With Scott, it was most certainly not a rifle problem. There is potentially a lot of very dangerous surplus ammo out there from the many countries that have left booby-trap ammo behind in war zones over the course of our violent world history.
Many years ago, when AKs were still legal in Canada, I screwed up the measurement of a new powder when reloading some .223 rounds for my Norinco AK. I had no reloading data for that powder, so I took an educated guess based on similar powders, then cut it back a bit so that I could "dial-in" optimum velocity. First-round didn't sound quite right, and it jammed. Dropped the mag, slammed the bolt open, and lost the spent case. Tried again, and it did a double shot and jammed. Several of the AK's rivets were now loose and the receiver bulged. Being more careful, I hammered the bolt open and caught the case. Half the back blew off, my rounds had detonated. From my first view of Scott's accident, I have wondered if it might not have been a detonation, and seeing the abuse Edwin's done to your poor rifle with the breach staying intact kind of re-enforces that...

As I said in the previous KB video, this is likely caused by 1 of 4 things 1. Round was cleaned up in a vibratory tumbler, removing the layer of retardant on the grains of the powder causing a detonation 2. Round was undercharged, an undercharge can cause a secondary detonation effect AFTER the bullet leaves the muzzle, if the primary peak was 45k psi the secondary peak can hit upwards of 80k psi, and this is with a light charge or a charge of powder too slow for the bullet. 3. Improper ignition, commonly associated with magnum pistol powder, particularly h110, the charge can ignite, burning off the retardant layer creating what's referred to as "the green glob of death", when this melted partially burned charge re-ignites it burns MUCH faster than it should for the powder type leading to rapid self disassembly 4. Improper powder, if an incorrect powder was used, pressures can reach absolutely silly numbers, like a case full of IMR-4064 in a 50 bmg would cause rapid self disassembly.
The name calling by the idiots. The people the knew were against it. People like me didn't think it was the firearm but have been waiting to make sure. Then there are the people that wanted to get big off Scott's misfortune
@@dstglizzytwotonez4298 because it can fire any 50 cal. Slap round shots the same pressure as they are the same powder load. If I designed a track for mopeds do you think it would suit superbikes the same? I mean they both have two wheels and a motor so they are the same right? The slap round had well over 2-3 times the pressure that a .50 is supposed to have period. How about you build a failsafe in your phone to keep it from responding stupidly.
@@Deere2154D Understand he's not wrong. Nobody expects their gun to blow up. But when it does the pressure follows the path of least resistance. If you research how a Barrett blows up, nothing is able to come back towards the shooter. Hell there are videos on RUclips of it happening. Lot's of guns are designed that way. The RN50 is not designed that way.
@@dstglizzytwotonez4298 no modern bolt action rifle or single shot designs has fail safe points, if the lugs fail the bolt is going straight into the user's head
It was 100% confirmed as the SLAP round that did it. They were designed for the Browning M2 Machine gun- But the rounds would also cause the M2 to explode as well, so that's actually not an uncommon issue with those rounds.
There's just not enough mass between the shooter and the breech. You basically have some threads between you and the ignition of a .50bmg cartridge. I'm sure that 99% of the time you'd be fine but I wouldn't chance it.
That’s already been confirmed dozens of times. This shouldn’t even be a question anymore. I should probably buy one of these while all the idiots are afraid of theirs and willing to sell it dirt cheap to get rid of it.
Per other comment I just left, undercharges or improperly handled powder create higher pressures than an overcharge, if this was loaded with any sort of appropriate powder, it would be nearly impossible to fit enough powder into the case to cause the malfunction KB experienced. Now, throw an old surplus round in a vibratory tumbler for a few hours and let that h50bmg powder achieve a burn rate similar to tite group and the equation changes.
Let's start showing how good Serbu firearms are. If that barrel was even partially plugged with concrete and it blew that and a half barrel of concrete away, I'd say that was a well made rife. Destroy a Barrett next time. They need the advertising.
@@DaHoodedBandit No it's called a slap round spiking nearly 3x what standard pressure should be. It wasn't the rifle imo, it was definitely the ammo. That said, I would venture to say it did prove to be a safety design flaw- that is, *if* a detonation happens, the cap and ears that lock the breach have nowhere to go other then towards the shooter. That said, I think the rifle is a "good design" (I'm fairly sure it was designed by Royal Nonesuch working with Serbu), but needs a safety improvement just in the case of a detonation.
@@APGT90 That rifle is a glorified pipe cannon at best, so I wouldnt go around calling it "a good design". Also, if you knew anything about thermodynamics youd know that pressure ALWAYS takes the path of least resistance. Slap rounds are jacketed in a polymer case thats designed to fail WELL below what the failure point of the barrel should fail at. If you were right and it was a pressure spike, the polymer sabot around the SLAP round would have been destroyed and the pressure would have vented out the front. If that round was filled with anything short of c4 it would have vented the pressure out the front.
@@DaHoodedBandit Right, that's why there's videos of all types of rifles of all brands blowing up bc of bad ammo. Because all gun manufacturers are clueless to "thermodynamics". By the way, you probably meant physics, but I digress. Wrong gun powder = big boom, the end
Whenever you look for the spent round I always say to myself. Imagine someone came up with a device that you hover above the ground and beeps or vibrates even, when above metal. Someone could make a ton of money making something like that. Great video! Haha
Well moste of the so called metal detektors would be quit hard to use on a range, way to many signals there, but mabey a pinpointer could help them in some smaller Áreas.
I applaud and appreciate the protectiveness of Edwin during this video knowing what has happened, even if it won't happen again, he's not going to put anyone in danger just in case.
Scott used a bad round. I've ran 1000s of rounds thru my g19 but when I ran some reloads I bought from a friend of a friend of a friend my shit blew up too. Luckily I wasn't hurt
This is a testiment to Marks engineering skills, I would have never thought the Breech would hold up to the 50 cal being stuck in the concrete, I'm blown away y the strength of Marks guns, makes you wonder what was in Scotts slap round for it to catastrophically blow up the rifle! 🤔😳
Militaries hot loading speciality rounds...for specific weapons and enemies.....then if surplus and not used, they sit for ages and end up as retro ammo on online exchanges....I would vet it would ve hard to recreate the rounds load quality ,quantity and shelf time temperature changes....if one could though and control the round with the serbu killer load accurate and precisely every time...in a beefed up chamber/weapon....f-ing a that round and weapon system combo would take the spot as "America's armored enemy killer" all day every which way...
@@Jexorz86 No shit, I thought this had been cleared up months ago. There's still people out there arguing that it was a weapon failure after all the evidence? How do they remember to breathe?
@@danmackintosh6325 no because Mark hasn't fully said it wasn't the rifle. Most people know a obstructed barrel will explode the barrel. But it needs to be shown that the barrel is a weaker link and something went wrong before hand
@@Deere2154D I think this video shows pretty well what part of the RN50 is the weaker link. Definitely would be interesting to rebarrel it and continue abusing it with obstructions though.
@@danmackintosh6325 iunno. it might even make sense if it was just that one round that was off. but he had multiple problems before it happened, so maybe in that respect the gun could have been a contributor after it was already damaged from one of th previous shots... but either way, still 100% the ammo's fault
Can anyone else imagine having the connections to just blow up your .50 cal to make a point? Buddy, you’ve got either an awesome liquid income or AMAZING friends.
Bingooooo,that's right,the concrete was not cured completelly,it require at least 28 days on 20°C avg,but total curing time of the concrete is actually around 50+ years...
doesn't really matter in this case. it was still a significant barrel obstruction. Now we need a test similar to this with a round loaded with fast burning pistol powder.
Not arguing about the time/strength thing, but my (late) brother was a civil engineer and told me concrete columns 50 years old indoors in malls being torn down were still damp in their middles. Apparently all the water does not get used.
I knew from day 1 that the RN50 from Mark was not the problem. It was obvious it was an ammo problem they just kept getting hotter and hotter each shot. This proves something I already knew mark makes great firearms and I'd trust them I never stopped. Just make sure you use good new ammo in your gun unless you made the Ammo and you know what your doing. All gun have the potential to blow up and they do at times it is rare but can and does happen. So every make sure you keep your guns in good working order inspect every gun you get if you don't know what your looking at take it to a professional gun smith and always use ammo you know is good and what it's supposes to be.
WOW! This raises some serious questions about the equipment Scott was using at the time of his accident.... The power in those slap rounds must have been off the chart if a completely blocked barrel cant even remove the breach cap as happened with Scott's rifle....
That seems to be the most likely theory considering the pressures needed to strip those threads off the cap. It boggles my mind the amount of crap people are spouting about what they think happened.
@@omnomshibob The most likely theory is that the round was a little hot, and the heat treat on Scott's rifle was bad. It held up to regular use, but the ears and threading were too brittle for that hot slap round. The rifle was probably the problem, and that round was the catalyst.
😂 😂 😂 I wouldn't send it back either man 😂😂😂 (especially with a friend like Mark). This is a "Favorite Collection" piece right next to some of the rounds and stuff 👍🏻

Watching this video erases any doubt that i had in my RN50 breech as i have the same model as Scott did with the heavy barrel. Also a very fun rifle to shoot!
Impressive test, goes to show you how well built that gun is, and definitely makes you wonder about the ammunition (slap rounds) that Scott over at Kentucky Ballistics was shooting that day! That’s gonna make for a cool wall hanger. Thanks for the science
Respect to the manufacture of the RN50. He obviously wants to show that his gun isn't a death trap. Good test, any gun could be expected to blow up under similar circumstances. Avoid SLAP rounds but most 50 cals will be good.
I love y’all’s channel, but plz don’t do this to Justin’s .50 BMG bushmaster, at least I think that’s what his is. Or maybe a party popper in a buried .50 like this video but maybe mr. serbu will help with that, here is hope for you guys
After Scott's accident I hope NO ONE ever fires another SLAP round again. Yes, it was a good round for its time. It still is, for sure. Yes, it is a high performance round. Yes, it's very rare and very cool. But given Scott's accident, I don't ever want to see anyone fire one of those again. RN50 or Barret or whatever .50 BMG rifle, no one should be shooting those rounds. Let's just stick to the typical red, black, and silver tips. They are entertaining enough. No content creator needs to risk their life with some SLAP rounds.
Scott blew up another one just a couple of days ago it blew up just like the first one! The explosion and destruction was identical! It was Awesome! Scott at Kentucky Ballistics knows how it's done!
This an excellent example of how tough Serabu firearms are, takes a misload similar to handgrenade to blow the breach nut loose. Awesome video and even more awesome gun, I'll definitely keep using mine..!
@@joeklasen2845 I agree. I’ve poured Reinforced slabs and had heavy equipment drive over it within a few days without damaging it. It all depends on type, psi, thickness etc to determine cure times. But his column was so green that it at one point crumbled when he picked up a piece.
You proved to me that the RN50 is one tough rifle. The RN50 rifle held up much better than I thought it would. I think you have definitely proved that the RN50 can handle any type of hot or cold 50 caliber round. The action and cap are very strong. However, you have just proved to me that the KB explosion was totaling due to a 50 BMG Caliber Case Head Separation Failure. That is a big fat total case head separation, not a little smile on one side. This is a common failure from bad brass created by reloading too many times with head spacing for autoloading. KB’s round could have easily been a round reloaded one too many times with adequate headspace for autoloading. My concern is the RN50 screw-on cap style action is not strong enough to handle a round with total case head separation. When total case separation occurs the gas leaks past the cartridge base and leaks out around and back of the chamber and bolt causing varying amounts of damage. In the case of the RN50, the gases leak into the area inside the cap and are sealed in. These sealed-in gas pressures can easily create backward forces on the cap that exceed the stated design limits of the threads holding the cap on.
I believe Scott used a loaded SLAP round that was very hot, and the standard barrel on the RN-50 isn't designed for it. Thats why he upgraded to the heavy barrel designed for the full auto 50bmg. But, it could happen to any rifle. I for one love my RN-50, I have always wanted a 50bmg, but the Barrett was a bit out of my price range. When I found Serbu, I immediately ordered one. The couple months wait was definitely worth it, plus I had watch 50calval on here when she was posting. Lastly, always check your firearms before using. Never know what could have gotten in the barrel and checking them before firing is good insurance, oh I'd keep that one too, a new rifle should be sent for future research 😉
So about that theory of the sabot getting stuck in the muzzle brake blowing up the breech....😂 Great "science" as usual, Edwin!
Now you should ask IV8888 load up a slap round with indoor range floor trash pistol powder (like they did with the mosin test) then shoot it out of the same rifle. That might blow up the breech

If I designed a track for mopeds do you think it would suit superbikes the same? I mean they both have two wheels and a motor so they are the same right? The slap round had well over 2-3 times the pressure that a .50 is supposed to have period. How about you build a failsafe in your phone to keep it from responding stupidly.
@@Deere2154D Understand he's not wrong. Nobody expects their gun to blow up. But when it does the pressure follows the path of least resistance. If you research how a Barrett blows up, nothing is able to come back towards the shooter. Hell there are videos on RUclips of it happening. Lot's of guns are designed that way. The RN50 is not designed that way.
@@Deere2154D slap rounds run at the same pressures that regular .50 ball ammo runs at; right around 55k psi.
@@dstglizzytwotonez4298 no modern bolt action rifle or single shot designs has fail safe points, if the lugs fail the bolt is going straight into the user's head
You guys make me lol thanks for that you cheer folks up:) Please Be careful guys God Bless:)
If you still have the barrel, I'd like to see some different rounds fired from that split barrel!
I was going to say the same thing.
Yes we want the sience of a split barrel fiering!
@@robsmith4651 i would consider that as a single shell shotgun of slug ammo.
@@simonbach3618 You're describing a musket with missing material. It would just be an inaccurate, slow shot.
@@Nathan-dt2tu yes but they Are a science Channel so i want Them to show me lol
This makes me feel like it was definitely the SLAP rounds Scott had . That’s a pretty tough rifle.
Yeah, Scott himself even said in a video it was more than likely an extremely hot SLAP round that caused the gun to explode on him.
It was 100% confirmed as the SLAP round that did it. They were designed for the Browning M2 Machine gun- But the rounds would also cause the M2 to explode as well, so that's actually not an uncommon issue with those rounds.
There's just not enough mass between the shooter and the breech. You basically have some threads between you and the ignition of a .50bmg cartridge. I'm sure that 99% of the time you'd be fine but I wouldn't chance it.
That’s already been confirmed dozens of times. This shouldn’t even be a question anymore. I should probably buy one of these while all the idiots are afraid of theirs and willing to sell it dirt cheap to get rid of it.
Per other comment I just left, undercharges or improperly handled powder create higher pressures than an overcharge, if this was loaded with any sort of appropriate powder, it would be nearly impossible to fit enough powder into the case to cause the malfunction KB experienced.
Now, throw an old surplus round in a vibratory tumbler for a few hours and let that h50bmg powder achieve a burn rate similar to tite group and the equation changes.
Let's start showing how good Serbu firearms are. If that barrel was even partially plugged with concrete and it blew that and a half barrel of concrete away, I'd say that was a well made rife. Destroy a Barrett next time. They need the advertising.
Plenty of beef in the breech cap. Good engineering.
its called poor quality control, some are tight as can be and others..... well look at Scott
@@DaHoodedBandit No it's called a slap round spiking nearly 3x what standard pressure should be. It wasn't the rifle imo, it was definitely the ammo. That said, I would venture to say it did prove to be a safety design flaw- that is, *if* a detonation happens, the cap and ears that lock the breach have nowhere to go other then towards the shooter.
That said, I think the rifle is a "good design" (I'm fairly sure it was designed by Royal Nonesuch working with Serbu), but needs a safety improvement just in the case of a detonation.
@@APGT90 That rifle is a glorified pipe cannon at best, so I wouldnt go around calling it "a good design". Also, if you knew anything about thermodynamics youd know that pressure ALWAYS takes the path of least resistance. Slap rounds are jacketed in a polymer case thats designed to fail WELL below what the failure point of the barrel should fail at. If you were right and it was a pressure spike, the polymer sabot around the SLAP round would have been destroyed and the pressure would have vented out the front. If that round was filled with anything short of c4 it would have vented the pressure out the front.
@@DaHoodedBandit Right, that's why there's videos of all types of rifles of all brands blowing up bc of bad ammo. Because all gun manufacturers are clueless to "thermodynamics". By the way, you probably meant physics, but I digress. Wrong gun powder = big boom, the end
I like how the Edwin science channel can just answer all of my questions about science... Thank you Edwin Science Channel
Thought this would be another Kentucky ballistics incident, at least they're both good
Serbu did nothing wrong and it was definately ammo related accident. Mark makes really nice stuff.
I love you and your science channel so much edwin, thank you for everything you've done and will do. Take care and keep being a science man
Whenever you look for the spent round I always say to myself. Imagine someone came up with a device that you hover above the ground and beeps or vibrates even, when above metal. Someone could make a ton of money making something like that. Great video! Haha
Well moste of the so called metal detektors would be quit hard to use on a range, way to many signals there, but mabey a pinpointer could help them in some smaller Áreas.
And THIS is why I love your videos so much. You and Scott always make me laugh.
That rifle flew so gracefully. It was beautiful.

Scott used a bad round. I've ran 1000s of rounds thru my g19 but when I ran some reloads I bought from a friend of a friend of a friend my shit blew up too. Luckily I wasn't hurt

It shows Scott had a bad round. Not the rifle's fault.
Exactly what I was thinking
Yup... a VERY bad round
What? He didn't even use the same rounds.
Exactly, Scotts round must have been wayyyy overloaded, probably with the wrong powder.
@@Miohunter444 exactly this was the reason, scot explains it in his video
"Idk, because I'm not scientist... Oh.. wait... I am scientist" 🤣🤣🤣
the title should be "I BLEW UP MY 50cal RN 50"
not clickbait enough
This is a testiment to Marks engineering skills, I would have never thought the Breech would hold up to the 50 cal being stuck in the concrete, I'm blown away y the strength of Marks guns, makes you wonder what was in Scotts slap round for it to catastrophically blow up the rifle! 🤔😳
Militaries hot loading speciality rounds...for specific weapons and enemies.....then if surplus and not used, they sit for ages and end up as retro ammo on online exchanges....I would vet it would ve hard to recreate the rounds load quality ,quantity and shelf time temperature changes....if one could though and control the round with the serbu killer load accurate and precisely every time...in a beefed up chamber/weapon....f-ing a that round and weapon system combo would take the spot as "America's armored enemy killer" all day every which way...
Someone misread smokeless powder as nitro glycerine lol
I'll bet it was a SLAP reloaded with pistol powder.
Jason Miles Or a booby trapped round intended to be left behind a warzone for the enemy to find and use.
@@MildMisanthropeMaybeMassive no record of such for .50 cal slap rounds. give you a hint that is done for comm block rounds

It’s so cool to see how close the firearm community is on RUclips. Everyone seems to know and be good friends with everyone else.
To me, that's proof to all the people saying the gun failed, it wasn't the bullet, are wrong.
Yeh, everyone who knows anything know it was probably the powder of the round.
@@Jexorz86 No shit, I thought this had been cleared up months ago. There's still people out there arguing that it was a weapon failure after all the evidence? How do they remember to breathe?
@@danmackintosh6325 no because Mark hasn't fully said it wasn't the rifle. Most people know a obstructed barrel will explode the barrel. But it needs to be shown that the barrel is a weaker link and something went wrong before hand
@@Deere2154D I think this video shows pretty well what part of the RN50 is the weaker link. Definitely would be interesting to rebarrel it and continue abusing it with obstructions though.
@@danmackintosh6325 iunno. it might even make sense if it was just that one round that was off. but he had multiple problems before it happened, so maybe in that respect the gun could have been a contributor after it was already damaged from one of th previous shots... but either way, still 100% the ammo's fault
Mark serbu if you see this comment, I never doubted the quality of your product for a second! I knew it had to be those rounds.
DAMN that thing is powerful!
Can anyone else imagine having the connections to just blow up your .50 cal to make a point?
Buddy, you’ve got either an awesome liquid income or AMAZING friends.
It takes 30 days for concrete to reach full strength. You can see how much moisture was still in the cement so it could not have been fully cured.
Bingooooo,that's right,the concrete was not cured completelly,it require at least 28 days on 20°C avg,but total curing time of the concrete is actually around 50+ years...
doesn't really matter in this case. it was still a significant barrel obstruction. Now we need a test similar to this with a round loaded with fast burning pistol powder.
Not arguing about the time/strength thing, but my (late) brother was a civil engineer and told me concrete columns 50 years old indoors in malls being torn down were still damp in their middles. Apparently all the water does not get used.
@@Fuzzybeanerizer I hear you I was in construction for 40 years and have seen some things too.
You two are nuts, I love it
I knew from day 1 that the RN50 from Mark was not the problem. It was obvious it was an ammo problem they just kept getting hotter and hotter each shot. This proves something I already knew mark makes great firearms and I'd trust them I never stopped. Just make sure you use good new ammo in your gun unless you made the Ammo and you know what your doing. All gun have the potential to blow up and they do at times it is rare but can and does happen. So every make sure you keep your guns in good working order inspect every gun you get if you don't know what your looking at take it to a professional gun smith and always use ammo you know is good and what it's supposes to be.
0:50 Every gun channel needs a concrete company sponsor! LOL
WOW! This raises some serious questions about the equipment Scott was using at the time of his accident.... The power in those slap rounds must have been off the chart if a completely blocked barrel cant even remove the breach cap as happened with Scott's rifle....
Yall are so wholesome.
I am buying into the theory that Scott’s Slap round was loaded HOT with PISTOL powder and bullet wasn’t seated properly
That seems to be the most likely theory considering the pressures needed to strip those threads off the cap. It boggles my mind the amount of crap people are spouting about what they think happened.
I think the same
@@omnomshibob The most likely theory is that the round was a little hot, and the heat treat on Scott's rifle was bad. It held up to regular use, but the ears and threading were too brittle for that hot slap round. The rifle was probably the problem, and that round was the catalyst.
Also, the fact that the muzzle flashes were unusually large
Really great you comment on Scott at Kentucky Ballistics. He was very lucky.
Firing that .50 into the dirt looked like something from tremors. Y'all get a graboid?
Reminded me of the ground penetrating sonar rig from Jurassic Park.
😂 😂 😂
I wouldn't send it back either man 😂😂😂
(especially with a friend like Mark).
This is a "Favorite Collection" piece right next to some of the rounds and stuff 👍🏻
These dudes really are legit scientists because they go through the steps of the scientific method most of the time. If they could provide peer-reviewed scientific journals, they would have a a chance to get published. Lol but anyways your videos crack me up
"Science b**ch" 😂
Great video Edwin
Yeah at this point I'm fairly confident that slap round was extremely bogus somehow.
100 dollars means Bubba is going to use five bucks to make ninety five smackers at the gun show
EDWIN: HAS EVERY GUN YOU POSSIBLY WANT, BUT DOESNT HAVE A POCKET KNIFE. LOL
Apparently, you have never seen how fast a bucket comes down when a hydraulic line bursts.
I thought the same. Not worth the risk by being under the bucket!
oof yea didnt realise this at all,,, but thats gonna give a good whallop..
Not sure, but it looked like he wasn't directly under the bucket. Cameras really mess with the viewer's depth perception. Edwin seems to be pretty careful with the serious stuff although he hams it up for the camera.
Watching this video erases any doubt that i had in my RN50 breech as i have the same model as Scott did with the heavy barrel. Also a very fun rifle to shoot!
Impressive test, goes to show you how well built that gun is, and definitely makes you wonder about the ammunition (slap rounds) that Scott over at Kentucky Ballistics was shooting that day!
That’s gonna make for a cool wall hanger.
Thanks for the science
Respect to the manufacture of the RN50. He obviously wants to show that his gun isn't a death trap. Good test, any gun could be expected to blow up under similar circumstances. Avoid SLAP rounds but most 50 cals will be good.
Can't wait for the sawed off 50 video! 🤣
The mad scientists and his assistant making dangerous experiments! 😜
Boy did I underestimate the power of the .50 BMG! 😱
Lol, that was awesome. Loved it👍👍👍👍
I love y’all’s channel, but plz don’t do this to Justin’s .50 BMG bushmaster, at least I think that’s what his is. Or maybe a party popper in a buried .50 like this video but maybe mr. serbu will help with that, here is hope for you guys
I absolutely love this content Edwin
Hey guys just a thought, how about bringing a thermal camera to help find close by rounds 🤔
Well, the breach isn't the weak point for a barrel obstruction...
"I'm Ready!" - God I love you guys! Two better scientists there never were.
i was like oh no, not another one, what happened this time.
then 1 second in i see the barrel stuck in concrete...
So well done, you figured out several ways Scott’s failure didn’t happen. Well done. Not being sarcastic, This is how questions get answered.
After Scott's accident I hope NO ONE ever fires another SLAP round again.
Yes, it was a good round for its time. It still is, for sure. Yes, it is a high performance round. Yes, it's very rare and very cool. But given Scott's accident, I don't ever want to see anyone fire one of those again. RN50 or Barret or whatever .50 BMG rifle, no one should be shooting those rounds. Let's just stick to the typical red, black, and silver tips. They are entertaining enough. No content creator needs to risk their life with some SLAP rounds.
Thanks for mentioning Scott's situation a few yrs ago. That shrapnel was doing it's evil best to end him. IT DIDN'T!!!
HAPPY NEW YEAR EDWIN!! 🎉
Scott blew up another one just a couple of days ago it blew up just like the first one!
The explosion and destruction was identical!
It was Awesome!
Scott at Kentucky Ballistics knows how it's done!
Ah so it blew up because you made it. LoL
this just goes to show how hot that round was that scott had insane!
I thought scott said what caused the 50 to malfunction was the slap round
This an excellent example of how tough Serabu firearms are, takes a misload similar to handgrenade to blow the breach nut loose. Awesome video and even more awesome gun, I'll definitely keep using mine..!
Why not use a slap round to make the experiment as close to true as possible?

You guys are entertaining to watch even though you are serious about what you are doing.👍👍👍
That concrete was still pretty green ie. Not fully cured. Entertaining vid though.
It cured a week you could drive a truck on it
It's still massive barrel obstruction
@@joeklasen2845 I agree. I’ve poured Reinforced slabs and had heavy equipment drive over it within a few days without damaging it. It all depends on type, psi, thickness etc to determine cure times.
But his column was so green that it at one point crumbled when he picked up a piece.
@@akaknowlesy10 Over here, concrete is cement, sand and aggregate.. this concrete looked like it was different?
Edwin made a volcano crator in ground giving up smoke 🤣👌
Looked like really, really weak concrete, it looks like it also froze, basically a cookie.
concrete is pretty weak anyway without reinforcement.
Are you related to Gordon?
Concrete isn't concrete isn't concrete. There is rock bottom grade cookie dough concrete and there's super crazy high psi concrete.
I think it was fine, just in a sealed container with a cold temp so it didnt cure properly.
Best science channel. Thanks edwin!
The barrel is obstructed, you say?

"OK are you ready?".... "I'M READY!!!!"
This is probably the best demonstration of the energy of a 50 cal round.
Edwin: "Fire in the hole"
*The RN-50 literally firing in the hole*
Thanks for the video you remind me of my friend Jose and the just put a thumb in it Man God was really good to him 🤙🏽
You proved to me that the RN50 is one tough rifle. The RN50 rifle held up much better than I thought it would. I think you have definitely proved that the RN50 can handle any type of hot or cold 50 caliber round. The action and cap are very strong. However, you have just proved to me that the KB explosion was totaling due to a 50 BMG Caliber Case Head Separation Failure. That is a big fat total case head separation, not a little smile on one side. This is a common failure from bad brass created by reloading too many times with head spacing for autoloading. KB’s round could have easily been a round reloaded one too many times with adequate headspace for autoloading. My concern is the RN50 screw-on cap style action is not strong enough to handle a round with total case head separation. When total case separation occurs the gas leaks past the cartridge base and leaks out around and back of the chamber and bolt causing varying amounts of damage. In the case of the RN50, the gases leak into the area inside the cap and are sealed in. These sealed-in gas pressures can easily create backward forces on the cap that exceed the stated design limits of the threads holding the cap on.
Man, that second shot was the best noise suppressor I've ever heard. Real marketing opportunity for you there, Edwin!
I love your ideas and creativity... literally bkasts everything.. thumbs 👍for you guys.
I believe Scott used a loaded SLAP round that was very hot, and the standard barrel on the RN-50 isn't designed for it. Thats why he upgraded to the heavy barrel designed for the full auto 50bmg. But, it could happen to any rifle. I for one love my RN-50, I have always wanted a 50bmg, but the Barrett was a bit out of my price range. When I found Serbu, I immediately ordered one. The couple months wait was definitely worth it, plus I had watch 50calval on here when she was posting. Lastly, always check your firearms before using. Never know what could have gotten in the barrel and checking them before firing is good insurance, oh I'd keep that one too, a new rifle should be sent for future research 😉
