The problem with "publishers data" is that many of the publishers have differing data.

Then you go the the powder website and that data differs as well.

and then you read older books and the data is much higher. Which begs the question: "Was it too hot back then? Or do we have lawyers covering load data now?"

Nobody wants to blow up their gun. But I (and others) would like to see what a 38 special can do....experiment. Maybe not to an Elmer Keith level, but you get the point.
