.22 pinfire derringer project

[Busyhands94]

hello guys, i recently had an idea for a .22 caliber pinfire single shot pistol. i am aware that no manufacturer today produces a .22 pinfire cartridge due to the invention of modern cartridges and modern primers. i know that building one is probably the most unnecessary project i have come up with, however i would like to build my own pinfire gun for fun really. that and the fact that NOBODY at the firing range will have a .22 pinfire but me. what i will have shall be completely unique! now the ammunition is not exactly available at your local Wallmart in packs of 500, but i plan on making my own .22 pinfire out of spent casings loaded with 4F black powder. i know this is a completely strange idea and is not exactly the most practical or powerful firearm, however i would like to build one just for kicks. i already own a 2mm pinfire Berloque pistol, and i find the little thing to be rather cool. i find pinfire guns and ammunition to be a rather fascinating part of history, so i think building one would be a fun little project! i am thinking about making it break action just like my 2mm pinfire, however several action ideas are being considered.

change the caliber to .32, and you are good to go. reloadable, too.

i think that .32 would be too big for my tastes. i am planning to use it as a parlor pistol actually, however shooting .32s in my indoor firing range is kinda risky, i can hardly get away with a .22 cap n' ball, not to mention that my bullet trap probably could not stop one. but i think .22 should be just fine as a parlor load. besides, how many people do you know that can honestly say "I own a pinfire .22 and shoot it often" i would like to have a gun that is in a totally unique caliber, that would be really really, cool!

44 Henry i plan on drilling a small hole in the case, putting a percussion cap into the case with the opening facing the hole, and inserting a small piece of hardened steel wire as the pin. i found a diagram online of how pinfire cartridges work. it seems simple enough! i also reload the 2mm pinfire cartridges for my berloque pistol, i basically fill the case with liquid priming compound and let it harden. i might do that with these if i cannot get the percussion cap idea to work. and of course David, i will post pictures! i am considering building a .22 falling block rifle with an exposed hammer, i might make it so i can fire .22 pinfire ammo out of it with a separate hammer that is specifically designed for pinfire use, however the gun will also be capable of firing standard .22 rimfire ammunition.
