What was the first rimfire cartridge? My very limited records say a patent from 1831 describes a rimfire cartridge, which I take to also mean a rimmed one, which brings me to my next question. What was the first rimmed cartridge? Was it the patent? If not, I believe the answer would be the .22 BB Cap.
in the United States it was the S&W #1 which would be a 22 short. In Europe the rimfire was much more developed.
I just meant in general everywhere.
