In the .357 Magnum data with a 158gr LSWC bullet they say the max is 7.0gr of HS-6 with pressures of 15,500 CUP.

I find those numbers to be strange. The .357 Magnum case is only slightly longer yet .7gr more powder generated less pressure than the .38 Special. That is hard to believe. Also, only 15,500 CUP in a .357 Magnum round, not hardly a Magnum, is it?
Yes; looks like they didn't complete their work.
