I use Unique. Choose this because I had load data in my Lee manual for 9mm and .45 ACP. Also I like to use a powder so that the load fills up more than half the volume of the case so that it is impossible to double load. I also wanted something that was easy to find. Unique fit this for my pistol needs. I also use Varget for my .223, .243, 30-06 for the same reasons. This way I have two powders for everything.
