Abstract

A projectile (1) for a cartridge for hand-held firearms comprises a core (2) and a core jacket (3). The core (2) is made of a material which has a higher specific gravity than the material of the jacket (3). The core (2) and the jacket (3) are positively interconnected.

In order to achieve a high penetrating power and a man-stopping effect and to ensure that the trajectory will be relatively short in case of a miss, the core (2) of the projectile is integrally formed on its periphery with deformed portions (6), which extend radially outwardly within a diameter range which is determined by the maximum core diameter and serve to establish a positive joint with the core jacket (3), and in a manner known per se the core jacket (3) is open toward the tip of the projectile.

Claims

1. A projectile for a cartridge for a hand-held firearm having a barrel of a predetermined caliber, the projectile comprising a core having a maximum diameter, and a jacket surrounding the core and having an outer surface of a diameter corresponding to the caliber, an inner surface of a diameter corresponding to the maximum core diameter and an open forward outer end opposite the cartridge, the core having a tip extending freely through the open jacket end, the core consisting of a hard material and the jacket consisting of a material softer than the core material, the core material having a higher specific gravity than the jacket material, and the core having deformed peripheral portions extending radially outwardly to an extent substantially equal to the maximum core diameter and into the inner jacket surface to establish a positive joint means between the core and the jacket, the positive joint means being firm enough to hold the core and jacket together upon impact on a softer target but not strong enough to resist an impact on a hard target.

2. The projectile of claim 1, wherein the positive joint means extends over a minor axial portion of the core.

3. The projectile of claim 2, wherein the deformed peripheral core portions define at least three peripheral grooves at a bottom end portion of the core opposite the tip.

4. The projectile of claim 3, wherein the deformed peripheral core portions are screw threads.

5. The projectile of claim 1, wherein the tip of the core protrudes from the center of the open-ended jacket.

6. The projectile of claim 5, wherein the core has a cylindrical portion axially adjoining the deformed core portions, and the tip is a conical portion axially adjoining the cylindrical core portion..

7. The projectile of claim 5, wherein the core has a cylindrical portion axially adjoining the deformed core portions, the cylindrical core portion having an outer end flush with the open end of the jacket, and the tip is a conical portion axially adjoining the cylindrical core portion.

8. The projectile of claim 2, wherein the inner jacket surface defines three axially extending grooves extending from the positive joint means to the open end.
