Question for those much more experienced in reloading than I am. I have been reloading for .308 and recently decided that I wanted to put the money savings towards shooting my wheel guns, but have ran into a problem. Digging through my reloading manuals it seems that the powders that could be used for both 38 special and 357mag are, you guessed it, impossible to find. The ones that really stuck out to me were unique, Blue Dot and Bullseye. Is there maybe a powder that I have looked over that could be in stock somewhere, or is powder interchangeable for these calibers nonexistent right now? Any input would be AWESOME as I would like to start making my own revolver rounds to get them out to the range more often!
