Desertcj, how do you use JB and Kroil?
This stuff is a LOT better penetrating oil than kroil

I tried all these, also

Recently, I bought a 308 barrel,31" heavy Palma. Guys said it had 400 rounds through it with 200g bergers. The groves were full of carbon from breach to muzzle! I tried all my favorite scrubbings and soakings. Then I plugged the muzzle with a cork, let the barrel sit in the Free All for two week intervals, scrubbed 10 strokes immediately with new bronze bristle brush, and after 6 weeks(3 soakings) there was still a little bit of carbon in the barrel. Next I scrubbed the barrel with Al Oxide mixed in honing oil. The barrel is now perfectly clean, ready to be Re chambered.
This is a barrel of a top manufacturer, cut rifle barrel. The grooves that were cut had uneven cut marks that looked like scratches or the cutter did not make uniform cuts. These are minor under 25x magnification of the Hawkeye, but this rough micro finish allows carbon to find a crevice to start filling up, then stacking up on.
As an F class shooter, the first owner of this barrel would shoot 60 shot strings getting the barrel very hot. His cleaning regiment was minimal at best. His gunsmith that sold this barrel to me was hesitant on selling it to me. I called him and told him how I got this barrel clean, we was amazed as we both had scrubbed the heck out of this barrel with good bronze bristle brushes and JB to no avail. 308's are generally easy on barrels, and I bet this barrel had more than 400 rounds on it, but the throat was in perfect shape...just unreal hard cooked on carbon deposits.
The barrel will serve well as a long range deer rifle where few shots are fired through a season.
