(b) Barrel. After firing a proof cartridge, on visual examination, the barrel shall be free of cracks, bulges or splits.
(c) Cylinder (revolver). After firing a proof cartridge, on visual examination each chamber shall be free of cracks, bulges or splits. Cylinder stop notches (bolt notches) shall be formed to ensure positive engagement of the cylinder stop at each position aligned with the bore.
