5.56 vs 7.62

[leoffensive]

i posted this video earlier but was pulled off for language so i asked my friend to edit out the vulgar language and re upload it because it shows some interesting results

cmon now some of us are poor folk and cant afford ballistics jel. nah its actually pretty comparable to flash as far as consistency. btw thanks for embedding the video sir.

7.62x39 FTW, because shooting twice is just silly...

[bigbob76]

Even better, turn cover into concealment with 7.62x51.

Interesting, thanks for the quick info.

That was as unscientific a test as I've seen, though it's been replicated all over the net for years.

The condemnation of their "ballistic medium" notwithstanding, there is also a lack of specificity on such things as ammunition type being tested. Why is "7.62x39" sufficient but he felt compelled to refer to the 5.56x45 mm as "193" (M193 I presume?).

For an objective test identical weapons should be used chambered in each caliber and tested at various distances from a few meters to several hundred. Similarly constructed ammunition in each caliber should be utilized for the testing. Target angle is also a significant issue, rarely do targets present a full frontal silhouette and as some real-world trauma studies have shown, this can make a significant difference due to the structures and dimensions encountered by a bullet upon impact.

Bullets of a specific weight, velocity and construction behave differently from one another even in the same caliber. Averages across several tests should be used to smooth out anomalous results (manufacturing or testing inconsistencies).

Ballistic gelatin, albeit a "better" substitute than wet newspaper, doesn't behave identically to animal tissues because unlike a block of 10% gelatin, real animals have bones, cartilage, sinews and differing densities and thicknesses of muscle, fat, organs (the liver is fairly stiff while the lungs are quite soft) and in the case of a person, clothing. Bullets do strange things in real tissue, passing through protective gear, clothing and so on that they do not seem to manifest in homogenous anatomically incorrect substitutes.

Take this type of testing with a big grain of salt. Even if the unscientific 7 yard test were repeated at a distance of 100 yards and then 250 yards, the results would differ substantially but I doubt the fearless tester involved would necessarily understand why.

I had a carpenter do some work on my place a few months back. He was ex navy. He started talking and he said he had a medical discharge and he was wounded in Iraq. I was very curious but didnt pry, but he told me about it after a bit more of talking.

He was hit in the shoulder with a 7.62x39 ak round. It completely shattered his shoulder, collar bone, and severed the bone almost in half at the arm coming to the shoulder. And yes, I asked if it hurt. He said no cause it was complete and udder shock when it happened. He cannot raise his arm above neck height anymore, and like 5 or 6 years later still goes to rehab for it. I would say that is pretty devastating tot he human body. Video is fud, bunch of wet newspapers....

stupid, he should have used more wet phone books to see how far the penetration is.

I think it's funny how the guy says "I'm sick of you're modern warfare 2 never shot anybody s***" Whats this guys guys credentials other than looking like a tactical hipster version of wheres waldo? When has he ever had to use a firearm in a defensive matter?

Take this for what it's worth as I am no doctor but working as a EMT I have seen quite a few wounds from 5.56 (99% of of these shots coming from a patrol rifle) and 7.62x39 (pretty popular round around here seems to most often come from a gang bangers sks)
I have not been able to notice much of a difference in wound profile besides the fact that I have seen more through and throughs with 7.62. What I have noticed is sometimes the rounds act differently. I have seen shots go through and through and patient be fine and I have seen shots with 5.56 blow a exit wound through someones back like no ones business. Also a lot of shots with 5.56 resulted in uncontrollable hemorrhage and shock and eventually death, If they were not already dead from immediate organ disruption like a shot to the heart or such. I usually give this to better shot placement but 5.56 is no slouch and a nasty little round. I would definitely trust my life to it any day.

Now use 545x39 and compare that too! Btw ak is super tacticool!

That's terrible. Way too many wounded vets from that particular campaign and they are going to need help (our help, collectively) for years, if not the rest of their lives.

Any hit that strikes bone can be a real mess - even FMJ can cause significant wounds when a shoulder blade is struck as the above injury seem to support. The connective tissue and nerves are often damaged with these kinds of hits against shoulder blade/collar bone/shoulder socket as it sounds like was the case with this poor fellow. Truly awful.

The majority of the standard issue ballistic armor stops just short of this area or provides limited protection here. I suppose there is always a weight/cost/probability argument to be made about giving our troops better and more complete protection, but it still sickens me to hear these stories.

I'm sure that camel bag helped his tests with the two different rounds.

That was the clincher for me - a big gulp on a shooting bench would have been more appropriate. The greatest strength of the I-net in general and Youtube specifically is that anyone can record and upload anything (that doesn't violate the terms of service anyway) even if its complete nonsense. The gems among the swine crap is what makes it great.
