Default Can a Tumbler be Used to Polish a Barrel?

Just curious. I have heard tumbling doesn't affect the casing, just removes the dirt and residue. If this is true can a tumbler clean and polish a barrel?

Why not? You can throw anything you want in there as long it is not hazardous to you or your health

Tumbling media, all of it, is somewhat abrasive.

I would be concerned with the possible damage to the
crown and chamber areas.

Other than that......

Rubber or cork plugs? Can you elaborate? I am not familiar with these.

What do they do in the polishing process? What is their role mixed with the walnut/corn and such?

He means plugging the barrel with them.

Most tumbling media in itself shouldn't be abrasive on a steel barrel. There's no way walnut or whatever will be harder than barrel steel. If you tumbled in steel shot, yeah, that might be an issue.

Polishing compound may be a different matter, depending on what it is.

I can't honestly see tumbling causing any damage to a barrel if the crown is protected (detectable damage to the chamber seems very unlikely), but I also can't see it doing that much good either.

Many tumblers have a bolt that runs right inside of the tumbler and is attached with a lock washer for the tumbler cap cover. Depending on what Tumbler maker you have, most tumblers not only vibrate but moves the media and shells side to side. That will cause the barrel to hit the metal bolt and gouge your barrel.
Second, if your barrel ramp is polished and throated it is not advisable to do such a thing. If you want to polish your barrel my suggestion is to invest on a Dremel Tool and a polishing compound. This is the best way for polishing.

No. You cannot use a tumbler to polish a barrel...not even if you have a really BIG tumbler... barrels do not like to be tumbled... I know I asked one, and it told me so. Seriously though, you can bead blast, parkerize, blue, many, many things, up to and including using very fine emery and even a polishing wheel
to bring out a nice lustrous finish if that is what you are after. If you did tumble a small barrel, it would remove the tarnish but not scratches... where the more traditional polish methods do refine out the fine scratches.

Normally a barrel would be polished using cloth wheels and various grades of polishing compound -- A pistol barrel may fit the average tumbler, but it would require a pretty sizable unit for a rifle barrel -- Point taken about a tumbler with an axel, but I can't imagine walnut or corn doing any damage to a barrel or removing much rust or whatever --
