Just for fun, I ran one of my known .357 loads thru QuickLOAD and substituted Alliant 2400 for my AA#9. Not posting results, as QL is not at its best with straightwalled cartridges. But on a comparative basis, projected pressure and velocity were essentially identical.
I load both AA#9 and H110, with #9 about 20% lower by weight. Mostly Accurate, though. I get slightly better consistency.
PS: Powder Valley, for one, has 2400 in stock. Sure ain't cheap though.
