I located brass with the correct markings for the various M/S cartridges.
6.5x54 M/S Norma
8x56 M/S Horneber
9x56 M/S Horneber
9.5x556/57 Horneber
Other than the Norma offering, these are SPENDY.
I am starting to convert 8x57 Mauser brass (good quality brass) into the various M/S sizes. Configurations will be exact, but the name will not be.
I will post pictures as I go along.
I mentioned in a Double Gun post that I and a few others are working hard to do all the R&D to bring various cartridges back to their niche markets for just enough to live on ourselves. I have located sources of the correct bullets for the various (and variable) bore sizes. I read this column with keen interest, and hope to be able to import some "Perfect" ammunition, as well as some "Perfectly shoot-able and hunt-able" ammunition.
