J-P: That is an interesting box! What caliber does “Cartouche Federale” actually represent? That sounds almost like a Swiss designation.
on the box it is written (just between the two parts Martini)
and they say cartouche annulaire (rim fire)
therefore I think it is the 41 Swiss RF
Is Martini on the label referring to the Martini rifle??
I have the same full boxl.
Here is a cartridge from this box :
and the rifle that used it :
Thanks, Chassepot. Great headstamp, and I see the rifle does use a Martini action.
