Any information about this one?
Got it from last meeting in aerzen, Germany.
Great find! According to Zwecker it was made by Sellier & Bellot, Prag.
Very nice cartridge, who made the guns for this caliber?
Fede and Lars,
Thanks for the reply!
I have no idea about who made the guns for these, but cannot think they made many of them, since the cartridge itself is not very often seen at all.
