There are two SAAMI specifications, .38 Auto at 26500 psi and .38 Super Auto +P at 36500 psi. There is no intermediate .38 Super Auto "non plus P," because .38 Super IS +P relative to the .38 Auto.
If I were to GUESS, I might say that the $87 +P Starline might be beefed up to be overloaded to Major power factor whereas the $82 brass is meant for standard loads, but still up to the SAAMI maximum.
But if so, then what do they mean that the +P is of "similar internal dimensions?"
And so it goes...
