Today I have what I believe to be a .38 rimfire casing without a headstamp. According to what I read on Wikipedia's ".38 rimfire" article and some other random stuff online, this casing dates back to the latter half of the 1860s (when the round was developed) to the 1880s or so, when headstamps and centerfire ammunition became the norm. Is that correct? I also read on wikipedia that the .38 rimfire was used by the US military. If so, what weapons did the US military use that required this type of ammunition?
