Chapter 87 Type [-] sniper rifle, shooting table questions (for further reading)

[The beginning of the last chapter has nearly [-] words and has not been copied. No one mentioned it. It affects everyone's experience. Yesterday, the computer flooded too quickly. You can look back.Of course it's not too important]

Geng Jun led the crowd to the sniper range hundreds of meters away from the rifle range.

Like last time, the sniper range is not a flat area, but a Gobi area with shelters and slopes.

However, the last time I went there was calm and calm, but this time Li Xiu could feel the wind blowing on his face.

The shooting range has a slope as a whole, mainly to get close to actual combat.

At this time, Geng Jun walked up to Li Xiu, and casually chatted: "You performed very well this time, and the fourth company of the sharpshooter will naturally give you a reward. You probably haven't used the Type [-] sniper rifle yet."

Li Xiu was taken aback, but Geng Jun laughed: "This time I have the opportunity to try it, it is better than the eighty-eight style."

Li Xiu was stunned for a moment, and then a look of excitement appeared on his face.

He has already played well with the gun today, with more than 900 rounds of ammunition, which many soldiers can't shoot so much in three years.

It's nothing more than being able to fire so many bullets. I didn't expect there to be other rewards.

The Type [-] sniper rifle is actually much easier to use than the Type [-] sniper rifle.

Although there are many shortcomings.But the overall advantage is quite obvious.

The Type [-] sniper rifle is modeled on the SVD sniper rifle of the former White Bear Country Dragunov. It is mainly used as an individual weapon for border posts and infantry snipers.

As the frontier defense company, the fourth company of sharpshooters is naturally equipped.

The Type 200 sniper rifle is actually not in the same category as the Type 300 sniper rifle. The Type 200 sniper rifle does not particularly pursue accuracy. It is said to be a sniper rifle, but in fact its function is only to precisely kill targets within the combat range of the rifle.The key targets are within [-] meters, [-] meters, or even within [-] meters.

After all, the 5.8-type bullet has a caliber of [-]mm, and the trajectory of the bullet is unstable when performing long-distance sniping.

The Type 7.62 is a 5.8mm machine gun bullet. Although it is not equipped with high-precision sniper bullets due to economic problems, it is much more stable and powerful than the [-]mm.

Therefore, compared with the [-]-type sniper rifle, the [-]-type sniper rifle mainly kills important single targets at medium and long distances.

This thing is a sniper rifle in the true sense. Our army snipers even used it to set a sniper record of 300 and [-] meters.

The effective range is 1000 meters, and the limit range is 600 meters.

Of course, because there is no special development of high-precision sniper bombs, the limit range only exists in theory.

Several recruits didn't know why, but they all saw Li Xiu and Geng Jun walking side by side, and Geng Jun didn't put on airs at all.

This is the rhythm of hooking shoulders with the company commander.

"Come on, this is Baba Sniper, this is a scope with adjustable white light."

When they arrived at the shooting range, Geng Jun first explained the Eighty-eight Form to the other seven recruits. Li Xiu had already understood it, but he continued to listen to it.

At this time, Wang Tie looked at the shooting range, stretched out his hand to feel the downwind direction, shook his head and said, "I'm not lucky today, the wind is a bit strong."

His unique skill can no longer be performed.

Wang Tie felt very sorry.

900 meters suspended air balloon target.

very handsome.He also likes to show his skills to recruits.

But this time it probably won't work.

After all, a floating balloon target is equivalent to a moving target, and the 5.8 sniper is a [-]mm caliber bullet, which is too much affected by the outside world and is very difficult.

It's okay in a windless environment, but with a little wind, his error rate will increase infinitely.

Moreover, in a windy environment, the balloons also fly randomly.

"Li Xiu, do you remember the shooting table of the [-]-style sniper rifle?" Suddenly, Wang Tie thought of something and asked Li Xiu.

Anyway, Li Xiu understands what the company commander is talking about now, so listening is a bit of a waste of time.

Simply chat with Li Xiu for a while.

"remember."

"Okay, let me ask you a few questions." Wang Tie said, pulling Li Xiu aside.

Of course Li Xiu remembered the shot table.

[Sniper Theory] Although Li Xiu has not fully developed his skills yet, to be honest, speaking of theory, he is much stronger than Wang Tie.

It's okay to throw ten blocks.

Not only did he memorize the shooting table of the [-]-style sniper rifle, but he also remembered the shooting table of all sniper rifles very clearly.

Including sniper rifles equipped by foreign troops.

Depending on the performance of the guns, their bullet models, and the shooting tables of the firearms, there is a huge gap.

Moreover, in the face of complex terrain environments, the shooting table is often not accurate enough.

"Okay, let me test you?" Wang Tie asked with a smile.

Li Xiu nodded.

"For a distance of 300 meters, the distance correction amount is for every 10 degrees increase or decrease in air temperature and charge temperature."

"7 meters." Li Xiu replied without hesitation.

"Yes. It's still 300 meters away." Wang Tie nodded and said, "For every 10 mmHg increase or decrease in atmospheric pressure, the height correction amount is..."

"It's zero on the shooting chart." Li Xiu answered, thought for a while, and added, "However, it should be around 5mm based on the actual combat data."

"You really forget it?" Wang Tie was surprised, but he could understand it after thinking about it.

After all, Li Xiu was admitted to Peking University, so it would be no problem to memorize a few formulas and calculate the data.The subject of sniping requires high precision, so it doesn't matter how true it is.

"The amount of calculation is not too much... I just tried it." Li Xiu smiled and didn't say much.

These calculations are not large. If it is really complicated, there will be no sniper with a calculator on the spot.

"Awesome, I can't understand those anyway." Wang Tie gave a thumbs up and asked the last question.

"What about the direction correction, horizontal and wind, and his secret position and correction at 800 meters?"

"2.80 and 3.5."

Wang Tie nodded again.

It seems that Li Xiu has remembered everything.

Moreover, judging by Li Xiu's reaction speed, he remembered it very skillfully.

At this time, Wang Tie smiled, took out a small wind measuring instrument, and read it.

"Today, the wind speed is about level four, and the temperature is about one degree below zero."

"In a moment, you can try the Eighty-Eight Form first, and I'll see how you apply it to the shooting table."

"Yes!" Li Xiu immediately responded loudly.

Wind speed and temperature are the two initial variables that most affect mechanical properties.

The wind speed is well understood. The temperature will affect the combustion of the propellant in the bullet, which in turn affects the initial velocity of the bullet. Strictly speaking, the temperature has a greater impact than the wind speed.

This is also the reason why some sharpshooters' shooting accuracy is affected in the alpine environment.

Of course, although the temperature has a great influence, it is easier to correct the deviation.

The most difficult thing is the wind speed, that is, the wind force.

Wind speed is also difficult to measure, especially in complex terrain.

For example, in some novels, the protagonist licks his finger with his tongue, or picks up a piece of dogtail grass, and then he can feel the wind speed, temperature and other external factors, and then calculate, and then correct the deviation, and he can hit every target... Actually, it’s not very rigorous.Although the rough test can be measured in this way, it is impossible to hit every shot.

It's not about the upper limit of gun accuracy.

But the calculation method is wrong.

The wind speed is greatly affected by the terrain. There is generally a difference between the wind speed at the sniper's position and the wind speed in the bullet's flight range.

The wind speed at the location of the sniper has little effect on the accuracy of the sniper. What the sniper needs to estimate is the wind speed in the sniper range of the bullet. Unless it is located in the Great Plains, measuring the wind speed at the location of the sniper is helpful to the accuracy of the sniper. But it is impossible to hit every shot.

"Li Xiu, come on, you use the [-]-style to fire a shot first, and show them a few recruits."

At this time, Geng Jun called out to Li Xiu.

"Yes."

Li Xiu shouted.

"Be careful, it's windy today, you need to correct it yourself, see if you have learned what I said last time."

Geng Jun reminded.

It was a coincidence for Li Xiu last time, the wind happened to be very small, so it had almost no effect.

This time is different.

It's windy.

Moreover, because the sniper range has a certain slope, it will also affect the wind speed, so even if it is the same 600-meter target, it is more complicated than last time.
