I like the same assortment of Unique loads listed above, and have reached similar results as already posted.....so I won't rehash those
I bought two big jugs of military surplus 10B101 powder....and my 41 loads really started to shine....
Here are the two loads I worked up for the 10B101

WW cases WLP 215 grn SWC boolit
Redhawk...11.5 sooted the outer 1/4 of the cases, accuracy was so so against my steel target
13grns all bullets struck steel at same place, not much unburned powder, no soot on cases

Model 58... 11.5 no soot, some unburned powder, POI was right on with fixed sights, feels just a
bit milder than "police loads"....I like this load in my 58
13 grns...felt like police load, similar accuracy....not as much unburned powder.
All ejected empties fine, just fell out of the revolvers, primers look good...
My Uniflo measure seems to like this stuff.(using the rifle rotor)..(weights) were very consistent-
