Welcome to the forum.
I've not cast those, but in a 24" barrel, a case nearly full of Trail Boss, say, 15 grains, should do just about what you want by getting to 1600-1750 fps or so. Given the individual nature of guns and not knowing the length or condition of your bore, YMMV. I will point out that Elmer Keith developed the .44 Magnum with bullets that were 16:1 lead, tin, or about BHN 11. So you have more hardness than you really need. That means it may have trouble bumping up to bore size, so I would try sizing the bullets about 0.002" over groove diameter (0.310") instead of the usual 0.001" over groove diameter, just to be sure you get a good seal. An extra thousandth often hits best accuracy with harder bullets, especially in lever guns and revolvers for some reason.
