Mike, I was told by a friend who has fire-formed cases that it was his opinion that black powder gave better results. I don't mind the mess, if it is indeed better suited to the job. I knew from my past experiences with black powder that I wouldn't get into trouble with it. I have zero experience using reduced loads of fast burning pistol powders, or fire forming at all. Just trying to play it safe. I have read all my reloading life of the dangers of reduced loads possibly causing detonation.
I would gladly consider a smokeless load to do this, that someone had a safe and successful experience with in the past.
