I have always been fascinated with the pinfire cartridge design. The concept of having a separate firing pin in each cartridge may have made sense at the time, but seems ludicrous in hindsight.

I was surprised to learn than a French firm, H&R, manufacture pinfire components and reloading kits.

Twelves pieces of 9mm pinfire cases, each usable twice, will set you back 119 EUR ($145)!
