I just bought a new 6" stainless Ruger GP-100 in .357 Magnum. I have a little powder on hand but only about a pound of W-296. I also have some Unique, Power Pistol, Blue Dot, Universal Clays, No. 7 and Titegroup. I was hoping to pick up a pound or two of 2400, No. 9 or H-110/296 for loading the .357 Mag, but there doesn't seem to be any available locally. The local Sportsman's Warehouse (formerly Wholesale Sports) does have a couple of 8 lb kegs of Unique for a good price ($119.99). I know I can load the .357 with Unique, and I feel that is a very good deal, but I would rather have a slower burning powder for the top performance with 140 and 158 gr XTP's. Should I grab the Unique knowing that it is decent with lighter bullets, and be set for a while with cast bullets, or be patient (never my strong suit) and wait for a better .357 Mag powder to become available? I also load 9mm, and .45 ACP so the Unique can do triple duty, but of course those can also be loaded with my current stock on hand.
