I've been quite happy with Carnauba Red and Power Pistol using the same mold you have. Higher charges seem to be less smokey, but the lower charges help with the quicker transitions during Steel Challenge. Lower charges were less smokey with HP38, but Power Pistol seems to work my compensator better. PM for actual load data.
My barrel is only ever one swipe from clean, and the only time the chamber gets fouled up is if I use too much case lube in the case feeder. I was never able to get 45/45/10 to stop leading, despite the ease of use.
Another thing that might help it smoke less is to go up by .001" . Get a better seal and you'll melt off less lube.
