- On this episode of Ultimate Barrier Testing, we will be comparing the performance of the 300 Blackout to the 7.62x39 on 4 different targets. Each target is worth 25 points, for a grand total of 100 points. Whichever cartridge ends up with the highest score will be the winner. Testing was setup at 50 yards. Thanks for watching!

Not even a little surprised that the sand stopped both. There’s a reason militaries all over the world use sandbags.
Was about to comment this
Dirt is the best at stopping bullets and 💣 its why people like to hide under mountains
@repentandbelieveinJesusChrist1 Jesus needs to bless me with more money bro
@repentandbelieveinJesusChrist1 I don’t have anything to repent. The idea of inherited sin is absurd.
You're born into the world a sinful person. Even if you don't believe that, You're a sinner. We all are. We do it daily.
When doing these tests, I think you need to keep in mind the tests done by Mythbusters on shooting targets underwater; The bullets with MORE energy were stopped MUCH faster than bullets with lower energy. The .50 BMG disintegrated after less than a foot of water! The 5.56x45 did the same, so too did the 7.62x39. The 9mil, on the other hand, was able to penetrate about 5 feet of water, before losing all its energy. The bullet remained intact, while the more powerful rifle rounds were shredded.
The sand here seems to be an acceptable substitute for water, in that the results appear the same.
It's interesting that with bows, a 50% let-off bow has better range and energy on target than one with, say, an 80% let-off. I'm sure there's some physics that explains that, but I failed chemistry class in HS, so.....yeah.
@@dhession64It's simple, when you hit something, that thing is hitting you at the same time. The more force a bullet delivers, the more force it suffers.
@@irishkorean3479 every action has an equal and opposite reaction....Newton strikes again. Thank you for reminding me of that ☺
@@dhession64 i really like the way @irishkorean3479 phrased it.
Your reply reminds me of a line from the Hamilton musical 🎼 😁
Your editing skills are greatly improving. The big plus I like about 300BLK is you can have 110 to 220 grain projectiles with FMJ all the way to wild hunting and self defense tips.
A while back Gorilla was selling and 80 some odd grain super round that was moving about 2500 fps
110 grain Vmax rounds are nasty out of of my 8.3 inch 300 black out SBR.
There are 96 grain rounds that go 2500 fps

The strength of 300blk is that it can have a super wide range of loadings and applications. But that also is its downfall since some people will improperly compare soft led subs designed for maxium energy transfer to steel core 7.62x39. If you get the right loading, 300blk can be a very good barrier penetrator.
Which is true for any cartridge
The weakness of the 7.62 is that it can have a super wide range of loadings......😅😅
and another weakness its very low cost, and its a nato round... 7.62 needs to be forgotten@@jackjederstrombergman4987
That's true of ANY cartridge including 7.62x39 🤦♂️
We haven't had steel core for years...
If you have the same bullet weight being chucked at the same velocity you can only expect similar results
Exactly..basic physics..they have to know though my guy
Assuming similar bullet construction, I agree.
@@davehart7943 he is he summed up in one sentence what the fool in the video tried to do. Then no mention if both were fmj or otherwise.
That’s the thing - that’s the point of these videos - I’m fairly certain I get the point of your video - but if the results being measured are simple: PASS/FAIL… then the lesser cartridge passing would sort of negate the point of this comment.
Load data, 300 BO 125 grns 2250 Fps, 7.62x39 123 Grns 2450 Fps
300blk was designed for close quarters anti personal, specifically to be suppressed. With use with a ar platform, without having two types of magazines.
100%. My 300BO is my home defense weapon, suppressed, 8.5" barrel, 194gr Lehigh Max Expansion rounds, and they are terrifying LOL
@@danwest268not worried about over penetration?
@@scodyt3996 They do a lot of damage fast and then dissipate to cause massive internal bleeding. Even if they have a vest, shoot for the legs, you'll most likely hit some good arteries. Paramedics will call them on the scene LOL
@@scodyt3996 From 300 BA??? You won't get over penetration from JHP defense rounds.
@@danwest268lol don’t aim for their legs you will miss. Aim for their gut/lower torso. Vests only cover the top half of the torso the bottom half is generally unprotected and has tons of giant arteries the spine and the pelvis which all act fantastically when hit with bullets.
I think the winner is which round is cheaper to buy, and if I’m not mistaken the 7.62 is 1/3 the price for the most part, so with that being said it’s the 7.62. Great video, well done
I don’t own anything in the AK platform but it’s cheaper for me to get a 16” upper to fit my AR and I’ll eventually figure out the break even point.
I form my own brass from Range 556 and reload 110 gr V-max for about $.45 and with cast, powder coated, gas checked bullets it’s even cheaper.
I get 110 grain vmax from palmettostatearmory for $13 a box.
So you mean the 7.62 by 39 and not the 7.62 by 35?
@@Iceberg050So for all of that effort, you're spending about 50% more per round? Thanks for the heads up.
Looking at the data on both cartridges (before) the testing they are pretty darn close in comparison. The difference I like is the 7.62x39 has a reasonably lower data point when you purchase 1000 rounds. My humble wallet needs to feel the difference so I can blast away without breaking the bank. Good video.....I like your sleds!
You got it. I'd only get 300 if I wanted to tinker with custom loads.
300blk is only about 10c more than 7.62x39 right now, and x39 is just getting more expensive.
@@marcusborderlands6177Seems that the Russian ammo is finally drying up.
And I'm not sure if you can get a AK below 1050fps to be fully suppressed and be accurate.
Perfect demonstration of brittleness with the concrete + plywood, versus the sand. Sand disperses energy throughout; concrete has to absorb the impact in a relatively small space.
Get a suppressor and subsonic for 300 and your gun is practically dead silent at 100 yards. Biggest W yet
So glad they came up with a 7.63x39 alternative with the almost the same velocities at every bullet mass and a slightly different shape. The solution we did not think we needed for the problem we didn’t think we had.
If there wasn't such a crazy price difference with ammo, I'd understand it more. It's cheaper and easier to chamber an AR for it and it suppresses better and it's easier to find well manufactured rounds. Not sure if there would a big difference in soft target tests using similar bullet weights and constructions.
for three times the price!
Sarcasm?
@@ogkandyteeffit's 10c more...
@@geronimo5537it's literally only 10c more on average
The 300 blackout is scary quiet both firing with a suppressor and you can hardly hear the bullet move through the air when being fired out from a distance, it was one the calibers Garande Thumb used to record how it sounds to be fired at and they were actually hiding in a safe spot so they could hear and react to it first-hand. The .45 ACP made some of the most noise as it goes through the air. It's also powerful because of the size and weight of the bullet, good down range. It's so good for it's intended purpose.
Well, that was fun and entertaining - But, I think the 300 B/O was the 223/556 upgrade for CQC. So, if all I need to do is swap the barrel to shoot a 308 FMJ, then the 300 BLK gets my vote.
No. You will need an AR 10 lower to shoot .308.

I’ve always enjoyed your videos but I’m really enjoying where this channel is going!
I’m digging on your videos and testing….but, don’t forget to try testing your samples at distances as well. Obviously the strength/velocity may begin to lessen, I’d be very curious to see which calibers maintain solid velocities at 100, 200, or even 300+ yards. Many thanks for the great quality videos and your entertaining style!! I’m sure you’ve gotten countless compliments on your amazing vocal qualities, as an “ex”-radio producer you have an incredible speaking voice for voice over work!! 👌🤓😁😇

First i can see your fabrication skills are excellent. This is my fist time seeing your channel and my observations are this.
The window booth shooting station are top notch along with the railroad ties for safety remond me of how i always envisioned myself designing my own range.
The sleds are executed very well and i saw the detail before you started the demonstration.
Excellent presentation, thanks for sharing.
I just randomly ran into this channel and this video was really well done! surprised to see you dont even have 50k subs you definitely deserve more so im subbing! Keep up that good work.

Youre making a good argument for me getting a 300 blackout bolt action.
Me too. No gas-balancing hassle, cast bullet friendly, no chasing brass, powder economy with poofter loads for the grandkids to use, the only minimum velocity is whatever will make it out the barrel and to the targets. My eldest son wants me to build an AR in 300 for training his son and new stepson, but I'm holding out for a bolt gun. I've had enough gas system drama trying to get my AR450 to run right.
I decided on 7.62x39 on an AR platform. I stick to AR because virtually every part save the bolt are common between my ARs and the main reason was 7.62x39 is so readily available, cheap and the ballistics are significantly different.
Significantly better than .300 blk out? 5.56 ?
Can't go subsonic though.. can't interchange mags... And I noticed 7.62x39 doesn't seem to run as smooth on the AR platform as 223/556/300BO.
Just my experience having used both
Took me a while to find the right mag/ammo/bcg combo to get my build to run reliably but it’s my favorite to take to the range just because it doesn’t cost a fortune to run for an afternoon. Most of that cheap Russian ammo have hard primers and I still get a light strike occasionally but it’s rare now and only with certain Tul types, shoots the domestic stuff just fine. It also performs better than the 5.56/.223 in shorter barrels for pistol platforms.
You can go sub sonic with 7.62x39 , its just not common compared to 300. though i'd argue neither are really "effective" ( granted 300 blkout has a better projectiles for this) at being subs , something both RUS and the US have figured out with 9x39 and 8.6 blk out.
@@motog1115
@motog1115 7.62x39 Absolutely can go suppressed & subsonic... it's the Ammo used that makes it subsonic.... a suppressor helps supersonic ammo sound less loud in any caliber
....most common 300BLK isn't even subsonic... can't really interchange Mags(you can use 30rnd 5.56 to fit like 4-6 x39 rounds but CPD/Duramags work great in 5-28 round capacity)
The cost per round and negligible difference in ballistic performance is a real advantage to the x39.... but the blackout is great too... if your pockets are deeper
Excellent video today, thank you and also to Midway USA they have gotten thousands of my dollars over the years, before age caught up with me.
Awesome day when I see a new video from you, man!
Thanks for all your time and work!
Sure Man thanks ..It means a lot.
I never thought I would hear the music dankpods uses to test headphones in a different video, but there it was in your intro. Starts at 0:15
Your wonder sled is a pretty cool design! You could try cutting you 3/4" plywood into strips, so you could slide it back and forth, for clean spots to shoot vs. Small disposable squares.
Ya need to shoot more than one round of each in each test. You can have widely varying shot to shot results shooting through different mediums/barriers.
As someone running both calibers, I can say that I will choose my 7.62x39 CZ 527 American over my Christensen Arms 300 blackout every day of the week. I run similar bullet weights in each, 154gr in 7.62x39 and 150gr in the 300. They both do the job on all Florida game, but the 7.62x39 does it with more authority and for cheaper. I bought 400rds of 154gr JSP for my 7.62x39 for the same price as 80rds of .300 blackout 150gr JSPs. If you're running suppressed obviously there are some nice .300 blackout loads that make a lot of sense. But stick to semis as a lot of the boutique ammo manufacturers use military primed brass that only works in semi-autos reliably. I ran into this for the first time buying ammo from Gorilla Ammo with their 205 grain solid copper bullets.
that sort of confirms what I was thinking about the two calibers, 300 is better for specialty loads and odd setups whereas 7.62x39 is better as a general use. I think the argument ultimately stems from the old AR vs AK debacle tbh.
@@edwardoavila7666 you could be right but now that we can get AR uppers in both calibers it may be a moot debate. I was looking at an Ruger American in 300AAC the other day but was unsure of the difference in ammo costs were without some research. After looking around and seeing this video I think I’ll stick with the 7.62x39 since I already have that.
@@peternorton5648 the reliability of AR uppers and magazines for running 7.62x39 is called into question when compared to the AK platform. If you only run AR’s, then 300 is probably the better option
I waited until Blackout got more accepted and it was obviously not going away the way of many wildcat cartridges. I"ve been carrying a suppressed 8.25" AR on duty for the better part of 10 years. As newer ammunition comes out it just gets better and better. The current LE only SBR round expands to .75" and only penetrates 16" of gel, excellent expansion and little to no over penetration. It's a much better round for LE use than 5.56. We have yet to find a real performer expansion wise in subsonic, and our testing shows massive over penetration with a 220 grainer even at only 1,050 fps.
The Lehigh 194gr max expansion, the Hornady 190gr Sub-X, and the Maker Trex bullet are all great in subsonic 300BLK.
I think the 300 blk lends itself well to being a wrecking ball due to slow heavy mass. Less likely to tear itself apart like some high velocity calibers
. 300blk: the .45 ACP of rifle rounds.
There’s one thing that sets gun videos apart, one that separates the ordinary from the distinguished: whether the star/host thinks that the written “vs.” represents the sound “vers” or the word “versus”.
Those are some really clean welds my brother!! Excellent shooting too!!
7.62x39mm and 300 Blackout aren't really competing cartridges. The 300 Blackout was designed primarily to be an effective subsonic round that could be fired from the M4/AR platform short barrel rifles with the fewest possible parts changes. The 7.62x39mm is available in subsonic, but it is a modern day afterthought, and it is about double the price of 300 Blackout subsonic. Unless an ammo manufacturer decides to pump out enough subsonic 7.62x39mm, to a point that it becomes cost comparable to subsonic 300 Blackout, then it seems to me that building or buying a 300 Blackout AR to have in addition to whatever AK/SKS platform you already have would be a more economical option in the long run. If you already have an AR platform rifle, then it's even cheaper. You just need an upper, and you can borrow the BCG and charging handle from the AR upper.
3:08 For years I always tell people I didn't miss my shots, they go through the same hole. Finally someone else is doing the same.
Straightest thumb in the industry. 10/10
I hate when bullets do their own thing. “Go away” was classic
Your content just keeps getting better
That post-sand 7.62 gave that plywood a serious mushroom welt.
The 300 Blackout is primarily a subsonic round. Using it to compare against 7.62x39 is comparing two calibers with completely opposite characteristics. The 300 blackout has a much larger range of bullets that can be used versus the 7.62x39. Such as 90 gr to 240 gr. My favorite is a 210 gr cast powder coated bullet with 11.6 gr of CFE BLK with a 10" can and an 8" barrel at 1050 fps. A very lethal and very quiet round for shooting feral hogs.
300blk was designed to go between supers and subs in short carbines
Primarily? That's your perspective which is fine but I primarily shoot 125 gr or 110 gr supersonic ammo.
Ammo type matters;
I have shot Tula 7.62x39 124grain and it tears up targets.
.223 Tule 62 grain with the same steel jacket only make a small dent.
300 AAC blackout 200 grain subsonic with a copper jacket has the most drop and least penetration.
300AAC blackout 125ish grain has similar balistics as the 7.62x39 Tula, but tends to have similar penetration as copper jacketed 7.62x39
These are just my observations while shooting.
absolutely love the new tests, keep 'em coming
Fun time! Well done and I love the constant evolution of the sled! I think Bullet construction with steel core (even a softish one) would make the real difference - and I'm not aware of any steel core 300 BLK but plenty of that for 7.62 x 39 still available. If that were the case, the dice wouldn't be the final judge - I think the 7.62 x 39 would have the edge and be the winner...
Ps I love both rounds but the 300 BLK is my suppressed round choice - the 7.62 x 39 is what I would choose for both "manning a roadblock or running one... " 🙃
You should do voice acting.
As it was designed almost entirely for CQB/Urban warfare, I'd expect the 300blk to be limited in barrier penetration. Also, it was designed for subsonic work as well, and that would be non-existent penetration most likely.
It’s a good AR platform round in heavily wooded areas as well. Also more effective on medium sized game out to 300 yards than the 5.56
300 black in the barns tts or ttx will smoke a white tail at 300 yards and perform better in brush than a 5.56
The 220 gr subs out of the .300 blk still hit harder than most handgun rounds, and supersonics are nearly identical to the 7.62x39 ballistics wise.
Urban environments are exactly where you'd want barrier penetration the most. Open desert battlefields aren't exactly full of walls
@Superabound2 you haven't done much CQB have you
.300 BLK was designed to have similar performance to the 7.62x39 in an AR platform, so no surprise that they are close in several performance points.
If you have everything the same then you don't need to compare, crunching numbers, to many variables, the simple solution is the 300BO was designed as a suppressed cartridge out of an AR platform, whilst the 7.62x39mm is a standardised military cartridge, now potential handloading in a single or bolt action with same barrel length, rate of twist, same projectile, powder,etc., the larger powder column has always more potential for energy output, so comparing these two with the variables the 300BO would be running at much higher pressures with hotter powder than the 7.62x39, at the end of the day it's a matter of choice or buy them both, don't compare platforms, marketing or labels, they were both designed for their intended purpose & will do the job 🍻
Ret Vet 👍🌅
While the ballistics show the 7.62x39 flying a little faster, I can see all the advantages of the .300. Lots of loading data using H-110 propellent. Huge selection of bullets. It performs equally well from a pistol length barrel (9"-12") as it does from a 16" barrel. It's an easy swap in the AR platform, even uses the same mags as the 5.56/.223. The cases I've seen are all small rifle primer, as opposed to the 7.62x39 cases using large rifle primers.
300blk and 7.62x39 are almost the same. The real difference is that 300blk was designed to be fired out of an AR platform with a specialization in performance from short barrels and suppression. In my opinion if you’re gonna buy a 16” barrel rifle and you want something in the 30 cal variety then the best option is 7.62x39 because it’ll have nearly the same performance as 300blk but it’ll cost a lot less.
Exactly what I expect from any .30 cal battle rifle. I'd go with the 7.62 because the ammo and the guns are cheaper
Awesome video, great testing however, the wood block testing is flawed after it has been compromised by a single impact. I know you already know this.
300bo not subs running fmj is a penetration beast! It's designed to dump everything in the target with a hollow point tho.
Results are because of mainly sectional density. The average bullet weight of the 300 blackout is 220 grains while that of the 7.62x39 is only 123 grains. Given that I would rather hump around the lighter cartridges in a tactacle situation than the doubly heavy blackouts that may cause you to blackout because of the stress / fatigue of carrying it over long distances.
Just for a giggle you could see if they beat the old 30/30 🤷♂️😊👍.
My 1st video I've watched of you because of a youtube recommendation, in another life, in an alternate universe where Ray Romano didn't become a standup comedian. Instead he just films himself shooting shit in his back yard, and I'm loving it!
I’m pretty sure the entire point of designing the .300 blk was to come up with a ballistic equivalent to the 7.62x39mm cartridge that worked well out of the AR-15 platform; so, yeah this result makes sense.
can you do 7.62x54r vs 7.62x51mm please
Good tests for curious civvies like me. The big lesson is what @Jason-iz6ob pointed out: sandbags exists for a good reason! The second lesson: armour your vehicles.
_(Yes, I'm a pure civilian. It's good to SEE the reasons, though!)_
Is it just me, or when he spray paints the metal... all I can think about is how shabby the job is :)
Keep up the good work.
IMO if the 7.62x39 hit more rock in the concrete test that would of slowed it more than the blackout! The steel test is more telling of what round has slightly more energy!
And velocity is king on steel
Your test target holder thing-a-ma-jig just keeps on getting better.
Here's a good way to change anyone's mind and make .300 Blackout better at the same time, though it will involve some money, materials, tools and time. First going to need a couple of Crucibles and a Steel melting pot (melting pot is just in case, you decide you want to add a Steel, Aluminum, or other metal for a core, generally going to use a Crucible for melting a soft metal for a general Bullet core ), going to need molds to make solid Bullets, and molds for making Full Metal Jacketed Bullets, going to need Bronze for either Bullet type and Lead or Fools Gold (good for Lead free zones and has same properties as Gold and just as abundant as Lead) for regular FMJ Bullet cores, going to need a decent Rock Tumbler or Sonic Vibrating Cleaning Rig for deburring and smoothing up the bullets, going to need a welder and cooper wires for the Jacketed Bullet Mold (going to make it so you can Electro Bond the Jacketed Bullets together. I suggest looking up how to make an Electro Bonding Rig, that's how I made mine it's not difficult and has other applications), lastly going to need a proper ammo press. Solid Bullets are simple, Melt Bronze and when melted pour into mold, let cool, throw into Rock Tumbler or Sonic Cleaner Rig (don't use water or any other liquid in the Sonic Cleaner Rig use the same type of deburring and polishing stones one would use for the Rock Tumbler), use ammo press to make ammo like normal ammo bench use and done for Solid Bullets. Jacketed Bullets are a little more difficult and require extra steps and care. Melt Bronze in Crucible. If you want the Bullet to have a bit more strength add some Aluminum to the Bronze, or some Industrial Strength Synthetic Diamond Dust (can get that from certain types of Commercial Drill bits, though this will take time and effort), or both materials to the Bronze. A word of caution here this Bronzium mix will tear a Barrel up if used for the Bullet's Jacket, using it as a core, or even a base core surrounded by a Inner Jacket (Jacketed Bullets with a soft metal inside underneath a Jacket with a tougher core of harder metal of Bronzium, Steel, Aluminum, or other hard metal) will be just fine on Gun Barrels. Pour into melted Bronze into Jacket Mold and set to the side and let cool. While the Jacket metal is cooling melt some Lead or Fools Gold in the Crucible, when it's melted pour into the FMJ core mold. When both Jackets and Cores are cool, put into the FMJ mold (Top Bullet Jacket half, then Soft Core or Outer Soft Core Half followed by Penetrator Inner Core if making a Penetrator FMJ Bullet, which is made almost the same way as an FMJ Bullet, requires the Core to be made in half's instead of a whole in order to accommodate a hard dense metal for a Penetrator Core . Followed by other Outer Soft Core Half, then the Bottom Bullet Jacket Half). Attach FMJ Mold halves, connect mold to Car Batteries (remember to place mold on a couple of concrete blocks and be careful as electricity is dangerous but useful), turn on for a few seconds (place concrete blocks or bricks evenly across top of mold to add pressure for a good bond). Last step is to take FMJ's to an Ammo Press and make ammo as usual.
The 300 BLK advantage comes from its wide range of available bullet weights and velocities. The 300 Blk I have was purpose built and has a 9" barrel and is loaded with 200 gr subsonic HP ammo. It is NOT supposed to go through anything.
So basically, .300blk is non-commie 7.62x39.
For me it came down to cost of ammo , at the time I could buy 7.62 for half the cost of 300blk.
now its the opposite
fun fact, u.s. military has a write up for how much sand you need to stop rifle cartridges. 6 inches of sand stops a lot.
762 wins because of cost
Speaking of cost, what made 223/556 jump up to even higher prices than just two months ago?
I ordered two cases two months ago, placed an order yesterday and it was $115 more per case! Standard practice ammo.
Also the four vendors I use only had one brand for case purchases.
Maybe I need to get into archery
@@HWG-wm8ld
The exact cause of 556 jumping up is not clear but a mix of
1. Ongoing Ukraine invasion taking some (ukies got a lot of 5.56 guns given to them)
2. Rumors of US Mil stocking up (lake city supposedly stopped civ contracts to exclusively support mil)
3. Now israel gaza invasion diverting some (plus scaring foreign jews into stocking up due to retaliation fears)
4. To an extent, ammo sellers/distributors trying to scare up hikes to print money again like they did with covid
5. Supply chain still reeling a bit from covid in general (primers still not down)
Did you not see the tiebreaker? 300blk once again showing its superior performance by winning a dice roll
Like I told you before, 300 blackout put craters on the moon. I'll take a shirt homie
I’ve been in love with 300 since the beginning. Here’s some more reasons for me.
My 300blk in 16"AR has taken plenty of hogs and bear out to about 130yards. No complaints and no lost game.
So, 7.62x35 versus 7.62x39...results should be pretty close. Now, to watch the video.
Sir, I really enjoy your videos and I'm subscribed but I think it's time for some constructive criticism right about now. Since I know that you love to hate on the 300 BLK, I'd like to point out something important. The 300 BLK was designed to run efficiently IN SHORT BARRELS LESS THAN 11 INCHES TO FACILITATE ATTACHING A SUPPRESSOR WITHOUT ENDING UP WITH A MUSKET. That's why that cartridge was designed. It doesn't have as much to do with "subsonic ammo" as people think it does. It's creation has been largely responsible for the huge increase in suppressor sales in the last ten years or so. People want a rifle with a suppressor that's the same length as a rifle without a suppressor. Add in the confusion of the brace fiasco and here we are. If you conduct the test with the same two calibers again and use 9 inch barreled rifles for both, then you'll get a real world result, if you can get the AK to run long enough to finish the test. If you want to shoot .30 caliber in a 16 inch barreled AR, then 300 BLK isn't what anybody with a brain would be shooting. 300 HAMR or even 7.62x39 would be better options. Don't try mud bogging in a Ferrari. That's not what it was intended to do.
And yet, it seems to be pretty popular for exactly what the "brainless" people desire: An AR platform equal to 7.62x39 AK's. Which.. this more or less is.
You’d be neutering the 7.62 round in a 9” barrel.
@@albundy7459 That's my point, not a fair test as it was performed
A gun geek says what?
It’s just for fun, banana ballistics…this isn’t nsa crane.
@@irwinfletcher2848 this round was made to do one thing. It’s always going to be insufficient to every round outside of silent close quarters use which no non military/police person is doing.
The sand was able to exit through the top and the energy of the bullet followed suit deflecting upwards. The lower velocity of the 300 was just enough to keep it from disintegrating in the concrete, where the 7.62x39's velocity was just enough to destroy the bullet.
So you know on metal targets you use steel cased ammo that there is also steel in the projectile of the 7.62 x 39. That's the reason why ranges don't let you use it. It messes up their backstop. Take the projectile out and it will stick to a magnet even though it's only supposed to be copper and lead. So a penetration test against steel isn't comparing apples to apples.
Russian Commercial steel AK ammo is not seel core
I think you should do that concrete test a few more times. I'm guessing that the 300 Blackout result was an anomaly and if done again would probably more closely resemble the the 7.62.
My thoughts exactly.
I know from many videos and data 7.62 is better on concrete and cars especially.
I wouldn’t doubt it either. The Russian has a larger case and more powder than the American. I think my takeaway is that the comparisons between these two are like the comparisons between 9 and 40. They’re in the same realm with similar bullets, so just pick your favorite, either one will work!
I don't know why you'd be surprised how close they are in velocity. The bullets loaded into .300blk(and, by extension,.308) are radically superior in ballistic coefficient to those used in 7.62x39. There's a bigger gap in ballistic potential between these two than there is between the 7.62 Russian bullet and those used in the 30-30. We put a lot more thought and science into developing .30 cal bullets than the Russians did. A LOT.
Ballistics data shows the 300 bo is almost identical with the old 30/30 deer slayer cartridge.
They look very different but share very similar numbers far as velocity, wound cavity, range and drop.
I guess 300 is a good buck round then.
That is not entirely true. With 16 inch barrels, 30-30 has a 150gr bullet travelling about 2300fps, 300blk achieves that velocity too, maybe even a few dozen fps more, but with a 110gr bullet, which makes it significantly weaker. Also, You gotta consider the fact that most 30-30 deer rifles have longer barrels than 16 inches, while 300 blk options practically end at that barrel length, which makes the power gap between a 300blk AR-15 and your "grandpa approved" 30-30 lever action rifle even bigger.
Now, I'm not saying 300blk won't take down an elk if you really want it too, (it's all about shot placement, after all) But it's not equivalent to 30-30 at all.

We compiled the data with as close to similar grained cartridges and same length barrels.
The 30/30 varies more in fps the longer or shorter the barrel compared to the 300.
Primers unfortunately we’re different and loads , although similarly stated by manufacturer, we’re noticed to be slightly different.
The point is that it was absolutely a surprise to us just how much these two inherently different cartridges from different eras, matched so evenly.
To the point of us building 300 BO rigs for hunting use.
The data is a spread sheet worth of information but there are a few videos here that show the breakdown in full detail.
I appreciate your input as well.
@@andrzejsobanski6752
Both were 150 grain and trajectory was the most interesting of the comparison.
Almost identical in range / drop but with a 200 fps detriment between the two.
Funs fun, and nothing beats playing with your freedom stick. However I hunt with a flintlock smooth bore. Max range fifty yards, beyond that I got lots of power but accuracy suffers.
I’m thinking at six to eight times my range both those guns will put meat on the table.
For all the foot pounds and mid range trajectory numbers one can geek out over deer don’t care as long as you get good shot placement
You should invest in a good slow mo camera. Like, ultra slow motion. Something in the 1000 fps range. It would be a literal investment but would take your already fun videos to another level.
I know the contest was between two potential peers, but would have been neat to pull out 556 on metal targets just for quick reference vs them both.
Who builds a 300BLK for supersonic barrier penetration?
It’s just a test dude, chill. Not everyone pretends to be an elite operator.
7.62×54r cartridges Army mild steel core ball 148gr..🇷🇺 Rus.

What a strange voice, seems forced lol
I'm glad you went back and re-shot he 300 Blackout into the sand. I don't feel like the test would have been accurate if the top of the box popped open and sand came out for one cartridge, and not the other. I also thoroughly enjoyed the tie-breaker at the end of the video. Keep up the great work! I love your videos!
Bullet construction is huge factor. Expensive , but hand load the 2 with lapua bullets ( equal comparison ) use & cfeblk or a 4198 middle of chart charge & then test. I think we know winner but a equal playing fiels for the 300blk anyway. I only have six .310 lapua bullets but couple hundres 123gr. .308 lapuas left. Wish i would have thought about it when i had nore lapua 123gr. .310 bullets. So many sub par jacket bullets out there in .308 caliber , same from 3rd world commercial factories, some are great but junk also. A true test. Would send u handful of lapua 123gr. .308 bullets( cut ur cost).
The 300 BLK has a wide application of uses and bullets being a .308 caliber. The 7.62x39 is pretty much a one trick pony with a .312 caliber barrel. The 300 blackout is capable of firing sub sonic with way heavier ammunition. In my experience subs penetrate a lot further defeating barriers better than supers.
Uni-Sled gave me a video idea. Use the uni-sled to angle steel plates and test penetration at an angle.
Thank you. No contest with good reloads. In cheap Chinese bolt rifle I safely got consistent velocities of 2350fps….with 174gr bullets. Look up 303 British. Sure..long loaded and drop tube powder charging….try this with the blackout. The reason for this development was to have a load capable of taking all big game besides the big five in South Africa.
Kinetic play sand has unbelievable stopping power . I used it for building a bullet trap in FFL I once held . 8x8 box packed 10 " deep with 5 front layers of cardboard . Could dump 50 - 65 rds center before needing to clean and repack . 😅 30-06 , .308 etc we would repack after 10 rds. 9mm , 22lr etc you'd be surprised how effectively it stopped projectiles.
Great comparison. Extremely similar in many ways when using the same type of ammo.
The concrete target was probably a difference between bullet construction of the two cartridges.
Here's something else to consider .My .300 BLK. will also shoot the same bullets I reload for my .30-06 ,it will use the same H110/W296 Powder as my .357 Mag. loads and I can use 150 gr. R.N. Cast Powder Coated LEE bullets I make for .30-06. None of these can be done with the 7.69 x39 and the AR15 Platform is more conducive to long range accuracy than the AK platform.
The only thing i had to prop my phone up to watch this video as i eat my dinner right now is a banana
Need a re do on the concrete test. Possible fluke. On the sand test where the top popped open, the sand was displaced resulting in much less energy being absorbed. This is why the bullet was not stopped within the sand. Regardless your test clearly show just how close these two rounds are. Choosing one over the other should have little to do with ballistics, unless you are interested in an very specialized custom load and much more to do with cost, availability and what platform you are using. Great video! Keep up the good work!
300 Blackout was designed to be shot from a 9" barrel for maximum performance.
I like 300 Blackout. If can be reloaded using empty 556 casings and it is more accurate than an AK round.
You have to use 7.62x39 with heat-hardened steel core 7.62 PP or 7.62 BZ or 7.62 BP and result will be different. You have to use armor steel, not regular steel. Penetration is dependent of what core in bullet and if it is AP and FMJ, penetration will be better.
One of the most entertaining! And informative.
Very entertaining! Nothing that you shot is what I bought my 300 BO for, but a good (and humorous) test.
When it comes to the range of projectile weights , the ol 30-06 hangs right in there. I load from the ballistics manuals 110 grain all they whey up to 220 grain. I think the 06 beats all the new fandangle cartridges.
Multiple tests have shown that between the 300 Black Out and the 762x39, is the superior caliber all around.
Years ago when the Chinese Steel Core ammunition was imported it was said to be very effective at penetration.
2A advocates should demand an end to the arbitrary and capricious GHW Bush Executive Order banning on the import of Chinese firearms, ammunition , accessories and parts, which were excellent affordable quality.
