IMO people often overlook carbon fouling. I think in some rifles its worse than Cu. If all the carbon is not gone you may not be able to attack the Cu. Or, you may just have a great barrel for not fouling.

Current wisdom seems to be that carbon is your enemy as opposed to copper. As in get the carbon out and leave the copper till it starts to degrade accuracy, being that it fills in any voids in the bore. Makes sense to me. But I remember when copper was the devil, or maybe the bore solvent companies just perpetuated that??
