Looks to me the bullet at 0:26-0:30 Keyholing in the video? Anyone else notice it?

This has been discussed before in a separate thread, but bullets stabilize in flight shortly after it leaves the barrel, usually from inconsistencies in the bullet itself or the rifling of the barrel. That's most likely what you're seeing. Did not know and sorry for posting it but thanks for the information thought I would share!

Also, remember its a full auto 74, so it has had mag dumps through it and more than likely wearing out the barrel. |

That's some serious fish tailing going on there. That round is designed to be unstable but not like that. Vickers puts up some good videos. This. A bullet key holing in flight like that means it was under stabilized from barrel twist. It should not do that in air. A flyer should not be key holing. |

I repeated the "this is normal and will stabilize" line from above in another forum.
Geeze you'd have thought I slapped somebody's mother based on the reactions! Let's just say the the majority of the folks from that other place hold a different opinion and tend to believe the barrelin the above video is toast! lol |

I saw this video before... Im glad someone else is pointing that out. I thought it was my imagination or something.
That looks (to ME) like its far more than just an unstable bullet. By the end of the shot it looked like it was beyond the point of being able to become stable... but it wasnt a very clear shot either. That rifle has probably been shot to hell though. |

Hi, Watch a video of an 76mm anti-tank round leaving a barrel and it does exactly the same thing, but settles down fairly fast. The M855 round out of a 1-7" twist does the same at right out of the barrel. Spin stabilized projectiles need a short distance to stabilize. Regards:
