5.45 is more dengures then 5.56 i think

How is it more dangerous?

One more thing i feel needs to be mentioned abot HVM 5.56 and tissue...when one of those bullets hit, as it enters it creates a very high zone of negative pressure behind it. This wake greatly disturbs the sorrounding tissue..creates a very large cavity, and even can break bones in passing.

You hit a person in the right place..they aint getting up.

You hit a person in another area that aint critical...well without proper wound treatment, gas gangrene forms in the cavitated area and you go bye bye...eventally.

As I said, getting shot is not a treat, no matter the cliber...You can onlytake this "humane" crap so far. As to the saying that the 5.56 is like a 0.22, well thats sort of true, but the 5.56 military rounds have a larger amount of powder pushing them, so really, they are much more leathal.

The other extreme is something like a .45 ACP, which is slow, but super heavy, and high caliber. When it hits, almost all of it's energy is transfered at once to the target, meaning massive localized damage. this produces shock symptoms faster and more reliably, and that's why it's a "stopper".
It's like the difference between being stabbed or hit with a baseball bat: Both will kill you, but one will knock you on your ass first.

I may be wrong here, but the impact felt by a target would be no greater then the recoil of the gun. Most people that describe being shot find the actually impact no greater then a hard punch.

That may be true for small caliber (high velocity) bullets, but not .45 that Jamoni is talking about...

No handgun round is a guaranteed "stopper".

I don't know, Sir, one of my neihbours has a 12 gauge break action pistol that would do someone's business for them pretty regular.

jaeger wolf:yep.it is true.some friends of mine who are in the army told me,that they tested ballistic vests, 5,56 penetrated unproperly front side of the vest and 5.45 penetrated the front side and back side too

That wouldn't make sense, as the 5.45x39 is slower and smaller then the 5.56.

Here's some wound profiles, it show sthe 5.45x39mm doesn't fragment as much as the 5.56mm
