found these FBI stats on another forum:
What better place to start then the statistics kept by the FBI. Here are a few examples of performance of different bullets. ATI=Average incapacitation time. This is an estamated number based on their formula of shock and blood loss. All of these were among the top performers in their respective calibers.
exp pen shock one shot stop ATI
Cor-Bon JHP +P 90 0.58 9.0in 467psi 70.0% 10.2 sec 380acp
Cor-Bon JHP 115gr 0.55in 14.2in 626psi 90.6% 8.8 sec 9mm
Federal Classic 125 0.65 12.0in 1487psi 95.8% 5.7 sec357 mag
Remington Golden Saber0.68 12.0in 771psi 93.8% 7.9 sec 40 S&W
Cor-Bon JHP 185 0.7 11.3in 920psi 91.7% 7.2 sec 45 ACP
What does this tell us, well first of all the puney little 380 is far from worthless seeing as 70% of the time one shot was all it took.
Although the 45 did beat the 9mm in one shot stop ratio the margin was so slim that it is hardly noticable.
The myth on larger bullets always being more effective is busted here as the 357 magnum (9.1mm) has a higher one shot % and a faster ATI then any of the larger bores.
The choice of bullets seem to have more of an effect on performance then the choice of caliber as each had good and poor performers.
