American PH

Norma-ELK-Box-3D-and-AMMO-smallTraditions are very different around the world. And why not? This is the kind of thing that makes other cultures so interesting. Sure enough, this is also true for hunting.

For instance, Americans often use lighter bullets and higher muzzle velocity. Average ranges are also longer. Europeans traditionally use heavier bullets and moderate velocities. They shoot at shorter ranges. This has a direct effect on the choice of bullets, Stateside and in Europe.

African PH

The concept behind Norma’s AFRICAN PH range is different. Based on many generations of experience of reputable African Professional Hunters, this range of cartridges has been developed with the aim to optimize ballistic criteria such as Bullet Momentum, Sectional Density and Deep, Straight-line, Bone-breaking Penetration. These factors in turn, are responsible for KO or Knock Out Value, probably the most important ballistic criterion of all, for stopping a determined charge from one of Africa’s Big Five.
