Have had the best luck with RL7 in the 38-55, but have found loads with other powders that were just as good. It just worked out that the loads listed seemed to work well in more than one gun. Your loads just show that to get the best for an indivual rifle a little adjustment may be required. I forgot to mention that the pyro and black loads were thrown in just in case some one wanted to try them. I know from experience the cleaning up a lever rifle after shooting them takes all the fun out of making smoke. But in a single shot rifle they can be a hoot and surprisingly accurate.
