How much time do you guys spend on metal fouling. In your average cleaning session, do you guys consider metal fouling to be important or not. Recently I did some reading about copper and lead fouling and I started inspecting my barrel more carefully, and have found a good bit of discoloration, as in copper/lead. I have always thought I did a very good job of cleaning on all my guns, and took pride in my work, but I think I have been overlooking metal fouling. I was more concerned about powder residue,and lubrication/protection in the past, and just curious, as to what you guys do. I purchased some copper remover, and it is improving the situation but was not sure if I should add this chemical to my normal cleaning job, or just clean for metal less often. Thanks
