The line of improved military rifle powder came into existence in the 1920s. It consisted of nitrocellulose, dinitrotoluene (DNT), graphite, and a small amount (0.6%) of diphenylamine (stabilizer). Potassium sulfate is added to decrease the amount of muzzle flash. Cartridges loaded with this powder include .30-06 Springfield and 7.92×57mm ...
Burst barrel of a muzzle loader pistol replica, which was loaded with nitrocellulose powder instead of black powder and could not withstand the higher pressures of the modern propellant The development of smokeless powders, such as cordite , in the late 19th century created the need for a spark-sensitive priming charge , such as gunpowder.
[3]: 287–289 Nitrocellulose produces greater volumes of gas per volume of solid than black powder does, so nitrocellulose bulk powders were less dense than later smokeless powders. Nitrocellulose bulk powders designed for early straight-sided black powder rifle cartridges like the .32-40 and .38-55 were friable and easily crumbled. The ...
Development began in 1864 to replace the RBL 6-pounder 2.5-inch (64 mm) gun of 3 long hundredweight (340 lb; 150 kg), which had proved too heavy for a mountain gun. . Several Mks of 7-pounder RML of 2 long hundredweight (220 lb; 100 kg) were tried in 1865 by boring out and rifling old SBML bronze guns, but were still too
Military rifle propellant was manufactured in batches in a procedure taking about two weeks [7] from treating cotton linters with nitric acid, through curing the extruded grains to evaporate excess ether and alcohol, and finally coating the dried grains with DNT and graphite. Each batch had somewhat different reaction rates, so testing was ...
The 7 in (18 cm) referred to, and introduced into the service in 1865, were the first of the so-called Woolwich guns, which then meant "wrought iron M.L. guns built up on Sir W. Armstrong's principle, improved upon by hooking the coils over one another, and having solid ended steel barrels, rifled on the system shown above, for studded ...
The 100-pounder (sic) as a pivot gun is superior to the 95 cwt. solid 8-inch gun; but as broadside guns between decks we do not like them; the smoke is too great. Rear choke carriages with such heavy guns are very slow in working and the decks dreadfully cut up. The common shell is one of its great efficiencies, the bursting charge is so great ...
