I prefer the two formula of A-Square, the Penetration Index and the Shock Power Index, to the antiquated TKOF.

By hunting DG, it is in a first time all about the first shot placement, where precision and depth penetration count, and only then, especially if something has gone wrong, the schock power for a sufficient stopping of a charge. If you take both factors into account, the situation is very different with many cartridges.

If you only make backup, you can concentrate more on the shock effect, but since the absolute majority of us hunt above all, and very few have to make their backup, both indexes should be taken into account. You can see immediately which cartridges are ahead and have the compromise between depth penetration and shock. They are not the biggest, but also not the ones that are so highly praised by the majority of the African hunters nowadays in terms of their effect.
