I had another thread on a particular loading for the .357, reducing it down to say .38 +P++ levels.. But, why not the other way? If you are loading .38s in a .357, it is the 35,000 psi you care about. So, if you use a .38 case and fill a load that will give you 30,000 psi but load it in a .357, you won't harm the gun itself,, right? But what about the case? Other than the 1/8 inch in length, is the case for the .357 also thicker? What pressure is the .38 case rated for?
