Once upon a time I had trouble throwing consistent charges of Unique with a Uniflow and a Lyman 55. I bought a Redding #3 and that fixed it. When the Lyman DPS 1200 came out I bought one for Unique and one for 2400 and have never looked back. I save the Redding for powders I don't use so often, like bullseye, aa5, and h110.

I had a 10-5 with a 6" bbl that was gorgeous and particularly tight; 4.9 gr of Unique under (under, Erich) a 158gr swc ran 910fps out of that particular revolver. I have since run out of utility for 6" barreled .38 sp revolvers and gave them up. I've loaded 5 grains and better, but they're unnecessarily punchy for my current purposes.
