I'm sure the answer is in here somewhere, but the search engine came up short. So. What's best for getting rid of copper build-up deep in the lands of an old barrel?
Thanks in advance for a recommendation.

I just started using the Boretech line, outstanding and doesn't smell.
Been using a Hawkeye borescope for the past 8-9yrs; in every single one of my custom bbl with a lapped bore, I see pretty much the same thing - some copper fouling out at the muzzle, sometimes extending back as far as 2"-3". Krieger's explanation is that a minute amount of copper is vaporized off the base of each bullet when it's fired, and when the bullet exits the muzzle, temp & pressure inside the bore drops off instantly, which causes the copper to come out of the vaporized state and be deposited in the bore at that point.
