Something funny with data. I have not found any good cast boolit data using Unique past 120 grains or so. Alliant lists the soft lead Speer swaged job at 6 grains as a max which is surely well below the SAMMI limit as a 158 GoldDot is rated at 7.7. I would imagine it would be safe to go to at least 7 grains with a ~160 grain reasonably hard cast boolit. Anybody have better data or quickload or something?
