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 ...
Firstly, cordite was not readily available except sealed in ammunition which was controlled issue. To remove the bullet from a .303 cartridge requires a minimum of 60 pounds pull with very little to grip on. Cordite is a very hard materiel and not easily chewed.(I have tried) and is almost totally insoluble in water (and hence body fluids).
The .577/450 Martini–Henry is a rimmed, bottlenecked centerfire rifle cartridge derived from the .577 Snider, it was lengthened and bottlenecked. The .577/450 Martini–Henry was developed for use in the single shot Martini–Henry service rifle, originally loaded with blackpowder but later used cordite propellant.
The .450/400 Black Powder Express cartridges are bottlenecked centerfire black powder express rifle cartridges produced in two case lengths, 2 3 ⁄ 8 inches (60.3 mm) and 3 1 ⁄ 4 inches (83 mm). Both cartridges were later loaded as "Nitro for Black" cartridges, the same cartridges loaded with mild loadings of cordite carefully balanced ...
The .400 Purdey is a rimmed straight walled centerfire rifle cartridge intended for use in single shot and double rifles.It fires a bullet of .405 inches (10.3 mm) diameter weighing 230 grains (15 g), driven by 47 grains (3.0 g) of cordite, at a listed speed of 2,050 feet per second (620 m/s).
The term "Express" was coined by James Purdey in 1856, derived from the express train, to publicise the bullet velocity of his double rifles and became common parlance for many rifle cartridges. The addition of the word "Nitro" stemmed from the propellant used in these cartridges, cordite, which is composed of nitrocellulose and nitroglycerine.
The .500/450 Magnum BPE was created by necking down the .500 Black Powder Express to .45-inches. [2]For some time after the turn of the century, the .500/450 Magnum BPE was loaded with cordite to become the .500/450 Magnum Nitro for Black, the same cartridge loaded with mild loadings of cordite, carefully balanced through trial to replicate the ballistics of the Black powder version.
This cartridge was originally loaded with 90-grain (5.8 g) of cordite and 525-grain (34.0 g) bullet at 2,300 ft/s (700 m/s) for 6,166 ft⋅lbf (8,360 J) of kinetic energy. [2] While the .505 Gibbs has a greater case capacity than most modern cartridges, it is loaded to lower pressures. [ 2 ]
