History
Introduced for the Remington Navy single-shot, rolling block pistol in 1865, the low-velocity round loaded a 290 gr (19 g; 0.66 oz) bullet over 23 gr (1.5 g; 0.053 oz) of black powder.[1]
The rimfire version was replaced in 1866 by a centerfire equivalent. A Boxer-primed version remained commercially available until World War I.[1]
The power of the .50 Remington was less than average, but the heavy bullet, even at comparatively low velocity, made it "a rather potent handgun round".[1]
