Universal is almost directly interchangeable with Unique. I have just started using it as a replacement for unique and am quite satisfied with the results. Check the Hodgdon website for load specifics, but probably 7-8 gr of Universal will do what you want and be much cleaner. I used 7-7.5 gr of Unique in .41 with a 210 gr lead bullet as my go-to load for a long time.
