How were .38 Super Auto cartridges (without box) made to be distinguished from .38 A.C.P. rounds when first introduced, if at all? Were all Super loads made in nickeled cases from the beginning? I have been under the impression that nickeled cases were used for this purpose at some point (and more modern loadings of the Super are marked “+P”) but I have no documentation of this. Can someone walk me through the basics of this?
On the topic of “SUPER”, when the “SUPER 38 SPL.” headstamped cartridge was discussed recently, it was suggested that it was a confusing use of the “SUPER” label on the .38 Spl. High-Velocity as there was a .38 Super Auto also on the market. Perhaps its application, being shortly after the introduction of the .38 Super Automatic, was an attempt to set a standard for the term as applied to the new high pressure rounds being developed that would not be suited for older guns? (You have your regular .38 Auto and a .38 Super Auto. You have a regular .38 Spl. and a Super .38 Spl.) But why then have I not seen a .38 Super Auto cartridge of that vintage with “SUPER” in the headstamp?
Thanks for any input on this.
