I still like Unique so well for non-magnum revolver and auto pistol cartridge applications that I even put it on my corn flakes in the morning, yum!
I care not if it's dirty. I clean the guns after each use anyway. I feel that I know my way around Unique's "unique" characteristics. Unique gives me perfect satisfaction in a wide range of loads if used in medium to heavy charge weight applications. It's kind of dishwater if loaded to minimum charges in my experience with large extreme spreads and incomplete burning. It cleans right up if pressures are a little higher.
It's great at "half-throttle" in old revolver cartridges, low velocity rifle loads in old guns such as .32-20, 38-40, and 44-40, can build up a decently useful head of steam when used at full throttle charge weights in the Magnum revolvers, serves for shotgun loading and can even make good gallery loads in bottle-neck rifle cartridges.
If there hadn't always been Unique then someone would have had to invent it.
