Legal considerations In the United States, muzzleloading cannons made before 1899 (and replicas) that are unable to fire fixed ammunition are considered antiques. They are not subject to the Gun Control Act of 1968 or National Firearms Act of 1934. They may be subject to local rules in some jurisdictions, however.
