In .44 mag, for "heavy" loads, I like H110, for lighter loads, Universal, for really light loads with cast bullets only, Trail Boss. I have both Unique and Power Pistol, but have not tried them in .44 yet. Have just started to use Titegroup in both .44 and .45 LC, and it seems to do OK with 300gr + Hard Cast bullets at 900 - 1000 fps or so.
