores were made to shoot .311" ammo, S&B ammo measures .311", the Bulgarian stuff I have measures .311". If the barrel is in good shape, you could get away with shooting 7.62mm bullets but it's not as tight as it could be, I wouldn't be surprised to see gas blow back on the brass neck and shoulder when doing that.

One should slug thier bore, here's how to. ht tp://7.62x54r.net/MosinID/MosinSlug.htm

On anther note, Finnish mosins that were rebuilt and rebarreled were made to have a bore of .308, but russian captured rifles were not, the M39 has a bore of .310
