Either I or friends get good to excellent results in 44-40, 44 Mag cases, 45 Colt for WAS with the following powders. Green Dot, Blue Dot, Unique, IMR SR7625, Universal Clays, and the powder you are already using. Titegroup has worked poorly in our revolvers but OK in rifles. Red Dot, Clays and Bullseye are OK but you have to be carefull about overcharging, especially double charging, with these fast powders. All these powders give poor results if loaded too light -- stick to loads above the mid-point of "Cowboy" loads recommended by the powder manufactures, or, often better yet, above the minimum regular loads they list.
In any case, get your loading data from a reputable manual NOT some BB on the Internet.
