I just aquired three cartons of original Kynoch 9,5M/S cartridges. Or so I thought. There was one cartridge that didn't fit in with the rest of the bunch. It's a DWM cartridge, with what looks like a steel/nickel jacketed bullet, shaped somewhat different from the Kynoch bullets.
I've been using my google-fu all night trying to find some information on these, and from the headstamp I have determined that most likely the cartridge was manufactured in 1929, and it is indeed a 9,5M/S cartridge.
Other than that, I found a lot of information on a variety of DWM cartridges, but not much at all about them in this specific caliber.
Are these cartridges rare, and does anyone know how long were they produced? Do they differ from the Kynoch cartridges in any significant way?
Just curious since I didn't know these existed until tonight. Anyone?
