Abstract:
1. A less-lethal shot gun round comprising: a generally elongate tubular hull having a forward end and an opposed rearward end, said hull including a roll crimp at said forward end thereof; a base enclosing said rearward end of said hull; a propellant contained within said base; a wad sealably positioned in said hull adjacent said rearward end; a penetration-resistant kinetic energy projectile carried in said hull, said projectile being a generally cylindrical member having an outer cylindrical wall, said projectile having a rearward end and a forward end with a hollow cylindrical bore extending into said rearward end of said projectile and further including a convex solid head at said forward end of said projectile, such that the center of mass of said projectile is closer to said forward end of said projectile than to said rearward end of said projectile, thereby increasing the weight of said projectile at said forward end of said projectile, said forward end of said projectile defining a rim about said convex solid head; and said rim supporting said roll crimp and configured to open said roll crimp upon firing, said projectile being formed of a homogeneous non-metallic material having a durometer hardness of between about 20 and 90, said durometer hardness being less than that of conventional shot gun projectile materials.
