Will second V8's.... 8-10g of Unique. Somewhere in there,you're going to find a very nice balance of, X ring accuracy,power,and shootability.
One other "area" of loading is,lighter loads using faster,typically bullseye target type powders. Be careful not to go too low(sticking bullets)...... but some of these "target loads" can be stunning. I'm sitting on a LOT of 700X powder. And ain't hurting for lead supply,or moulds. With some judicious tuning/testing, my 44's can tear an X ring up with very mild recoil. You don't hear about target loads out of 44's much anymore,but there was a day when they were king of the hill on accuracy. It can really do wonders for your revolver shooting..... if say you wanted to go big game hunting,with more power in the Fall.
Good luck with your shooting,nuthin better than seeing someone tearing up the X ring stroking a 44.
