Attached are photos of a cartridge I would like more information on.
The headstamp at top left and cartridge at bottom are the ones in question.
The other is a regular Fiocchi headstamped 7.65 Browning cartridge.
7.70 bullet (bullet, neck, head, rim measurements are the same as regular 7.65 Br.)
21.05 case length vs. 16.9-17.28 for regular 7.65 Br.
30.15 overall length vs. 24.6-25.0 for regular 7.65 Br.
Bullet ogive is different also.
Please send me any information you may have or find out about this cartridge.
The person I received this cartridge from indicated it was a experimental cartridge that was developed to provide a more powerful cartridge in in a non-military caliber in Italy.
