7.62x25

7.62x25 h/s 10 54 Arsenal, Kazanlak (previously named Durjava Voenna Fabrika), Bulgaria???

Yes, 1954 production.

Thanks Jonny! Also, did they fire 7.63 Mauser rounds in the Tokarev?

Probably. No problem using 7.63 Mauser in-place of Tokarev, but it is widely warned not to do the opposite.

Yes that’s what I had heard also.

Thanks!
Steve
