N/A How much to clean barrel?

So this is 4 patches and 10 passes. Accuracy was fine but it’s so dirty. Do I go until completely clean?

Yeah, just keep going until the patches come out...clean ! Then...run another patch... one more time.

Reminds me of a Smith and Wesson Mod 59 (9mm), that I bought, MANY years ago. I bought it from a city cop.
I took it apart to give it a good cleaning. The barrel was SO...full of lead, that you could NOT see see the rifling in the barrel. None of it. It took a LOT of scrubbing to get that thing clean, and I never was SURE...that I got ALL of the lead out of there.
