The barrels include a cartridge chamber having an internal surface with a curvature. They also include a guide element located adjacent to and extending away from the cartridge chamber. The guide element is located at a point where a transverse movement of a cartridge being loaded ends during a loading process. The guide element has a surface having a circular shape whose curvature corresponds to the curvature of the internal surface of the cartridge chamber.
