little collection of 9,3x64 cartridges: RWS, DWM, older Brennecke made by DWM, Barnaul lacquered steel case and brass plated steel case (yes, reloadable if you have 6,45mm berdan primer)

you see the TUG load was offered by everyone ever made it in germany

.373 versus 9,3x64
imho, the 9,3 is the better cartridge
