History of the .455 Mark I to Mark VI Cartridges:
The .455 Revolver has many designations a/k/a .455 Revolver, .455 Webley, .455 Colt, .455 Enfield, .455 Eley, .455 Target with many various versions; Mark I, Mark II, Mark III, Mark IV, Mark V, Mark VI. We will try to explain them one at a time:
Introduced around 1891 to1897 as .445 Colt ,.455 Webley, and .445 Enfield Mark I, many purists would say they differ in loads and bullet weights, but to the best of my limited knowledge they are interchangeable and will work in the same revolver.
The bullet is .445″to.461″ in diameter, case rim diameter is .525″ -.535″, case length is .850″ to .886″, over-all cartridge length is 1.157″ to 1.448″.
This is where the Enfield and the others (Webley MK II or revolver MK II) differ:
A. In the Enfield Mark II there was a bullet change to softer lead and bees wax lubrication, but no case length change over the Mark I.
B. In the Webley Mark II or Revolver Mark II, they had a softer case, were tested and used from the early 1890s and reintroduced around 1914 to the British Army.
This cartridge was shorter than the Mark I due to the use of smokeless powders (Cordite) and the need for less powder and case volume to achieve the older black powder pressure.
Case length was reduced from .850″ to .886″ to .740″ -.760″ and a lead bullet.
The Webley Mark III was basically a high pressure load wad-cutter (blunt ended bullet) of the Webley Mark II and nicknamed “The Man Stopper” and was discontinued round 1902 due to over powered (recoil).
The Mark II and Mark III were basically being tested and used at the same time in history.
Cases were the same length as the Mark II but over-all cartridge length was shorter (.966″ to .968”) due to the short wad-cutter lead bullet.
This cartridge was adopted by the British Army in 1909. It was more powerful than the Mark II but less powerful than the over powered (recoil) of the Mark III. Lead Bullet.
This cartridge was adopted by the British Army in 1912; the only difference between the Mark IV and Mark V is the bullet alloy – harder in the Mark V. Lead Bullet.
This cartridge was adopted by the British Army and Air Force in 1939.
This was the first version to use jacketed bullets instead of the lead bullets in all the past versions.
It was used in Britain until 1946.
The .455 Colt and .455 Enfield were only produced in the longer Mark I length: case length was .850″ to .886.”
The over-all cartridge length is 1.157″ to 1.448″ and only loaded with black powder, although later in history.
They were loaded by commercial loaders with smokeless powder after the pistol was available to the public and loaded to black powder pressures .445 Webley a/k/a .445 Revolver, was loaded in Mark II, III, IV, V and VI and loaded in black power in Mark II and smokeless powder in Mark II, IV, V, and VI.
