Taylor's knockout factor, or TKO, kind of adds a new twist to the standard FPE formula that quite a few folks in the shooting world treat as the end-all, be-all. He factors in caliber. It helps to explain things like why an old nugget like the .45-70 is a bit more effective on bear than a smaller round such as a .243, although each may be equal in terms of FPE. Taylor's formula may not be entirely scientific but it is supported by field experience. He was basically concerned with what it took to stun an elephant, something important in his line of work. The days of W.D.M. Bell potting them point-blank in the ear with a 7mm Mauser had long passed. The remaining pachyderms weren't dumb.
I'm also into adult airguns. On paper, while a .177 pellet has the same FPE as a .22, the larger pellet often out-performs it. The TKO does show the difference. Try it. Might support some of your own opinions. 😊
