I have loaded it, but rarely shoot it anymore. You can use 38 Super dies (doesn't look like it should work, but it did for me), and start with 9mm Luger starting loads. If they won't reliably cycle the action, work up in small increments until it does. Stop when your MV reaches 9mm Luger levels - the pressure will be lower than for 9mm Luger by virtue of the larger 38 Steyr case. You could probably go higher, but I never saw any reason for that.
