First here are some pinfire shotshell reloadable primers + pins by SFM
I used kind of a new technique with some of these pictures. This is actually 26 pictures combined into one. Each picture has a different part in focus to get extreme detail on such a magnified image. This box is less than an inch wide! Look at a close up of the pins here in a higher resolution version: Larger
Then some of just the reloadable primers to use with the previous pictured pins. They are all different from each other. Notice the symbols between the words on the lid vary on each one as well as the font
A neat 12mm Rifle cartridge I guess? Any idea who made it and what the “T” means?
