Unique is the "jack of all trades-master of none" pistol propellant. Granted, it does a whole lot of things pretty well. That said, it is almost never the Best for any one particular application except being good at a lot of things. It meters miserably and the original was pretty dirty although the newer formulation is said to burn cleaner.

It is what it is and many folks are in love with it for that reason. Have been for a long time. For my part, not so much.
