The "Taylor KO formula" was developed by John Taylor. John Talyor was an extremely experienced African hunter, his formula was based on killing thousands of large game animals with nearly any caliber you can imagine. This formula is designed to give you a relative "killing power" number for a given caliber, the higher the number the better. For example the 44 Magnum, which most handgunners consider an acceptable hunting caliber, with its standard 240gr load gets a Taylor KO of 20. A fairly typical 454 Casull 300gr load gets a 30, your standard 12 gage shotgun slug load gets a 53.
