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.
