@@Silentguy_ nah just pull the bullet out of the casing to examine and test the powder. then you can proper load the powder and set the bullet back in properly. the legit parts to make slap rounds were at one time available but Bubba being Bubba would use cheap powder and not set the bullet correctly.
I'm still shocked at Scott's 10 gauge shooting with a plugged up barrel, it even popped the breach open on one shot and instead of the shot pushing the dirt out or blowing the barrel up the shell casing shot out the back at mach 1 lol. I've known about dirt plugged barrels being dangerous for years but it's cool seeing the fact demonstrated on video.
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.
Thanks, seeing this video has given me confidence that if I owned an RN 50, I am reasonably certain is won't explode with normal use. Thanks to Mark for sanctioning this video.

@@michaelfeenin551 still needs a fail safe so when it fails it’s not catastrophic like KentuckyBalistics did. It’s been addressed in other videos what measures could be put into place to prevent it.
@@billyanderson321 A failsafe is certainly a nice measure which can increase the safety of a firearm should the mechanism itself fail for whatever reason (such as improper ammo usage or loading), however a lack thereof doesn't make a design inherently unsafe in my opinion if the action is strong enough for the ammo it is intended for.

@@exMuteKid well those saying the barrel was obstructed in ken tuck ball serbu were saying that was way the breech blew it up. anyone with a brain knew it was the ammo that was suspect and any counterfeit round by bubba will blow up the breech.
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.

The RN50 is not designed that way.

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
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.
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
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.
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!
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...
@@Angrykat420 What? Norinco made .223/5.56 aks, Type 84S for example. Norinco is a manufacturer, not a specific type of AK, they made tons of different variations.
@@sirdanielfortesque5812 Well, it looks like the guy who i was responding to, master daddy, deleted his comment, so now my comment makes no sense. lol. Someone responded to this dude that norinco wasn't a 5.56 AK.
I fully believe Scott had gotten ahold of some rounds that someone had messed with as far as powder type and/or charge. Sure glad he is still here and doing well. I figured it would blow the cement apart like that since it was more than likely not cured all the way, plus there's a big difference between straight cement/mortar and actual concrete. Interesting to watch just the same. Looked like the barrel split right along the lands in the rifling in the one close up from the side.
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.
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.
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.
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
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..!
@@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
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....
😂 😂 😂 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 👍🏻
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
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.
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.
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
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...
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.
Mark and Scott are great Americans.. 🇺🇸2A🇺🇸 We are fortunate to have them around. Wow, that concrete sure fragmented in the first shot. Good show guys! This was FUN🤣🙋
EDWIN!, I want to see a slow motion video of a round through that rn50 with no obstruction. The fireball that that barrel would throw now would be INSANE!
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.
Damn man, how can you not upload for weeks and than choose that title, I was really worried for a Moment 😂 Happy New year, stay safe, you and gaspari ✌️
@@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.
So about that theory of the sabot getting stuck in the muzzle brake blowing up the breech....😂 Great "science" as usual, Edwin!

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
You two are nuts, I love it
You guys are entertaining to watch even though you are serious about what you are doing.👍👍👍
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
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.
@@MrSpeedysChannel exactly this was the reason, scot explains it in his video
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.
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!
Somewhere in australia: “aye mayte, a bullet just jumped out of the ground mate! What the hell mate?! Shrimps & barby mate?”
G'day mite, ya lil rippa

@@FalloutProto i call them sea grasshoppers 🤢🤮
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.
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...
@@Angrykat420 What? Norinco made .223/5.56 aks, Type 84S for example. Norinco is a manufacturer, not a specific type of AK, they made tons of different variations.
@@Mcbuggler He never said Norinco was a specific type and not the manufacter, you projected that being pedantic for no reason.
@@sirdanielfortesque5812 Well, it looks like the guy who i was responding to, master daddy, deleted his comment, so now my comment makes no sense. lol. Someone responded to this dude that norinco wasn't a 5.56 AK.
I fully believe Scott had gotten ahold of some rounds that someone had messed with as far as powder type and/or charge. Sure glad he is still here and doing well. I figured it would blow the cement apart like that since it was more than likely not cured all the way, plus there's a big difference between straight cement/mortar and actual concrete. Interesting to watch just the same. Looked like the barrel split right along the lands in the rifling in the one close up from the side.
Dude that reloaded might have put pistol gunpowder, wich is hotter than rifle gunpowder
Can't wait for the sawed off 50 video! 🤣
DAMN that thing is powerful!
Legends bro is back🔥🔥🔥
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 🤙🏽
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.
3:11 suppressor obtained from concrete, wow that's innovation
I absolutely love this content Edwin
It’s so cool to see how close the firearm community is on TH-cam. Everyone seems to know and be good friends with everyone else.
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.
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
Best science channel. Thanks edwin!
That rifle flew so gracefully. It was beautiful.
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
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
I love your ideas and creativity... literally bkasts everything.. thumbs 👍for you guys.
You guys are hilarious 🤣 please make more on the cooking channel
Serbu did nothing wrong and it was definately ammo related accident. Mark makes really nice stuff.
It would be interesting to x-ray the threads on the breach after repeated severe overload like that or magnetic particle testing
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..!
Really great you comment on Scott at Kentucky Ballistics. He was very lucky.
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
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....
😂 😂 😂
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 👍🏻
Great video gentlemen!!!! Fascinating results. Please thank Mark for donating the gun. See you on the next one!
Best
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
Ahh yes my fav science channel
I am so happy you are ok. Thank God you aren't Scott 2.0. Thank God you and Scott are good!
Awesome test man!
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.
Hey guys just a thought, how about bringing a thermal camera to help find close by rounds 🤔
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.
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.
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
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
that bang cracked me up thanks!
this just goes to show how hot that round was that scott had insane!
HAPPY NEW YEAR EDWIN!! 🎉
Well, the breach isn't the weak point for a barrel obstruction...
"Science b**ch" 😂
Great video Edwin
"I'm Ready!" - God I love you guys! Two better scientists there never were.
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.
I thought scott said what caused the 50 to malfunction was the slap round
Man, that second shot was the best noise suppressor I've ever heard. Real marketing opportunity for you there, Edwin!
"Idk, because I'm not scientist... Oh.. wait... I am scientist" 🤣🤣🤣
Mark and Scott are great Americans.. 🇺🇸2A🇺🇸 We are fortunate to have them around. Wow, that concrete sure fragmented in the first shot. Good show guys! This was FUN🤣🙋
How to use Earth as a silencer.
Underrated comment
EDWIN!, I want to see a slow motion video of a round through that rn50 with no obstruction. The fireball that that barrel would throw now would be INSANE!
That brings a whole new meaning to single shot I'm still waiting for a semi-auto 50 cal with 20 round mag
Ah so it blew up because you made it. LoL
Why not use a slap round to make the experiment as close to true as possible?
Reloaded Using pistol powder
Damn bro, sorry for your lose😓
This is probably the best demonstration of the energy of a 50 cal round.
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.
The barrel is obstructed, you say?
Do tell...
EDWIN: HAS EVERY GUN YOU POSSIBLY WANT, BUT DOESNT HAVE A POCKET KNIFE. LOL
Damn man, how can you not upload for weeks and than choose that title, I was really worried for a Moment 😂
Happy New year, stay safe, you and gaspari ✌️
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?
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.
Edwin made a volcano crator in ground giving up smoke 🤣👌
There goes the barrel obstruction theory.
Solid af.
