Abstract

A non-toxic, highly frangible elongated soft-point training round bullet core which will disintegrate upon striking its target, for use in a training round in training exercises for law enforcement personnel and having a central heart of non-toxic metal selected from a group consisting of zinc, iron, steel, and copper with a plurality of wires of non-toxic metal selected from that group twisted around said heart throughout its length prior to being swaged into deforming and inter-engaging relation with the heart, and the core having been subsequently swaged into the shape of a soft-point nose of a bullet, with pressures sufficient to cause the strands of wire and the heart to inter-engage and deform while retaining their individuality at least to a limited extent, whereupon substantially all of the strands of the core, upon the core being fired and striking a target, will fragment along at least some of their original physical boundaries into discrete fragments smaller than the original size of the bullet.
