Run the test at 200 yards and the results will be different 7.62x39 sheeds energy while travelin down range. That is why is has such poor down range balistics. 5.56 will penitrate more at distance and still have more energy on target. Plus the round is more accurate, deflects wind better and has less drop leading to more accurate shooting on target at range.
I'm guessing you failed physics kid LOL
more accurate and flatter shooting yes
more penetration NOOOOOOOOOOOOO
A thirty cal slug from an AK can kill a man stone dead at 1000 yards if you could somehow hit someone that far away. A a 5.56 won't even penetrate a road sign at that distance.

That's funny because 7.62x39 will be subsonic around 500 yards and will loose the very little accuracy it has as it tumbles towards the target. A standard 5.56 load will stay supersonic past 800 yards while some specialty loads are shot accurately at 1k yards. Take a look at high power service rifle matches.

We weren't talking about accuracy, we were discussing penetration.
Fact........A 5.56MM has less power than a .22lr at 900 yards
fact .......A 7.62x39 will still penetrate a steel GI helmet at 1000 yards. A 5.56 won't.
fact .......a 7.62x39 is traveling at the same velocity as a 5.56 at 1000 yards, which is around 700-800 FPS.
fact .......the united states military lists the effective combat range of the 5.56 at 300 yards.
and if you want to talk specialty loads, they make 7.62x39 loads that compare to a low ball .308

WOW how interesting. A link describing exactly what I've already said 3 times.
[Mod cut] We weren't talking about accuracy, we were discussing penetration.
All of my facts are correct. You seem to think that I'm talking bad about AR's or the 5.56, but I'm not; I like AR's. I think they're great rifles, and I like the .223 round, but to say that it will out penetrate a 7.62x39 at any range is simply not true.
And for the record, the soviets switched to the 5.45 for the same reason we switched to the 5.56.
It had nothing to do with the performance of the round.

Reason: This is not 3rd grade.
Boy, are you WRONG about 223 at 1000 yds. The modern VLD bullets still hit harder at 1000 yds than the .38lrn from a snubby hits at 10 ft of range. The 62 gr military stuff still has more power left out there than a .22lr pistol has at the muzzle, too. that's still quite lethal. Not that it matters any. nobody hits anything in rifle combat, with iron sighted autoloaders, beyond 1/4 mile, except by pure luck.

How am I wrong?
nothing I've said is nonfactual, and if you can prove otherwise I will gladly admit that I'm wrong
your comparing specialized ammo from a rifle to pistols. That's not apples to apples.
check this out...........a .223 out of a 2" barrel at 200 yards is less powerful than a 380 auto ....see what I did there
fact ......a 22 rifle point blank hits harder than standard .223 ball ammo does at 900 yards.
If you would like to test that theory try shooting a stop sign from 900 yards with a bolt action .223 varmint riffle, and then shoot it with a ruger 10/22 point blank with junk ammo.
I never said it wasn't lethal either. I just said it doesn't penetrate as well as 7.62x39 does at any range.
[SIZE=3]AR- a situational tool which requires frequent cleaning, and disassembly. Very accurate and customizable. Prone to jamming if not properly cared for. [/SIZE]
[SIZE=3]AK-very reliable tool that requires minimal maintenance. Cleaning, maintenance instructions- “when bolt rusts shut, drink large amounts of vodka and urinate on the bolt and kick open” then you good to go[/SIZE]
not, it's not. lethal is lethal. I am pointing out to you that the 223 is lethal at 1000 yds, if it's loaded right. you are quite mistaken to say that it's a joke at that range. it's not.
7.62x39 is a under powered round and lacks penetration and any sort of ranged accuracy.
AK work well, but because they have very loose tollorence they have very poor accuracy.
The 7.62x39 is roughly as powerful as the .30-30 Winchester. The 5.56x45 NATO is the military version of the .223 Remington. A hunter would consider the two to be in completely different classes- the .223 is a long-range varmint rifle while the .30-30 is a moderate-range deer/pig rifle.
The penetration of the 5.56 is better than the 7.62x39 because the current 5.56 rounds have a very high sectional density- the current military load is over 70 grains IIRC. The standard load for the 7.62 is 123 grains which is a very short bullet for a .30-caliber rifle, short enough to shoot poorly in most other .30-caliber rifles like the .308/7.62x51 with a typical 1:10 twist rate optimized for 150-180 grain bullets.
The biggest reason accuracy "sucks" in AKs is because most Americans shoot the wrong diameter bullets through them. The 7.62x39 officially uses the British 7.62 mm .303 caliber/.311 diameter rather than the American 7.62 mm (7.62x51 mm/.308 Win and 7.62x62 mm/.30-06) .300 caliber/.308 diameter. Nearly all American-made and available 7.62x29 ammunition uses the .308 diameter bullets used in other .30-caliber rounds rather than the proper .311 diameter bullets. Yet the AK clones we see here are nearly all .303 caliber barrels lest somebody get ahold of some .311 diameter surplus ammo from East Buttcrackistan and blow up a .300 caliber barrel due to the excess pressure of trying to swage a bullet down 0.003" in the barrel. Also, it's perfectly safe to shoot a .308 diameter bullet down a .303 caliber barrel, accuracy just sucks. The U.S. ammo makers also widely use the same 125 grain .308 bullets they use in 7.62x39 loads in low-recoil .308 and .30-06 rounds. What else in the U.S. would use a .311 diameter bullet? The .303 British is about it, which is extremely uncommon in the U.S. as the contemporary .308 diameter .30-06 was our service round and also considerably more powerful to boot. Shoot, any .303 British rounds found here loaded domestically are probably also loaded with .308 diameter bullets as well! The guys I know that shoot AKs are very picky about their ammunition unless they are just plinking. There are a few domestic makers (Hornady comes to mind) that provide decent .310"/.311" bullets and rounds and that's what they use when they want to be accurate.
