Non-lethal ammunition for a riot gun includes a forwardly open casing, a projectile mountable in and dischargeable from the casing, a propellant cartridge extending into the casing interior, and a UV curable adhesive disposed in sealing relation about the propellant to effectuate uniform firing of the projectile. The projectile includes rearward and forward end portions each provided with a central cavity with the rearward cavity enclosing the cartridge, a weight in the forward cavity for balancing and increasing the mass of the projectile, and a subassembly carrying in a nose thereof a chemical payload or chemical agent, the subassembly including a stem sized for interference fitment within the forward cavity to secure the subassembly to the projectile and having a chamber for positioning the weight in the forward cavity.

What is claimed is: 1. A non-lethal ammunition projectile, comprising: a projectile body removably emplaceable within a shell casing, the body including a forward leg having a forward end portion for mounting a payload, a rearward leg having a first chamber for receiving a propellant, and a medial collar exteriorly configured for sealing engagement with the casing wall when the projectile is in the casing, the forward end portion defining a second chamber and having an interior wall, and the forward end portion, the legs, and the collar being generally cylindrical and concentrically disposed along a central longitudinal axis, a mass disposed within the forward end portion for balancing the projectile and inhibiting tumbling of the projectile in flight, and a payload subassembly removably emplaceable within the forward end portion, the payload subassembly comprising a closure member of resilient material, a nose member, and a payload, the closure member including a stem sized to frictionally engage the interior wall of the forward end portion and having a third chamber to receive the mass whereby to position the mass along the central longitudinal axis, and a cylindrical cap sized to close the forward end of said second chamber, and said nose member being dome-like and connectible in an interference fit to the cap whereby to form a fourth chamber within which the payload is received. 2. The ammunition as claimed in claim 1, wherein the nose includes an annular surface of a diameter slightly less than the outer diameter of said cylindrical cap, wherein the nose is frictionally secured to the cap. 3. The ammunition as claimed in claim 1, wherein the nose is comprised of a compliant material that resists deformation during flight but is readily breached upon impact whereby to disperse the payload around the point of impact. 4. The ammunition as claimed in claim 3, wherein the nose is comprised of Styrofoam. 5. The ammunition as claimed in claim 1, wherein the closure member is comprised of foam rubber. 6. The ammunition as claimed in claim 1, further comprising: a cylindrical band fitted about the exterior of the forward end portion, the band having an interior surface and a contoured exterior surface for guiding the projectile in the air, and at least one mating protuberance and depression operating, respectively, between the interior surface of the band and the outer exterior surface of the forward end portion to resist relative rotation therebetween. 7. The ammunition as claimed in claim 6, wherein the protuberance extends radially outwardly from the outer exterior surface of the forward end portion and the depression extends into the interior surface of the cylindrical band, whereby to prevent relative rotation therebetween. 8. The ammunition as claimed in claim 6, wherein the protuberance extends radially inwardly from interior surface of the cylindrical band and the depression extends inwardly of the exterior surface of the forward end portion, whereby to prevent relative rotation therebetween. 9. The ammunition as claimed in claim 6 wherein the protuberance and depression are axially elongated. 10. The ammunition as claimed in claim 6, wherein the cylindrical band is comprised of a resilient deformable material, the protuberance and depression are generally hemispherically shaped, coaxial insertion of the cylindrical band about the forward end portion operating bring the protuberance into engagement with and force the band outwardly until seating fitment of the protuberance within the depression. 11. The ammunition as claimed in claim 1, further comprising: a cylindrical band fitted about the exterior of the forward end portion, the band forming a contoured exterior surface for guiding the projectile in the air, said band comprising first and second cylindrical ring portions each having a cutout along an end face thereof, the end faces being abutted and the cutouts brought into registry whereby to form an aperture, and at least one mating protuberance extending radially outwardly from the forward end portion for fitment within the aperture to resist relative rotation therebetween. 12. The ammunition as claimed in claim 11, wherein said ring portions are comprised of a flexible elastomeric material. 13. A universal projectile ammunition, comprising: a shell casing having a primer and propellant receiving end, a central casing wall defining a central chamber, and a payload expelling end, a projectile body within the casing having a first leg disposed proximate to the primer end, a second leg proximate to the expelling end, and a medial closure collar which seals the central chamber, the first leg having a detonation chamber therein, and the second leg defined by a cylindrical wall having at least one longitudinally extending rib thereon and forming a central cavity, a cartridge containing propellant extending into the propellant receiving end and into enclosed relation with the detonation chamber, the propellant and the expelling end of the cartridge being sealed by a sealant adhesive comprising a mixture of an ultraviolet light curable acrylate composition and a photo-initiator, a cylindrical sleeve mounted onto the second leg, the sleeve having at least one longitudinally extending axial cavity therein, the axial cavity receiving the rib therein, a resilient closure cap having a stem frictionally engaged with the wall of the central cavity and a cylindrical cap disposed in closing relation with the central cavity, a mass retained within a central recess of the stem and positioned proximate to the central collar, a dome-shaped nose of resilient material frictionally engaged with the outer circumference of the cylindrical cap, whereby to form a chamber within which the payload is disposed. 14. The ammunition as claimed in claim 13, wherein the acrylate comprises a mixture consisting essentially of aliphatic urethane acrylate oligomer, high bonding acrylate hydroxyalkyl methacrylate, the sealant further comprising a silica filler photo-initiator. 15. The ammunition as claimed in claim 14, wherein the closure cap, mass, dome shaped nose, and payload comprise a subassembly that is assembled to the projectile body.
