Abstract

A gun barrel cleaning shell uses a pressurized cartridge alone or within a shell casing to propel cleaning material through the bore of the firearm. Inside the cartridge is a strike pin that when the firing pin of the firearm is actuated will cause the strike pin to puncture a rupturable end of the cartridge to release the compressed fluids therein to force the cleaning material toward and through the barrel of the firearm.
