When shooting precision begins to deteriorate in the past, I've "completely" removed the copper fouling and started the break in process as if the barrel were new. Depending on who you ask, the break-in process is something like: shoot 1 then clean, shoot 2 then clean, etc. until very little copper comes off on the patches. Then it's considered broken in. My question is, how does the cleaning procedure for "complete" removal differ from break-in removal? It seems to me that if you used the "complete removal" procedure during each step of the break-in, you would remove all of the copper at each cleaning and essentially end up with a barrel that wasn't broken in.
