Hello to all.
I have a project I am trying to complete, but I need a shell. I want to make one cartridge for an old 11MM Murata. I need to fire-form a shell so I can get expanded dimensions of this chamber to make a set of dies from. I can cast it too, but I like to have both the fire-formed shell and a casting.

Can anyone out there donate a shell to me? Or let me buy one?
