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 ...
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 .450/400 2 3 ⁄ 8 inch Nitro Express was loaded with a 400 gr. RN bullet with 42 or 43 grains of cordite and was meant for use in newer rifles chambered for the .450/400 2 3 ⁄ 8 inch case as this loading generates greater pressure than the Black Powder Express versions of the cartridge.
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 ...
A 3 + 1 ⁄ 8-inch variant would later be loaded with cordite to become the .577/500 Nitro Express. [1] For some time the .577/500 No. 2 BPE was loaded with cordite to become the .577/500 No. 2 Nitro for Black, the same cartridge loaded with mild loadings of cordite, carefully balanced through trial to replicate the ballistics of the black ...
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 ]
The .600 Nitro Express is a slightly tapered walled, rimmed, centerfire rifle cartridge designed for use in single-shot and double rifles. [4]The cartridge fires a .620 in (15.7 mm) diameter, 900 gr (58 g) projectile with three powder loadings: the standard being 100 gr (6.5 g) of cordite at a muzzle velocity of 1,850 ft/s (560 m/s); a 110 gr (7.1 g) loading which generates a muzzle velocity ...
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.
