Thank you, Raimey! That is most helpful!

Where did you get the connection to Emil Eckoldt? Was that from another reference associated w these proof marks?

Interesting stuff about the Suhl proof facility.

One question about the acceptable bullets, you mentioned ‘just about any lead cast bullet for 9.3x72r” but since it was proofed with a copper jacketed bullet, I assume that would also still be fine today? I see they are available and I’d consider taking it out deer hunting for a late season doe if that’s the case.

Thank you again for such thorough information!
