I'm pretty fond of Hp 38 and Unique. I just bought an eight pound jug of HP 38 (that should last a while) and can use it in every pistol and revolver I load, 32ACP to 45 Colt. I also use Unique in a lot of handgun calibers but also use it in my rifle loads. If I were to be limited to just one powder from here on, I'd opt for Unique. Gp
