Hey there handgunners,
Well now, this just may be my opinion, but reading the post gives me the feeling that AA #9 is in disfavor for the simple reason that it is tested by very few shooters.
Back when I had a BH Hunter w/2xLeupold, I went through a number of powders looking for "THE" one. Tried the old standbys, 2400 & 110, tried 296 because a friend thought it was pretty good and gave the newer kid, AA#9, a try.
That Hunter ended up shootiing groups at a 100yds. (with two witness)which are too small to mention. And the powder is ---------- AA#9!!!!!
It IS a good powder, every bit as good as the 2400, 110 & 296 and in that gun BETTER! Plus, it will more then likely meet or beat the velocity of the other listed powders.
I was impressed enough to to buy 8lbs. of the stuff, and have never seen any reason to change.
I have used this powder behind a 310LBT and a Lyman bullet which went about 345gr.
The Lyman mold was out of their reject list, and cast much heavier then the 325 it was listed at. That reject mold was also the mold used for the great groups.
Give it a try, don't think you will be sorry.
Keep em coming! :wink:
