The basics of the self-contained center-fire cartridge
has changed little since 1870.
By history, I mean it was the first center-fire cartridge
chambered in the Colt SAA when adopted by the US Army in 1873.

firing revolver was the Smith & Wesson #3 American, which was chambered in .44 Smith & Wesson as well as .44 Rimfire to mate up with the Henry rifle.
Being as how Smith & Wesson was more interested in selling revolvers to the US Army than to civilians, they perked up when the government told them to go back to the drawing boards and present them with a center-fire cartridge
. This they did, at first calling it the .44/100 and the Army reciprocated by buying 1,000 of their Model No.
