I cast all of my own 44 bullets too, and i mostly use a RCBS 44-250KT mould. I cast the bullets useing wheel weights that i add in a bit of pure tin to get the hardness to where my thumb will just scratch the finished bullet... I make up "lots" of this alloy useing an old castiron dutch oven on an oldpropane burner.I then cast 2 lb ingotsto beused in my RCBS lead pot. I lube the bullets with ALOX and size them to .430 and i have no leading at all.
Useing the above bullet over 23.0 of H110, over the years i've won more long range pistol matches than i can remember and i also use the same load for big game hunting. I just don't have a need to push my bullets faster than that in my 44's.. (aprox 1300 fps)
This certainly isn't asecret recipe as i've seen many others post on the net that they are useing the same load and are also haveingexcelent accuracy in their revolvers too... I have tried 2400, 296, 4227 and several other powders but always came back to H110. It shoots so good ino longer even try anything different.
For light loads i use unique...
