Bullet and practice cartridge for use on a shooting range

Abstract

Disclosed is a bullet and practice cartridge for use on a shooting range having a cylindrical rear part and an ogive region at the nose end. The ogive region has a rear end and a bullet tip. In order that the bullet behaves like a conventional full metal jacket round nose bullet in a soft target, and moreover has a low energy output in the soft target, that the bullet does not deform or splinter in soft materials, and that the bullet does not puncture protective materials of bullet catchers, the bullet is constructed in one piece, the ogive region is closed all round a cavity and the wall thickness of the ogive region decreases constantly from the rear end to the tip.

Claims

1. A bullet for use on a shooting range comprising: a solid cylindrical rear part; an ogive region at a nose end, the ogive region integral with the cylindrical rear part, the ogive region comprising: a rear end; a bullet tip, comprising a wall of continuously decreasing thickness in the direction of the bullet tip; and a cavity within the ogive region closed on all sides by the wall of decreasing thickness; and lacking any predetermined breaking points, wherein the cylindrical rear part and the ogive region are formed from at least one starting material selected from the group consisting of a forgeable copper alloy, CuZn5-CuZn15, and CuZn30-CuZn45, and wherein the cylindrical rear part and the ogive region have a same ductility and hardness.

2. The bullet according to claim 1, wherein the starting material further comprises additions.

3. The bullet according to claim 1 further comprising a pyramid shaped hollow at a lower end of the rear part.

4. The bullet according to claim 1, having a caliber of 9 mm*19 mm.

5. A method for producing a bullet comprising: forming from a starting material a bullet blank having a cylindrical rear part and an open hollow cylinder at a nose end, the open hollow cylinder comprising a wall having a thickness decreasing from a rear end to a tip; and then shaping the hollow cylinder into an ogive region by means of an orbital forming process, wherein the bullet blank and the ogive region are not subjected to thermal post-processing, and wherein predetermined breaking points are not formed.

6. The method according to claim 5, wherein the bullet blank is produced by at least one of a chip-forming processes, a cold-forming processes, or hot-forming processes.

7. The method according to claim 5, wherein the hollow cylinder of the bullet blanket is formed to have a conical shape.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

(1) FIG. 1 shows a bullet blank after the turning process and before the treatment by means of an orbital forming process.

(2) FIG. 2 shows the finished bullet, which has been formed by means of an orbital forming process after the turning as a chip-forming process.

(3) FIG. 3 shows a bullet according to the invention captured in a bulletproof vest after being shot.

DETAILED DESCRIPTION

(4) FIG. 1 shows a bullet blank 5 after the turning process and before the treatment by means of an orbital forming process, said bullet blank having a cylindrical rear part 1 and a hollow cylinder 6 at the nose end. The hollow cylinder 6 has been hollowed out by turning and is open at the tip 7. The wall thickness 9 of the hollow cylinder 6 continuously decreases from the rear end 8 to the bullet tip 7. The outside diameter D 1 of the hollow cylinder 6 at the bullet tip 7 is less than the diameter D2 of the rear end 8 of the hollow cylinder 6. These two measures make the later orbital forming process easier. A pyramid-shaped hollow 4 has been made at the lower end of the rear part 1.

(5) FIG. 2 shows the finished bullet 10, which has been formed by means of an orbital forming process after the turning as a chip-forming process. In the orbital forming process, the ogive region 2 is formed and a cavity 3 is enclosed.

(6) FIG. 3 shows a bullet 10 according to the invention captured in a bulletproof vest after being shot. Said bullet is substantially dimensionally stable and not splintered, and the cavity is compressed. A bullet according to the invention does not deform or split when said bullet hits a soft target (gelatin) and therefore is identical to the bullet according to FIG. 2.
