300 Blackout vs 7.62x39: Never Would've Guessed

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!

You should do the same tests using 8 or 9 inch barrels. That is one of the main benefits of these rounds is that they still perform really well ballistically with shorter barrels.

[@shirothehero0609]

Absolutely. And not only that, but the 300blk was also designed to be excellent suppressed with that short barrel. Hence the more seldom used "Whisper" suffix. Testing rounds for performance and not testing why they were designed is a bit of a miss.

[@Raz.C]

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.

[@dhession64]

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.

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.

.300 blackout is the most underrated round. It can take Deer better than 5.56 and on par with 7.62x39. It can penetrate (within 200 yards) just as well as 7.62x39. It has a much wider range of bullet types (VMAX, Polymer, Soft Point, Hollow, Subsonic, and Supersonic). About the same weight as 5.56 and it fits 5.56 magazines. All the hate is definitely due to it being a new round. I'm pretty sure if anyone was shot with a .300 blackout they would be on the floor writhing in pain.

The velocity similarities are expected considering the 300 Blackout was originally designed to more or less mimic 7.62x39 ballistics (for supers). I believe 110 gr to 125 gr is a great sweet spot for 300 Blackout supers. Unfortunately a lot of people use 140 - 150 gr. They tend to be poor performers in every way compared to the light supers and heavy subs.

[@joshrandall3632]

The BO was never designed to shoot "supers" at all. In fact, it was originally designed around a 240gr Sierra MK bullet, way back in the early '90s.

[@JabariHunt]

@@joshrandall3632 You are likely referring to the 300 Whisper (which the Blackout took a lot of inspiration from). The Blackout was designed in 2009 by AAC, and one of the core requirements for the round was to shoot both super and subsonic rounds (specifically without any gas system adjustments). Some other requirements were that it had to work in STANAG mags in an AR patterned rifle, which knocked out the 7.62x39 as a contender.

[@joshrandall3632]

@@JabariHunt No, the Whisper was renamed in '09 so it could be made commercially available. The designer never had any aspirations of competing with the x39, for "supers" or otherwise.

With subsonic rounds, it duplicates the .45 ACP, but from a heavier, bulkier package. Hope this helps.

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.

[@edwardoavila7666]

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.

I was lead to believe that .300blk was the end-all-be-all for 5.56 alternatives. All the years of R&D only to arrive at something the Soviets figured out almost 80 years ago. I guess if you are looking for something that can be sub-sonic and use a suppressor, but that's a pretty niche market.

Ok round. Designed for 8 in barrels and subsonic. Check out 6arc, 6.5grendal, and 450 bushmaster. And now for varmints and target shooting new 22 arc.

[@danya822]

You have to really look at the short barrel performance as part of that niche. Otherwise in longer barrels (around 10.5") all the competing rounds (Arc, Grendel, Ham'r, etc.) /other calibers offer more performance when it comes to supersonic loads. For short barrels though, it's pretty hard to beat the versatility of the blackout.

[@EvilWiffles]

Yeah, the Soviets... If we are completely ignoring 7.92×33mm Kurz, which 7.62x39 is essentially a copy of. I guess the Soviets really didn't figure it out, since, ya know, they pretty much cloned 5.56 with their 5.45x39.

[@UncleDon226]

@@EvilWiffles It's almost as if weapons evolve over time and their lineage can be traced back to older cartridges. But I get it, you want to flex your knowledge on the history of the intermediate cartridge. By your logic, the .308, which is an evolution of the 30-06, which is an evolution of the 30-03, is just a cloned 7.92x57 that Germany developed at the start of the 20th century.

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.

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

[@rickybobby5950]

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.

[@sw_tower8530]

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

[@shane35fowler]

​@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

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.

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...

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.

[@OleDirtyMacSanchez]

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.

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.

[@andrzejsobanski6752]

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.

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.

Ak beats 300 until you compare 8in barrel to 8in barrel. 300 shines in short setups and is versatile with ammo weight and velocity. It's cool but I have yet to use mine for any kind of hunting.

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.
