I always liked HS-6 for the 9mm, or Herco, but HS-6 meters better in a Dillon 550. I used 7.3gr. with most of the various HPs you could get those days, Sierra, Hornady XTP, and Speers and Noslers. I was always a fan of Sierras, but the Speers feed a bit better. I also used AA#7, but preferred HS-6, really.
They shoot really good in Browning HPs, CZ-75s and Tanfoglio, a Polish Radom, and probably several others.
