Abstract
A barrel has a barrel body that extends a barrel length and a bore extending through the barrel body. The bore has a cartridge chamber section and a rifled section with a bore diameter. A cartridge shell fits within the cartridge chamber section and the projectile extends from the cartridge chamber section into the rifled section. The cartridge shell with the projectile has a shell length within the bore, the barrel length is less than twice the shell length. The rifled section has rifling grooves between rifling lands, and each of the rifling lands has a land width. The groove diameter is greater than the land diameter by an amount that is more than one half of the land width. The barrel body has an extractor assembly with an arm retractably extending from a cavity. The arm can rotate in the cavity when extended and does not rotate when retracted.
