Abstract: In modern anti-terrorism operations, rapidly entering the room often requires breaching doors. Door-breaking
projectiles can destroy locks or chains to facilitate this. However, traditional shotgun-fired door-breaking projectiles may cause
collateral damage with their steel shot and fragments. So, this paper presents a new LCD (low collateral damage) breaking
projectile. It uses an internally ribbed porous thin-walled non-metallic cylinder as the carrier and is filled with high-density
metal powder. This structure ensures stability during firing, boosting penetration. After breaching, the metal powder quickly
loses kinetic energy, reducing collateral damage. Ballistic tests and numerical simulations were done to study the breaching and
collateral damage of this new projectile on steel targets. The effects of powder material, initial kinetic energy, and internal ribs
were examined. The penetration and energy-absorption mechanisms of the porous cylinder with metal powder were analyzed.
Results showed that a 2-order ribbed breaking projectile needs less initial kinetic energy and causes non-lethal collateral

damage. This projectile, with its internal support, maintains stability during firing, enhancing penetration. After breaching, the
