Abstract

The invention relates to ammunition that is used for target practice and/or sport shooting with an individual live-fire weapon. The inventive ammunition comprises a cartridge case (1) that defines a receiving chamber for an explosive (5), the transverse dimension (D1) of said chamber being at most of the order of that (D2) of the rear face of the missile (2). Said case (1) is formed from a hollow resin mass. The longitudinal dimension of the chamber (4) is also reduced with positive connection means being inserted between at least any two of the elements (6, 5, 2) which make up the series of elements involved in the chain operation of the ammunition and which are disposed at a distance from one another.

Claims

1. Ammunition for effecting target practice and/or sport shooting with an individual live-fire weapon, this ammunition principally comprising a cartridge case (1) defining an inner volume forming a chamber (4) for receiving a reserve of explosive (5), this case (1) successively receiving a series of elements for the chain operation of the ammunition, from its rear end (7) towards its front end (3), comprising a primer (6), the reserve of explosive (5) and a projectile (2), the volume of the inner chamber (4) of the case (1) being diametrally reduced so as to give the chamber (4) a transverse dimension (D1) at the most of the order of that (D2) of the rear face of the projectile (2), characterized in that the reduction of the volume of the inner chamber (4) of the case (1) is also a reduction in longitudinal dimension.

2. Ammunition according to claim 1, characterized:

in that the diametral reduction of the inner chamber (4) of the case (1) results from an increase in the thickness (e) of the latter (1), which is formed by a hollow resin mass, this hollow forming the chamber (4) for receiving the explosive (5).

3. Ammunition according to claim 1, characterized:

in that positive connection means (4,8,10) are interposed between at least any two elements (6,5,2) making up the succession of elements for the chain operation of the ammunition, rendered distant.

4. Ammunition according to claim 3, characterized:

in that the connection means are constituted by an added striking pin (8) interposed between the primer (6) and the rear end face (9) of the ammunition, against which the shock of the striking pin of the weapon is provided to be applied.

5. Ammunition according to claim 3, characterized:

in that the connection means are constituted by the inner chamber (4) of the case (1), the latter constituting not only a chamber for receiving the explosive (5), but also a chamber for receiving the projectile (2) inside the case (1).

6. Ammunition according to claim 3, characterized:

in that the connection means are constituted by an axially extending member (10) extending the rear face of the projectile (2) towards the reserve of explosive (5).

7. Ammunition according to claim 1, characterized:

in that said case (1) and said projectile (2) are provided with elements in relief (22,32) for temporarily blocking said projectile with respect to said case.

8. Ammunition according to claim 5, characterized:

in that said element in relief (22,32) are adapted to be temporarily locked, by wedge effect, during closure of the weapon, before firing.

9. Ammunition according to claim 1, characterized:

in that said case (1) comprises a part (14) of substantially cylindrical outer form of circular section.

10. Ammunition according to, claim 1 characterized:

in that said case (1) comprises at least one part (12,13) of substantially truncated outer shape.

11. Ammunition according to claim 1, characterized:

in that said case (1) is provided with a shoulder (15) which facilitates engagement of the ammunition with the extractor of the weapon.
