the only one I know for sale are this HWM rounds made in the early 1990s for 20 euro a cartridge.

dont know just now if this are dummys or loaded cartridges but suspect dummy rounds made from the components. if you wish to have one or more I can probably help you. dummys would be better to ship today no doubt about it.

there were never standards or CIP measurments for this round! I have look what ever was possible and dont find anything.
