While over pressure signs can be misleading or non existent there is one sure way to find out.

You must chronograph your loads. The velocity reading will be the best way to find out if you're exceeding the working parameters of the cartridge.

When your .38 Special loads are clocking as fast as the known velocity of the .357 then you know that the pressure is too high.

Anything else is just guess work based on observations of fired cases.
