Great Post Dave, it should be another one added to the Help Forum.
I shoot a lot of "real" black powder. I use to have two local sources but now Cabela's quit handling it. The clerk told me that it was almost impossible to clean. I said that while it got things dirty I found the fouling to be soft and cleaned up easily with soap and water. He said he had never heard of anything like that before!!! I didn't pursue the discussion any further. I wish they would require the clerks at these stores to at least learn the basics from a forum like this before spreading their drivel to the general public.
