A few years ago Hornady came out with a calculator that attempted to offer a better solution than the archaic system of using kinetic energy as a method for determining the lethal performance of any given cartridge/bullet combination. The kinetic energy equation factors two things 1: Mass, 2: Velocity. It heavily favors velocity as it is squared in the calculation. The problem with kinetic energy is that it does not account for why heavy for caliber bullets are preferred when hunting larger game, in essence it fails to explain the "penetrative" qualities of heavier bullets in a given diameter, even though such rounds produce slower velocities at the muzzle.
Hornady Has introduced their system which tends to match up with what most guides will tell you to tote along on a hunt. This however is no the end-all/be-all of the "enough gun for your game" debate, but it does help clarify caliber selection when shopping for a new rifle.
I made this video explaining how to calculate the H.I.T.S. value of a given load and show examples of calculating some of my own calibers for demonstrative purposes, then finish by discussing what professionals recommend and show how that dove-tails nicely with what Hornady suggests as a recommendation
