Although TKOF is a numeric mathematical approach for evaluating the effectiveness and stopping power of hunting cartridges (always subject to much debate), it may be appropriate here to compare the stopping power of pistol cartridges when you are looking to throw the biggest bullet and its mass that you can at a target.

 

I don't put much stock into TKOF. It's an arbitrary measurement - Bullet weight x Velocity x diameter divided by 7000? meh.

Of course we know its not that simple though, if your proj goes through your target, any residual velocity is, at best wasted, and at worst damaging something you didn't intend. Consequently I think the TKOF would have to go out the window if the proj doesn't stop in your target.

 

The fact that every department with enough budget can come up with their own standards (FBI, DHS, military) with their own intermediary barriers is why all of these disparate types of ammo can be "best" at a task.

 

BTW, if someone thinks a formula is wonky because it has a seemingly random constant, better stay far far away from ballistics textbooks

Agreed, but an quick and easy way to compare and convert the result into pounds. When I came across it I thought it was interesting how hunters in the mid 20th century determined what cartridge they wanted to use to bring down Rhino's, Elephants, etc.
