I ‘m trying to identify this cartridge for a friend! He has approximately twenty boxes of this ammo packed in what looks like original plain white cube shaped boxes with no label. I did a little research looking in reloading manuals and on search and could not find a match. This cartridge is shorter than anything I could find. Please review the dimensions list and the attached pictures.
