The .442 Webley (also known as the ".442 Revolver Centre Fire" in Great Britain, the "10.5x17mmR" or ".442 Kurz" in Europe, and ".44 Webley" or ".442 R.I.C." in the United States) is a British centrefire revolver cartridge. A black powder round, the .442 originally used a 15-19 gr (0.972-1.23 g) charge behind a 200-220 gr (13-14.3 g) bullet. This loading was later joined by a smokeless variety. Smokeless .442 Webley loads continued to be commercially offered in the U.S. until 1940 and in the United Kingdom and Europe until the 1950s.
