While I love this kind of stuff (as my hands get older, I've come to appreciate slow speed, low pressure big bore stuff, why not just use Trail Boss powder with your 44mag brass? If I recall correctly, my mid-level TB loads with a 250gr SWC are running about the same velocity as your 44 Russian loads. I could go lighter or heavier with that powder and bullet combination.
Though, Trail Boss powder is probably less available than 44 Russian brass these days.

Yes Starline has some last I checked.
I am loading a bunch to sell to people locally* and I had the Titegroup on hand. Powder is incredibly hard to get, just like primers, and most new brass.
* I have a class 7 manufacturing license but don't really discuss it here as I have not advertised here. Plus I manufacture on such a small scale that I really don't want to put out a big ad online as I could not keep up with demand for stuff due to the current crazy ammo shortages.
If I had Trail Boss in large quantities I might try that but I think I have less than 2 pounds of the stuff.
Covid shutting down everything, including my work and my kids schools forced me to have to rethink what to do to pay the bills. I have been loading ammo for about 30 years, so my "side business idea" became a full time gig. Plus it gives me an excuse to travel less, be home for the kids each day, and play with guns that I actually like instead of issued type weapons. M29s are more fun than Glocks for me.
Now if I could only find a large source of primers....
A while back a buddy who has been cast since the Middle Ages and is one of my Go-To guys for all manner of questions on cast bullets, reloading, .38 Supers, and other subjects, sent me out a few hundred of these.
They are about 165 grains.
Without changing any settings on my press from the 240 grain round nose load, I loaded up a handful. They mushed the noses flat a little bit, but the seating depth was not bad. I am planning on shooting them to see what kind of accuracy I get, as well as velocity, just for kicks.
Funny looking little things.
Oh great!
Now I want to order some brass and load up some Russian Imperial Stumpy ammo for my Mountain Gun.
Any idea how they feed in an 1894 Marlin with an appropriate bullet profile?
Are you using .44 Mag/Spl dies or something else?
