Firearms (English: firearm) are weapons that release one or more projectiles that are driven at high speed by the gas produced by the burning of a propellant. This fast burning process is technically called deflagration. Firearms used to use black powder as propellant, while modern firearms now use non-smoking, cordite, or other propellant powders. Most modern firearms use a circular barrel to give a rotating effect on the projectile to increase the stability of the trajectory.
