Who makes Igman ammunition ballistics

GEE

The line of sight (blue) is a continuous stretch with no deviations in height or width. The trajectory of the projectile (light blue) shows a rise and a fall. A fired projectile is slowed down by gravity and air resistance after leaving the barrel and pulled towards the ground. It follows the rules of physics and falls. Without air resistance and gravity, it would follow the barrel axis (black). For hunting purposes, the barrel is aligned according to the trajectory of the projectile so that a maximum high shot of 4cm is reached at 100 meters (orange). The projectile has already crossed the line of sight once on the way to the target (red). After the maximum high shot is reached, the projectile begins to sink and crosses the line of sight (green) on its way again. This overlap represents the most favorable shooting distance. Even at this distance and little beyond that, the center of the target can be sighted. Hunters who often take long shots can also increase the high shot from 40mm, for example to 50mm. This logically results in another GEE.

The evaluation of a ballistics program serves as an example for illustration. A .308 Winchester with 165 grain Nosler partition bullet was chosen as the cartridge. The muzzle velocity is 800m / s. The black line corresponds to the line of sight and the red arc to the trajectory of the projectile. The first intersection of the projectile and the line of sight is 36 meters. At 100 meters the projectile has reached the maximum height of 40mm above the line of sight. The second intersection of the falling projectile is 166 meters. So the GEE for this cartridge.

With the same cartridge as described above, this evaluation makes it clear why the GEE is legitimately used. In this representation, a trajectory is simulated in which the sight shot falls exactly at 100 meters. In the image above, the sight shot is at 166 meters. If the sight-in shot is already at 100 meters, a deep shot of 7cm is already made at 166 meters. Anyone who hunts in a purely forest area will hardly have to rely on the 166 meter sight-in distance. For everyone else, the GEE is a recommended and inexpensive method to safely guide the ball to the target, even over long distances.
