The real danger of lead and plastic fouling, in barrels that are not chrome lined, is that moisture eventually gets underneath the fouling and corrodes until it is either cleaned out or pits form. IMO, most pits we find in older barrels are from moisture underneath lead fouling. Of course, the corrosive primers back then only hastened this. Fouling is EVIL, and I strongly disagree with the skeet lady champion that each shot cleans the residue from the last. It does NOT!!
