I put 25 rounds of Brenneke slugs through my Benelli M1 at the range today, and found that I had some unusual fouling in the barrel. It was the first 6-8 inches forward of the chamber. There was some leading which cleaned up easily, but the remaining stuff (plastic?) proved very difficult to remove. Solvent seemed to have little effect, and scrubbing with a brass brush didn't faze it. I finally got most--but not all--of it out by pulling a Boresnake through about 20 times.
Does anyone know what this stuff is and how to get rid of it? Appreciate any suggestions.
