I ran per the Lyman Cast manual, 7 grns of Power pistol which should give you around 1173 fps or so. My favorite was the 38-40 bullet, which was deadly on pins. I ran both a 610 and a 1006
I don't use 10mm/PP for pins but I load up 8gr of PP under a 180gr XTP for use in my Delta Elite and I get right at 1250 fps using a Schuemann AET barrel.
