Copper Fouling - Fact or Fiction?

[Mags]

Perhaps a nylon or bronze brush?
...

A few Youtube videos later, seems my 30-30 has a bad case of baked in carbon fouling behind the muzzle. Did the bronze and nylon brushes with every bore cleaning solvent I have. Got some carbon out, but hardly touched it. Several Youtube videos imply that one the carbon fouling becomes hard baked even carbon fouling cleaners will hardly touch it.

Hmm..that's a head scratcher. I wonder what else might work to get in those lands without getting too aggressive.

I have had good experiences with Tetra Gun Copper Solvent with a tonada brush. The instructions state to let the solvet set for 15-30 minutes at a time. I found that letting it set closer to 45-60 minutes at a time yeilds better results.

I have used a Tornado brush before, but I don't see it getting down into the lands. The Tetra solvent is good.

Thanks. That's exactly what I did and used. Works great for copper and mild carbon stains, but has no effect on globs of hard baked in carbon.

Great. Should had read closer. Thought you were dealing copper. For carbon, I have used Flitz on external parts. Have not had to deal with a barrel. But, I would probably try Lead Away or Flitz for a revolver barrel. A patch of Lead Away may work in a longer barrel also?

I spent a good part of today working on the carbon behind the muzzle with whatever household solvents we have that I thought safe for gun metal steel and barrel bluing. I got nowhere with the household stuff. I finally resorted to using Wheeler 220 Grit Bore Lapping Compound. Applied the compound to a patch wrapped around a bronze bore brush. A gazillion in and out stokes later, in and out so as not to cross stroke the rifling, I do believe I got the carbon out. But in so doing revealed bad bore cutting chatter underneath. The chatter probably why the carbon built up in it. Before and after pictures.

Unfortunately, looks like that bore is now poised to catch more...no?
Good job getting it clean though.

Yup and thanks.

Looks clean! Maybe, that will have to be part of your normal routine, for awhile? From what I have read, lapping a barrel can smooth it out some. I have not tried it. I just been shooting and cleaning, hoping that things will smooth out, someday.
