Has anybody formed cases successfully for an 8mm Nambu? If you have can you give me some ideas? A friend of mine showed me a very nice Nambu pistol his grandfather got overseas before world war two. It is in very nice unworn condition. He said that his grandfather had ammo for it also and they fired it a few times back around 1960. After receiving it, he hasn't seen any ammo for sale for it, and now reloads for a hobby.
