I use Winchester Super Field ("WSF" in the manuals) for my .45 and 9mm.
5 grains of Bullseye and a 230 grain ball projectile. If it's good enough for Uncle Sam, it's good enough for me.
I've always used Unique or Bullseye with my single stage set up.Bullseye will meter easier in most measures and you'll get more loads from a pound.The trade off is it's better for target velocities while Unique will give you full power loads.
