Its a pin fire cartridge obsolete short lived inovation by a french inventorpatented I think about 1830 - 1835 ?
Used mosly in revolvers up until the 1835 -60 Made obsolete by the rim fire cartridge in the early 1860s
I beleive they were one of the first fully functional cartridges that contained percussion cap powder and shot in a single preloaded package. They were breach loaded instead of muzzle loaded. The pin on the side of the cartridge was struck to ignite the powder.
