Use the "general purpose" recipe for TB loads for light rifle cast bullet loads!

See:
https://www.hodgdon.com/resources/data-sheets/
and punch up the Trail Boss light loads.   

That should get you to:

Follow the 3 steps to figure out where to start.

Good luck, GJ

But my best cast bullet loads with 8 Mauser is with 5744 - I push the 170 grain slug at about 1550 FPS in my Yugo 24/47.

Good luck, GJ
