The 11mm French Ordnance is a rimmed black powder cartridge intended for the 11 mm MAS 1873-1874 revolver in service with the French Army.^[1] The velocity and power of the first variant, equivalent to the .25 ACP at just 74 ft/lbs of energy, was weak even for its time. The second variant, 1873–1890, corresponded in power to the .32 ACP with 140 ft/lbs of energy.
