I have several that I really like, and by nature I don't have anything that is dedicated to just one thing. But if things get stupid like they did in 08 with the stockpiling and shortages, one fall-back powder to run everything is a good thing. Since I cast for nearly everything I shoot, I have a Red Dot load for everything I cast--rifle and handgun.
