I've been reloading close to 50 years and this is my method for plated bullets , I look at two things:
The starting load for jacketed - Hornady 8th Edition- 5.7 to 6.3 max.
Then the starting load will be 5.7 grs. HS6
The middle load for a cast bullet. Lyman 4th Edition 5.0 to 6.3 max.
5.0 + 6.3 = 11.3 divided by 2 = 5.65 rounded off = 5.7
Then the starting load will be 5.7 grs. HS6
After looking at both published sources , it seems 5.7 is the place to start. I would load up a few rounds and see how they shoot. Experience has shown most loads might be fine right here or need an additional powder charge of up to 0.5 grain to get proper gun cycling. Test it out first. Use the lowest charge that insures 100% cycling of the gun with acceptable accuracy.
You didn't mention any reloading manuals , buy at least 4 . That way you can cross check information . Lyman and Lee cover cast bullets . Hornady and Speer are my other favorites. Lots of great information in them besides the Load Data , read them , they will become your friend's.

Reason: divided by 2 = 5.65 not 6.65
