I must have misunderstood what you were trying to say.

You did. I ****caned Unique because is burns so dirty and started using 20/28. The last time I looked there was no handgun data for 20/28.

For a great many years I have used a home-made cardboard baffle in my Lyman 55's powder reservoir. I have no weight inconsistency problem using Unique and Bullseye in it. It gives a constant powder head at the rotor, and that is what you need.

"With the #55 powder measure, the shape of the chamber in the drum can be changed; for example, narrow and deep, wide and shallow, and everything in between.
Setting it to where the opening is about as wide as it is deep works well for me with pistol powders.
Find the right drum chamber width/depth ratio, and it'll work fine."

I also go along with that. That's what I do.

Unique is cleaner now than in the old days. it is dirty for sure but a truly versatile handgun powder!

I have found that small charges of Unique can be problematic, but with charges of 6 grains or more, it meters reasonably well. The new formula Unique is cleaner than the original, but you still need to load it to at least medium pressure levels for it to burn efficiently. This is true of most powders.

This. Can use unique across wide variety of calibers, and widely varying purposes. While it is not at it's best with low or very high pressures, I could get by with unique for most purposes. Excluding high velocity larg bore loads with heavy bullets.

I use a Redding powder measure with unique and never have any issues just pay attention to what you do and be consistent,I also check every 10th throw just to be on the safe side

I had some trouble with Unique in an RCBS measure, but after I got a baffle for it I had no more problems.

My first reloading manual was the Lyman 45th Edition. It was 73 and I was fresh out of the Navy. The guy in the gun store said Unique would load all my handgun calibers from .32 Long to .44Mag and both of my .45s. It was two years before I bought a different powder and that was 2400 for all three magnum calibers. I use a lot of different powder now but I still think in terms of Unique, then decide how much of PP or whatever is appropriate.
