Cordite was used initially in the .303 British, Mark I and II, standard rifle cartridge between 1891 and 1915. [ not verified in body ] Shortages of cordite in World War I led to the creation of the "Devil's Porridge" munitions factory ( HM Factory, Gretna ) on the English–Scottish border, which produced around 800 tonnes of cordite per week.
The initial .303 Mark I and Mk II service cartridges used a 215-grain (13.9 g), round-nosed, copper-nickel full metal jacketed bullet with a lead core. After tests determined that the service bullet had too thin a jacket when used with cordite, the Mk II bullet was introduced, with a flat base and thicker copper-nickel jacket. [12]
Cordite was a new form of explosive which had only come into use a few years before 1895, and the Army was in the process of equipping with it. In the Army Estimates for 1895, Secretary of State for War Henry Campbell-Bannerman reported that new barrels for the Army's .303 rifles which were suitable for cordite bullets were being fitted, but that "it is unnecessary at present to provide for ...
Following the introduction of a cordite rifle cartridge, the Cartridge S.A. Ball Martini Henry Carbine Solid Case Cordite Mark I was introduced in 1903. It was propelled by 34 gr (2.2 g) of cordite, the other major difference was a green paper used to patch the bullet [10] [11]
Originally (from 1889) Martini–Henry conversions used Metford rifled barrels (and were known as Martini–Metford rifles), which were more than suitable for the first .303 cartridges, which used black powder as a propellant but wore out very quickly when fired with cordite/nitrocellulose cartridges (introduced in 1895). In 1895, the Enfield ...
It entered British service in 1891 as Cordite Mark 1. Its main composition was 58% nitroglycerine, 37% guncotton and 3% mineral jelly. A modified version, Cordite MD, entered service in 1901, with the guncotton percentage increased to 65% and nitroglycerine reduced to 30%. This change reduced the combustion temperature and hence erosion and ...
in "igniter pads" at the ends of cordite cartridges to facilitate ignition; as the delay mechanism in time fuzes for artillery; in vent tubes for firing guns. British gunpowder designations were : [17] E.X.E.: "extra experimental": propellant: mixture of 2 ⁄ 3 brown and 1 ⁄ 3 black powders, used with BL 6 inch guns Mk III, IV & VI
The cost of working it from September 1916 to September 1918 was £12,769,000, during which time it produced cordite valued at £15,000,000, though it was claimed that without it the cordite would have had to be imported from the USA at a cost of £23,600,000. [1]
