Probably a 44 Bull Dog. "Cartridges of the World" (Barnes) shows a sketch of the cartridge base with the "44 B.D." and "W.R.A. Co" as headstamp text. Dimensions are in the ballpark, per Barnes. The drawing appears to show an outside-lubricated lead bullet. Bullet diameter is given as .440".

Barnes states that British Webley and American Harrington & Richardson revolvers chambered it, starting roughly 1880. USA manufacture of the ammo ended about 1938-39. Ballistics were a 170 grain bullet at 460 FPS, for about 80 ft./lbs. of energy. That would raise quite a welt.
