While going through some 7.62 Nato rounds recently, I found this. Can anyone comment on this? The neck crimp looks relatively well done and is uniform right the way round. There was a comment on another thread dealing with fakes that sometimes the ballistics seems wrong. This “bullet/experiment” has very little weight, so it would seem from a ballistics point of view that it would start tumbling as soon as it leaves the barrel and encounters any turbulence.
