Abstract
Nonlethal cartridges adapted to be chambered in a firearm having a barrel that includes rifling are provided. In one example, the cartridge includes a cartridge case and a sabot that is telescopically coupled to the cartridge case and that has a sabot mouth. A projectile includes a polymer base projectile portion disposed in the sabot mouth. A polymer front shell projectile portion is coupled to the polymer base projectile portion and has an outer surface that includes a circular locking rib feature that forms an interference fit with the sabot mouth. The polymer base projectile portion is configured to engage the rifling of the barrel to impart spin stabilization to the nonlethal projectile when propelled from the sabot in response to the expansion of a propellant gas.
