I just read the a few years back a Swedish commision researched the US/NATO 5.56mm round and said that it is inhumane because it fragments when it hits the target. The commission recommended that US and NATO go to a Swedish 7.62mm round. After some trials it was found that the Swedish 7.62 also fragments upon impact, just at larger scale because of the increased round size.

Ain't that funny.

Wonder what on earth their motivation might have been?

Sure, cause otherwise getting shot is a blast....

So which ammo does not fragment due the impact,any way the shot is a shot,you'r dead with or with out the fragments.

Not really, if the 5.56mm doesn't frag on impact. It's like getting shot with a .22 something which my friend has been shot with in the lower torso by accident. He fell down and screamed for a little bit, but he wasn't "incapacited". In a combat situation he would have definitly been able to keep shooting back.

Maybee a little bit on the way high velocity missile rounds wound is in order here:

that little round may resemble a 22 in size, but its effects are totally different. this round is a very high velocity round. It leaves the barrel at speeds higher than 3200 feet per second. so its going supersonic. Things that go supersonic are often accompined by a pressure wave, as the bullet pushes air ahead of it as it travels, just like an airplane. That distinctive crack as the bullet flys by you is in reality its sonic boom. since mass time velocity equals a whole lotta energy transferred to the subject, it really doesnt have to be big.


http://www.rkba.org/research/fackler/wrong.html this data was produced in 1987. It delves into what some called misinformation about the round during the earlier time period.

http://www.aaos.org/wordhtml/anmt2001/sciexh/se11.htm this link is a little more modern, with a shorter more concise explanation of the actual wounding characteristics. they discovered that the temporary cavity was more destuctive than first thought, and were once again reccomending extreme debridment of the wound , to prevent gas gangrene from spreading.

enjoy.

For the 5.56 M193 and M855 to frag and produce a massive wound, they need impact velocities in excess of 2500 fps, and is only going to do it reliably above 2700 fps.

With extremely short barrels, the effective range for the frag effect with M855 5.56 can be as short as 15m.

Barrel length and ammo selection make a major impact on fragmentation range.

Even .22 can kill you,you can be lucky with .357 and survive

I think taht the 0.50 BMG ammo is the right choice

The problem with high velocity low caliber ammo is that it doesn't transfer energy efficiently to the target. That means it either goes right through you, or cuts you up real bad inside, but it takes a relatively long time to do it, so there is little shock value.
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.
