Here is a rifle I just got. The caliber as well as the maker is unknown to me (pic of the entire rifle is in my forum introduction)
Barrel markings from under the handguard:
most left is the serial number also found on other parts of the gun - most right I think is the date Dec 1905 (but I would like to get an experts opinion on that)
The number under BGU I read as 527, which I can not make sense off (it is not 459 which would be 5.6mm or .22 )

On the side of the barrel is this:

What I found out about the chamber:
It nicely chambers a 22 short or 22 long. A 22 LR does not full fit into the chamber but it gets pushed in (as in breech seated into the rifling) when closing the action (see pic below)

Results I got from shooting .22 ammo / slugging the barrel:
The barrel looked bright and shiny, almost like new, and after measuring the barrel I felt comfortable shooting a CCI CB short (710 FPS), which got stuck about 10cm before it exits the muzzle, the bullet was easily pushed out with less effort it usually takes to push a cleaning brush through a barrel. The stuck bullet is sown on the very right, it measures 5.52mm in diameter (before shooting it was 5.7mm)
Next I tried a CCI .22 CB long (also 710 FPS), which also got stuck at about the same distance from the muzzle. Resulting bullet is shown in the middle, which measured the same 5.52mm.
Then I tried the "breach seating" a .22 LR through closing the action. Result is shown on the left (you can barely see the riffling marks on the first ring)
Then I got brave (or foolish) and shot the 22 LR (1200 FPS), which worked just fine.

Now the questions:
I am wondering what the barrel markings indicate !?!?!
Is it save to shoot a 22 LR, or maybe a regular short or long (other than CB) ???
I was hoping I can use this as an indoor training shooter with 22 CB, but that's obviously not happening. What are other peoples experience with shooting 22 CB with long barreled riffles ???
This is the longest 22 (if it actually is that) I own by far. AND I have heard that 22 CB ammo looses it's energy really fast in long barrels.
