Abstract
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.
