Odd 9x23


#1

Last night I examined new receipts and the unusual 9х23 cartridge noticed. Its bullet “heavier” than at the other. (In middle)

Headstamp “D M W” (?) What it for a cartridge?

The cartridge in the middle is a 9 mm Bergmann-Bayard made by DWM in Karlsruhe and those on the sides looks like 9 mm Steyr cartridges. Headstamps?

Your FN * rounds are 9 mm Steyr. The box labels are known. Oddly, even though I have researched the 9 x 23 mm family of cartridges heavily, I have found no evidence that FN ever made the 9 mm Bergmann-Bayard cartridge, odd since so many of the Bergmann-type 9 mm pistols were made in Belgium.
However, Anciens Etablissements Pieper and Cartoucherie Belge both made the Bergmann-Bayard cartridges, so perhaps that was enough for the market on them.
