Abstract
A method to attenuate the blast wave/blast overpressure from a weapon discharge by leaking an effective quantity of propellant gas from behind the projectile, into the precursor gas flow in front of the projectile, while the projectile is still in the weapon barrel—whereby the exit pressure ratio of the projectile from the weapon is surprisingly reduced by about 95%—resulting in a reduction of from about 51.6 to about 58.2% in the peak pressure level/sound wave which impacts the user or crew of the weapon.
