So I’m about to work on my brothers 223 and try and work what we suspect is a carbon ring out. Shows all the symptoms of one: high pressure at book minimum, black marks on bullet I give when removed from chamber, and it’s got about 750rds of varget reloads with not too much cleaning.

I’ve got the felt mandrels and special jag. I’ve never had to use these so are their any tips and tricks for their use?
Also, how long are you letting the CLR sit?
Is there Anywhere the CLR shouldn’t go?
Best method for removal of all the CLR?
Do you coat the bore after the whole process is done to prevent any remenant of CLR to etch?

I just found this in my old 22-250:

At the moment, I have an oversized q-tip soaked in BoreTech Eliminator sitting in there. I'll check it when I get home today. If that doesn't do it, I'll switch to CLR, which has worked great on carbon in the past. I think with most steels, there's no problem letting it sit in there for a few minutes. However, once I get the ring out, I'm going to do some passes with acetone, and then follow with some kind of gun oil.

Copper/bronze brush and battery drill.

You’ll probably need a copper remover after, as there will be pieces of the brush you’ll need to remove.

The drill makes quick work. Faster that running the brush 100x with your hand.
