finally got around to viewing this video that Dave in WV posted earlier:
https://www.youtube.com/watch?v=tku8YI68-JA informative, yet somewhat perplexing too...
if one factors out his comments on rifles--and only focus on handguns--a few points he notes might be:
1. six out of seven victims (about 86%), shot with handguns survive. quick, critical care is a factor though. in hollywood style, likely many of these victims are only hit once--or twice--like the guy in the video at the 14:40 mark. "multiple hits" aren't really addressed.
2. he does indicate a lack of penetration--likely due to fragmentation--as an issue. while he is referring to the results on expanding bullets with actual victims--in testing pills in wood, wetlap, water, etc., at times the failure in hollow points is the nose turning inward--resulting in essentially a fmj. occasionally, there is core and jacket separation--but the core often plows on ahead, somewhat like a swaged lead pill would do. this was especially the case with many pills of yesteryear.
3. he notes--for lack of a better phrase--the "vertical axis" which is quite narrow, and a change in target design to reflect that. true, as in a decent target, this area is essentially about 6 inches wide and 20 inches high.
4. one is left with the impression that he believes or indicates that there isn't much delta in the effective performance of the "Big 3" (9 MM, .40 S&W, and .45 Auto), and indicates that it depends on the chance that the pill will penetrate enough and perhaps sever a vessel, etc.
5. yet curiously (while he was talking about rounds at 12:35 in the video), he indicates that a heavier, bigger pill will cause more damage and injury, resulting in more bleeding.
perhaps a little confusing, but worth viewing...
