Technically, a M88 commission rifle that has had the "S" conversion will shoot modern 8mm ammo. Not real sure if I would do it though.

Also a great many US Krag-Jorgenson's are antiques although ammo isn't as common as it once was.

Also, I have a question about the whole antique receiver tang/date thing. Since a M39 has, by definition, been modified from its original M91 configuration and the only thing on the rifle that is still "antique" is the receiver, doesn't it become a non antique on the date it was modified?

Receiver age is the governing factor. I love to shoot my 1897 M91 Finned Mosin, btw.

Most of the fins I have seen were pieced together like that. Not necessarily an indication of a duffel cut.

[onelonehorseman]

Most duffel cut I've seen were cut beneath the barrel band.

Yup, I've got a couple of antique M39s delivered straight to the door. Great rifles in excellent condition.

That cut below the front sight is the normal splice location. All of them have that.

No, it won't. It's not rated for that.

Modern 8mm Mauser is 8x57 ISS.

The "S" conversion was for the 150 grain IS load.

Modern 8mm Mauser is very dangerous to shoot in the M88.

Commercial, United States ammo is downloaded to 8x57JS pressures because of the existence of the M88.

Slight thread jack...but an actual thing for M39s!
Any of you guys ever able to get rid of the “frosted” look inside these barrels or do you leave it be after running some hot water down the barrel after a shoot and light oil?

[Josh Smith]

Try using a sonic cleaner first. That often removes a lot of "irremovable" stuff.

That said, I don't worry about it.

The reason corrosive ammo is corrosive is because salts form when the primer ignites.

These salts stay in the bore and attract water, causing rust problems.

It's not truly corrosive as is, say, black powder residue, which forms a weak sulfuric acid mix when moist.

Just get the salts out and oil the barrel.

I do recall reading about a cleaning method some third world country was using for their AKs: Knot a shoelace, dip in in motor oil, and pull through the barrel. Apparently it worked. Doesn't take much.

Josh
