If you look at Speer #11 for 357 magnum they list the max pressure as 46000 cup. With a 125 grain bullet the max load of Blue Dot is 16.3 grains.

Speer #12 has 35000 psi and 13 grains.

In the 90's a buddy bought a 4" barreled GP100, a stout 357 for sure. He asked me to put together a few rounds for him so I did, to the older spec of course. When he fired the metal roof over the firing line sang for a bit. To this day that load is known as The Roof Ringer.
