Non-lethal cartridge with spin-stabilized projectile

A non-lethal weapon system, comprising:

• a projectile comprising:
• a spin-stabilized, hollow, cylindrical projectile body open at the rear end and closed at the forward end, having a solid, flat forward face and a tubular bore-riding sidewall extending rearwardly from the forward face;
• a rotating band extending circumferentially about the sidewall;
• an undercut extending radially inwardly from an outer surface of the sidewall;
• a nose affixed to the flat forward face of the projectile body, the nose comprising a compliant material, rounded to reduce air resistance during flight and is of such a stiffness that the air pressure acting on it during flight will not substantially alter its original shape;
• a housing connected to the projectile body comprising a lip engaging the undercut of the projectile body;
• and
• a propulsion system disposed in an opening in the housing, the propulsion system comprising a cartridge case, propellant disposed in the cartridge case and a primer for igniting the propellant;
• wherein the propulsion system further comprises:
• an outer sleeve into which the cartridge case is inserted, the outer sleeve defining a vent hole at a nose end of the outer sleeve;
• and
• a diaphragm which covers the vent hole at the nose end of the outer sleeve;
• and means for launching the non lethal weapon cartridge, the means for launching including a rifled weapon tube wherein an inside diameter of the rifled weapon tube is substantially the same as an outside diameter of the bore-riding sidewall.
