Abstract: A cartridge has a polymer case with a mouth, a neck having a neck thickness (Tn), a shoulder, and a body having a case thickness (Tc). The body has a flat portion comprising a minimum thickness, a pull thickness (Tp), and a dip comprising a dip thickness (Tb). The cartridge also includes an insert attached to the polymer case opposite the shoulder. The insert can a bulge engaging the dip to maintain the insert on the polymer case. Tb and Tn are related by 1.0≤Tb/Tn≤1.5 or just

Abstract: A high strength polymer-based cartridge having a polymer case with a first end having a mouth. A body can be formed below the mouth and having a propellant chamber and a longitudinal axis. A back end can be formed opposite the first end and formed below the body, with a first snap ridge comprising a first ridge angle at approximately at 90° to the longitudinal axis; and a second snap ridge, positioned closer to the first end than the first snap ridge, comprising a second ridge angle at approximately at 90° to the longitudinal axis. Further, an insert is configured to engage the back end.
