In another forum I frequent, one of the posters reported that he had a box of .38 Special PGU-12/B he knew nothing about. He posted a picture of a full box, with cartridge headstamps of WCC 81. The box label said “50 Cartridges/.38 Special, Ball/High Velocity, 130 Grain, PGU-12/B /WCC81H041-058.” It is a white box, no mention of Olin.
My understanding was that all of the USAF PGU-12/B ammunition (72 million rounds) was loaded only at Lake City AAP during 1979-80. Was any loaded under contract later by Olin? Is there more to the story?
