Maybe I missed it, but why isn't he calling out the ammo manufacturer and warning people not to use that brand ammo?

I think He was saying that someone had to have tampered with that round to get the pressures High enough to blow the gun apart since the rest of the rounds from that same batch did'nt do anything .

Boy that guy must get a lot of free stuff or hes pretty wealthy to afford some of those toys he has.

I’m glad he used concrete rather than his face to cheek it this time.
You could tell he still doesn’t trust the rifle because he fired the first round (standard ball)
out of a new rifle,
from cover?
I think @ 190k psi would blow any rifle
Don’t think there’s any manufacturer to go after here. Black market shit

He was using the equivalent of gun show ammo sold in used Ziploc baggies. Who do you blame?

As far as shooting slap rounds out of rifles with a muzzle brake, It’s really not the best idea. Sending a .30 down a .50 barrel even the slightest misalignment of the brake..
It won’t end to good. For me it’s the lake city current production ball with the metal seal on the ammo case. The case capacity on these .50 bmg rounds alone scares the shit out of me. Maybe a reloader can chime in and tell me how the fuck they got to 190k psi for this test? I’m just curious. Scary shit man.

Fast powder maybe? Heavy projectile? Maybe a combination of the two. You need to match the burn rate to the bullet weight (and case, but that is usually the variable that has the least impact). If all the powder burns before the bullet can start moving down the barrel (increasing the volume and mitigating the pressure rise) the pressure will get high enough to start breaking stuff.
The rifle design could be better. This is how they will all fail with an extremely overcharged round. The thinking shouldn't be "it'll never see rounds that hot." It should be, "If by some freak occurrence, the guns sees a round this hot, how can I arrange the failure points so that the shooter is least likely to get chunks of steel flying into his head and torso." No, I don't think Serbu bears any responsibility - the ammo was clearly well outside of any reasonably predicable envelope.

Dang KB new testing reminded me of this old video...
will just sweep up the powder on the floor and make some rounds and see what happens .. LOL ..

It’s actually a lighter projectile. The slap projectile is actually halve the weight of a standard ball round @ about 350 gr. This allows 4000 fps as opposed to the standard 660 gr. ball round @ 3000 fps

I see. I wouldn't buy ammo for a 50 bmg that was someone elses hand loads or some unknown manufacturer. I wouldn't for any caliber for this exact reason.He was using the equivalent of gun show ammo sold in used Ziploc baggies. Who do you blame?
In the video he says that last round that exploded and destroyed the Serbu was because he purposely shot an overcharged round to recreate the original incident. Though I’m not sure if the other 12 rounds that he shot were reloads. For me reloads are a little sketchy as it is, let alone in some .50 SLAP’s…no thanks.

Because those rounds cost so much money, somebody probably was reloading them and accidently filled it twice and never checked it. Thats my guess.

i haven't finished the video yet .. but how did he over charge it .. ??
in the original thread here of his accident .. i went out to my shop and took some photos of a 50cal factory load that i disassembled ..
and put the powder it had back in it .. its a full case full of powder ..
so what powder is smaller then factory ? cuzz that shit is really small balls .. what did KB use to over charge it ..

You could easily do it with something like tite group.

Here’s one,
Similar Labels, Disasterous Consequences
The shooter, Denny K., was assembling some rounds for his brand new 7mm-08 Savage hunting rifle. He thought he was loading with Hodgdon Varget. Instead he had filled his powder measure with Hodgdon TiteGroup, a fast-burning pistol powder. The labels are similar, so the mistake is understandable. But the results were devastating. Here’s what 41 grains of TiteGroup can do in a 7mm-08:

I guess a 230 grain load of TiteGroup in a .50 bmg round would be like 460 grains of H50BMG

yeah i can see loading it full case with a fast pistol powder .. is that what KB did ?

what would happen if you loaded a 50cal with FFFFg full case ??

Oh I have no clue but it sounded like you were alluding more to the size of the powder than the type to create overcharge. He could have done a ton of things though. Hell, maybe he filled the whole case with flash powder!

True, but the round he blew the second gun up with was clearly not a SLAP round. Projectile looked like turned brass to me but we don't get a great look.

My bad
Now I understand what you were saying about
A heavier projectile and faster powder or combo.
I fell in the “power of suggestion” trap and assumed it was another slap because he was shooting the last 12 of them.
Good observation brother! (Stop frame)
