What furniture is that?

>>34412166
Not entirely sure.
This is a picture from my folder when I was looking for specs and reviews from IO hellhound AKs (which are highly pre-disposed to unexplainable corrosion)

556 = better performance at range and you will likely kill your target in one shot if your aim for their vitals is true.
The tumbling is beneficial as well, but idk how often that happens. Depends on barrel twist, load, grains etc...
7.62x39 = superior penetration and violence at close range + death from hydrostatic shock (look it up, its pretty narly).

As much as I love the M43 round and the combloc weapons that shoot it, I believe that 556 offers more options and better lethality in both symetric and asymetric warfare.

If you are asking what I'd shoot somebody with to guarantee their death? 7.62x39 but it must be under ideal battlefield conditions (which are more narrow than the 556).

>>34412148
5.56.
It was so good the Russians copied it.

Interesting.
Im surprised you would say that conditions are more narrow for a 7.62. I would have expected the 556 because even a piece of fucking grass can deflect those flimsy fuckers.

Specifically wondering about long range as well, around 200 yards. Nothing scares me more than if you were to shoot something and it either wanders off, or goes into hiding mode waiting to return the favor to you.

7.62 really only loses most of its effectiveness against soft targets at 300m and quickly becomes useless at 450. Inside of that, its quite lethal.

I know the 762 is capable, which is why its such a beautiful round. but what about 556?

Years ago I bought my AR, and the more I search, the more it feels like there is an utter lack of data for this platform in that area. It terrifies me that my main rifle could be a defective war novelty.

Humans don't fair very well with holes poked into them. The appropriateness of a cartridge depends on the distance you want to be from them when the hole is made.

Velocity (to cover more distance before gravity pulls the projectile into the ground) and bullet shape (to overcome the friction inherent in traveling at high-speed through fluid) govern the effective distance you can poke holes through a person.

Most everything else is fuddlore/mallninjalore and personal opinions.

Like I said, im wondering what happens if you get a single shot on someone, around 200 yards. Which cartidge is going to do more damage and put them down faster.

Nothing scarier than if the thung your hunting is injured and goes into hiding mode waiting for you to come back out. 556 being so small makes me wonder about this.

>An 8-month study in Iraq performed in 2010 and published in 2011 reports on autopsies of 30 gunshot victims struck with high-velocity (greater than 2500 fps) rifle bullets.[25] In all 30 cases, autopsies revealed injuries distant from the main wound channel due to hydrostatic shock. >The authors determined that the lungs and chest are the most susceptible to distant wounding, followed by the abdomen. The authors conclude:

>Distant injuries away from the main track in high velocity missile injuries are very important and almost always present in all cases especially in the chest and abdomen and this should be put in the consideration on the part of the forensic pathologist and probably the general surgeon

>>34412704
You drop a human by putting a hole in the CNS or heart. That's a matter governed mostly by shooter skill. Most popular cartridges have their loadings figured out for repeatable ballistics. There's something to be said for variation based on quality of the firearm used, but for simplicity, we'll just assume mechanical equivalency.

In a practical context, you want to one-shot someone? Sneak up on them and put a bullet in their head from as close as you can. If you can't make that shot? Put as many holes in them wherever you can.

Even if it ends up being a wounding shot, 7.62x39 has a better chance of incapacitating your foe. Even armored foes will get knocked down harder and plausibly get internal bleeding and wounds to vitals more often with the M43s.

Within 200 meters, definately the 7.62x39.

Probably why 95 US Marines were killed in the Battle of Fallujah 2004, and virtually no one dies from an AK in Afghanistan because the snakbars are shooting from 600+ meters atop a mountain.

>>34412658
The main advantage 5.56 has over 7.62x39 is longer effective range and a better ability to penetrate hard targets. So I mean, unless you're fighting guys with body armor 500 yards away, 7.62x39 is going to work just fine.

Hydrostatic shock is literally "stopping power" it's bullshit and I'll tell you why.
If you did some reading, and read material that was written by SME's like Dr. Fackler, and by other trauma surgeons.

There are ONLY two ways to incapacitate a human. One, is by destruction of the Central Nervous System, aka your brain.
The other is by loss of blood to the point where the body can't supply the brain with oxygen, again CNS.

>>34412786
if that were really the case, people would explode from kicks to the chest.

>>34412913
I didn't say HS was the be-all, end-all of projectile effectiveness (it certainly adds something though).
7.62x39 hits harder, makes bigger holes, and penetrates more light cover than 556. These are its main advantages that I thought I had explained well >>34412505 and
>>34412899
>ONLY two ways
Are you saying that fucking up somebody's lungs or legs wont incapacitate them? Even with minimal bloodloss, people can go into shock. Large enough rounds might even break your spine if you're hit on the back plate.

>>34412982
>Large enough rounds might even break your spine if you're hit on the back plate.

Do we really need to explain basic physics to you?

>>34412961
Maybe if those kicks were at 2500fps and travelled through the chest cavity

the real answer is 5.45x39

5.56 is the round of freedom. When you fire it, 100's of years of patriot spirit are encapsulated in your round, and as it flies straight and true towards its target, the enemy, only too late, sees the error of his ways. Communists, warlord thugs, and terrorists alike have all tasted the sweet, refreshing tang of freedom as they breathed their last breath. It's almost a shame that the glorious democratic rounds that tumble through each of these foes can't be used again. They are the American dream.

>>34413096
ar15s are boring though, they have no soul.

>>34413102
Intermediate cartridges are like the hors d'oeuvres of firearm chamberings.

>>34412148
its all about shot placement
if you hit someone in the arm with either it isn't going to do much but hit anyone in the heart and you'll pretty much kill them every time
I would probably say softnose 7.62 for wound cavity though
hollowpoint 5.56 isn't much worse though

there is no answer

This is the true answer.

With quality ammunition, you will literally never be able to tell the difference in terminal performance. They both work very well.

99% of the stories of "muh 5.56 didn't kill him and I shot 15 times!" are bullshit made up by people that can't admit they can't shoot, and didn't hit the person they were trying to kill. Yes, that includes whatever "operator" you chose to dick suck.

>>34413018
nah man, foot-pound force. Very comparable.

>>34412148
5.56 comes in a bunch of really effective flavors. The stuff you buy in bulk, usually xm193 or xm855, are not included in that selection.

7.62x39 has 8m3.

Pretty much all 5.45x39 will tumble reliably.

You can carry more 5.56 into battle than 7.62, its better to wound enemies than to kill ought right (puts a strain on oppositions resources).
It takes 2 men to carry or care for 1 wounded man.

>>34412148
Both suck except for 556 with the new m855a1.
I'd like to see a really high ballistic coefficient(greater than .5) 6.5mm cartridge weighing 140 grains or maybe 150 with 60 to 70 grain hardened steel penetrator tip going at 2700 fps in an ar15 from a 18 inch barrel and maybe a modified one with a bigger bolt head for bigger lugs or perhaps a four lug design. Also have the bullet have an air pocket or something so that it will tumble when it hits something like flesh. The other half of the bullet(half of the weight) should be pure soft lead. Also the jacket should be harder. Gliding material is like 30 to 40 brinell, on this one it should be 60 to 80 for better accuracy. Capacity would be 25. Much higher pressures than a 6.5 Grendel.

Would have amazing range and would be amazing for close combat. Would have stellar armor penetration as well at any range.
You could even have a smaller sized bullet with just a hardened steel core, say at 70 grains traveling at 3100 fps for armor penetration or perhaps 90 grains but tungsten carbide. Maybe even just pure lead but with a hardened steel jacket followed by a normal copper jacket and a small 10 grain tungsten carbide penetrator tip.

Wow! I guess his body couldn't provide oxygenated blood to his brain right! Guess who uses "Hydrostatic shock" to measure ballistic trauma? NOBODY. If we did you'd just shoot jugs of water to see how far they sprayed.

Oh shut up, that comment made me fuckin laugh.

>>34413394
Fuck that shit. If im going to shoot at something I want it D-E-AD.

This wounding horse shit is what scares the living fuck out of me. I dont want whatever I shot running into the bushes and waiting for me to pop out so he can return the lead.

I also have heard that when a 556 hits someone, it almost "pops" and suddenly the body loses all blood pressure, so they essentially drop.. Anyone know anything about this?
