AA#7 can do what you want; it isn't quite as load level sensative as H110 and works very well with heavier bullets in 357. The new load data by AA is a bit conservative compared to 2 years ago, let alone 5 years ago. It is also far less flashy than Blue Dot.
Longshot is another choice that can give you what you are looking for. Another Blue Dot speed range powder with much less muzzle flash.
For a little more giddyap with lead, Herco does outperform Unique especially in the heavier weights. I'm not sure how much cleaner the new stuff is compared to Unique as I am using up the last of some old version I have. I was not impressed with the cleanliness I experienced with the reformulated flaming dirt.
Just my observations.
