the .40S&W gets most of the way between each. You get 15 shots in a double stack mag (compare 17 for the 9mm and 13 for the .45 in Glock double-stacks), can make it on a smaller frame pistol, and you split the difference between 9mm and .45ACP in terms of cross section. The modern cartridge and barrel mean that higher pressures are used, although the recent .45GAP circumvents this. I think that it's enough of what everyone wants to do well.

It shouldn't be a surprise; the phenomenon Fred referred to when a .223 hits a rabbit also happens with people; the .50 BMG has 17,000J of energy, about 5x that of a .308 winchester, a round known to have a temporary cavity the size of a volleyball. If cavity is proportional to energy, we're talking 70% larger than that, or maybe 15" in diameter, larger than the typical front-to-back dimensions of a person.

Re: HIGH-TECH-Arrived-Gun Damage
Right now I've only got hearsay:
"There was a documented instance of an enemy sniper in a water tower behind severed in half horizontally at the waist by a M107 sniper rifle from a range of 1,700 yards. " From http://answers.yahoo.com/question/in...4173800AAOlv40 I read this account somewhere else; it's the same story. I cannot, however, find the original documentation. The video I referenced has since been shown, I see, to be a myth; its documentation of exploding varmints with high power rifles. I'm still looking for primary sources, but the tower story I've run across more than once.

Re: HIGH-TECH-Arrived-Gun Damage
Actually in the 70's numerous police experienced "blow through" on suspects, these always were failures to stop as well. I don't have a link but I did see a marine DVD of a .50 kill that can be described as "red smear".

Re: HIGH-TECH-Arrived-Gun Damage
Not completely related, but in Stephen Ambrose's books about tha big Dubya-dubya-Aye-Aye, German soldiers often complained that the .50bmg was a criminal weapon to use against infantry, the german shutzen having an rational fear of it causing dismemberment.

Re: HIGH-TECH-Arrived-Gun Damage
I just wanted to point out that the correct terminology for the phenomenon you guys are discussing is "hydrostatic shock", not "ballistic shock".
And no, hydrostatic shock has not been proven to be a major factor in death by gun shots, and for the most part, is a bit of an urban legend. I mean, we know it exists, but it isn't a big deal. Direct damage to internal organs, blood loss, and nerve damage are the real killers. |
