WOW.. I never realized that the crud ring from Triple Se7en could be that bad. You would never think that climate would make that kind of difference. Here in Wisconsin I shoot the Triple Se7en in my rifles and granted there is a fowling, but nothing that a simple wet patch will not remove. I never realized that it could be that bad... No wonder some of the people on these boards are so concerned about finding a powder that will not fowl. I think Pinnacle might be a real solution for you and others like you.
