Abstract

The invention relates to a ball cartridge (1) for a shotgun with an intermediate means (2) which can be built into a cartridge (20). The bullet (1) has a cylindrical free area (10) on the lower side thereof and the intermediate means (2) is embodied as a piston (21) on the end thereof facing the bullet (1) and the diameter thereof is adapted to the free area (10). In order to provide a solid link between the bullet (1) and the intermediate means (2), the bullet (1) is placed on the piston (21) or vice-versa and is pushed into the free area (10) and wedged during the piston (21) shot.

Claims

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.

7. The shotgun-barrel projectile according to claim 1, characterised in that a nose of the projectile merges via a bevel with an adjoining shoulder running parallel to the axis of symmetry, and the adjoining shoulder running parallel to the axis of symmetry merges with a plane face running perpendicular to the axis of symmetry and extending as far as the outer periphery of the projectile.

8. The shotgun-barrel projectile according to claim 1, characterised in that the intercalation consists of a plastic material and the projectile consists of a readily deformable material.

9. A shotgun-barrel projectile according to claim 8, characterized in that the projectile comprises lead.

10. A cartridge comprising a cartridge case, a propelling charge provided in the cartridge case, and a shotgun-barrel projectile with an intercalation according to claim 1 mounted on the propelling charge.

11. The cartridge according to claim 10, characterised in that a nose of the projectile merges, via a bevel with an adjoining shoulder running parallel to the axis of symmetry, and the adjoining shoulder running parallel to the axis of symmetry merges with a plane face running perpendicular to the axis of symmetry and extending as far as the outer periphery of the projectile, and the upper end of the cartridge case is retracted inwards by 180°

and rests on the plane face.

2. 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, and in that a ring is connected to the plunger on the outer periphery of the plunger via a predetermined breaking-point.

3. The shotgun-barrel projectile according to claim 2, characterised in that the ring is formed in one piece with the plunger.

4. The shotgun-barrel projectile according to claim 2, characterised in that ring constitutes a stop for the projectiles base.

5. The shotgun-barrel projectile according to claim 2, characterised in that the ring is L-shaped and with one shank encompasses the projectile almost as far as the nose of the projectile.

6. The shotgun-barrel projectile according to claim 5, characterised in that the one shank exhibits an inward-facing projection which engages a corresponding recess in the projectile.

12. The shotgun-barrel projectile according to claim 2, characterised in that a nose of the projectile merges via a bevel with an adjoining shoulder running parallel to the axis of symmetry, and the adjoining shoulder running parallel to the axis of symmetry merges with a plane face running perpendicular to the axis of symmetry and extending as far as the outer periphery of the projectile.

13. The shotgun-barrel projectile according to claim 2, characterised in that the intercalation consists of a plastic material and the projectile consists of a readily deformable material.

14. A shotgun-barrel projectile according to claim 13, characterized in that the projectile comprises lead.

15. A cartridge comprising a cartridge case, a propelling charge provided in the cartridge case, and a shotgun-barrel projectile with an intercalation according to claim 2 mounted on the propelling charge.

16. The cartridge according to claim 15, characterised in that a nose of the projectile merges, via a bevel with an adjoining shoulder running parallel to the axis of symmetry, and the adjoining shoulder running parallel to the axis of symmetry merges with a plane face running perpendicular to the axis of symmetry and extending as far as the outer periphery of the projectile, and the upper end of the cartridge case is retracted inwards by 180°

and rests on the plane face.
