I guess velocity was not the .44/40's strong suit.No, but it sure has knock-down power, and with proper sights it'll reach out there a surprising distance. I don't know what it was exactly, but the gun Tom Selleck carried in Quigley Down Under looked like it might have been a 44/40. More likely a .50, though.
The Henry rifle was manufactured in 1860-61. The rimfire cartridge was pathetic in that it had a 200 grain bullet and only 26-28 grains of powder. The Quigley rifle, if I remember, is a 45 caliber with 120 grains of powder.
