Improved geometry for polymer ammunition cartridges

An improved polymer-based cartridge includes a primer insert defining a base end and connected to a cartridge body that extends forward to a shoulder region and has a length defined by industry standards for that caliber. A cartridge nose extends forward from the cartridge body and has an industry standard outer angle. An interference region, noncompliant with the industry standards, connects the industry standard angle to the neck. The interference region causes interference between the cartridge nose and a shoulder support surface defined by an industry compliant firearm chamber of the same caliber. The improved polymer cartridge thus exceeds maximum dimensions set by industry standards. A second interference region can be defined at the distal end of neck and is a result of an increase to the overall axial length of the cartridge in comparison to the corresponding length in an industry standard cartridge.
