About the 777 "crud ring" another thing I am starting to notice is the guys that seem to not have as much problem with the crud ring or loading problems with sabot/bullet combinations appear to live in areas that have more moisture in the air. The BP cartridge guys know that blowing down the barrel to add moisture helps to keep the fouling soft with real black powder. I wonder if the amount of moisture in the air could be part of the problem or lack of problem here. Just food for thought.
