I use Blue Dot and some similar powders for reduced rifle loads. Lately I've been using some Swede Gallery Powder from the wooden bullet loads. If you know what that is, great. If not, don't ask because it doesn't seem to be available any more, anyway.
The main thing I want to add is in regards to loading technique. I have tried the recommended "charge one case with powder, then seat the bullet" and it doesn't work well for me. With repetitive tasks like that I'm prone to zone out and then think, "did I check that last one?"
What works better for me is to charge all the cases, then check them all at once with a light before seating the bullets. That way I don't have to worry that I might have had an attention lapse, because I have a last chance to check them all before sealing them up.
