Originally I saw the popped out primer, but then I got attracted to the deep defect in the groove. It is smoove with no rugged edges and looks like the cartridge’s original confuguration (not something induced by the gun). Indian ammo has SOME reputation. Tailgunner wrote the following in a dufferent forum.
The OFV headstamp is used by the Varangaon Arsenal in Bhusawal india. I had some experience with couple of lots of OFV from the late 70’s in 7.62. My thoughts are I would not fire this ammo by remote control from the next county. I wouldn’t even pull it down for component. I would have someone perform an exorcism ritual on it and burn it in a deep pit.
So any thoughts about this ejection groove anomaly?
