Abstract:
1. A method for fabricating jacketless cored bullets, including both a partly fragmenting bullet and a deformable bullet, comprising: fabricating a deformable bullet having a bullet tip and a bullet tail, and having an enclosed cavity within the bullet tip, the enclosed cavity being closed by a cap, the deformable bullet comprising a base alloy of copper and zinc; and fabricating a partly fragmenting bullet having a bullet tip and a bullet tail, and having an enclosed cavity within the bullet tip, the enclosed cavity being closed by a cap, the partly fragmenting bullet comprising a base alloy of copper and zinc; wherein the partly fragmenting bullet is fabricated with an impact point position, a caliber, an external volume, a mass, and a center of gravity substantially identical to that with which the defomiable bullet is fabricated, but wherein the enclosed cavity of the partly fragmenting bullet is enlarged relative to the deformable bullet by an additional portion and wherein a mass loss caused by enlargement of the enclosed cavity of the partly fragmenting bullet is compensated by changing relative proportions of copper and zinc in the base alloy and/or by adding at least one element positively influencing fragmentation at the cost of the copper and zinc of the base alloy.
