ABSTRACT:
A cartridge in a weapon capable of firing several different calibers is provided. The cartridge bore is adapted for use in weapons having extractor and positioner mechanisms which permit use of different caliber casings in the same weapon. With the cartridge bore according to the present invention, casings are more easily removed after firing and are less likely to stick.
