Just before I start the powder I take a dry mop sprayed with Dry silicone lube and mop my cylinders. 1 ROA, 2 7.5" 58 NMA's, 2 5.5" NMA's, 3 spare cylinders. So by the time I get back to the ROA it's cooled off still out comes the mop. I have no proof but I think that fouling doesn't stick because of this, I haven't been shooting much lately; just closed on an old house [plumbing, wireing, new doors/windows, etc.] but could these embers be the new fangled powders, and a shortage of 'Holy Black'??
