Won't cause me to rethink much. These are done and posted all of the time different groups The FBI ect. Result tend to reflect what they want. There are no magic bullets.
The best round is the one you used when you killed the BG.
Simple small sub compacts go a little lighter, compacts a little heavier, full size go as heavy as you want. You have a lot of wiggle room to work with.
Focus on hitting the target no so much on the round.
Interesting data. The golden saber 185 gr would appear (on paper) to be the best 45acp based on expansion and 15 inches of penetration.
If you lime to read about terminal ballistics then grab a copy of Handgun Stopping Power by Sanow & Marshall. If ur too cheap to buy the book, then order it intra-libraryloan. They rank ammo based on actual street shootings. Verrrry fascinating stuff. Also discusses other studies like the goat tests. Some of the results in ammo performance were surprising.
I look at this stuff but just don't get all fired up about it. Daughter carries a 380, loaded with 95gr flat nose rounds. They do a great job in the 380 for personal defense .
No doubts about her ability to hit the target.
wife has 124 GR SEMI JACKET HOLLOW POINTS in her .38 They seem to fill the largest number of needs in that weapon. I stick with 124gr JHP in my SR9C.
Come SHTF I have a shtf load of 115gr ball.
If that don't kill them I guess the AR would have been a better choice.
Fancy bullets are pretty and all, impressive stats too. But in the end they only expand about 10-15% more than plain ol' bullets at $1.30 per round vs. about $0.40.
I do have some of them but, just stick with the major brands and hollow points and you'll be just fine.
Remember that plain or fancy, the bullet can only do it's job if you do yours.
Remember the real estate slogan, "Location, Location, Location"! (shot placement)
These studies are based on actual street shootings (unlike Fackler's work which tries to determine stopping power by shooting gelatin.) They also cover dozens of other ammo tests done by fed & state agencies. I think these guys have a 3rd book out now. Fascinating stuff, you'll read cover to cover and mark passages like it was yer bible. Really, there is some cool stuff in their books. Before I read them I too suffered from mistaken beliefs about my ammo.
You cannot kill David Soul with a single shot from a 9mm.* It's in his contract!
*Obscure reference to a made-for-TV reenactment of the legendary FBI-Miami shootout that spurred the FBI tests (that eventually determined that the 230gr hydrashok was the optimum duty cartridge against all barriers.)
