At present, it has been scientifically verified that the earth is (ellipse) circular. However, the flight paths of missiles, aircraft and bullets are all irregular or unequal parabolic.
The sniper's eyes are aimed at straight lines through the magnifier and the sight. From a theoretical point of view, the point or target of the bullet is the intersection of the parabola drawn by the bullet's trajectory and the sniper's sight line.
2x, 4x, and 6x are medium and short-range magnifiers, 8x and 15x are medium and long-range magnifiers. From the actual situation of an assault rifle or sniper rifle, the scope and barrel It is a parallel relationship between up and down. Different magnifications and different distances need to learn to adjust the aiming point of the magnification (high and low) if you want to accurately focus on the target.
In layman's terms, the aiming point in a sniper's magnifier is not the end of the line of sight, but the end of the bullet's trajectory. The scope only has the effect of narrowing and magnifying the distance. That is to say, if the magnifier and the barrel are on a parallel line, the bullet shot will deviate seriously from the target point.
Modern sniper rifles need to focus on a target 1000 meters away, so wind direction, temperature, gravitation and other issues must be considered. Because the bullets fly far away and the bullets themselves consume energy, natural factors must be considered, otherwise it will be difficult. Focus on the target point.
Whether it's actual combat or the so-called "chicken-eating" game, if you want to focus on a target 600 meters away, you must consider external natural factors, including the aerodynamics of the bullet, the weight of the bullet, the trajectory of the bullet, and the time of the trajectory deformation. And distance, so that you can cause effective damage.
Modern assault/sniper rifles, but all bullets of 7.62mm or above, whether it is AK-47 assault rifle Soviet/Russian, SCAR-H (heavy), CZ-805, Karabiner 98k, etc., are equipped with 4 times, 6 After the magnification optical sight, its effective killing distance can reach more than 1000 meters.
