Unknown 9x22R cartridge


#1

Could someone ID this cartridge? I think it some kind of czech cattle killer ctg, but i’m not 100% sure

Thanks in advance,
Vince

Vince - I don’t know what it is. The only comment I can make is that the very heavy 6-stab primer crimp seen on some Czech cartridges are usually on blanks and proof loads, rather than ball loads. I have examples of both, but don’t off hand (and I can say it is impoosible that I do) recall having any auto pistol load with this primer crimp other than proofs and blanks.

Might it be 9mm Japanese Revolver? I don’t have a round in that calibre to compare it to, but it looks like it would be close to it.


#4

All of those crimps imply some heavy pressure. The Japanese revolver wouldn’t need that.


#5

The rim seems too thick to be for the Japanese Revolver. M. Rea

There is nothing on that cartridge that says “Japanese 9mm Revolver.” The rim is way too thick - the 9mm Japanese round has one of the thinnest rims, I think, ever put on a Revolver round. The bullet ogive is wrong and even the primer cup looks wrong, not to mention the case finish or whatever that is. I have never seen a Japanese round with those six square crimps, which are absolutely typically Czech. The only ball rounds I have seen with similar crimping at the primer are the two variations of Cambodian 9mm I have, made at Stung Chral, and that factory and machinery was provided by the Czechs. All other Czech rounds I have with this crimping are blanks or proof loads.

It seems odd that they would crimp the blanks this way. Could they be reloaded proof cases ?

I believe there was some discussion, and a pic or two, of this round a few years ago in the IAA magazine. I’m not sure if it was resolved.
