THE 338 SABI

The cartridge is often referred to as a 30-06 case neck up to 338, but the only similar dimension in the whole case is the diameter of the base and all other dimensions have been derived at for different reasons.
The cartridges were designed to give us something between a 30-06 and a 375 H+H and both the rifles and ammunition are produced by us. The low velocity of the heavy bullet makes it an ideal caliber for the bush hunting on big game. The 338 SABI has been successfully used on water buffalo, giraffe, eland and hippo. In all four cases a 250 grain Hornady soft were used.
The game of Africa requires a heavy bullet at a velocity where the tough skin and sand in the hair do not destroy the bullet before it can do the work. The slogan from one of the writers who tested the caliber says: "for Africa nothing comes better than a 338 SABI". . The popularity of the 338 SABI stems from the low chamber pressure required for its performance and the excellent sectional density of the 338 bullets and makes the 338 SABI the most versatile caliber available, shooting bullets from 200 to 300 grains.

Table 1

The good sectional density of the 338 bullet is the reason for maintaining the velocity and the excellent penetration, while the bullet head is not destroyed by high velocity and is known for instant killing. Because of the low recoil of the caliber, rifles can be small and light, making it easy to carry.
We have a very interesting formula for comparing the ability to penetrate and to kill. We took the ME, multiplied it by the SD and then multiplied by the bullet weight, retained after impact at a certain distance. Tests have proved that bullets hitting at 2800ft/sec rarely retains more than 45% of the original weight and bullets hitting the target at 1800ft /sec seldom loses any weight. When we use a bullet of 180gr and destroy 50 % through velocity we only have 90gr left to do the work.
