I disagree with your last statement. Friends who regularly and thoroughly clean their barrels using bronze brushes and up to date solvents have run into this problem. It seems to be strongly related to what powder is being used.
As an example, a friend, who shots a lot, has a bore scope, is a meticulous barrel cleaner and builds his own rifles, found that he got excellent accuracy and velocity in his .204 Ruger, shooting 32 grain bulletsin combination with VV 140, but he switched powders because it would carbon up so bad in the throat, in as little as 50 rounds.
Do you have a bore scope?
Also, there are reasons that I use cleaners like JB and IOSSO on an as needed basis rather than every time that I clean, and given the cartridges and powders that I use, that is infrequently. Having a bore scope has the advantage of being able to determine how often and to what extent things procedures and materials need to be used.
I agree that it is not a good thing to follow the if some is good more must be better approach. Often it is not. In many cases, less is better.
