Cleaning up my garage i found several old Remington percussion (Not Center Fire) cap tins. Inside one were extra nipples , another patches, and i couldn't get the lid off the third... so i doubt it had grease in it...
BTW, in Texas, the Penal Code 46.01 (3A, 3B) states a firearm doesn't include a weapon made or a replica of a weapon made before 1899, unless it uses rim fire or center fire ammunition.
Issuing a citation is NOT a statement of violating the law, (the back of most citations say so). It is used when Probable Cause is found that one MAY HAVE committed a violation. Only the judge,magistrate or jury can determine if you violated an ordinance, law or code.
I would've written the ticket and let the judge decide. That's their job, not mine.
