I'm sold on the BH powder also, all though I still clean up after every outing. The TC Triumph and Firehawk require a wire brushing after the 2nd shot maybe a 3rd. Pretty tight bores on TC rifles. The Knight seemed to be slightly larger bore and maybe could get 3-4 shots before a brushing was required. This isn't any different than other powders like 777 but the BH just feels right and accuracy maybe is a bit better?
