5.45x39 vs 7.62x39: ANY Difference On Mild Steel? 

If those rounds are Russian commercial manufacture then they have no steel in the core. The magnet is sticking to the mild steel jackets.

The SKS in 7.62x39 entered service before the AK, and has a 20" barrel. Would be interesting to see if the longer length makes a difference.

You killed me when you put the graphic on the screen that said, I picked it up later that had me laughing my a** off!

If you had real 7N6, you had a mild steel core. The 7,62x39 was commercial and does not have a steel core. It has a bimetallic jacket. If you want 7.62x39 with a steel core, you need to find some of the old norinco ammunition. There was also a small batch of Russian M43 that sneaked in and maybe so old East German stuff that had steel core. Other than that, everything else isn’t steel core.

Only way to really tell what the bullet is made of is to take it apart. Sometimes there is a bi-metal jacket over a thin layer of lead over a mild steel core.

Really enjoying the content. Have you ever tested 77 grain 5.56? I’d be interested in seeing how it compares to rounds like the 6.5 Grendel or 6mm ARC.

I've bought a TON of stuff from Midway USA. Great folks.

None of those have a steel core. They use a bi-metallic jacket that's ferrous.

Dude bro you totally had me, I thought it was gonna be time to grind but then you were like noooo, and I was like whaaaa

Russian commercial ammo uses a bi-metal jacket. It's a steel jacket with a thin cooper jacket over it. Russian mil surp all have mild steel cores. Hence the magnet sticking.

i just recently started following your channel. love the quick to the point, no rambling approach. as some already said, i also think a table at the end to have an easier way to compare would be cool. i'm living in a country with firearm access to civillians, though not nearly as easy as in the states. shooting out in the open on a not specially certified range with all sorts of requirements like in your videos would be impossible here, so it's nice to see these tests, i can not do myself legally.

I still do wonder how the 5. 56 round SS109 would do compared to M855

Great videos , I like your content so much , I would love to see a steel penetration test between .204 Ruger vs .223 , it will be interesting. Many thanks

It would be interesting to show a table at the end for an easier comparison.

Yeah its their jackets that are magnetic they are just copper washed 🤣

Old exmilitary 7,62x39 have steel inside, BUT this is not armore piercing ammo. In Poland, USRR, and China factory used steel rod because it was cheaper than lead. Steel rod inside this projectals is very very soft.

Last time I was this fast my son was born. My favorite gun channel and the only channel I hit the Bell on. Thanks for the awesome content cheers from Canada 🍻

I think it’d be cool to maybe give away some of the plates in some way that have holes in them. They are like artwork pretty much if u ask me 🍌💥💨

I would choose 7.62x39 over 5.45x39 (and 5.56) for 1 simple reason: Combatants rarely stand in the open away from cover. 7.62x39 will carry an ass load of energy THROUGH a barrier better than the lighter, faster bullets thanks to its bullet mass. Sure, you can mitigate SOME of that with bullet construction being partially mild steel (M855 for example) but its not really that great a substitute for mass retention. Now, lets talk about their effective ranges. Most engagements are within 300 meters or so, which both rounds can effectively reach. If you really expect to engage targets outside 400-500 meters or more, perhaps you should consider a heavy hitter rifle in 7.62x51 or 7.62x54r. There's a reason the army and marines dusted off their old stocks of M14s to make DMRs.

Most Russian 5.45 and 7.62 use bi-metal jacketed bullets. Your magnet may be picking up that.

The bi metal jacket on those rounds may fake the magnet test. I had that issue with really similar look baurnaul ammo at the range. The range guy took a magnet to it. Turned out they sold it there so i was allowed to use it thankfuly (Edit mine was new ammo though. Not as cool as what you have there!)

you should get a better chronograph

Excellent video. ❤ Your channel is really growing. Keep up the great work. Very interesting subjects and rounds.

Its a bi-metal jacket not a steel core @ 3:50

The 5.45 was too "exotic" IMO. But I've really come to appreciate this round. 7N24 Tungsten Core pees on M855.

They are not steel core, its a steel jacket washed in copper, thats why the magnet sticks

I believe the " Steel core" is sintered metal... Powdered metal formed in a press under extreme pressure. Then its copper coated.

I feel like your graduations of plate thicknesses are too coarse. I've been binging all your videos because I just discovered your channel and love it and seems like pretty often I see two rounds perform differently penetrating the 1/4 then both are stopped by the 3/8. What if you started with a 6mm plate (slightly less than 1/4 in), then stepped it up 1 mm at a time until nothing penetrates? A lot more steel plate money but the data won't improve itself

A lot of cheap plate steel has impurities in it and can make it harder or softer as I've found when cutting it.

im curious if you stack the shots will subsequent shots penetrate the steel or will the first round work harden the steel and make it more difficult to penetrate?

“7.62x39 has the cleanest holes on 1/4” mild steel” it’s the “frustum” created by its ballistics 🔥🔥💯💯💯

You should have got a ton more ribbing for thinking those bi-metal jacket rounds had steel cores. 😊

Да любая баба скажет - чем толще, тем лучше! Так что зачем такие видео?

That 7.62 by 39 steel core ammo look exactly like some Chinese steel core ammo that I bought for my AK back in the early 2000s. Same color shell casing, and also had the thick red ring painted around the base of the bullet above the shell.

Oofta. Ar's shooting AK cartridges is a bad mix. Ak calibers require an excessively powered trigger spring to detonate those hard primers. I had a 5.45 AR with a hiperfire trigger, wolff increased power springs and an extra long firing pin and with 7n6 surplus I was running, at best, with 90% reliability. Never run russian milsurp in an AR. You're asking for failure.

Awesome video, as always. 👏 👏 👏

Ballistic twins would be like 5.56 and the 5.45x39 or the 7.62x39 and the 300BLK or 30-30. 😂😂😂

i have a dumb question: what would be the difference between the western 5.56mm and the russian 5.45mm rifle bullets? they are like clones right? logically 5.45 would be slightly smaller than the 5.56

nearly all 762x39 has a bimetal jacket, which sticks to magnets. doesnt mean its a steel core

First of all we're Americans so you're a kindergartener Since the 1980s you take the hollow point you you might have to drill a little bit to open up the hollow point might not you get a steel barren steel BB place it into the Hollywood pour super glue in And there is your armor-piercing Which I don't think they make 5.45 hollow point I know they do the 7.62

yeah i dont think that last 7.62x39 round was steel core i think it just had a bimetal jacket as did all the ammo u shot the jacket is copper/ steel. The old steel core stuff was chocolate colored Chinese norinco 7.62x39 I know because I've got a few rounds of it. Great video though always love your steel penetration tests

It looks like your 7.62 x 39 is a hollow point - I have steel core 7.62 x 39 steel core mil surplus ammo and it looks nothing like the ammo you used...

Those are bimetal jackets. Very soft steel coated with copper.

Mild steel core

@BananasBallistics try the 127gr 300 blackout Fiochi rated at 2200fps

I hate those sanding disks. I can see just by looking you went deeper than the parent steel. If that was a pipe or a pressure vessel you would be in trouble. Don't worry it's not your fault there are experience trademen that go too deep with those stupid sounding wheels because they think it looks shiny. But this is a cool video

I would of liked to have seen this with some 53gr 7N6 vs the 60gr commercial load.

You think you can test some hornady 5.45x39 vmax they have steel and brass I know where to get both

You need to start a podcast, that voice is made for it.

Why don’t you just paint the metal blanks in the metal holder/stand? No paint on the fingers that way 😊

Next video 408 cheytac vs 50 BMG,please👍

I am commenting because I think the ammo is special but only because it seem like it is. I had to look up the frame-by-frame controls so I could read that. Thank you for the great content, keep up the good work!

I do love your videos, thanks for making the information fun

Still, you're comparing mild, anti-personnel lead ammo, not AP.

Riverwie lovely Nood experience of Win Mag 300 gun on a plate 2 ml

Did thay black shell say "seven point FIVE two"???

I love how this long shooting video with talking are somehow my exception of shooting video. Your speech delivery is somewhat calm and to the point so that i don't get bored lol. Love this channel

To be 100 percent sure you need to pull one bullet and cut it in half to make sure it has a steel core...

Banana. Get some tungsten welding electrodes and cut em down to fit inside a hollowpoint.

@bananaballistics can you make 22tcm vs 5.7 against steel please

Need to inspect results when u shoot using the same assault rifles. Barrel length must be the same

Czech ammo with tungsten core is pretty good stuff.

Not necessarily a steel core bullet. The bullet jackets are copper plated steel. Saw a bullet in half to find out.

You just had some baurnals or the like hollow bi metal jackets

Seria interessante mostrar uma tabela no final para uma comparação mais fácil.

I bet the 7.62 make a clean hole is because it plugged it out.

i would like to see 76239 compared to3030

As many others have said those rounds don’t have a steel core they have a bimetal jacket. That’s why a lot of indoor and even some outdoor ranges don’t allow steel cased and other russin ammos. The jacket being harder can cause sparks which could result in a fire. That’s also why steel cased ammo will wear out a barrel faster. I think it was military arms channel that just did a video how they set their range on fire shooting steel cased ammo. that being said it would be interesting to see a round of wolf .223 up against a fmj .223 round as i have heard alot that the bi metal jacket will get slightly better penetration. Maybe pull some bullets from some wolf .223 and load up some spicy boy 5.56 loads and see how it compares to m193. Edit: about your chrono, i saw a guy using the same one and he had a bungee cord wrapped around it holding it on to a supressor to get it far enough out. I’d give that a try, 2-3 shots won’t get it hot enough to hurt anything.

Great video Brother, attention to detail and interesting calibers. I know that you have done the 6.5 Grendel before, but if someone made it with a steel penetrator, that would make a another nice addition! 😎

Love these comparison video , but I wonder would you want a penetrating round or a power dump round ?? Hard solid target or soft tissue target

Basic steel core 7.62 pens better than 5.45.

No chance for hunting ammo.

How fast in 7.62x51 NATO?

Is that your real voice? It’s like butta 🧈 😆

If Jim Breuer and Nick kroll had a baby

🇦🇺😎👍

How come never heard of this channel? Hidden Gem.. 338 lapua brought me here. but hope you make it MainStream--I subbed

Too much bullshit, just get to the data.

เสียงใหญ่เกินนาย ฟังแล้วแปลกๆ

Ya, the AKs not so much, but good test.

Unless there's an AP designation specific to the bullet you're firing, then you're going to have these 'mixed results' from shooting a medium the round wasn't meant to be used on. Infantry weapons are designed to fight infantry troops not armored vehicles. Mind blown, I know right?

🥇🥈🥉🏆👏👏👏🤗👮‍♂️🤠Excellent job thanks greetings from San Diego CA sincerely Jose Silva.

Do you enjoy your 5.45 AR? Do you need special magazines or do 5.56 mags work? My 7.62x39 AR required a stronger hammer spring and improved firing pin to work but I love it.

By the way I'm really liking the videos, just subbed :-)

I already lost this debate back in 2008 mr. Bananas please let me tell you that the 7.62 ammo is not steel core. Hard to believe because of how that magnet jumps at those rounds but trust me. Instead of a steel core it is a steel jacket that has been copper plated. This is done to further reduce the cost to produce the ammo and has little to zero bearing on accuracy, penetration, or from what I can see barrel longevity. I guess you will have to use a file to cut one down to show your audience. Cheers from Texas. and keep of the great work we love your channel.

Yes, all steel cased AK ammo uses steel jacketed bullets. Years ago, I found with 9mm ammo, raising the velocity does improve penetration.,

Steel jacket with copper wash not steel core, try pulling some bullets and cutting them with hacksaw. Since I'm in Canada we have lots of "real" surplus ammo with actual steel core. Correct me if I'm wrong but the US banned Chinese ammo imports a long time ago. I have at least 4 different varieties of true steel core com-bloc 7.62x39, most ranges won't let us use it due to ricochet and fire hazard from possible sparks on steel targets or rocks.

You should have used Chinese Norinco manufactured copper wash 762 x39 it does have a steel penetrator

I'm a VERY straight guy ... but have to admit you have one of the best voices in the content creator sphere! bwahahahaha

Wouldn’t that be a steel or a bimetal jacket, and not steel core? At least that’s what my Russian ammo is like.

No 7n6? How is this possible?

How about m855a1 out of a 20 inch barrel AR 🧐 or any 5.56 out of 20 inch

You should try the 220 swift and see how much steel it'll go through.. I heard it'll go through 1/2 inch steel

I’m disappointed in 5.45.

With the right ammunition the 7.62x39 can cut thru 3/4 inch of steel.

Very cool video 👍💪🔥💯

7,62 is older than the AK, so it wasn't designed to shoot from AK.

If you have an old microwave that you need to throw away, take it apart and remove the magnets, they are big and powerful. Mount them on the jig to hold the plate in place. Be careful not to touch a certain part in there because it has high voltage even turned off. It's very easy to remove the magnets.

Speedy talk and no table sheet preview is the real itch. Deep voice makes it just funny.
