I never check into figures that are irrelevant 38 cases are much thinner & designed for up to 20 psi 357 mag cases are much heavier & designed to withstand 37500 psi so loading weak low power loads in 357 cases makes it harder to seal off the case & get good seal in chamber...in other words
LOAD 357 loads in 357 mag brass ....load plinking loads in 38 brass
No reason to complicate it more than that.
I simply seat cast Bullets in crimp grove as well & shoot them at the length they are
This is not true with modern 38 Special and 357 Magnum brass. The cases are coming off the same machines made to the same dimension except for the trimmed length and stamp on the case head.
Top to bottom: All Remington nickle plated cases, 357 Mag, 38 Special +P, 38 Special. There was less than .010 variation in case head thickness between the three and the web was exactly the same thickness.
