I use Lee 44 Russian dies to load both 44 Colt & 44 Russian. I have one set for each. Real 44 Colt brass requires a different shell hold than the one supplied with "Russian" die sets. I also use a Lee 44 crimp die (one for each set) - all together, has saved a lot of time making adjustments. I use around 19 gr FF in Russian cases & 25 gr FF in the Colt. A friend gave me a pile of 44spl cases long ago & one winter, I trimmed them all to 44 Colt length. Work fine in the Uberti RMs, etc.
For bullets, I use a first generation big-lube 200gr sized to .430.
