"According to "Cartridges of the World," the .41 Rimfire consisted of a 130 grain (8.4 g) lead bullet propelled by 13 grains (0.8 g) of black powder in its original load. The round produced a muzzle velocity of 425 feet per second (130 m/s) and a muzzle energy of 52 foot-pounds force (71 J). In contrast, modern low-powered smokeless cartridges produce considerably more energy: .380 ACP (200 ft·lbf), .
22 LR (100 ft·lbf)."

425 fps. Airsoft weapons do that.
