At least he got it on video.
I have said this before. I plan on getting a .50BMG some day. Not too incredibly long from now. But I have seen horrific injuries from kabooms from manufacturers just dipping their toes in. Like the AR upper ones. When I get my .50BMG I'm getting a Barrett and nothing less.

Well I guess that settles it. We all need to make the sacrifice of going each weekend to the range, for the safety of each other.
I'm sure the wives will understand.

I'm sure the gun in the vid was just fine although I'm with you. I'd rather have a high quality rifle for something as powerful as 50 BMG. This looks to be the fault of the ammo which is yet ANOTHER advantage of reloading vs factory.
This was a Serbu. They aren't a low end name in the .50bmg community
Give me locking lugs over threads any day.
The ammo was an over pressured SLAP round, military surplus that appeared to have been tampered with..
It was not the gun at all

Darth,
The barrel is threaded to the action whether it has lugs or not so there you have 2 possible points of failure vs. one.
He got the warning at the first shot with that "experimental" round.
One could build it to take 100k psi but also consider one might be moving a possible point of failure from one point to another.
Bottom line, don't play games with "specialty"/"experimental" loads and specially because this is not going to be a "25 ACP" load mistake.
When in doubt, I have seen youtubers sitting behind a shield/cover and pulling the trigger with a string or something.

watch the video !!!!!
.. he tells what happened ... the gun is rated for 55K psi i think he said and the maker of the gun said to sheer them threads off
would be 80K or over ..
this is a breach loaded gun with a steel cap to lock the round in the chamber .. and the rounds we not experimental ..

could have been tampered with .. or just a whoops in manufacturing .. it got a double charge of powder .. will never know ...

i have pulled a 50bmg live round apart .. i still have the powder in a plastic container out in the shop .. very small ball powder .. and i bet it only filled the case 1/2 way .. plenty of room for a whooops double charge ..

Do you have a casing you could put that powder in to confirm it only filled half way? That seems like it could be a problem in and of itself.

i do have the case and bullet still .,. and the powder in a container that is way shorter then the case .. just cant put it back in .. kinda lol .. i drilled out the primer pocket so i could put it on my pony tail lol
brb .. out to confirm .. i have had this for like 8 yrs ..
found the powder funnel lol
i was wrong . at least with this 50 and power .. brb .. have to use the phone to add some photos

Could also be that the round has been bouncing around in someones trunk for 10 years and the powder had broken down
If it starts as ball powder and ends up as flake, it's burn rate is going *way* up.
This seems to be a myth. Ever see the experiment where the guy put them in a tumbler for an extended period?

To rule it out as a freak possibility it would take a lot more than one experiment.
When they (normally) test a new drug they don't just say "we gave it to one guy and he was fine, so we're rolling it out to 300 million now...."
And was your experiment done with *this* powder in a case *this* size ?
Or is this a case of "well, we tested the polio vaccine on one guy 70 years ago, so we're saying the covid shot is safe, because we proved back then that vaccines are safe".
This was one of the inherent flaws of Mythbusters. It is very difficult to prove that low probability events are impossible. You certainly can't just try them once and say it's good. "no, driving drunk is perfectly safe, I've done it 100 times...".
The myth of absolute certainly gets us nowhere.

I'd feel safe wagering 50 BMG has been treated worse than anything this guy good to or over the decades.

I'll wager the 100s of thousands of experiments showing that rifle model is safe is more convincing than the one experiment showing that the tumbling is OK.The myth of absolute certainly gets us nowhere.

That's the trick with low probability events. The odds are extremely low on them happening, but they do happen.
Your logic would say "that tumbler experiment shows powder breakdown is not the cause, and the hundreds of thousands (or millions) of rounds fired by Serbu rifles shows the design is sound and that their construction is top notch. The millions of those rounds fired by the miltiary show that they are also safe. So we have to conclude that this didn't actually happen"....
It's also possible for powder to break down just sitting there if it's old enough.
How long did it sit *after* that tumbling experiment ? Maybe that's what happened, it got bounced around for years, then sat on a shelf for a decade.

"To protect the resulting powder against autocatalytic decomposition, one of the usual stabilizers as, for example, the centralities or diphenylamine, may be added to the lacquer so that the desired amount becomes incorporated within the individual particles of lacquer (Olsen 1942). "
To say nothing of the fact that the massive case volume of the .50BMG gives a lot more potential for degradation than the smaller rounds he tested.
You can drop test your product at 6' all day long, that doesn't mean it'll survive a fall from 20'

I'm inclined to agree. Still watch what you feed it. The problem here seems to have been an abnormally and exceptionally hot round of surplus ammunition.

From the pictures the round was quite full. Maybe that's normal maybe not. If normal then maybe KB's issue was it was actually loaded with the wrong powder. Or maybe too much of a powder that doesn't take a full case to work. Double charge possibly. Possibilities are endless. Thanks for the pictures btw!

I have a hand held version if that counts.
