HS6 and Unique are good mid range powders for the speeds you are seeking. While I have played with the fast powders some in magnum cases I am more inclined to go with a somewhat slower powder than 231/Bullseye/Titegroup. Just my preference.
Mart,
I don't have any HS-6 or Unique, but I do have about 4lbs of Universal left over from 12 gauge 1 1/4 oz Pheasant loads. I was hoping to use some as a substitute for Unique.
