Both the 357 and 44 Magnums have had their SAAMI pressure limits reduced, be it CUP or psi.
Single shot/Contender data still adheres to the "old" limits.
As far as cases go, at least in 44 Magnum; I have cases from the late 60's early 70's of Winchester (Western) and R-P make that are far heavier and have nominally thicker walls than ones fro the 2000's, FWIW.
