Below are pictures of a box for Remington 9 mm Extra Long primed cases. The “Extra Long” is there designation for these 1.1268" (28.60 mm) long cases. Measurement is approximate, as the 50 cases in the box have been turned into 9 mm Luger blank cartridges, and the overall length was the length of the finished blank. However, the fit of the cartridges to the box would indicate they have retained most of their original length when they were primed-empty cases. I have no information who actually loaded these particular cases, since the blanks were reboxed in the original primed-empty case box with no added labels.
I just found the Remington factory designation of “9 mm Extra Long” to be interesting. Of course, if available to the public, these cases could be used to make many different 9 mm case lengths, such as 9 x 21, 9 x 23 Bergmann, 9 x 23 Steyr, 9 x 25 Mauser, and even 7.65 Luger and 7.63 Mauser/7.62 Tokarev, as well, likely, as many others.
Pictured next to the top view of the box is a finished blank from that box. Primer is with a nickel cup and no seals. The rosebud nose crimp has five lobes.
