They then apply a formula to their recorded velocity figure to correct for this distance, and they call that ... A velocity of 671 f.p.s. for any projectile gives the same energy number in foot-pounds as the weight of the projectile in grains. For example, an 8-grain pellet traveling 671 f.p.s. generates 8 foot-pounds.

But once we have a psi to pellet weight ratio then we can use this formula to calculate any velocity for any pellet weight as well as foot pounds. An earlier blog stated that to use the Eun Jin 16 grain .177 cal pellets with accuracy it was necessary to have an airgun that could produce 25 foot pounds at the muzzle.

There is no perfect way to quantify a bullet's terminal performance - I want to make that clear before I go any further. I think TKO does a better job of doing so than foot-pounds (ft-lbs) of energy, ... You must have a bullet of suitable construction - something that no formula does (or can) take into account.
