INTERNAL barrel rust? can you remove it all?

is it possible to remove all barrel rust or is that determined on how pitted a barrel has become? ie..i assume most rust starts in the rifling....do you just keep cleaning and patching and swabbing until you get it clean or as clean as your satisfied?...i assume wants its there its there and you can only control it as much as you can.

A properly sized bronze bore brush will get most of it quick with any kind of lube or cleaner to flush the barrel and brush out as you go. Then patch clean with cleaners. Then shoot. I have an old Mod 70 that is pitted up, but shoots great groups in spite of it. Coppers up like a bugger tho!

You certainly can remove it all but just understand that the rust is the barrel. It's not extra iron that got in there somehow. However small or large it may be when you remove the rust you are leaving behind some size of indentation in the barrel. The pitting occurs due to rust removal.

This is a 60 year old chromoly barrel that has no rust but you can see a fair amount of pitting from previous rusting and a lot of embedded copper. This gun is just a bear to keep free of copper. Click on pic.

Lead and copper fouling can be brushed out with a "dry" copper brush. I would imagine oxidization could be too. Dry is the key. Wet brushing tends to glide over. Only takes a couple passes. You'll see the dust fly. If you can see pits at the end of the barrel on the lands after brushing, time for another gun or new barrel. Minor pits can be filled by shooting a few rounds followed by a wet patch with lube.

How can you remove copper with a dry brush? I shoot and clean way more than the average person and have never seen or heard of anyone cleaning copper with a dry brush, same can be said for carbon fouling.

Re: INTERNAL barrel rust? can you remove it all?

Sorry I didn't specify. Rust (the subject of the OP) and ''light copper and carbon'' comes right out with a dry brush. Really heavy copper fouling in barrels that have 300-400 hundred rounds through them before cleaning, takes a strong solvent. I like M-Pro 7 products. Just don't let their copper solvent sit on blued surfaces. Their copper solvent only took 2 apps to remove heavy copper deposits from a grossly neglected barrel. After I dry-brushed it a few times, I just mopped it in, let it soak 10 minutes, brushed it 5 passes in each direction and swabbed it out. Good stuff. Better than all the rest I've tried. Rust alone is easy to remove if it is dry. Give dry brushing a try. It really gets out a lot of dust. Again, anything wet also acts as a lubricant. Those spiral loop brushes clean the lands well too. They don't get a thing out of the grooves though.
