As you know, smokeless powder contains its own oxidizer and will work on the moon if so called upon. I don't know if acid loses its magic in a vacuum. But on a custom made Douglas barrel I wouldn't want to risk it! Although if I could afford to take it to the moon...
Of course poorly washed nitrocellulose may have remnants of both nitric and sulfuric acid in the residue in any case. So a bit of Hoppes no.9 on a few patches is called for anyway.
