Greetings,

I put my hand on boxed primed 357 Magnum cases with the following markings on the bottom: 357 Magnum nny (Cirrylic characters pi-pi-upsilon)

My question is simple : Are they good?

Another question not related: I am tumbling my cases with corn cobs and no shining agent. The cases are not very shiny but they are quite clean. Is it acceptable?

Thank you

It's Yugo or Chetz stuff, probably.

You might make sure it is Boxer primed, not Berdan, and beware of too small flash holes if it is Boxer.
Your decapping pin can get stuck and bend or break off.

Corncob Tumbling without polishing agent would seem like it would take forever!
While the result is probably perfectly acceptable, you could do it in a lot less time with some polish added.

Even a dash of Mothers Mag Wheel polish will get you by.

They are Yugoslavian: rvi Partizan-Namenska Proizvodnja, Titovo, Uzice 31000, Yugoslavia. These are actually Cyrillic letters equal to "PPU in the Western alphabet.

Hope this helps.

It's Prvi Partisan brass, made in Serbia, should be boxer primed. If it's like their other brass, should be good stuff.

You have it backwards 2 holes is Berdian, single hole is Boxer.

BTW I would not tumble with live primered cases with any polish agent added, it will probably kill the primer. I would clean them manually with some 0000 steel wool if you need to size them. If the bullet will hold and they mic within speck loadem' up and shoot them. I would clean the pistol immediately after firing JUST IN CASE the primers were corrosive. My 2 pennies

re-posting my answer posted on that other board:

The 357 brass is PPU (Prvi Partisan), a Serbian ammo maker in Yugoslavia. It's OK.
I had problems with PPU brass in 9mm, wrong primer pocket size. But not with their 357s - they seem to be as good as any other make.

Never mind the appearance of the brass after tumbling, if it's clean it's good to use.
