.455 Webley Ammo For Sale- Top Ammo Vendors Available
.455 Webley is a British handgun cartridge, most commonly used in the Webley top break revolvers Marks I through VI. It is also known as .455 Eley and .455 Colt.
The .455 cartridge was a service revolver cartridge, featuring a rimmed cartridge firing a .45 bullet at the relatively low velocity of 650 ft/s (190 m/s). The result was a cartridge and handgun combination with relatively mild recoil. The .455 was rated superior to the .45 Colt in stopping power in the disputed United States Thompson-LaGarde Tests of 1904 that resulted in the adoption by the U.S. of the .45 ACP cartridge.
The .455 Webley cartridge remained in service with British and Commonwealth forces until the end of the Second World War.
