I've been using Hodgdon's H110 exclusively for my .30 Carbine Blackhawk and rifles (M1 Carbine). It's a great powder and there's plenty of data on its application with the .30 Carbine for both the rifle and Blackhawk.
I'd like to try something else in addition. Something not made by Hodgdon? What about Accurate Arms #9? Is there data for these powders for my application?
