Yep, for full power you can't beat H110 or 296. Also VhitaVouri N110 is right in there. For almost full power with greater flexibility, 2400 or Blue Dot. For midrange stuff, Unique or Universal. For lighter loads, there's a bunch but my current favorite is Titegroup. That's the beauty of the .44 - you can use anything between Bullseye and 4227 in it, depending on what velocity level you want. Just make sure you stick to book loads, it's easy to get carried away with the faster powders.
