1. A shotgun-barrel projectile with an intercalation for fitting into a cartridge, the projectile exhibiting a cylindrical free space on its underside, and the intercalation taking the form of a plunger at its end facing towards the projectile, this plunger having a diameter adapted to the free space, characterised in that the projectile is mounted onto the plunger, or conversely, so that before firing the plunger is not wedged in the free space and the plunger is pushed into the free space and wedged in the free space in the course of firing, the free space exhibits a projectile spigot arranged on the axis of symmetry, the plunger exhibits a bore arranged on the axis of symmetry, the projectile spigot and the bore are substantially adapted to one another in diameter, the projectile spigot and the bore are endowed with wedging elements which in the course of firing and insertion of the plunger into the free space bring about a wedging of the plunger and therefore of the intercalation with the projectile, and the wedging elements include a hollow cylindrical design of the end of the projectile spigot facing towards the intercalation, the underside of the projectile spigot exhibiting an inwardly inclined bevel, the bore in the plunger exhibiting a hemisphere arranged at the bottom, and, in addition, a diameter reduction being arranged on the wall of the bore above the hemisphere.
