Nice, especially that wadcutter!
I had worked up a load a while back in the Russian case too. I ended up with 5.0gr Unique under a cast 250gr SWC, velocity was about 830 fps, right in there with the old ball 45ACP.
Some Russian rounds alongside some 44 Mag loads.
I was halfway expecting accuracy to suffer from the longer jump, but that was not an issue. I don't seem to have any target pics onhand to share though.
I wasn't too sure in the 44Mag dies would work with flaring/crimping the shorter case, and I just bought a dedicated set of Lee 44 Russian dies.
