I used to just run patches through until things looked clean and call it done but there's a lot of information sitting in those patches if you bother to read them. The first one mostly tells you about carbon, the second tells you about copper and the third basically grades how well the first two did their job.
Context matters a lot here too. Seeing a copper heavy patch after thirty rounds on a brand new barrel is completely normal, that's just the barrel breaking in. Seeing that same copper heavy patch after thirty rounds on a barrel that's already broken in is a different story entirely and it usually means something is off with how the bullet is engaging the rifling. So really, the patches are talking the whole time, most people just aren't listening.
Do you actually read your patches or do you clean until it looks done and move on like I used to?
