5.56 vs 5.45x39 On Mild Steel: NOT So Similar After All? 

That makes sense. I bet that was the info that I was reading and didn’t realize that there was a difference in designation

@@bananaballistics - You have a troll using your site for scamming purposes. Under my name in the comments.

I have some im selling on gunbroker

@@bananaballistics They are often non distinguished in designation just like 7N10 and 7N10M , 7n24 and 7N24M and 7.62x39 PS and 7.62x39 PSM

knowing russia, even if it was supposed to be a hardened steel core, it probably wasnt. but also i thought the purpose of that round was moreso to tumble then penetrate.

It also makes bullet very unstable after hit

7n6 is not AP at all

It also allows the bullet to be lighter for length

Can't imagine why it would be cheaper. Lead is cheaper than steel

@@theimmortal4718 In Soviet Russia, steel is cheaper than lead ;-)

lol russia sucks

Kills by tumbling inside a human target?

@@adrianrubi5012 Penetrating 5-7 cm into the soft body, it begins to tumble there

@@adrianrubi5012as does the 5.56.. Tumble and fragment kinda at the same time.

@@goldenremnant2610 no wonder Reid Heinrichs zeroes them in the same manner he kinda said they were ballistic twins.

Daže 7n6m uže hotj skoljko-to probivnaâ. Molča o 7n10. I têm bolêê o 7n22 i 7n24

7h39

And 7n6m aswell

So as too M855 is the same that russian one

@@user-vz2wb8hm5g now there is 7n39 with a tungsten rod

7n6 is light bullet that's substantially lighter than lead FMJ. Research the material part before typing your fancy, and really-really convenient QWERTY keyboard, dorogoj inostranêc.

I guess you missed the cheese sprinkled liberally throughout the video.

It was discovered with steel core ammo like 7N6 that when the jacket stays inside the bullet hole, it slows down the core passing through it. Some later version of 5.45x39 ammo were optimized for penetrating steel and aluminum. They use a hardened and more pointed core with.a little lead between the tip of the penetrator and the nose of the jacket. The lead's job is to split the jacket at the front so the penetrator can go through the barrier (steel or aluminum) without dragging the jacket through the hole.

Hello from America i though u swedes were aloud to own guns?

Sure, they're just not very common here =)@@trackpackgt877

@@trackpackgt877 They are!Also they still have conscription,so this posting is not logical.--He could have done alternative"Civil-service" or be unfit for service!

@@pe.bo.5038 oh ok thanks for the info brother i thought sweeds had to serve in their military and were required to own a rifle seen a documentary on it so u may be right about him ☝️

​@trackpackgt877 That's not the Swedes. Sweeden has extremely strict gun control. You're thinking about the Swiss as in Switzerland. They have more lax gun laws and everyone serves in the military

That’s awesome 😎

.303 or .30-06🤔???????How would.303 AP get to the US;except you are Canadian???

@@pe.bo.5038 You realize. 303 ammo is available on every continent on this earth right? You realize every ammo manufacturer in the US produced ammo for the .303 and many still do? Educate yourself, if thats not possible try google ffs.

@@panthermartin7784 🤡Dummy!I don't need your stupid lecture at all!-No,there for sure is no production of .303 AP in the US!-Not now;not in WW2In fact the ATF will take great interest in you,if you have these in your possession!🤢🤮

Bingo and I can't believe I have never thought about doing this test since I have so much scrap steel laying around outside my shop

The Soviet round uses a mild steel core and is not intended to be an armour piercing round. They (Soviets) have specific armour piercing rounds with hardened steel cores, but their ball rounds often have mild steel cores instead of lead.

exactly. Cartridge 223 is a copy of the sports 222, 5.45, a product of high engineering.

5.56 can shot heavyer bullet so it have a better bc and most 5.45 have a steel core to penetrate stuff when 5.56 dont it is not about the caliber but the bullet type

And i just finished wacht t he video the 5.56 did pen more in is testing lol

@@user-db8mz6lt6g hight enginering that do everything worts that 5.56 expect recoil thats funny

@@TheJimyyy justify your comment

Which 5.56? The original 55gr out of the 1in12 twist Or the 62 steel penetrator out of the 1in7?

I agree! Lol 🔫

Where can one acquire some?

Gunbroker I have acquired about 400 rounds

M855A1 out of my 20 inch barrel chrono 3268 fps and put a hole in my 3/8 ar500 target at 40 ish yards

Yes

Best thing was the cheap price…. Its corrosive though? So wouldnt touch it with my guns

7n6 has superior wounding mechanism and terminal ballistics to 5.56 over the entire flight path. It's a higher BC bullet with greater sectional density.

@@BigSmartArmed i meant over 5,45ball from tula

@@manganvbg90 While it was around it was the cheapest and the most accurate 5.45.

@@BigSmartArmed yes but corrosive and im lazy 😁

You do realize that 60hrc is how hard knives are…. That’s not annealed.

That red band denotes normal 7n6. Where do you get your information?

All military ammo is sealed.

Send him your ammo

I’ll have to look into that one

7n10 is super rare in the US

18.6 inch barrel in canadia goes brrrrrrr

I wasn’t aware of an M designation, but that would explain it

Energy transfer is far greater when the target is solidly mounted. Live combat always demonstrates that fact. That 243 definitely has the velocity advantage.

@@johnmcclain3887 that plus a very slim profile. Biggest issue i saw in that video i mentioned was that he didnt even wait out the time to let the plate stabilize again. Thats why i like this channel here same parameters for every round fired

@@julianeder4699 I suspect we find ourselves on many the same channels, I've been retired just since this plandemic, and too much time on my hands. They killed my machine shop.

There's also the factor of the plate able to move, and substantial force transferred in plate movement rather than moving the metal in the discrete striking zone.

@@johnmcclain3887 Wouldnt surprise me once one starts goin down the firearms rabbithole on youtube its only a question of time till you see a collab between a big guntuber with a smaller channel or another video on a certain type of round. Think my journey started back in the FPS Russia/ early Demo ranch days but just like in your case the pandemic inevitably lead to a bunch of boredom and a reinvigoration of my interrest in firearms especially since guns are a rather sensitive topic in my country of origin. As for the bullet striking the plate and the latter giving way to the impact via means of bein pushed backwards instead of letting the projectile pass through i sadly dont really understand how much it effects the performance of a round as most slow mo cameras on youtube slow down time only to a max of a 10th of the real life speed which is nowhere near enough to draw reliable conclusions on the subject. Ive seen a ton of comments on the subject especially on the channel goin ballistic aswell as theories on how spacing the plates apart could alter the outcome significantly but most of them just threw a bunch of numbers arround that my brain simply couldnt comprehend. That bein said the more randomn parameters one can eliminate in their testing environment the more clear cut the results get and the immobile nature of mr bananas setup, him settin up the plates at a 90° angle aswell as the grinding and precise measurements bein done afterwards most definitely eliminate a lot of the factors that could make a rounds performance deviate from the norm. Oh and enjoy the pleasures of retirement ive still got myself a good 3-4 decades before i can hang up my boots

It does seem to have a large air pocket

That pocket does nothing on steel. Its purpose is to make the projectile more butt heavy so it tumbles quicker in soft tissue.

​@@eloiseharbeson2483That was my point.....

Hopefully I can test both sometime in the future
