Try the Butch's bore paste or something similar then repeat with the 2000 Carbon remover and alternate them a few times.I received the slip 2000 carbon remover that someone recommended today. It's awesome stuff, cleaned my bolt up with hardly any effort. I was totally impressed by it and can highly recommend it.
It is water based, so follow their instructions. After applying, clean it out and then add a light coating of gun oil. I ran two dry patches through the barrel and then three passes with a bore snake. Then a patch soaked in Lucas gun oil followed by two more passes with a snake.
I scoped the barrel before and after. There really was no difference. Which leads me to believe that I'm probably seeing what Brett suggested, heat checking.
Someone recommended simichrone as well which just arrived. I'll try that too and report back.
The extra work may save you replacing a barrel.
