Taylor Knock Out (TKO) Scale

[mesinge2]

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.



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.


Edit: forgot 10mm, Corbon Self-Defense 10mm Auto 165 Grain JHP's TKO is 11.59

It would be nice to include a few standard rifle loadings (223, 30-30, 308, 300 Win Mag, 460 Weatherby) just to give an idea of how far down the scale handguns are; regardless, I don't think I'll be gpoing elephant-hunting with a Baby Browning anytime soon .
