That is the issue with reloading sometimes. There is 0 data for what you want to do.
In that case there are only 2 options:
Get a different powder and bullet combination that is listed OR 9If you are a long time reloader) work up loads on your own with lots of combined data and research to support the theories you have for loading that combo.
I have had to do it quite a few times, and have come up with some pretty awesome loads, and others just failed miserably
