Abstract

The invention relates to a method for producing a core (1) for a projectile (2). So that the dividing behavior of the projectile can be set in a simple manner, wherein the core is lead-free, it is proposed that one or more wires or wire sections composed of a lead-free material are compressed to form a cavity-free core (1), wherein the wires or wire sections have one or more geometrical shapes (3) in the interior or on the outside diameter and/or predetermined braking points (4) obtained during the compression are provided in the core (1).

Claims

1. A method comprising the steps of:

compressing a wire or wire section wherein the wire or wire section comprises a lead-free material to form a core for a projectile, wherein prior to the compressing the wire or wire section has holes in an interior of the core of the wire or wire section, wherein said holes have the same diameter and,

wherein the core is cavity-free.

2. A method according to claim 1, wherein there are nine said holes, wherein one of said holes is a central hole and is surrounded by eight holes.

3. A method for producing a core for a projectile, comprising the steps of:

compressing a wire section wherein the wire section comprises a lead-free material to form a core, wherein prior to the compressing the wire section has holes in an interior of the core of the wire section, wherein said holes have the same diameter,

wherein after said compressing the holes no longer remain in the core and the core is cavity-free.
