I have been shown this 7.62x51mm with an odd looking bullet. The case is headstamped HE 7.62 with a flat brass primer with a ring crimp and green annulus seal. I show a typical military 7.62mm cartridge alongside for comparison. This one also has a flat brass primer with a ring crimp and green annulus seal but a headstamp of GF 7.62 (GF=1976 I believe).
On the suspect cartridge the forward part of the bullet ogive appears to have some file marks as if it had a longer, sharper, tip which was cut back to fit the normal O.A.L. Both rounds are completely non-magnetic. The bullet crimp on the suspect load is smooth, not segmented like the military one.
Any ideas out there?
