Taylor Knock Out (TKO) Scale
I thought some people might like this data. I computed it based on the factory released velocity information with their corresponding barrel lengths during their tests.
Added at request of steve4102 Corbon Self-Defense 10mm Auto 165 Grain JHP's TKO is 11.59, impressive
The formula used in the John "Pondoro" Taylor Knock Out (TKO) Scale for measuring power of calibers. Developed by an African hunter named John "Pondoro" Taylor. Basically, you multiply diameter of bullet in inches times muzzle velocity times bullet weight in grains divided by 7,000.
P.S. the 25 suprised me
