Pyrodex RS in my 12 guage and pellets in my in-lines. Cost is low as compared to 777 and my accuracy is right on. I see no reason to switch unless production is stopped and I highly doubt that will happen. I've had no problems with cleaning, it's a muzzleloader it's suppose to get dirty. It usually keeps me away from the wife for a few hours without all that nagging, so the more dirty it is I like it.
