A training ammunition cartridge comprises a projectile and a cartridge case with a pyrotechnic propellant. The projectile has a projectile body with at least one compartment therein forming a void and containing a material that transitions from a solid to a liquid after set-back and after exiting from a barrel of a gun. The void is of such configuration as to cause the liquid material therein to induce forces and moments that, after a period of stable ballistic flight, destabilize the projectile and shorten its flight. Alternatively, the projectile void contains a solid mass that is released to shift its position after set-back and after the projectile exits from the barrel of the gun, wherein the void is of such configuration as to cause the mass, upon shifting, to induce forces and moments that, after a period of stable ballistic flight, destabilize the projectile and shorten its flight.
