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. |

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. |
