[@randyhymas9013]

The 300 Blackout was originally designed with a heavy, slow moving (subsonic) bullet, intended to be used with a suppressor. The purpose was to take out bad guys as quietly as possible. Not to penetrate steel plates.

[@thebarkingmouse]

Exactly. I have a 300 that I built a few years ago as a dedicated suppressor host, and it is absolutely great for my planned use. Lethally accurate to over 100m, it is primarily a pig gun. Generally I can get three or four at a pop because they simply don't know which direction to run. If I wanted a light armor piercing weapon, then I would have gone a different direction. I've never seen a pig wearing armor plates.

It's also worth noting that the 7.62x39 ammo is a copper plated mild steel jacket and the 300 is an all copper jacket. That also gave it a significant advantage

[@jamesbridges7750]

This! It's as much about bullet construction as it is external ballistics- jacket material, jacket thickness, core hardness..... Old Chinese mild steel core will absolutely punch that 3/8 plate and some of the bimetal/copper wash will out of and SKS/ RPK. So if you find any yellow box x39 laying around it's worth picking up.

So youre upset that the absolute cheapest 7.62x39 penetrates way better, interesting, ok

[@nolanwalmsley4216]

@@AthelstanKing I'm not upset, just saying that it would be more fair to test similarly constructed bullets. It would be like comparing a 9mm with a hardened steel core to a cast lead .223, and when that particular 9mm outperforms .223 at armor penetration, saying 9mm is the better choice. Don't get me wrong, 7.62x39 with identical jacket construction would likely still come out on top as it has a slight edge on power, but it would probably be a pretty minimal difference. It's also worth noting that bi-metal jackets are typically seen as undesirable since they cause much more barrel wear and many indoor ranges and outdoor ranges with steel targets don't allow them

I'm not sure, but wasn't 300 AAC developed as a subsonic for CQB and not for armor plate?

[@LikePhoenixFromAshes]

Yup, and neither of those calibers were designed to penetrate hard armour plates. Not dissing on this video, it is fairly good, but terminal performance of those calibers in real scenarios on real tissues are vastly different. Then, both calibers are very good, especially when we are talking about more modern 7,62x39 bullet designs. Both are perfectly sufficient to hit human targets on up to 300m/yards and penetrate several layers of cloth and the expand in the body. I don't really get this fascination with steel penetration, unless one is unloading on medium-skinned vechicle (such as unarmoured Humvees, trucks etc.; vechicles more armoured than civilian pickup truck and less than standard M113) penetration is absolutely irrelevant. Both calibers are perfectly fine perforating cars and windshields, as many real life shootouts have proven already.

I would have to look it up, but I believe the Blackout will actually have an increased muzzle velocity with this length of barrel vs a 7.5 or 10 .5. He could have crippled both cartridges by firing them out of a two-inch barrel but what exactly would that prove? This wasn't a test designed to see which cartridge works best with shorter barrels.

One thing that you did not mention was the construction of the 7.62x39 bullet. Some eastern block ammunition has a steel core, which might dramatically affect its ability to penetrate a hard barrier/steel. I have no personal experience with the tool ammunition that you were using so I don’t know, but it would be worthwhile clarifying that point.

[@riccochet704]

Good luck finding steel core 7.62x39 in the U.S. since it has been banned from import since 1994. What you might be referring to is mildly magnetic cupronickel jacketing. They are lead core with a copper/nickel alloy jacketing that is mildly magnetic. The jacketing is about 5 ROH's harder than straight copper jacketing, which is rather insignificant. You'll find this on Wolf, Tula, Barnaul, Silver Bear and any other Russian / eastern comblock ammo. The only steel core, as far as I know, that was ever imported is Norinco from China. Which as I mentioned hasn't been imported since 1994. Rarely will you find a box at a gun show or pawn shop. It's the whole reason indoor ranges don't allow steel cased ammo. Which made sense in the late 80's to mid 90's. Not so much anymore, yet they still stick with that antiquated rule.

I can tell you that unless something has changed in the last three years, TulAmmo has a copper washed steel jacketed bullet.

The 300 AAC BLK supersonic might be seen as a 30 US Carbine cartridge on steroids. Actually, supersonic loads are suitable for CQB and out to ~ 300 yards. They also deliver enough power as a 100 yard white tail & brush country hog cartridge. The 300 BLK has superior self-defense stopping power over the .223/5.56 loads. There are a number of premier loads for this purpose. One that shines is the Hornady Black load in 110 gr. A-Max; it expands and penetrates well (discounting steel targets which don't tell much about performance in living tissue). One of the best things about the 300 BLK is its short barrel performance. The cartridge delivers a muzzle energy from 8 - 10" barrels equaling the 5.56 from a 16" barrel.

I think the "almost identical in performance" claim is mostly meant when comparing the subsonic cartridges. Typical 300 Blackout subsonic bullet weight is 200-220 grain, and typical x39 subsonic is 190-200 grain. And we can pretty safely assume they're both travelling the same speed, and they're the same diameter, so if they're close to the same mass they'll perform similarly. I would like to see if Hornady's fairly new 255 grain bullet gives x39 some additional oomph, especially since 8.6 Blackout has shown itself to be so, so much better than 300. Anyway, nice video, as always. Thanks for the upload.

Incorrect there Stumpy. The bullets and ammo selection is far greater and more available with .300aac , so there are lots of good subsonic or supersonic options for that cartage. 7.62x39 is slightly fatter, with a little more powder.

I worked at a full-service gun shop all through the '90s. We had some customers coming and telling us that a popular shooting area out in the National Forest had a recent restriction on shooting any firearms that fired 7.62x39 mm due to a claim that fires were being started when the rounds struck specific items and cause sparks. Our gunsmith out of curiosity, pulled a bullet out of one of the Norinco manufactured rounds that were common at that time, and he melted the lead out of the jacket, and came walking out and showed us that sure enough, the jacket of that bullet stuck to a magnet. Even though it appeared to be a copper jacket. It had enough steel in it to where it's stuck fairly well, not as solidly as if it had been all steel but I wouldn't have expected it to stick ar all, because the assumption was that was a copper jacket.

[@22leggedsasquatch]

The .300 blk is really a phenomenal round sub sonic and suppressed against'soft' targets. It's ballistics with a VERY short barrel are It's big selling point. It's Purpose Of Use is very different to the 7.62..

[@hawkuser604]

One round that I was impressed with was the 243 Winchester when it came to going through steel. Even with a soft point hunting bullet at 80 grains or even the 100 gr with the speed of around 3000 fps it had no issue punching through mild steel. I am sure rounds like the 25-06 would be similar. I couldn't imagine what a steel core 243 or 25-06 would do if they were made. I used to shoot old steel plates that the railroad used to leave behind after repairs with my 243. even with them hanging off a tree limb it would drill right through them at short range, but my buddy's 35 Remington would just leave a pock mark and a nice loud ring!! Velocity kills steel.

Yeah, found that out the hard way with 17HMR and my poor .22 spinner target. Buddies 17HMR, I had never shot one. Looked at the bullets and figured what can that pathetic little thing do. It drilled 3 holes in the spinner target before I realized it.

[@hawkuser604]

@@mrbyamile6973 I think, in my opinion, that we keep trying to reinvent the wheel when it comes to rifle cartridges. Anything being created today has already been done. All it does is create a shortage for the old standard cartridges. I know some of the purpose built rounds have their place, but most people that shoot them are going to end up hand loading anyway. I hand loaded for my 243 and got amazing results out of a factory built rifle back in the 1980's. 3/4 inch groups at 100 yards was about twice as good as factory loads. There is really no need for most of these new calibers. Have fun shooting!!!

[@andrewclodfelter3782]

I don't hunt steel plates with my supersonic 300 blackout rounds but I do hunt deer, coyotes, and bobcats. Ive never had any of them move after shooting them with 110 grain rounds. I took a large coyote wolf hybrid to a taxidermist after shooting it with a 300 blackout hornady Vmax and he asked me what I shot it with. He was shocked when I told him a 300 blackout. The bullet entered through the jaw bone went through the neck and into the body from an above angle shot and exploded inside. When he was skinning it he said the entire center was liquid mush. He thought it was hit with a much larger cartridge. Some benefits to having a 300 BO vs 7.62x39 is the ammo selection is superior. Most of the better bullets are 110 grains or less to make use of higher velocities. Also when shooting sub sonic it is reliable vs shooting supers with x39 then going to sub sonic ammo. You just don't get the same experience.

[@kalidilerious]

hmmm cool story bro. So he saw all that but didn't just look at the bullet that he took out? okay.

[@BuckeyeBallistics]

Aside from the obvious slightly higher velocity of the 7.62x39, that Russian steel cased ammo has a bi-metal alloy jacket on the bullet, which is much harder than the all copper jacket on the brass cased .300blk ammo. The harder jacket is going to help astronomically for penetrating steel. Use brass cased x39 with an equally soft jacket and then it's a fair comparison...

You used Barnes 125 gr hollow point in 300 blackout but 122 gr FMJ in 7.62?? Is that really a fair comparison considering one is designed for expansion (Barnes) and the other for penetration (FMJ)

[@westchester1R]

Barnes 120 grain hp is absolutely not designed to go through steel. And in my experience, 147-150 grain FMJ are not optimal for 300 Blackout either, 110 or 125 grain is a better supersonic round. You also say 300 Blackout was "designed" for subsonic rounds. I always thought it was designed to be able to shoot both supersonic and subsonic while keeping most of the same parts as a 5.56 AR. That's not exactly the same thing.

Reconfigure the test utilizing as fast of a round as possible in the .300blk. Try the 110gr v-max or something else similar in weight. With proper loading, you can reach almost 2500 fps.

@@compted10 no, it's velocity. You can easily push a 130gr solid copper bullet through 1/4" steel if it's going fast enough, say from a 308. Testing as was done here is inaccurate to say the least. Different bullets, different performance envelopes, and most importantly, different velocities. The round used for the 300 in this test is unquestionably at the bottom of performance in terms of what the blackout can do.

[@compted10]

@Dan Ya I don't disagree with your statement, but my point was that those projectiles acted like the typical match bullet. Where they break up on impact with steel to minimize target damage. Copper bullets tend to be decently hard aiding in my theory. I believe the 147 grain fmj could have been more comparable in mass retention to the 7.62x39 but was too heavy for the cartridge to develop comparable velocity. It's not just a velocity equation when dealing with hard targets. Velocity is important, but the projectile needs to stay intact mass wise as well.

[@danya822]

@@compted10 that WAS a solid copper bullet. It's going too slow to be effective. And since Barnes makes the 110 and 120 specifically to expand at Blackout velocities, it stands to reason it will perform poorly against hard objects.

M43 has a soft iron core swaged onto a soft iron jacket, and it has no more penetration than a comparable copper jacketed lead bullet: kzbin.info/www/bejne/fGObf35ros1_pdU They use super soft iron to cut cost, not to influence penetration behavior in any way.

I think you're thinking of new manufactured ammo, I'm talking about m43 spec bullets. the original m43 spec uses a mild steel core, and yes, you are right it wasn't purposely used for penetration. It was so it was cheaper to make, but the steel core actually aided the round to penetrate a lot more than the new wolf and tula stuff that's so common now. I don't think it's worth the price people ask for it I wouldn't pay a 1$ around for it but some people swear by it that's what some of the old norinco Chinese ammo boxes were and the old Russian ammo that's so hard to find because they declared it as armor piercing

There are even videos about this. The same goes for the rest of the Eastern European surplus, including Soviet. It is all made to the same specs, and it doesn't have special penetration.

300 blackout is for one purpose. Close quarter engagement. Close up, nato standard and ak rounds can go strait through a target, and the target will keep shooting. They don’t stop someone for shooting back unless you really hit something vital. Blackouts up to 250 meters will knock the target on their ass. It’s like getting hot with a sledgehammer. Because it doesn’t push through, more of its inertia transfers. Also, It has zero muzzle drop in its designated range. The people how developed them actively used them in combat, and this round is preferred by top tear operators, but it’s only for clearing buildings and or streets. Not for range or open field engagements. Use it for what it was made for… shooting other people in urban settings and you will understand what the fuss is. Compared to a 556. It has a much greater capacity to neutralize a threat. It isn’t design to penetrate armor. It’s designed to provide enough blunt force teams that an armor wearing opponent won’t be able to take a round and keep firing back at you.😊

This is great information; if I ever find myself going up against a hostile individual wearing body armor. But damn near ALL of the other videos out there, doing ballistics tests w/ the various 300blk rounds (from sub, to supersonic), show that the increased mass, combined with a lower velocity, means more of the terminal energy gets transferred to the intended target, while also resulting in significantly reduced instances of overpenetration, which, if I'm using mine inside my house, during a home invasion, I want to put as much energy into the invaders, while not having to worry (as much) about sending rounds into my neighbors' houses, or down the street. And circling back to the armored hostiles; even if the round doesn't penetrate the armor, it still has a high likelihood of taking the individual out of the fight, by pure virtue of the energy being transferred into their body.

However, expecting it to penetrate hard targets is like expecting the 5.56 round to be ideal for taking down large game just because it's fast. This ain't no military round, it's a down home bush-gun kinda round.

I think when people say that they are similar, it is because their external ballistics are somewhat comparable, However their terminal ballistics can vary quit a bit. Another factor I don't think I saw here... Most if not all the 300 BO bullets are true lead/ copper jacketed and most military 7.62 x 39 bullets on the market are "Bi-metal" with some steel mixed into the makeup of the bullet. That's why many 7.62 rounds don't pass the 'Magnet test" at ranges that don't allow steel bullets like the 5.56 M855 Green tips. The addition of steel may account for the better hard target penetration. That said, the 300 BO is a specialized round for specialized purposes and is not necessarily comparable to a battle field round so it's a little like comparing apples to oranges in terms of terminal ballistics.

The Barnes bullet is an all copper hollow point. The Tula ammo uses a copper washed steel jacket over a lead/tin core. 250 to 300 feet per second could be the second factor. I shot case after case of Chinese steel core 762x39 in the 80s and 90s. It was about $80 for the 1000rnd case and $90 for the 1200rnd case. Sometimes the jacket would shed and just "squirt" the steel core through steel scrap or cast iron. This is where your shooting shield could come in handy. An old friend of ours got to close to a steel plate and the jacket bounced back and imbedded itself in his belly. Luckily he was a pretty fat guy and the doctor pulled it out and stitched him up without complications.
