A dual-purpose bullet is provided consisting of a thermoplastic body, a base cap, and a pressed powder core. The bullet in the preferred embodiment can either penetrate destroying and disrupting large volumes of human tissue or not penetrate the human tissue delivering a strong shock event and creating a thermal nuisance. The lethal mode is achieved by a high-velocity launch of the bullet without ignition of the igniter mixture and pressed powder core. The less-than-lethal mode is achieved by a low-velocity launch with ignition of first the pressed powder core and softening of the plastic projectile body.
