<p>A non-toxic bullet (25) comprised primarily of zinc, and having smooth circumferential surfaces throughout, with its rear portion (26) being cylindrical and its forward portion (27) tapering inwardly and forwardly. When used in the simple non-encased form, or completely encased in a nylon or electroplated copper casing, it functions well as an inexpensive, non-toxic training round. When used as core in combination with a copper casing (59) enclosing the nose (58) and all but the rear end surface, my non-toxic bullet meets the requirements of a non-toxic non-frangible bullet. When my bullet is used as a core, with its rear end secured within the open end of a cup-shaped copper casing, it functions well as a non-toxic non-frangible bullet. If the core is constructed with weakened areas at the rear, and is mounted in the sanme type of cup-shaped copper casing, it performs in an improved manner as a frangible bullet.</p> |
