Clark, thanks for pointing-out the .38 Special cases that were made with thin base walls to accomodate hollow-base wad cutter bullets. Those definitely are different from +P cases.

So long as people are talking about TRUE +P pressures in keeping with the SAAMI pressure standard, I think the thin-walled versions of the .38 Special case will hold-up OK.

But, when people start thinking about approaching .357 Magnum pressures in .38 Special cases, especially the older 46,000 CUP Magnum peak pressure standard, then I think it is a very good idea to use brass marked +P rather than some mixture that might include one of those thin-walled wadcutter cases.
