I do agree with what other's have said if this is a gun you want to keep if it is a practise gun then go for it. but with that being said I will try to answer your question because I am sure you will be trying it on you own.What type of file would you to remove pits from a round barrel? Wouldn't filing a with a flat file create flats on the barrel?
Respectfully:You shouldn't be working on a gun!
I spent a year, and a half, working with two very skilled gun smiths, as an apprentice. Maybe you could find a smith in your area that would teach you. There are also gunsmithing courses that you can take from your home. But they can not teach you how to draw file. That takes time, and experience, to learn. Best of luck with learning gun smithing! It is a rewarding hobby/job.Respectfully:
I'm not working in any gun my good sir. I'm just curious, so instead of screaming, "don't work on gun!" just explain what you have to do, as others have already done. I'm interested in gun refinishing, but I don't know much, if anything at all, about the trade and what's involved; hence why I'm asking.
I saw a video of a smith draw file on an octagonal barrel, but I wondered if this work on a round barrel; I had the line of thought it would leave filing flats.
I would to think that I'm smart enough not take on such an endeavor without thoroughly studying what is involved and practicing on something that is not worth a quarter of a grand.
I have to correct what I said I do draw file when needed but was apprehensive to say this with out having to go into how to do it. This is to be done slow and you must have experience in doing it if not you can end up worse off then just having to deal with the pitting.You can take off allot of steel real quick with the wrong file and no experience.There have been times were I used a file to remove pits on a barrel by it how sprint described. Its called draw filing and it take tons of practice. Many times I'll use it in conjunction with my lathe to turn the barrel while I do it. You need a good smooth cutting file, a file brush and a smooth even pressured stroke. Ill even use chalk to keep the cut pattern light. And yes you can go way to far. Waves in the barrel can easily be cut and you can go to thin, If the pits are that deep, they should be tig welded or just left alone. There is no fast alternative to bluing prep.
I wish, really wish, there was someone like that here . The smith in my local area is crook in my opinion.I spent a year, and a half, working with two very skilled gun smiths, as an apprentice.

Some of the best gunsmiths, and gun manufactures started as machinists.Another good place to learn to draw file is in a tool, and die, shop. That is usually where they start you out, learning to draw file.
Type "learn gunsmithing at home" into your search engine, google, bing, or what ever you use. You will get a list of schools that will teach you how to smith, with out leaving your house. I don't know enough about the schools out there to make a recomendation, but there are some here, on the forum, that will know.I wish, really wish, there was someone like that here .

I had badly pitted Marlin 336, this before I caught on to gunsmithing, and took it to him to clean up and refinish; it also had a problem of rounds hanging up in the magazine.
He told me he could only duracoat, I should've of walked away right there; but I didn't know any better at the time.
Charged me 200 dollars. Now I waited a month for the finish to cure before firing, or any rough handling.
When I took it to the range it still had a hanging issue; when I brought it home to put up on the rack brushed the barrel on side of the wall on accident. The wall was fine, but the barrel flaked slightly, and it only got worse as time wore on.

There's saying I've read "A good gunsmith is good machinist, but a good machinist is not always a good gunsmith."
There's a college that's a ways from me ,but still in state, that offers machine tooling courses, and I've been giving a heavy amount of thought of moving down there and taking the course as my first step towards gunsmithing, and having a trade skill.
