Abstract
An industrial cartridge has a case that contains a propellant charge of at least two successively arranged propellant charge powders deflagrating at differing speeds. The powders are separated from each other by a gas-permeable cover extending transversely to the case axis. The case of the cartridge contains a compressible seal at the opposite end to the base end of the case. An ignition-transmitting tube is axially arranged in the case. The tube includes, at the level of the second and/or last propellant charge powder as seen from the base, a cover which is thinner than the wall of the ignition-transmitting tube.
