This cartridge case is often found in Germany. Here is the way i clean them. (Tumbler would be the other)
1. Dowel
2. wooden or steel stick
drilling machine
3. Stick the cartridge to the dowel
4. During the drilling machine is running you can hold a sandpaper covering the cartridge.
5. Ready.
6. Before and after.
7. looks good
8.I used it to hold a german infantry medal (also a found of me).
P.S Germans are crazy. Use a glove to protect your hand. Not like i do.
