1-What are your go-to powders for 300 Blackout?
2-Do you usually use the same powder for Supers and Subs?

I have hundreds of the Hornady 150gr SP from promos that I can load for plinking, and may as well figure out a load to stack deep. Right now I'm eyeing H110 and Lil' Gun for Supers and CFE Black for subs.
