A projectile with a penetrator, which on impact with an obstacle (wall, door, glass pane etc.) pierces it, so that immediately afterwards an active substance which is carried along by the penetrator, is set free behind said obstacle. Such a projectile is of particular use by special police, military or other operations as a so called barricade-penetrator, in order to set out of action persons to be overpowered in closed rooms. The release of the active substance occurs without a pyrotechnic detonation; the active substance is expelled exclusively through mechanical means, and preferably by a piston action resulting when the projectile contacts the obstacle.
