Question about a 38 spl cartridge

Hello, I came across a few 38 spl cartridges. They are headstamped
W C C 88. The bullets are round nosed FMJ and weigh 130 grains. The powder weighs 5 grains. What is unusual is that the bullets are seated
deeper than usual, with an OAL of 1.336. Any info on this round would be appreciated. It Looks military to me. Thanks.


“.38Sp Ball High-Veloctity 130-grain PGU-12/B” cartridge used by the United States Airforce.
