The invention relates to a training flight begins. This ensures that the counter cartridge with a decaying projectile that emerges from one above the corresponding sharp projectile very Plastic casing and, if necessary, a lightweight sub-caliber projectile up to about the tube body formed filling made of metal powder, mouth is safely guided in the tube. Denial chips or the like. Accordingly, it cannot happen that the sub-caliber projectile for peaceful shooting training is caused by passing gases It is desirable for troops to have ammunition still in the barrel from its intended trajectory, which a target shooting within a counter-steered, which could have the consequence that it significantly reduced amount is thrown against the inside wall of the pipe over the sharp shot and is thrown into the area made possible, with which, however, at the same time it may shatter.

One by the size and Shape of the opening 8 certain propellant gas amount enters the firing channel and moves in it This is followed by the projectile 5 with more or less great speed relative to the decay projectile front. In the meantime, the delay set ignited by the hot propellant gases has also burned down and accordingly, the branch bore 9 is free, so that further propellant gases penetrate through this into the firing channel and give the projectile 5 the additional impulse required or desired for its flight.

To ensure that the projectile 5 is on the one hand guided along the entire length of the barrel of the weapon is, on the other hand, by the subsequent dismantling of the decay bullet, it is not over its intended trajectory is deflected, care must be taken that the conditions so are chosen that the projectile 5 emerges from the firing channel just before the decay projectile the Tube leaves and, through the exit of the decay projectile from the barrel muzzle still in the Firing channel existing or still favored by propellant gases passing through it, disassembled.

Independent of this, by choosing the Relationships, for example by appropriate coordination of the cross-sectional dimensions of normal caliber Decay projectile to sub-caliber full projectile 5, by dimensioning the opening 8, through Number and dimensions of the holes 9 or choice of more or less heavy material for the full floor 5 the flight range of the latter can be largely influenced in the desired manner.
