If they were 158 grains, I would say 8.0 grains of Herco, or you can substitute WSF. Since your bullets are heavier you'd have to back off a little but I don't know how much -- maybe 7.2 or 7.5? Start at 6.5 or 7.0 and see what you get, and work up from there.

AA#7 is also good in .357 Mag. I get the same performance as with Blue Dot but without the leading.
