Would be grateful for any ID, or background information on the following:
Bullet diameter: 8.00mm
Case length: 53.40mm
Total length*: 75.05
*The cartridge is inert and has, at some point been pulled, therefore; the total length may not be a good indicator.
Headstamp: FAMMAP (Fábrica Argentina Militar de Munición de Armas Portátiles, San Lorenzo, Argentina.)
Bullet is highly magnetic.
Any help would be greatly appreciated.
