Power Pistol is the reason that I haven't yet gotten around to messing with SR 4756 in .45 ACP. It is a very easy powder to deal with, and it gives nice results.

That said, I'd think that 4756 ought to move the heavy bullets out a little better, at the higher end of the pressure levels. I've used 7625 lately with .45s and been real pleased with it, too. And - toward the other end of the .45 burn scale - Green Dot, too.
