I'm relatively new to reloading, about four years under my belt, and gave up on Unique after trying one pound. It meters poorly, burns dirty, gives large ES and SDs, and was position sensitive in my testing. I didn't find any redeeming qualities.

I like Trail Boss for regular .38 special, Power Pistol for .38 +P and .40 S&W, and 2400 for .357 magnum. I also tried Unique in my 12 gauge and was unimpressed as well. I use Red Dot or Clays there.

It may be a jack of all trades powder, but in my experience, it is truly master of none. I strive for excellence in my loads, so Unique was not replaced when it ran out.
