[QUOTE="Fiftydriver, post: 107166, member: 10"] I have tested it in some really large capacity, small bore rounds with case capacities up to 110 gr and while WC872 does produce a bit more carbon fouling then say Retumbo, it has never proven harder to clean out of a bore. One thing to keep in mind is that this powder, just like old 870 will produce extreme powder fouling at lower end pressures. The higher the chamber pressure used with this powder, the cleaner it will burn. If your running lower pressures, you will be better off with the stick powders. The different smell is probably just a single based powder compared to a double based powder. Even at top end loads though, you will see a bit more powder fouling with WC872, just as you will with H-870 and I suspect the new US869 as well. Just seems to be a characteristic of ultra slow burning ball powders. Keep the pressures near top end and she will burn as clean as possible. Kirby Allen(50) [/QUOTE]
