Alliant's .38 Special data has come way down over the years.
They and Hodgdon also use ridiculously long barrels in both .38 (7.5 & 7.75) and Hodgdon uses 10" in .357.
I think they do this to show higher velocities while user the lighter, safer data. Most people choose data on velocity, and with both of their online data resources they do not show the barrel length.
I just looked at my Speer #10 & #11 .38 data, widely regarded as safe. Their write up says the .38 Standard loads are held to 18,900 psi and the +P are held to 22,500psi.
Today the 18,500 is the +P standard.
