A single-piece plastic shotshell casing and method of making same comprising softening one end portion only of a tube of uniformly biaxially oriented high density polyethylene sufficiently for forming and until a dollup is formed, then telescoping only a portion of the dollup into the rigid sidewalls of the tube, and then forming the dollup into a substantially thickened integral transverse base section constituting a head with a longitudinally extending primer opening therein, the base section being substantially biaxially oriented and the rigid sidewalls terminating a substantial distance inwardly from the outer end of the base section.

Shotshell casing with partially telescoped basewad

A single piece plastic shotshell comprising a tube of high density polyethylene which is uniformly biaxially oriented to a substantial degree throughout its length and has side walls of constant internal diameter, thickness, molecular orientation and physical strength, the tube having a substantially thickened integral transverse base section formed of a compressed length of the tube at one of its end portions with a longitudinally extending primer opening therein, the base section being substantially biaxially oriented and telescoped within said end portion of the tube. Apparatus and methods for making the shotshell are also disclosed.
