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 W.J. Jeffery & Co developed the .400 Jeffery NE from the .450/400 3-1 ⁄ 4-inch Nitro Express, following extraction problems with the latter cartridge.. The .450/400 3-1 ⁄ 4-inch NE was recreated by loading the old .450/400 3-1 ⁄ 4-inch Black Powder Express with cordite, transforming a low-velocity deerstalking cartridge into a genuine big-game hunting round capable of tackling even ...
The .450/400 Nitro Express is a Nitro Express rifle cartridge that is produced in three case lengths: 2 3 ⁄ 8-inches, 3 inches and 3 1 ⁄ 4-inches, [2] and is intended for use in single shot and double rifles. The 3-inch and 3 1 ⁄ 4-inch versions are considered classic Nitro Express cartridges.
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.
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).
Handgun propellants may reach peak pressure before the bullet leaves the cartridge case, while rifle propellants may move a bullet several inches before reaching peak pressure. [4]: 125 The motion and behavior characteristics of projectiles while under the influence of the gases produced by the propellant is known as internal ballistics. [13]
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).
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 ...
