I used ro use it a lot in .41 Magnum and .357, but quit when Speer quit selling the half-jacketed bullets for those two cartridges. It was/is dandy stuff. I even used it in 9mm and .45ACP for some applications. At the time, the only two powders I kept handy were 231 and Blue Dot, as I was living in a barracks at Ft. Bragg, and din't want to keep a lot of stuff around. They weren't the best best powders, but they worked in all four cartridges well enough.
The .41 was an eye-opener with it, though. The first ammo I shot in the new Blackhawk were 220 Speers and Blue Dot, and I was able to hit milk jugs at 100 yards easily, I hit four of five with the first six shots out of the gun. Ah, the good old days when I didn't have arthritis or bad eyes.....................My favorite .357 load was the max charge of Blue Dot and the Speer 146 half-jacketed HP, it was spectacular in the old Smith M28.
