Blue Dot will work, especially for plinking loads - it's just not the best.I find it is a good powder, but it takes a little more than some of the faster powders and you might run into a compressed load for hot 9mm rounds. There is published load data for pistol, rifle and shot shells, including all the ones listing in the OP. Primers are a different story; Since priming is more a one at a time type evolution and I only load large and small pistol, switching primers doesn't seem as big of a deal to me. It would be nice to have just one to deal with though!
