Hijacking this thread, but what is the 10,2mm X 60 cartridge in the lovely longarm below?

At that late date, my first thought was a .405 Winchester but that is too long. Next would be the 450/400 2 3/8 NE but its 400 grain bullet is heavier than the 355 proof bullet. So, what else comes to mind?

My thoughts exactly but after that I am blank??

Dixon has a 10,2X60R Mannlicher a.k.a 10,10X59.8R but I would say that is a longshot with a limb in the way??

Too, I think it was made between 1912 & WWI.

Wolfgang found that in 1902 that a law was passed in Switzerland(Graubünden) that was designed to omit military cartridge from hunting. The law put a minimum at 10,2mm so the 10,3X60R was developed as a stop-gap measure to fill the void.

Unless it is an older Austrian chambering??

Of the other 2 tubesets composing the set of 3, I do not see any marks that puts it Post WWI.


3 Ringe Weapons Grade Steel was of course made @ Sauer.




The other set was sourced from the „Schilling-Schmiede“.
