Mr. Hoy us right, full loads are fierce. I'm not crazy about reduced loads with cereal as a filler, I used count chocula with mixed result. I wonder if 45 S&W brass mght be better for reduced loads. I use lubed wads in my C&B occassionally because they get loaded and shot. I worry that the lube will migrate into the powder in cartridges that sit for a while.
I used full pyrodex loads in a '73 win. copy with a fiber wad and dar formula lube. I have to clean powder fowling after but never noticed any leading.
