A non-toxic highly frangible training round bullet, and a method of making same, in which a plurality of segments of non-toxic metal selected from a group including zinc, iron, steel and copper are grouped or arranged within pressure-molding equipment and sufficient pressure is applied thereto to cause such segments to inter-engage and cohere, one to another, while being formed into a desired shape of bullet and retaining their individuality at least to a limited extent. Upon impact with a target, such a bullet fragments to a large extent along at least some of the original physical boundary lines of the original segments into new segments which are relatively small as compared to the size of the original segments. There is no substantial ricocheting or "bounce-back" activity associated with such fragmentation and, of course, there are no toxic effects.

[ We claim:] [1.] In a method of manufacturing a non-toxic highly frangible training round bullet core which is relatively safe with respect to ricochets and bounce-back actions, and therefore being of use in training exercises for law-enforcement personnel as a relatively safe training round, comprising:(a) selecting a plurality of segments of a non-toxic metal selected from a group of non-toxic metals consisting of zinc, iron, steel and copper, said segments having original physical boundaries,(b) twisting at least some of said segments about other of said segments into inter-engaging relation, and(c) swaging said twisted segments of non-toxic metal into a twisted mass having the shape of a bullet having a generally cylindrical rear portion and a generally truncated nose portion, with sufficient pressure to cause said segments to distort, inter-engage and cohere one to another while retaining their individuality at least to a limited extent, and to thereby cause said individual segments, upon said bullet core striking a target, to fragment along at least some of the original physical boundaries of said segments into separate, discrete and relatively small fragments which are smaller than the original size of said segments.
