Abstract
A method for uniformly sizing polymer-based cartridge necks in ammunition cartridges includes providing a neck sizer and aligning the polymer cartridge below the neck sizer. The cartridge is pressed into the neck sizer where the pressing step causes the cartridge neck to be compressed in the neck sizer so as to reduce the inner diameter of the cartridge neck to less than the maximum outer diameter of the bullet to be fired from the cartridge. The pressing step may also involve compressing excess polymer material from the cartridge neck through flutes in the collet die of the neck sizer to form external neck ribs about the outer surface of the neck. The neck ribs aid in concentrically aligning the polymer cartridge in the chamber of a firearm to improve accuracy of the bullet fired therefrom.
