Uh ... Mike, you mean .38 Super, right? Packrat, have you mic'd the case length? Speer #13 shows .380 Auto at 0.6800 in (17.27 mm). .38 Super is way out around 22 or 23 mm and could be trimmed down to 9x19 chamber length, and ...

SAAMI says ...

.380 ACP ............ 21,500 psi
9x19 (Parabellum) ... 35,000 psi
.380 Super Auto ..... 33,000 psi

So the Super should work trimmed back, but it would be wise to stay away from the high end of the 9x19 loads when using that brass (unless the brass maker verifies that their brass will hold up). Might work.
