The poorly ignited charge moved the projectile partially down the tube, increasing the surface area of the propellant. The increased surface area of the propellant then ignited in the tube, raising pressures in parts of the gun not designed for them. The large overpressure caused "catastrophic tube failure" (an explosion destroying the gun tube ...

Number 4831 was used to load navy anti-aircraft machine gun ammunition, and number 4895 was used to load United States service rifle ammunition. As these propellants became military surplus after the war, large quantities of different batches were blended together to make products with uniform average performance for sale to civilians.
Firearms using gunpowder could be loaded using a small scoop or charge cup to determine the correct amount for each shot. Some early smokeless propellants called bulk propellants were designed for a similar volume and reaction rate as gunpowder, but most modern smokeless powders have improved efficiency offering more energy from smaller charges.

Oil prices will fall to an average of $65 per barrel in 2025 amid an oversupply of crude and a backdrop of slowing demand as countries shift toward cleaner energies and forms of transportation ...
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 .
