The invention pertains to a method for producing a barrel marking on the inner side (4) of the barrel (2) of a firearm. Barrel markings on firearms are used for marking projectiles fired from the respective firearm and to thusly allow a largely definitive allocation of a projectile to the weapon from which it was fired. The invention is characterized by the fact that at least one groove which follows the rifling (5) of the barrel is mechanically produced in the barrel wall by means of a finger-like tool (1) that can be displaced relative to the longitudinal axis (6) of the barrel and turned about the longitudinal axis of the barrel, namely after the inner side of the barrel (2) is finished, preferably during the manufacture of the barrel. The invention also pertains to thusly manufactured barrels and to a device for carrying out said method.
