Gat a good casting of the chamber, a solid steel knockout rod makes a big difference.
The chamber casting shows that it is a 9.3 Sauer.
9.3 Sauer are almost impossible to come by so that it is inpractial to think I can find a few to reload.
I spoke to an old German gunsmith yesterday and he told me that many of the 9.3x72R Sauers were "normalized" to the standard 9.3x72R in the old country.
I don't think that opening up the chamber to standard is going to "reck a good gun". It seems to me that it is the best option, all things considered.
