I just officially gave up on loading the 32-20. Extreme spreads can be downright ridiculous.
My 5 1/2" Uberti was pretty good, only occasionally giving extreme spreads in the 100-150 fps range. It's a hoss of a revolver with super thick cylinder walls and digests heavy loads with ease, but it's a heavy revolver to lug around.
I recently bought a S&W Hand Ejector 32-20 for my young grandkids to shoot and it's the most frustrating revolver for which I have ever loaded. Even hand-weighing each and every charge I often had ES's over 200 fps. They were so bad at times that I could tell by the report and recoil of the revolver, without even looking at the chronograph, that a particular shot was much faster or slower than the others in the string. I tried around 50 different loads experimenting with different powders (IMR Target, 700-X, HP-38, Longshot, Unique, et al.), bullets and small pistol, small pistol magnum, small rifle and small rifle magnum primers. Most of the loads with acceptable ES's were light charges of fast burning powder.
So I decided if the best I could do was a 750-850 fps with 90, 100, and 118 gr. bullets, I may as well be shooting a 32 S&W Long. So I just got a little 4 1/4" I-Frame Smith in and will soon have a 3 1/2" HE. AND I won't have to lube cases anymore!!
