I load extensively for both. Unique or AL20/28. They're virtually identical and in my experience data can be interchanged. Velocities will run at most 3% higher with 20/28.
ETA- In the .44, 6.5 grs. of either powder with a 250 +/- gr. cast bullet will net around 850 fps and has been crazy accurate in every one of my Specials.
In the Colt 8.5 grs. with a 250-255 gr cast will get you 850-900 fps and has shot well in my Uberti and my Ruger NM Vaquero.
