Abstract: A projectile includes an explosive charge, a corresponding initiating device, a penetrator that only deforms upon impact with a target having a predetermined mechanical resistance, an internal impact contactor arranged between the penetrator and the charge, and a device to ensure initiation of the charge following crushing of the internal impact contactor and after the explosive charge has begun to be deformed following impact on the target. The projectile is particularly effective against hard targets such as stone, brick or cement structures.

Abstract: A cartridge tube for a grenade capable of being fired by a live round of a weapon has a bullet trap to stop the bullet and a plug made of a deformable material to prevent the fragments produced when the bullet impacts on the bullet trap from escaping from the cartridge tube. The plug bears against a wall positioned between the plug and the bullet trap. The wall is attached to the cartridge tube and is substantially perpendicular to the center-line of the tube. The wall is positioned at a distance from the bullet trap along the center-line of the cartridge tube, thus establishing an empty space between the wall and the bullet trap.
