PCT No. PCT/DE91/00796 Sec. 371 Date Aug. 7, 1992 Sec. 102(e) Date Aug. 7, 1992 PCT Filed Oct. 9, 1991 PCT Pub. No. WO92/07231 PCT Pub. Date Apr. 30, 1992.The invention relates to a subcalibre cartridge (1) for recoilless training weapons, whereby a counter-mass (10) is expelled with a cover or end cup (11) from a closed charge case (14) when the practice round is fired. To ensure certain tearing of the end cup, to even out the recoil at the same time and to reduce the safety area behind the training weapon, the bottom of the end cup (11) is provided with an opening which is covered with a foil (16, 17) that tears when the counter-mass is expelled. Self-adhesive aluminum foils are preferably used for this purpose.
