Abstract:
A combination of a gun having a barrel and propellant means for launching a projectile from the barrel; and a non-lethal projectile;characterised in that the non-lethal projectile comprises a hollow spherical outer casing formed from a resiliently deformable material, and a plurality of substantially spherical balls within the casing, the spherical outer casing being deformed as it travels along the gun barrel under pressure from the propellant means but being sufficiently resilient to resile to a substantially undeformed state upon leaving the gun barrel, wherein the substantially spherical balls are formed from a material having a density greater than the resiliently deformable material from which the spherical outer casing is formed, and said spherical balls have a maximum diameter in the range from 2 mm to 10 mm, a minimum density equivalent to a specific gravity of 7.0, and a minimum Rockwell hardness of 90.5, and wherein the plurality of substantially spherical balls have surfaces that are smooth so as to allow one ball to slide readily over the surface of another.
