The Hodgdon #26 load manual from 1992 lists the max charge of HS-6 under a 158gr LSWC bullet at 7.3gr for a velocity of 955 fps and 19,200 CUP. My charge of 7.0gr HS-6 is not the max charge and that's from a reputable source.
Additionally, some older Winchester manuals show loads for W540. It's known W540 = HS-6 so when I saw the data listing 7.2gr W540 under a 158gr LSWC being just under the 20,000 PSI SAAMI limits I knew my 7.0gr load to be safe. Another reputable source from before the merge of both companies.
You are correct, you should always verify all data you get from the Internet from people you don't know.
