If you intend to use a file on barrels it is a must that you chalk it well first otherwise it will pick up filings that clog the file and leave score lines in the metal, and the softer the metal the deeper the scoring will be. Better still fix with adhesive wet and dry paper of various grades to lengths of hard wood this not prone to clogging and leaves a far better finish.
