When the projectile leaves the gun the pressure in the barrel drops and the gas stored in the reservoir flows back into the barrel. By aiming these holes forward, this flow gives the propellant gasses in the barrel enough forward momentum to draw them out of the barrel. [2] Various designs attempt to improve on the basic concept in a number of ...
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]
A combustion light-gas gun (CLGG) is a projectile weapon that utilizes the explosive force of low molecular-weight combustible gases, such as hydrogen mixed with oxygen, as propellant. When the gases are ignited, they burn, expand and propel the projectile out of the barrel with higher efficiency relative to solid propellant and have achieved ...
Walmart Inc said it would discontinue sales of some ammunition in stores across the U.S., in response to the recent mass shootings in Texas. Walmart to stop selling short-barrel rifle ammunition ...

Obturation is the necessary barrel blockage or fit in a firearm or airgun created by a deformed soft projectile. [1] A bullet or pellet made of soft material and often with a concave base will flare under the heat and pressure of firing, filling the bore and engaging the barrel's rifling.

A squib load (also squib round, squib, squib fire, insufficient discharge, incomplete discharge) is an extremely dangerous malfunction that happens when a fired projectile does not carry enough force and becomes stuck in the gun barrel instead of exiting it. In the case of semi-automatic or automatic weapons, this can cause subsequent rounds to ...
