        anon, the only reason cannons have the threads inside the breech is that it's easier and lighter to do it that way. There's more surface area around the outside of the breech and thus more threads, which means there's more threads holding the cap/breech block onto the gun.

        Other than you having a preconceived notion, why would more threads and more surface contact area between the two parts be weaker around the outside?

                That’s not true at all. Strength depends on how many threads and the depth of them. You could easily have more surface area on the outside. It might be too bulky but it can be stronger.

      Being threaded is not inherently weaker. It is only a question of how big and how many threads there are.

      The problem isn't that it exploded, its that it exploded TOWARD MATT. If the gun had been engineered to fail at the top instead of the back with a simple pressure venting hole he'd have been uninjured.

      It is possible to design a gun to fail more gracefully from an over-pressurized chamber. However, a conventionally designed gun with front locking lugs probably would have thrown the whole bolt back in his face and brained him in the process.

                A bullet going down the barrel is a bullet still in the barrel, sealing in the gases, despite it being an increasing volume. It's a bit different than a vent to atmosphere right in the place where pressurized gases would be an issue.

                >adding a hole a tenth of the diameter of the barrel is going to relieve enough pressure to prevent a catastrophic kaboom, when during the accident the breech blew off before the round had even exited the barrel
                No, what it's going to do is frag the breech, throw around some extra shrap, and still blow the back end off. Again, the case head hit the bolt so hard it peened in the head stamp. With a chunk of brass. On steel. The Barret, which has vent holes and an inherently weaker design, blew pieces of the bolt and trunnion at lethal velocity out the back and sides of the gun.
                Vent holes are designed to relieve an accidental double-charge, not a penta-charge with powder burning multiple times faster than the intended charge.

      Screws are perfectly fine for locking.
      If anything they supply excellent amounts of surface area.
      The US Army even has been seeking to use screw style breeches as a means of bearing super high pressure ammo.

      Sigh. Do you have any idea how the guns in pic related are locked?

      >If the gun had been engineered to fail at the top instead of the back with a simple pressure venting hole he'd have been uninjured.
      The bullet exploded with so much force that it sheared off the metal bits directly behind the breach. And based on how the threads of the breach cap sheared off, the internal pressure is estimated to be 160,000 psi which is more than 100,000 more than what the gun is rated for. There's only so much you can do at that point.

      https://i.imgur.com/bLhjSze.jpg

      Here's my gripe with the whole system: those ears only provide so much shear surface, and become projectiles once they're torn off. If Serbu simply doesn't cut the channel behind those ears, it's a massive cap deflector that prevents what happened to Matt. It saves on machining time, but adds some weight, and you'd need a hammer extension. It's a .50 cal so weight isn't a problem, and the cost savings on machining time offset the hammer extension.

      guns are built to 100% of the spec. they're not overbuilt. if they can handle a cartridge that is out of spec then they can be made lighter, and will be.

      ''The spec'' is what SAAMI or CIP consider to be maximum safe loadings of ammunition - but they are tested to a proof value of that, so well over that pressure.
      For example, CIP maximum means that the average of a tested lot of ammunition must be 100% of that maximum pressure (it may not be higher). However, an individual round may go up to 115% of that pressure, and the firearm is proof tested at 125% of that pressure.

        A hammer extension isn't really necessary since your thumb fits between the ears. There is no reason to machine out that area, Serbu is a hack.

                Make one section of the chamber much thinner so that an explosion is directed that way. Top, bottom, one of the sides, just anything but back toward the shooter. If it's weakened enough, it will also stop pressure from building so high. Basically weaken one part of the gun so it fails at anything 10% over spec and failures happen through that part AND they happen with less force. You get broken guns much more easily, but broken people much less easily.

                Sure, a Chinese car might not save you where a Volvo would. Yes, it's a worse design from a safety standpoint. Is it the design's fault? No.

                [...]
                So? If you have a point on the gun that always breaks at 90,000psi the gun simply cannot build up to 160,000psi as that part will blow out in fractions of a second.

                When other guns explode from Bubba's pissin hot handloads it just breaks the gun and maybe maims a hand. Most guns simply cannot fail in a way that seriously endangers the shooter's life.

                KB tested a Barret with the same pressure loading and it blew chunks of the bolt directly through the kill zone for a right-handed shooter. The problem wasn't the Serbu, it was effectively putting a slug of C4 in the chamber. This was not a "hot handload".

                The Serbu blew up from pistol powder, not C4. The Barrett blew up from actual literal C4. Even if the pressure is the same it is not generated in a similar way. Pressure from powder stops building if the gun ruptures elsewhere, C4 can generate a pressure wave even in open air.

                That would not be enough, unfortunately. The base of brass is extremely hard and thick from the forming process. The best place for a blowout to occur (read as the thinnest part of the brass) is close to where the bullet is crimped in place.

                Indeed, that is why vent/blow-out holes used to be a thing like in:

                https://i.imgur.com/1mPhutj.png

                A case rupture can simply be a fault of the brass. If the ruptured gasses were allowed to vent, LIKE IN ALMOST ANY OTHER RIFLE, the gun would NOT catastrophically explode.
                Most firearms not only do not explode when the case ruptures, they also have a way to direct the expanding gases away from the shooter safely. This Serbu design transitions into a fucking pipe bomb if the case ruptures.

                In the thread's topical case, and in response to the guy who suggested putting vent holes around the perimeter of the cap, I provided a counter that it would not be enough and would need to be located further up away from the base of the brass.

              By full speed you mean 45mph. Maybe 70mph. Well within the normal driving parameters. The round he shot would be like driving 150mph. How’s that collision going to go?

                Yes driving at 45mph is very normal. And every modernist vehicle can handle wrecks at that speed. They can’t at 150mph which is what this would be like.

                What’s your issue with that?

            In terms of things that might go wrong when driving, a bomb in your dashboard is catastrophic but fairly unlikely.
            Contrast with different ammo loads being used, that's more likely to occur so it's reasonable to take it into account at least somewhat when designing the firearm.

      The bullet exploded with so much force that it sheared off the metal bits directly behind the breach. And based on how the threads of the breach cap sheared off, the internal pressure is estimated to be 160,000 psi which is more than 100,000 more than what the gun is rated for. There's only so much you can do at that point.

            Hell, go 75% over spec. But it should be intentionally failing in a predictable manner WAY before over double the rated pressure. It's possible to build things too strong. A bomb is only a bomb if it lets pressure build. If it simply breaks the gun before dangerous pressures there's no risk to the shooter.

                A cartridge going off isn't a slow build up of pressure. It happens in less than a tenth of a second.

                So? If you have a point on the gun that always breaks at 90,000psi the gun simply cannot build up to 160,000psi as that part will blow out in fractions of a second.

                It is impossible to get 300% over max pressure using powder if your gun is designed to fail at 150%. The solution isn't to make the gun stronger but to make it MUCH weaker so it readily fails in a predictable and directed manner. Like an overpressure valve in a steam boiler.

                Taking apart the rounds would have shown him what spec the box he had was loaded to, not the actual specs. It probably would have given more warning that something was in fact up, especially if the powder was sweating nitro, actually a wad of C4, or otherwise looked fucky. But given that he repeatedly ignored overpressure signs on the gun before it failed, if it was just powder I suspect he would have just measured out the average load and tried to match it between the rounds before going back in there and blowing up his gun anyway.

                Anon the bullet going down the barrel is supposed to relieve pressure. The fact that it was able to build up to over 160,000 psi means the powder was burning way too quickly and the gun was going to blow up regardless of your vent holes being there or not.

                A bullet going down the barrel is a bullet still in the barrel, sealing in the gases, despite it being an increasing volume. It's a bit different than a vent to atmosphere right in the place where pressurized gases would be an issue.

                I think the point is that those legally obligated safety measures ARE the part where you say "you must design the car to withstand a crash to the best of your ability". Saying it's all the user's fault is like selling them a car from the 1940s where if you get in a crash you get turned into chunky marinara because the car hasn't been made with those kinds of considerations in mind because nobody gave a shit.

                It's not the gun design's fault. But it a +P+ round blows a gun, it should still fail in a safer mode.
                This shit happened so long ago and yet people are still talking past each other. Most aren't demanding Serbu to take the liability of a full retard round being loaded into his design, people are just saying that in hindsight the RN-50 doesn't have a fail-safe against this issue. No, a rifle should not be built to survive that overpressure event. It should at least be built for shit to blow forward or to the sides under the assumption that there's people behind the rifle and the firing line.

                .50BMG proof pressure is 65000PSI.
                Anything past that point is beyond what any cartridge should be loaded at.
                A gun like the Serbu would reasonably be expected however, to withstand say 90000PSI. That is ~x1.5 proof and gives you a significant safety factor in the case of degraded or otherwise dysfunctional ammuntion. That is very generous to the shooter even.

                Very few firearms are built to withstand anything like 100k PSI. The excess weight and expense makes it undesirable on both ends. And beyond that is very rare.

      Way too slow. I ran the numbers in Quickload and the only way you're getting the 300k PSI is through compressing some powders into a solid mass (120% fill or more) or filling at 100% capacity with ultra-fast powders meant for .32 ACP like Accurate #2. I want to say it's the latter mainly because it requires a lot of extra effort to be able to compress powder that hard.

        For fucks sake this isn’t any different than people firing over pressured .40 reloads through glocks and mangling hands. I love to joke about glocks being grenades but the design isn’t inherently unsafe

            A simple “no” would have sufficed. You actually can calculate when the threads would fail based on thread depth, number of threads, and the material. Although I’ll admit I can’t do that calc.

            You clearly didn’t watch the Barrett exploding. Or the video where he blew up another Serbu that took a 190k psi round to do it. Why are you ignoring the other failures that are similar? In the process of blowing up the serbu he had to use vice grips to get the cap off and get the round out. Why are you acting like that’s not insanely overpressured?

                That the 380 MPa of chamber pressure of a .50 BMG acted on the cap inner surface area of ~1200 mm^2 (approx 40mm diameter disk) due to a case rupture creating 456 000 N or 45 600 kgf of force which the threads couldn't handle because it was only designed to reliably withstand the proof load of 450 MPa over the ~250 mm^2 surface area of the .50 BMG case which offers a mere 112 500 N or 11 250 kgf of force, which is FOUR TIMES less than if a case were to rupture at maximum chamber pressure.

                With this dogshit Serbu design a case rupture of an ordinary 380 MPa pressure .50 BMG cartridge creates FOUR TIMES the bolt thrust of a .50 BMG proof test load.

                In the original video it is claimed that 85K PSI or 586 MPa is the maximum those threads can handle with the .50 BMG surface area this comes out to 586 MPa * 250 mm^2 = 146 000 N or 14 600 kgf. If not for the closed cavity behind the cartridge this would easily be strong enough but as it stands a totally normal cartridge that ruptures could cause 456 000 N or THREE times the force at which the gun designer says that the breech will blow.

                Therefore a case rupture even at a pressure three times less than maximum chamber pressure would be sufficient to blow the cap.

                I'm not too good at physics, but I think it's because of the larger area that the pressure can exert force on.
                With an intact case, the case head pushes against the bolt.
                Ruptured cases vent gas into the chamber and thus the pressure pushes on the whole area of the bolt face.

                A video about a gun blowing up from an overpressure round is not evidence. Nobody is saying that that is anything special. You put 190K PSI in a gun and it WILL blow up, that is not proof, and that is nothing new.

          In those videos you can see the case still in the chamber, which blew out in an even ring at the head. That's consistent with an absolutely insane overpressure. It's partially welded into the chamber, and the case head hit the bolt with so much force it left a layer of brass welded to the surface, and PEENED THE FUCKING HEADSTAMP ONTO THE BOLT FACE. That is not a sign of a case rupture. That is a sign of someone packing several ounces of pistol powder or a nitroglycerine charge into the case.

            That roughly tries to replicate a blackpowder cartridge. 28000PSI is the SAAMI spec, but even a company as ballsy as BuffaloBore will tell you that running below that is safer.
            You can also get modern loads of .45-70 that run 400-440 gr at 2000FPS or higher.

          That's because most firearm actions are designed to not fucking explode when the case ruptures.

        What happened there was not a case rupture.
        It was an extremely overpressure round.
        Those are entirely different issues.

        If the gun was damaged by a case rupture and say gas jet cutting in the breech, that'd be one thing to criticize it for. But that was not the issue. The issue was that it had a loading that was deliberately spiked tier. Potentially compounded by the muzzle brake on the end interfering with the release of the SLAP sabot increasing pressure within the breech even more.

          The chamber pressure curve experiences max pressure just after the bullet has left the case, therefore a muzzle device, or even a plugged muzzle will have no effect on the breech end of the gun. Wherein is it proven that it was not just a case rupture when you can clearly see that a case rupture would be sufficient to blow up the gun due to the breech cap design?

          • 4 weeks ago
            Anonymous

            Obstructions in the bore still cause blowouts because they put sustained stress on the action and cause that pressure spike to become sustained.
            This is how even a revolver can see its breech and chamber explode if there's a squib in the barrel.

            You do not see that a case rupture would be sufficient to do the damage seen in the slightest.
            If there was gas jet cutting visible, you could make that argument, but that would instead damage the breech and chamber area. It would not blow out the entire locking thread and send the cap back at the shooter.
            Case ruptures put hot gas where its not meant to be and let it scour metal and jet back into the shooter's face. They don't explode the entire gun.

            Here's a good example. Where you can see why a case rupture is bad, the hot gas flying in dangerous directions. Not that it explodes the firearm apart. And this is in a gun that isn't otherwise designed to deal with case ruptures.

            Or another example

            With an AR, where the case blew out, ostensibly sending hot gas at the shooter, but the gun stayed perfectly functional afterwards.
            A case rupture could have damaged the extractor due to jet cutting. But otherwise it won't turn a gun into a pipe bomb.

              How would the case rupture jet back into the shooters face etc. in this design when it is completely contained inside the threaded cap? Therein lies the very problem, the pressure cannot vent out, not even into the shooters face, and therefore creates a much more dangerous pipe bomb effect.

              • 4 weeks ago
                Anonymous

                It doesn't matter.
                A case rupture doesn't create more pressure inside the action than a standard detonation will. It literally can't do so significantly because its the same charge being detonated.
                What is dangerous about case ruptures is the risk of the hot gas cutting into things. Not the pressure. Hot gas can get underneath extractors and shear them off. Can leave slices in the breech.
                The failure of the Serbu was not a locking lug being sheared off from gas cutting. It was the entire breech being ripped off by extreme overpressure in the detonation. If we saw 'slices' in the cap or the chamber area, that'd be indicative of the former. That we instead saw the entire breech cap shot backwards hundreds of feet per second is indicative of the latter.

          Volume not area, but the gist of it is correct.

          The volume behind the case inside the cap is equivalent to a single inch of barrel. And we know that it takes multiple inches of bullet travel until peak chamber pressure has passed.

            We have him boys. This dipshit can't tell you what pressure is required to rupture the case in that area because if he answered that then one of the following would have to be true:
            1)the RN50 would fail with every shot, which would be weird because there are hundreds of unexploded RN50s running around
            2) the round was overpressure, which is what everyone else is saying so he doesn't get to be a specially retarded little boy on his own.
            >when does max pressure actually occur?
            Luckily I'm not a brainless ballistlet like you, the pressure doesn't peak for over a millisecond after ignition in .50BMG and the bullet is well away from the case.
            Now what happens to peak pressure when we add a huge void like your theory dictates? (Effectively change seating depth to simulate)
            A change in seating depth by one inch (what you said the equivalent volume of barrel is) drops the pressure from 49000PSI (235 grains of 24n41 under a 750 grain Amax)
            To 32000 PSI at 1.73 milliseconds. And would lead to obvious gas venting in the shooters face.
            Your theory is garbage. It's totally unworkable and describes not a single behavior of the real life system.
            The round was overcharged. Probably some Bubba boomer who thought 250 grains of H110 would really put the wallop on those SLAP rounds.

            A single inch of barrel causes a dramatic drop in pressure. You are wrong

              Anonymous

              Seating depth is simply not the same thing because the cases fracture only after high pressures are already reached. A more fitting comparison is a bullet that is traveling inside the barrel. As you can see from this graph, the bullet travels a long distance at very high pressure, certainly way more than an inch, therefore a very high pressure is certainly attainable even if an expansion volume corresponding to one inch of barrel length were suddenly added by the fracturing case.

            Yes indeed in that video the brass case held and did not pressurize the cavity. Besides, due to how pressure curves work on guns if the breech can handle the start of firing it can usually handle a plugged barrel in which case it is the barrel that blows. This is because the highest pressures are at the start.

          Case ruptures happen to unsupported areas of the brass like the extractor cut. There is no such place in the Serbu design. The brass is entirely supported and has no way to rupture until the action itself fails.

            With rimless cartridges like the .50 cal the rim area is always exposed, there is no need to cut away a part of the chamber like there is with rimmed rounds. Go look into the chamber of your AR, yo you see an extractor cut?

                Indeed, a case rupture goes hand in hand with overpressure rounds. And yet with an AR your life will probably not be at risk even if a case were to rupture, and that is because the gun was designed by someone at least passingly intelligent.

                Once again though.
                A case can only rupture if it is unsupported somewhere. Otherwise the chamber and bolt face provide support and keep it intact.
                With the Serbu design the case is 100% supported. There is no place for the brass to flow and no way for a case to rupture UNTIL AFTER the action has already failed.

                That is simply not true. The rimmed section of the round is sticking out of the chamber like in any other chamber design. This section is not supported radially. The chamber cap is a flat wall.

                You'd think that with how badly designed and unsafe the gun is that we'd have dozens of other reports of people experiencing similar failures and probably even a few resulting deaths. Weird that there haven't been any of those besides the one.

                Modern rounds tend to not rupture because of high production quality. Simple as that. That is also the reason why such a safety feature was overlooked.

                I actual did the math in one of the original threads and the additional volume revealed by the proposed venting also reduces the pressure below the reasonable threshold for thread failure on the cap.

                That's incorrect though, the volume is tiny.

                But lots of .50 BMG that's available is military surplus, and the RN-50 manual even states that the gun should be able to handle it. If you're arguing that it can't, and that the reason these guns don't explode more often is because of modern ammo, we should still be seeing multiple reports of RN-50s exploding everywhere from people shooting surplus ammo through it, and we're not. So which is it?

                Either people are only shooting modern ammo through them, which isn't likely, or surplus ammo is, the overwhelming majority of the time, just fine to shoot and events like the one that happened to KB are so incredibly rare and unheard of that no one would have expected the gun to fail like it did.

                No modern or surplus ammo is going to be loaded as hot as the one that KB used, that’s why this kind of thing has never been reported since with this particular gun. He had to have a round INTENTIONALLY loaded super hot to get the same result. If you buy non-factory or hand loaded ammo that you yourself did not load, you are taking a risk. You have no right to complain or blame the gun when something goes wrong and you get seriously injured because of it.

                You actually have no idea what you are talking about. Your theory is not internally consistent and cannot be correct. Either there is volume for the case to move into and rupture, or there is no volume for the case wall to move into and it is supported.

                The unsupported case area is 6mm in length, this means a 6mm thick wide disk with not a lot of volume for gas to expand into, equivalent to and inch or so of .50 cal barrel length. Do you think the pressure drops significantly in the chamber after the bullet has traveled an inch? (hint: it does not)

                We have him boys. This dipshit can't tell you what pressure is required to rupture the case in that area because if he answered that then one of the following would have to be true:
                1)the RN50 would fail with every shot, which would be weird because there are hundreds of unexploded RN50s running around
                2) the round was overpressure, which is what everyone else is saying so he doesn't get to be a specially retarded little boy on his own.
                >when does max pressure actually occur?
                Luckily I'm not a brainless ballistlet like you, the pressure doesn't peak for over a millisecond after ignition in .50BMG and the bullet is well away from the case.
                Now what happens to peak pressure when we add a huge void like your theory dictates? (Effectively change seating depth to simulate)
                A change in seating depth by one inch (what you said the equivalent volume of barrel is) drops the pressure from 49000PSI (235 grains of 24n41 under a 750 grain Amax)
                To 32000 PSI at 1.73 milliseconds. And would lead to obvious gas venting in the shooters face.
                Your theory is garbage. It's totally unworkable and describes not a single behavior of the real life system.
                The round was overcharged. Probably some Bubba boomer who thought 250 grains of H110 would really put the wallop on those SLAP rounds.

                It's not a change in seating depth since rupture happens AFTER big bad pressure happens. A case rupture can happen for a large number of reasons, one of them being some degree of over pressure. Were the gun designed properly these ruptures wouldn't automatically be a lethat threat.

                https://i.imgur.com/7xjHsBz.jpg

                That the 380 MPa of chamber pressure of a .50 BMG acted on the cap inner surface area of ~1200 mm^2 (approx 40mm diameter disk) due to a case rupture creating 456 000 N or 45 600 kgf of force which the threads couldn't handle because it was only designed to reliably withstand the proof load of 450 MPa over the ~250 mm^2 surface area of the .50 BMG case which offers a mere 112 500 N or 11 250 kgf of force, which is FOUR TIMES less than if a case were to rupture at maximum chamber pressure.

                With this dogshit Serbu design a case rupture of an ordinary 380 MPa pressure .50 BMG cartridge creates FOUR TIMES the bolt thrust of a .50 BMG proof test load.

          Case ruptures were a larger issue in the form of shitty brass not having enough ductility to expand and contract without splitting.
          That is why a Mauser has a vent hole. To make up for poor material science in case manufacturing.
          It is not designed to handle vastly overpressure ammo. That was not the intent or aim. That will not save you if you drop a spiked >100k PSI cartridge into a Kar98k and pull the trigger. The bolt lugs will shear off and you will get a bolt in the eye socket.

    BTW properly engineered designs of any kind should fail gracefully AKA graceful degradation AKA fault tolerance.

    I'll use a hot rodding example since many k-tards have cars and trucks. In ancient times cast iron flywheels could explode at high RPMs. Early countermeasures still in use include steel flywheels far less likely to fail but still quite capable of cutting off driver feet and leg bits when they let go.

    The eventual solution is the steel scatter shield. It anticipates failure by being designed and tested to contain flywheel explosions. Transmission blankets are similarly used to contain exploding gearboxes.

    Why scatter shields and trans blankets are needed in competition etc:

    Proper escalator design's failure mode is to become steps vs. bug design where they devour passengers. Automatically feathering propellers reduce drag on engine failure instead of becoming surprise control surfaces.

    Why do non-technical people have opinions on shit they do not understand?

    "Me like boomy thing. It no matter how boomy thing fail if over-pressured because duh shiny" reflects zero understanding of quality design.

    I don't really understand the purpose of buying a "budget" .50bmg rifle. Shooting rifles in that caliber is kind of a rich man's game, if you can't afford a few thousand dollars for a good rifle you probably aren't prepared to buy all of the expensive ammo and/or reloading components. A lot of ranges won't even let you shoot it, you might need to either have a lot of property, know someone who does or look around for a range or public land where it's okay to use it.

    Even this piece of shit pipe gun is sold for $1600. For just a little over $2000 you can get a gun with an actual action. For about $3000 you can go full retard and get a Barret. So this Bubba home depot shit seems really goofy.

      You’re off by about a $1000. A single shot Barrett is closer to $4k and other single shots are $3k. The appeal of Serbu is you can get the rifle and a good scope for the price of just a rifle. Or buy 600-1000 or so rounds for that $2-3k you saved which is a lifetime supply of .50 BMG. You can argue if that’s the “right” choice or not but there’s an appeal.

    Tbh though a rifle chambered in something as big as a 50BMG, that has the potential to kill you in the event of a catastrophic malfunction, should probably be rated to withstand the highest theoretical chamber pressure possible, so that the thing never blows up, no matter what.

      The Serbu will do that just fine, a .50 BMG loaded even way above spec will not blow it up, that is AS LONG AS the cartridge does not rupture.

      >No idea where the case could have ruptured,
      So you have no evidence of a case rupture

      And you have no evidence of overpressure.

        Yes we do, you’re just refusing to acknowledge it.

          A video about a gun blowing up from an overpressure round is not evidence. Nobody is saying that that is anything special. You put 190K PSI in a gun and it WILL blow up, that is not proof, and that is nothing new.

            Go buy a Serbu, buy some .50 BMG brass, weaken them in a way that makes them more susceptible to case rupture, load them to factory standards, and test them to see what happens.

            We already have a video showing what happens when an overpressure round goes off in a Serbu, and it’s nearly a 1/1 match of what happened in the original video. If a case rupture from a standard round produces similar results, then you have a leg to stand on. Right now, you don’t.

            So recreating the event doesn’t mean anything? Cool. Got it.

            For like the 3rd time, why do you think it’s a case rupture? Just answer that. How is it any more likely than an overpressured round?

              An overpressure round of this pressure would require a completely different powder rhan the other SLAP round which functioned just fine. Therefore I think that the case just happened to be weak and rupture for some reason instead of the loader switching up the powder part way through a batch.

                The other rounds didn't function "just fine". There are no signs of a weak point rupture in the actual case, which you can look at yourself. The exact same batch of ammo blew up two other guns in testing, with no signs of rupturing at weak points -- they all blew through the strongest part of the cartridge, with immense force.
                Watch the actual videos before shooting off your ignorant fuckpipe.

    There's no need to sell other gun designers on the idea since everyone else is already doing it.

      A 5.56 overpressure detonation is also going to be vastly smaller and less powerful than a .50 BMG overpressure.

    >mogs your serbu poverty-50

    Doesn't .50 bmg have a reputation for case rupturing if only because M2 headspacing is a bitch. Most guns aren't made with fail-safe in mind the serbu problem is just a happenstance consequence of making a .50 bmg rifle as cheaply as you can resulting in no steel around the tube pipe action to catch a failure. also there's probably a reason that every other screw-breech gun breech plug has external threads the internally threaded cap design fitting around the entire breech end probably puts more torque or whatever on it due to the added distance. The threads are also relatively shallow even considering scale artillery screw breaches are so thick they're basically a series of locking lugs. None of this is enough to be an inherently unsafe design just not optimal and another result of cost cutting. It's an in spec design but equivalent of shooting a pot metal surplus revolver it probably won't blow up but there's less margin for safety especially if you put weird ammo in it.

    >gun should be built to fail in a safer way
    This argument is retarded when you consider the level of safety this gun was built to and what caused it to fail.

    The round used to blow it up was so overpressure, it almost seems malicious in its construction. With anything but the fastest burning powders on the market, you have to fill the entire case to the brim, use a rod to pack that powder in, then pour more powder into the empty space before seating the bullet. It seems intentional, like the spiked ammo from Vietnam.

    Under nearly any other condition, the rifle could eat a Barrett-killing load as if it was normal pressure. This is including the less dumb but still retarded idea of filling it 100% with a fast burning rifle powder like H4198 or possibly even H110. The design is physically incapable of blowing up like how it did unless someone was trying to fucking kill you with the ammo like whoever sold KB those SLAP rounds.

      Wasn't the story with the rounds that it was stored improperly for a very long period of time? Like, 20 year old ammo that wasn't sealed or in stable conditions? Sometimes that can cause overpressure. But to that extent? I don't know.

        Most improperly stored ammo loses volatility; especially .50 BMG which uses fuckhuge grains of powder that take way longer to degrade.

          Yeah, but I understand particular kinds of powder can make them more volatile sometimes. The quickest example I can think of is Turkish 8mm mauser ammo. Forgotten weapons did a video on it showing that the old turkish 8mm destroys guns and it's worth the extra money to buy something else and not destroy your machine gun or hurt yourself.

      The problem is that it is too strong. Pressure cookers blow at 3bar so they don't ever reach 30bar before exploding. Stronger isn't safer. The fact it can eat Barrett killing loads isn't a good thing its a fucking problem.

        >Pressure cookers blow at 3bar so they don't ever reach 30bar before exploding.
        Because pressure cookers are capable of reaching that in a wide variety of natural situations where the RN-50 has exactly one way of getting there that would require failure at several points on the shooter's part.
        >The fact it can eat Barrett killing loads isn't a good thing its a fucking problem.
        Only if you're being stupid. Barrett eats a bad round and you're out $10k with possible injuries. RN-50 eats a bad round and you have a lot of trouble extracting it while hopefully saying "maybe there's something wrong with this stuff I should stop".

          You must have watched a different video?

            Yeah, I ALSO watched the follow-up where he had to hammer out every single one of the remaining rounds on extraction. I bet he had the same trouble when he was shooting the first video and omitted that because he didn't want to seem retarded. It's either that or the first few he shot were completely fine and he somehow managed to ONLY shoot the properly made ones first.

              I think even in the original video he acknowledges that the recoil and sound and muzzle blast is weird and inconsistent between rounds. The first two might have just been notably hot and then the killer happened to be pressure spiked to the moon. I don't know how the difference would be that big if they were from the same batch.

      Instead of it being intentional, how about it was just a case rupture that explodes the gun because of the garbage design?

    In the follow up video where Scott shoots the remaining ammo, he has to pry and hammer every spent casing from the chamber.
    I bet this happened with every round before the accident too and he should just have stopped shooting these SLAP rounds due to obvious inconsistencies.
    Never shoot mystery meat ammo should be common sense.

    gun company engeneers a cheap 50 bmg to shoot for fun and testing, capable of shooting ammo far above normal preassures but barely any safety features because nobody would be retarded enough to make a 50 bmg loaded to infinity or a 50 bmg squib

    >guy buys specific 50 bmg cartrige that has fake replicas of it made by Bubba " the pissin hot loads" Fuddberg.

    >The sketchy load was loaded over safe preassures, into infinity and beyond.

    > gun pipebombs, shears off any and all metal in its path and nearly kills the shooter

    >internet declares it a gun fault.

    No it is the retard making the cartrige that is at fault

    How would you build a 50 bmg safety mechanism,

    anything you add potentionally adds more shrapnel with that cartrige depending on the retard loading the 50 bmg. Unless you have 15 pounds of metal shit bolted to the back. And the front with an aramid layer around it to catch any shattering pieces of the gun
    Ventholes would have reduced the force,

    in kentuckys case it wouldnt have made much difference , that metal cap busted through the metal ears, shattered his safety glasses and broke his face in multiple places as well as sent the ears flying into his neck and down to his chest.

    For 556, 308, 30 06 it is easy. Their maximum force is fairly limited compared to a fiddy.

    Even semiautomatics are not fullproof against complete and utter human retardation:
    ian "forgotten weapon" mcollum took some 556 casing shrapnel to the chest when his gun blew up because the reloaders did not clean the pistol powder out of the machinery. For a fiddy it would have been even worse

      Straight blowback. Locking actions, by definition, completely resist the movement based on the mechanical strength of components. Mechanical strength can fail, but mass does not fail. Ever heard of an Oerlikon 20mm blow up? Neither have I.
