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.
P.S. the 25 suprised me
