310 sniper game

In the camouflage competition, Li Yu and Zhang Li scored the highest scores.

But then comes the main thing.

At around three o'clock in the afternoon of this day, the sniper competition officially began.

The schedule of this sniper competition is not complicated, the shooter snipes at different distances in three ways: lying position, kneeling position, and standing position, and the one with the least time and the best score wins.

Because the eight or eight snipers are used, the sniper distances are 600 meters, 700 meters and 800 meters respectively.

600 meters in a standing position, 700 meters in a kneeling or sitting position, and 800 meters in a lying position.

All competitors go to the designated position and shoot at the target target in the designated area.

Li Yu and Zhang Li also followed the large army to their designated area.

Zhang Li first spread a large piece of oilcloth on the ground, and then put the meaning of guns and utensils on it.

Because the time had not yet come, the game had not yet started, and both men were just quietly preparing.

After about three minutes, the leader of the referee team came behind everyone and shouted with a loudspeaker: "Attention all teams, the sniper competition will start immediately, now start the test shooting, each team has three chances!" ”

As soon as they heard the password for the test shot, everyone immediately moved, and Li Yu picked up the 88 sniper.

The first thing is to kiss Baba, and pray silently in my heart.

This is actually a psychological suggestion, a way to quickly calm yourself down and put yourself into a sniper state, not really pinning the results on the gods.

Of course, from another point of view, the accuracy of the 88 sniper is indeed not good, and the results of the game sometimes depend on a little luck.

Internationally, it is generally said that the accuracy of sniper rifles will mention terms such as "R50" and "MOA".

At present, the accuracy measurement standards of domestic rifles are R50, R100, calculation deviation and shooting intensity boundary.

R50 is a certain number of projectiles at a certain distance, taking 50% of the impact point dispersion radius.

R100 is a certain number of projectiles at a certain distance, and the dispersion radius of all the impact points is taken.

Take the domestic 88 sniper as an example and its acceptance criteria as an example: the shooter shoots three targets at a distance of 100 meters in a lying position with support, and shoots 20 rounds at each target to find the average value. When the average dispersion of this sniper rifle meets the two indicators of R50≤2.9cm and R100≤8.7cm, its accuracy is considered to be acceptable.

The division of shooting accuracy of sniper rifles in Europe and the United States usually uses "MOA" as the standard unit, which is also a word that many "military experts" often like to say today.

MOA is a very small unit, and the accuracy of 1MOA is about 100 yards (91.44 meters) away, and the spread of bullets is not allowed to exceed 1 inch (2.54 cm) in a circle, which is about the size of a one-dollar coin, which is the kind of accuracy that will hit your left eye and never hit your right eye within 100 meters.

The accuracy of the Type 88 sniper rifle at a distance of 100 meters is 100 cm according to the Chinese standard R7.

So 88 sniper wants to play 1MOA at 100 yards, so let's wash and sleep.

China's high-precision sniper CS/LR4, also known as Type 26, or 260,000, is the only sniper rifle with good accuracy.

Although the gun was not lightly blown at the beginning, and later it was not light, it is a sniper rifle with relatively high accuracy among the current domestic firearms. It uses a CS/DFL3 high-precision sniper bullet, which is enough to shoot an accuracy of 1MOA in the effective range, which is even slightly better than the American-made M24 sniper rifle, and is barely considered to be a first-class level in the world.

According to some retired veterans, some of the top domestic snipers are in the West. In the Tibetan plateau environment, the LR4 "Type 26" high-precision sniper hit the bullseye at a distance of 1200 meters, 1200 meters is not too far, but it is really difficult in the plateau environment, indicating that the accuracy of the gun is still very good. And the price of this gun has been greatly reduced, and the purchase price is about 30,000 yuan. But the scope is still expensive and not cost-effective.

Of course, everyone uses eight or eight snipers in this competition, so the starting point is the same, and the final result depends on all ability!

In order to ensure that today's game shines, the first thing Li Yu has to do is to adjust the scope of the sniper rifle.

The quality of the scope, whether it is accurate or not, is directly related to the result of the game, so the first step is to zero the scope.

Generally speaking, after the bullet is fired, the bullet will rise first and then fall, and the flight law of the bullet is often traceable. Generally speaking, the zeroing distance of the optical sight of an automatic rifle is generally 100 meters, and the zeroing distance of a sniper rifle depends on the actual situation.

The zeroing of a sniper rifle is usually adjusted by two knobs on the top and side of the optical sight. If the impact point is up, use the knob to turn it up.

At the top of the knob, counterclockwise for upward adjustment, clockwise for downward adjustment. There is a mantra for the sight to zero, called "where to adjust the target", which means that if the impact point is high at the zero return distance, then the sight is adjusted up. The same is true for the left and right.

Moreover, the zeroing of the sight does not depend on the feeling of twisting the knob up, down, left and right. In general, the adjustment knob needs to be based on the distance between the impact point and the preview point. Taking a 15x mirror as an example, every "click" sound when turning the knob represents an adjustment of 1/4 of the MOA.

Li Yu test-fired two shots and quickly zeroed out the sniper scope.

After a while, the leader of the referee team shouted again: "The sniper competition has officially begun, the first time, six hundred meters of shooting, start!" ”

As soon as they heard the starting password, Li Yu and Zhang Li immediately began to look for the target, Li Yu used the scope on the Baba sniper, and Zhang Li used the observation scope.

Zhang Li's observation ability was really powerful, and it only took a while to report: "Company commander, find the target, at three o'clock, under the big banyan tree." ”

Li Yu hurriedly moved the scope of the 88 sniper, and sure enough, the target was there.

"Measure the distance!" He hurriedly said.

"Understood!" Zhang Li replied.

There are many ways to calculate the shooting distance, and there are two common ones, one is to directly use the division in the optical sight to make a rough estimate, which is suitable for sniper rifles with less high accuracy; The other is an electronic rangefinder equipped with a high-precision sniper, which can directly measure the shooting distance.

The observation scope used in Zhang Li's hand is the most advanced type, with laser ranging function, and he quickly measured the distance: "Distance, 605 meters." ”

"Received, distance, 605, measure temperature, wind speed, humidity."

"Understood!"

The Type 88 sniper rifle needs to make corresponding tight position adjustments according to the firing table under different meteorological conditions. Each sniper rifle has its own shooting table for different environments, and the development of the shooting table requires a lot of calculations and tests, and the process is extremely complex. When it comes to actual use, snipers can look up the table and calculate, but this is also a technical job, and it is impossible to do it without training.

Zhang Li hurriedly took out various instruments and began to measure.
