Ballistic Silence of Special Years

Chapter 149 Deviated
It is said that if the wind is not strong at a distance of more than 300 meters, the ballistic trajectory will not be affected too much.

The head target used for sniping is much smaller than the ordinary chest ring target, and there are also 10 rings on it.

According to Hou Jun's requirements, you must hit 10 rings to be considered qualified.

To hit the 10-ring bullseye at this distance, you must have more accurate distance data.

If you don't have an observer or a rangefinder, you can only measure the distance manually.

According to the current conditions, Li Zheng has three ranging methods——

The first is to rely on the rangefinder differentiation scale to measure range.This method is very simple, because in the center of the 88 sniper scope, there are seven "--" horizontal lines from top to bottom. The root "--" represents the distance of 1, 200, 3, 4, 5, and 6 hundred meters respectively.

The blank position in the center of the two horizontal lines is the key to distance measurement. Use the blank space to trap the target (generally based on the target body width of 50CM), as long as it can trap the left and right sides of the target, there is no extra space, which means that The standard number next to the horizontal line is the distance value.

The second is to use direction division ranging. In addition to the "--" horizontal bar from top to bottom in the scope of the 88 Sniper, there are 5 divisions on the left and right sides of the scope, and each division value is 1 mil.

When the sniper estimates the shooting distance, he uses the direction-differentiated side line to cover the target (also based on the commonly used value of 50CM for the human body), and sees how many differentiation lines are blocked on the other side of the target, that is the target's corresponding close distance location.

Of course, getting the secret position does not mean that you can get the correct distance, because you have to apply a set of special calculation formulas to get the correct distance value.

The calculation formula is: distance = target interval X1000 divided by secret position.

For example, the frontal width of a human figure is 0.5 meters, and 2 dense-bit reticles are blocked on the reticle.

Then, the correct distance should be = 0.5X1000 and then divided by 2 = 250 (meters).

Of course, this kind of simple math problem did not pose any difficulties for Li Zheng, a famous college student.

Another is the visual distance method.And this visual distance method is the most common distance measurement method in the Army Special Forces, but this method requires long-term training and rich experience accumulation, and it needs to continuously conduct various tests on different objects in the field, so as to obtain Choose the most accurate ranging method that suits you.

The visual inspection method also includes the comparison method, the judgment method according to the visibility, the eye jump method and so on.

Even, in the PLA Army Special Forces, there is a method of judging distance at night.

Of course, recruits like Li Zheng are pure rookies at the moment.

Before the live ammunition sniper training, Hou Jun explained to them the relevant distance measurement knowledge, but Li Zheng has not even learned the visual measurement method, let alone the advanced stuff of night-time distance determination method.

A rookie is a rookie.

Li Zheng chose the simplest and most direct method to measure the distance - using the seven "--" in the sight mirror to measure the distance.

The time is too short to save a little bit.

He put the scope on the head target—this is the most common head target, there are many types of head targets, some have only one head, and some have a small shoulder.

The head target that Li Zheng saw so far was the one with shoulders.

This is the easiest.

Because the shoulder represents the shoulder width of the human body, and the width is also 50CM.

It means that you can use the upper and lower scales to directly set the distance.

He moved the front sight up and down slightly, from the first "--" all the way down.

When it reaches the third scale, it seems to have been filled.

Take a closer look, there is not yet, there is a little gap.

Li Zheng immediately concluded that the distance was about 360 meters.

At this distance, the impact of an error of 20 meters or [-] meters is not very big.

Li Zheng immediately used the second arrow sight to trap the center of the ten rings of the head target, then took a breath, and slowly began to exhale.

The index finger has already pressed on the trigger, press it lightly, until the pre-pressed position becomes hard, at this time, just use a little more force, the bullet will come out of the chamber.

However, the advantage of the scope is that you can see the ten rings clearly, but the disadvantage is that it shakes a lot.

Time passed by second by second.

30 seconds is not long.

Ranging took about 15 seconds.

Now it's more than half of the time, only ten seconds left.

"calm down……"

He kept hypnotizing himself.

"Lower the breath...lower the breath..."

Eventually, the shaking of the arrow crosshair finally slowed down and became smaller.

When the top of the arrow lightly crossed the ten-ring bullseye, Li Zheng pressed the trigger.

bah—

A special ejection chamber for 88 sniper.

Li Zheng raised his head slowly.

The bullet has hit the target.

A cloud of dust splashed on the ground behind the head target.

Li Zheng looked through the scope and zoomed in.

The bullet hole is on the upper right of the 8th ring...

"Fuck!"

He couldn't help cursing.

You are scolding yourself.

Obviously caught the middle of the 10th ring.

Why is it on the upper right?
Not far away, Hou Jun picked up the observation mirror hanging on his chest and looked at Li Zheng's head target.

After looking at it, he put down the observation mirror, curled his lips, and shook his head, looking very dissatisfied.

Li Zheng clenched his fist and slammed it heavily on the nearby haystack.

This is the second time I fired it today. It's been a long morning, and my two shots have missed...

　Today is the storyteller’s birthday, and I thought it would be four more, but it turns out that today is the holiday, and I went home late after having dinner with my family. This chapter also involves a lot of hard knowledge of snipers. I must treat it carefully, and I have to remember some details, so write It's a little slow.

　　Happy birthday to the storyteller brother!
