Unique
I reload all of your listed calibers, plus a few more (380, 9MM, 38, 357, 40, 41, mag, 44spl, 44 mag, 45acp, 20 ga) and have bought them all (hs6, bluedot, 2400, reddot, greendot, promo, titegroup, hp38, bullseye, AA2, 296/110, longshot, WSF, herco, clays, universal clays, 700x, 800x, and more that I can't remember. Of all these powders, the most accurate accross the board with the broadest application (lead or jacketed) is UNIQUE. I wish it was not true - this is an old powder that should have been forced into retirment by some new high-tech powder. yup its a little dirty, not always the highest velocity, meters so-so, looks plain. There seems to be an accurate zone for just about every major caliber with Unique. Sells for $98 per 8 pounder. Rant over.
