    I remember this. Not just crushed but Shredded. I wrote my Congressman at the time who was Chair of the House Intelligence Committee - Mike Rodgers R 8th District Michigan.
    I knew him as a member of the Michigan State Senate and as a Client before he ran for Congress (Painted his New Home). I went in to great detail about US tax payers having to pay for the shredding of the Brass, which was still offered for sale to the Commercial reloading companies, but useless in shredded condition. It was then being sold to China. On and on I went. I mailed a copy and Emailed a copy.
    Posted on the Forums about it. Much to my surprise Mike sent me a return Email 2 days later letting me know that policy had been changed and the Brass and any Surplus bullets that could be sold would be sold. 6 months later we were back at his house working on it as it was being upgraded. I really thought he'd run for President, but pulled out of Politics.
    He was 'Almost' the replacement after James Comey was fired.

    Back on Topic,
    When the shooter took what he called was going to be his last shot I seen much more Flash and that round went flying bottom right.
    Then...... He decided since he had that 1 round left he was going to make it his 'Last Shot'.
    Too bad he didn't save that last one and Displayed it.
    Didn't he question if the load may have been a Reload? And that he didn't know for sure.

    I was also under the impression that it was a really old round from his comments about it and the price per round before he started shooting.
    I'd have to watch again, But didn't he say when he called the gun maker they said it would take something like 80,000 Lbs pressure to strip the threads for the end cap ?

    Was up really early this am because the Coyotes across the river were partying. By mid day the sky was full of Buzzards.
    I Watched a few early morning videos with others giving their opinions why this gun failed. A few pretty much said what Tanker said about this type round not being antique. Some leaned towards it being a reloaded overcharge. One talked about how long that round may have set in that metal can in the hot sun.

    On a lighter note I also watched a video of US trainees on the firing range. 1 guy repeatedly pulling the trigger with no boom. His DI standing behind him asked (Loudly) if he was out of ammunition. Trainee replied "There's no way Sir". DI told him "Try inserting the magazine correctly" as it was in upside down. Trainee pulled the Mag and got it in the lower... pulled the trigger but no Boom. DI looked in to the camera with a WTF kinda look and told the Trainee to " Now turn the mag around" . Trainee turned the mag around and inserted then pulled the trigger again... No Boom. DI then mentioned "Try the pulling the handle". Trainee charged it and finally got off his first shot but shot at the wrong Target.
    No Blood, but I'd also call that a Bad Day.

    Thx All for for your input. I'll have to watch it again.

    Interesting case. The "estimate" of 85K PSI to blow the "breech-cap" off the threads is presumably based on the manufacturer's estimate of what pressure would cause the threads to shear off as they did. Actual pressures generated here are apparently unknown.

    I have to wonder if there was a more or less complete lack of case to chamber wall adhesion here. The best cause of that is oil or wax on the case or the chamber wall.

    With a mere three or four turns of plain old 60° thread to keep that cap on, I for one would never put my face behind it. The threads have clearly sheared near their roots, which raises questions about the steel used and the heat treating of it.

    At least an acme type thread might have been wiser, and more turns, but of course too many turns and guys get tired of it... An interrupted thread would have resolved that problem.

    Were the rounds perhaps tumbled to clean them up externally? Did someone assemble surplus components with the wrong propellant?

    He's a gutsy fellow anyway, and now a wiser one too.

    Plastic sabot. Perhaps it degraded with age or storage conditions and separated early from the second last round causing a barrel obstruction for the last round.
    Ovidio, you are always welcome for a range day should the opportunity to visit present itself.

    Thamks MSW2. I’ll reach out to you and Daan when the time comes.
    I decided to see the world and meet people more than I did before, when I just traveled the world, which is very different...

    I saw an article the other day where the bad guys are doctoring ammo and putting it on the market as surplus but its way out of spec say filling a 7.62 x 39 round with AP-5 of pistol powder so a massive over pressure is ensured.
    Would not surprise me that this is occurring.

    Working at the range 9 hours a day got painful wearing safety glasses and Howard Leight earmuffs. It was a GOD send when my wife gave me these Caldwell E-Max Shadows I absolutely love them. Can wear whatever shooting glasses I want and no cheek weld issues.

    Easy to do, and it was a government program. Here's how it was run under MACV-SOG
