Zusammenfassung:ONE-PIECE SHOTSHELL CASING A single-piece plastic shotshell casing and method of making same comprising a tube of high density polyethylene which is uniformly biaxially oriented to a substantial degree throughout its length and has sidewalls of constant internal diameter, thickness, molecular orientation and physical strength, one end portion of the tube being softened with heat and formed into a substantially thickened integral transverse base section with a longitudinally extending primer opening therein, the base section being substantially biaxially oriented. Also, a shot cup of the same construction as the casing, except that its transverse base section is imperforate, is disclosed.
