OK, I decided to go back to good ol'e BP in my .50 TC recently. (I have used Pyrodex RS for about 10 yrs) went ot buy some and could not find it. I had every excuse from "didn't want to do all the paperwork" to "gotta have an underground bunker now" As usual now days i went on to settle on something else. looking at the shelf i noted a couple of ohter Hodgen products LUCKY SEVEN (i think) and Hogden select. dealer couldn't really explain the difference in the $5 price difference except for better. Huh? I know there are potential ignition issues with exotic powders and non-inlines. so i stuck with Hogden RS. I'll still look for the BP in my travels.
