The oldest gun propellant was black powder, a low explosive made from a mixture of sulfur, charcoal, and potassium nitrate. It was invented in China during the 9th century as one of Four Great Inventions , and still remains in occasional use as a solid propellant for antique firearms .
The Cobray Company was an American developer and manufacturer of submachine guns, automatic carbines, handguns, shotguns, and non-lethal 37 mm launchers. These were manufactured by SWD. In the 1970s and 1980s, Cobray was a counter terrorist training center in addition to being an arms maker under the leadership of Mitch WerBell. [1]
Gunshot residue from a pistol shot. Gunshot residue (GSR), also known as cartridge discharge residue (CDR), gunfire residue (GFR), or firearm discharge residue (FDR), consists of all of the particles that are expelled from the muzzle of a gun following the discharge of a bullet.
For handgun cartridges, with heavy bullets and light powder charges (a 9×19mm, for example, might use 5 grains (320 mg) of powder, and a 115 grains (7.5 g) bullet), the powder recoil is not a significant force; for a rifle cartridge (a .22-250 Remington, using 40 grains (2.6 g) of powder and a 40 grains (2.6 g) bullet), the powder can be the ...
Other situations where a single shot stops an attacker are most likely psychologically based. The attacker may be surprised that their subject is armed, and could flee without ever being struck. Alternatively, an attacker may be frightened after being shot and decides to disengage rather than press the assault.
Squib rounds are possible in all firearms. They are most often caused by negligence in the powder loading process (insufficient or no powder load), or a failure of the primer to ignite the powder at all. In the case of no gunpowder in the cartridge, the primer, when struck, produces just enough force to push the bullet into the barrel but no ...
Finnish smokeless powder. Smokeless powder is a type of propellant used in firearms and artillery that produces less smoke and less fouling when fired compared to black powder. Because of their similar use, both the original black powder formulation and the smokeless propellant which replaced it are commonly described as gunpowder.
As with their air-actuated cousins, powder-actuated guns have a muzzle safety interlock. If the muzzle is not pressed against a surface with sufficient force, the firing pin is blocked and cannot reach the load to fire it. This helps ensure that the gun does not discharge in an unsafe manner, causing the nail to become an unrestrained projectile.
