发明名称 Compressible shot shell
摘要 A shot shell such as would be utilized in a shotgun or the like, wherein the cartridge forming the shell has a collapsible extension removably or permanently engaging the shot end of the cartridge, with the cartridge configured to provide a un-compressed length of, for example, 2.50 inches (the minimum length of shell for conventional automatic or semi-automatic, magazine fed shotguns. The collapsible extension is configured to be compressed when placed in a spring-fed magazine, so as to provide increased magazine capacity when compared to standard length shells, while expanding when removed by from the magazine during a loading cycle, so as to facilitate reliable placement of the shell into the breach from the magazine. The collapsible extension in the loaded cartridge of the present invention is configured to be ejected from the barrel upon firing of the cartridge. The present system thereby provides a means to increase the capacity of conventional automatic or semi-automatic (i.e., pump actuated) shotguns, while reducing the likelihood of jamming or malfunction due to utilizing shells which are shorter than the firearm was designed to process.
