I have a great amount of respect for Martin Fackler and agree with much of what he wrote in his analysis for the FBI after the Dade County shootout. As I was in law enforcement at the time and had read much about calculated "energy" levels delivered by various calibers of handgun, his writings were revealing. I also happen to be an individual who has hunted and guided professionally for big game off and on for the last 40 years. I have noticed that people who have done quite a bit of hunting become somewhat cynical about writers who pontificate on this caliber or that caliber in their never ending search for the ultimate handgun or rifle caliber. As I live in a rural part of America and as we were involved with a mobile business that would kill and slaughter animals on site I had an opportunity to test both caliber of handgun and bullets that were available for said handguns. I can tell you that paper ballistics and performance can be vastly over rated. Especially by some who are not only searching for the ultimate handgun but also for a paycheck. I can also tell you that while there are some differences in shooting people vs. large animals, there are also some parallels. I can say that bullet design technology has improved large rifle performance substantially but not as much in slower moving handgun calibers. I can also tell you that frontal area is important but has to be combined with penetration. Hence the lethal combination of semi-wadcutter design in a hard cast bullet. Sound like Elmer Keith or Ross Seyfried or Bryce Towsley or Finn Aagaard?

That little solid chunk seems like it would do some damage when hitting bone, etc. The only downside I see is for defensive rounds, obviously there would be a certain risk of bystanders being struck. But camping or hiking I can see advantages. <br /><br />Also I know this isn't exactly the best source, but pertaining to your discussion, if you have ever seen the TV shows Crime 360, The Shift, and many others, the ballistician always weighs the spent round after it is retreived from the body. I always wondered why they couldn't tell by relative shape, however, bullets shred and lose mass as they come into contact with objects. I always enjoy guessing what round it is when the ballistician or the morgue worker weighs the bullet. "The bullet retrieved from the lower torso is 110 grain s..." - then I blurt out "it was 9mm!" ;)Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-5557913977913148366.post-7437800597341091362016-06-04T10:32:49.962-07:002016-06-04T10:32:49.962-07:00Hi Greg,

Here are several papers on describing and identifying gunshot wounds by medical doctors; note that they all say that the caliber of the weapon that made the shot must be determined by measuring the bullet itself, not the diameter of the wound, just like I said:<br /><br />http://www.tdcaa.com/sites/default/files/page/5%20FRI%20INV%20Molina%20Gunshot%20Wounds.pdf<br /><br />"Caliber Determinations<br />The caliber of the bullet that caused an entrance in the skin cannot be determined by the diameter<br />of the entrance. The size of the hole is due not only to the diameter of the bullet but also to the<br />elasticity of the skin and the location of the wound. An entrance wound in an area where the skin<br />is tightly stretched will have a diameter different from that of a wound in an area where the skin<br />is lax. Similarly, the size of an entrance in bone cannot be used to determine the caliber of the<br />bullet that perforated the bone though it can be used to eliminate bullet calibers."<br /><br />http://www.archivesofpathology.org/doi/pdf/10.1043/1543-2165(2006)130[1283%3APPOGW]2.0.CO%3B2<br /><br />"Generally, bullets are identified by their caliber or diameter<br />and whether they have a metal covering or jacketing...

IIRC this was in the 1970s and prior to any really functional hollowpoints; wadcutters wete his load of choice in a revolver due to the perceived increase in frontal "cutting surface," and his partner carried a 1911 with the chambered round being a wadcutter, and FMJ in the magazine for feeding reliability.Anonymoushttps://www.blogger.com/profile/14512074394101250279noreply@blogger.comtag:blogger.com,1999:blog-5557913977913148366.post-78673765514053130982016-04-02T16:55:27.250-07:002016-04-02T16:55:27.250-07:00>we would not expect to see very much differenc...>we would not expect to see very much difference at all between a .30" caliber "through and through" FMJ wound and a .22" caliber one, and indeed, we don't.<br /><br />Who is "we"?

Doesn't seem like that would be true. But I don't know. Anonymoushttps://www.blogger.com/profile/11490141602853235997noreply@blogger.com
