    Abstract: An insert for a high strength polymer-based cartridge casing (400) can include an outside, an inside formed within the insert, and a back end (402) disposed at a rear of the cartridge casing. The back end includes a rim (406) and groove (404) 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 (408) 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 (418) can be included inside the insert and communicating between the primer pocket (416) 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.
