My Hornady 7th Edition says...

.38 Special
Max 4.4 grains of Win231
850 fps.

Generally, when I want an in between load in .357 I find a powder that's listed in the .38 special +P data and add 10%, careful not to exceed the .357 data for the same bullet and powder.

That way, I'm only guessing at the velocity, since I have a upward bound. If I don't have data for that powder in .357 magnum, then I don't do it.

Bonus...no crud ring left in the cylinder when I'm done.

If I suspected that I might be loading a magnum load in a .38 Special, then I'd switch to .357 cases.
