Anybody using W572 powder for 44 mag?

[Oldtown102]

Picked up 3 pounds of 572 at pre-covid prices and am experimenting with loading middle of the road cast rounds for a 44 mag revolver. The cases seem pretty sooty after firing and it blows a pretty good fireball shooting at dusk, but accuracy seems pretty good.

I don't think it was designed to be a full-up Magnum powder, at least that's what the data suggests. Like some powders, it might clean up as you increase the charge weight. It is a slower powder... near BlueDot, AA#7 and some others, so you would get a fireball in shorter barrels, most likely.
