That document says that Winchester discontinued the “Hiway Master” metal penetrating production in 1982, but the Hiway Master was from Remington and was discontinued decades before 1982. I don’t know that Geco ever truly imported their metal piercing cartridges into the U.S.? I have never seen a box in the U.S. - even in Tucson! Van Ripper’s all lead bullets were a gun-mag novelty, never used by any police to my knowledge; they may as well mention the status of Magsafe.
The whole Christopher Wallace (Biggie Smalls) assassination report from the FBI was riddled with errors with regard to ammunition and spelling as well: http://iaaforum.org/forum3/viewtopic.php?f=8&t=10818
