There are two basic requirements for a cartridge when hunting the big stuff in Africa: STOPPING POWER and PENETRATION

There has always been and most likely will continue to be in the future, a debate amongst gun enthusiasts as to which rifle in the world meets the above requirements. Shooting bullets of more than 500 grain and at velocities in excess of 2300 feet per second, requires some gun – believe you me!

Let’s take a look at the famous Jeffery, certainly a rifle and manufacturer which has stood the test of time. For many people super high velocities and high energies are like a drug, the more the better. THEY ARE WRONG!

We have been in this business long enough to stand our ground on this argument and we have also seen our fair share of big game trophies shot, by virtually any calibre you can think of in this class. Beyond a certain point no more killing power is needed. Animals are living creatures, not armoured cars as some romantic Africa Would Be Game Hunters like to promote on their get rich quick dvd’s. You can kill an elephant or buffalo only once, not twice …. For example, the capacity of the .500 Jeffery is larger than the .460 Weatherby and if loaded to the same pressure level of 55,000 psi, it would produce superior balistics, but to what end? The following information is credited to well known author Tony Sanchez-Arino.

We hope that the following facts will help you to better understand some important points about the .500 Jeffery:

  • A bullet of 535 grains (34.5 grams), at 2 400 feet muzzle velocity, takes 0.0709 of a second to cover 50 metres, 0.1467 to 100 metres and 0.2274 to 150 metres.
  • With a side wind of 2.20 metres per second the bullet has a deviation of 6 milimetres at 50 metres, 22 milimetres at 100 metres and 50 milimetres at 150, which produces a very high accuracy level.
  • The trajectory of the bullet is: 1,5 centimetres high at 50 metres, 0.0 at 100 and 7.5 cm low at 150, which is similar to many smaller calibres shooting a bullet less than half the weight of the .500 Jeffery.

The famous ammunition factory of Norma in Sweden has recently introduced a new line of cartridges named the “African Professsional Hunter”, including most of the more popular calibres but altering the traditional ballistics, increasing the bullet weight between 5 and 12%. The Jeffery is also on the list, with the following innovations:

  • The bullet is 570 grains instead of 535.
  • Muzzle velocity 2 200 feet per second, at 50 metres 2 097 and at 100 metres 1 997.
  • Muzzle energy 6,127 ft/lbs., at 50 metres 5,568 and at 100 metres 5,050 foot pounds.

Now, we don’t necessarily agree with the Norma heavier bullets, however, we can say this unconditionally – The .500 Jeffery is a serious and powerful stopping rifle for big game hunting in Africa! A rifle we believe is about to be re-born in Africa and certainly up to any test which comes it’s way!
