Except for the safety aspect , light 357 mag. loads being mistakenly fired in a 38 special revolver , you could light load 357 mag or load +P loads in 38 special cases ...just depends on how light / heavy we loading them and how many 38 specials you have !

In the past I have loaded 357 magnum loads in 38 special cases with the Lyman #358156 cast bullet crimped in the bullets lower crimp groove...it was designed to do this . The longer loaded round is easy to spot if you pay attention to things . I never tried to load any in a 38 special .

So it can be done...but should you do it...No , just buy 357 magnum brass and light load them .
You can load 38 special +P loads in 357 magnum cases and not have to worry about wrong ammo finding its way into a 38 special.
