BECAUSE IT HAS BEEN FIRED THIS ONE IS DIFFICULT TO ID - THE NEAREST MATCH IS M&M 323 - .72/.73 CALIBER FOREIGN RIFLE. LENGTH 1.00, DIAMETER .69/.72 (OVAL), WT. 750 GRAINS, CAVITY 10/4 OR 11/4 (VERY DEEP). I WOULD NORMALLY NOT LIST A FIRED BULLET IN THIS CONDITION, BUT ASSUMING IT'S 323, IT'S A SCARCE ONE.
