Ammunition cartridge comprising a rigid casing including a tubular sleeve and a base closing an end of the casing, a projectile mounted at another end of the casing, a propellant charge contained inside the casing, and an ignition device. The projectile comprises a solid material body having a volume V1 extending between a tip to a trailing end, wherein the projectile further comprises a cavity that extends into the body from the trailing end, a volume V2 of the cavity being at least fifteen percent (15%) of a combined volume V1+V2 of the projectile solid material and cavity: V2>0.15×(V1+V2).

Haptic feedback system that simulates a detonation or explosive event. The system includes a power supply, an energy storage circuit, a switching circuit, and a conductor operatively connected to said energy storage circuit through said switching circuit whereby said conductor causes a haptic event when said energy storage circuit is electrically connected to said conductor by operation of said switching circuit. The system creates shock waves and pressure waves in a safe manner for use in a simulator.
