An insert for a high strength polymer-based cartridge casing can include an outside, an inside formed within the insert, and a back end disposed at a rear of the cartridge casing. The back end includes a rim and groove disposed around the outside of the insert and a primer pocket disposed inside the back end. Also included is a front end, opposite the back end, having an overmolded area disposed around the outside of the insert above the primer pocket and a basin, having a depth, formed inside the overmolded area. A flash hole can be included inside the insert and communicating between the primer pocket and the basin. The flash hole has a perimeter and a ring disposed around the perimeter of the flash hole, including a height starting at a bottom of the basin, disposed toward the front end, and less than the depth of the basin.

Base insert for polymer ammunition cartridges

A cartridge for ammunition has a base with an axial end section. An annular wall extends from the enlarged outer peripheral lip section to an opposite end. The axial end section has a primer cavity therein and a radially outwardly extending peripheral extraction lip. An annular ledge is axially positioned at an inner end of said primer cavity and radially extends inwardly from said annular wall. A passage has a reduced diameter compared to the primer cavity and extends through the annular ledge. A main charge cavity is at an opposite side of the ledge from the primer cavity. A knurl section is on an outer surface of said cylindrical wall. A cartridge case is attached to the base about said knurl section.
