Below is pictured an unknown 9mm cartridge. I picked it up at SLICS this past April, I don’t remember from who. Probably either from Gary Muckel, Jim Hamby’s bins, or from the woman in the corner of the show who had a couple boxes of rare special-purpose 9mm cartridges.
The total weight of the cartridge is a hefty 226.4gr, which is by far the heaviest 9mm cartridge I have as far as the 20 or so other cartridges I tried - hollow points, fmj’s, tracers, subsonics, etc… It is not attracted to a magnet at all, and the headstamp reads only “97”. Does anybody recognize the font of that headstamp? Maybe another Israeli subsonic?
