First of all
To understand why you need a scope bai
Human eyes have limited ability, so you can see distant targets and the environment clearly with a scope (of course! You need a telescope scope)
Assuming that the axis of the scope is parallel to the gun line, the bullet is not affected by gravity. The distance between the axis of the straight flight scope and the axis of the barrel (the bullet flight line) is X cm. The axis of the scope is aligned with the target point. The bullet must hit the target after it is launched (ideally) Click X cm
The real situation is that the bullet flies into a parabola, and the farther the trajectory is, the more severe it will drop. So the barrel is slightly lifted up.
The intersection point is not necessarily, it can be adjusted. There is a knob on the scope. It can also be seen on the TV (life and death sniper). Turn the knob from time to time before shooting the sniper rifle
Even if there is no adjustment, the wind is strong, the wind is small, the temperature is higher and lower, the air pressure is higher and lower, the bullet is heavier, lighter, faster, slower, this intersection will change, or there may be no intersection.
I may not understand after saying so much! Let me talk about another shooting term-zero
A robber took the hostage and asked the sniper robber to kill
The location of the sniper and the robber have been determined to be 200 meters
If there is plenty of time, the sniper will do one thing-zero
A target at 200 meters, aim at the red heart and shoot a bullet hole appears below the red heart and to the left it is good! Adjust the knob. The sight line of the sight goes down to the left. If the barrel does not move, you can see the center of the cross line of the sight. Move it down to the left and then hit and adjust! Knowing that the center of the crosshairs and the bullet hole completely coincide can also call 200 meters to zero
The trajectory drop of bullets at different distances can only be found by checking professional shooting records
Foreign sniper training. Every shot shot will be recorded in the notebook.
