After Hu Dajun changed jobs, he still liked work related to shooting, so he also asked to come to the military factory of Jiang University of Technology.

I started out as a technician in the workshop. Later, with this gun shooting experimental range, he also came here and became the administrator of the shooting range.

Because Zhao Zhongyao is very famous in Jiang Gong University, after arriving at the Jiang Gong University military factory, he is also very famous, before, Zhao Zhongyao designed tanks and armored vehicles, so that the workers and technicians in the Jiang Gong University military factory have known this chief engineer with outstanding talent, but also approachable.

Zhao Zhongyao has always liked to stay with the workers in the workshop, not only often help them work, but also care about their lives!

Hu Dajun is the same, of course he also knows Zhao Zhongyao.

"Yo! It's Director Zhao! Why did you come to the shooting range!" Hu Dajun looked at Zhao Zhongyao and then at Sun Guowei, but he didn't know Sun Guowei, so he only said hello to Zhao Zhongyao.

"Lao Hu, that's the case, let me introduce you, this is Division Commander Sun, who was the division commander of the army before, and has just transferred to our military factory, and is now a gunsmith.

We've both developed a gun, and now we want to do a shooting test here, so you can give us some bullets!"

Zhao Zhongyao saw that Hu Dajun didn't know Sun Guowei, but just looked at the two of them curiously, so he first introduced Sun Guowei's situation to him.

"Oh! It's a division commander who has changed jobs! Hello, Master Sun. Hu Dajun heard that Sun Guowei was a division-level cadre who had been transferred to another job, so he hurriedly came over and shook Sun Guowei's hand.

"Hello, I'm Sun Guowei. Sun Guowei also smiled and said hello to Hu Dajun. "Okay, I'll give you 10 rounds of ammunition for each of you! I'm sorry, Director Wu has a rule that you can only give 10 rounds of ammunition for each test shot. ”

Hu Dajun looked at Zhao Zhongyao and Sun Guowei with some embarrassment.

"That's enough, let's just test the accuracy of the guns. Ten rounds is enough. Zhao Zhongyao didn't want to say that he wanted to compete with Sun Guowei to see whose gun was better! He just told Hu Dajun that he was trying to test the shooting accuracy of the newly designed gun.

"Okay, I'll load your guns. Hu Dajun, after speaking, took the guns of Zhao Zhongyao and Sun Guowei, and loaded twenty rounds of ammunition into the magazines of the two guns.

After it was installed, it was handed to Zhao Zhongyao and Sun Guowei. Then he said: "Director Zhao, Master Sun, you two see if there are ten bullets in it." ”

"Old Hu. Can we still not believe you!" Zhao Zhongyao said, patting Hu Dajun's shoulder and laughing.

"Yes, old Hu! It doesn't matter if it's ten bullets or not! I only need one bullet for this gun, because I can shoot ten rings with only one shot. Sun Guowei was very arrogant and bragged in front of Hu Dajun and Zhao Zhongyao.

"Okay, old grandson, you don't have to blow here, let's go to the shooting range together and try it out!"

Since Sun Guowei said this big thing in front of Lao Hu. Zhao Zhongyao was not polite, and directly said that he would go to the shooting range with Sun Guowei to try it out.

"Okay, Director Zhao and Master Sun. It seems that the two of you want to see who has developed a gun with high shooting accuracy! Okay, then I will personally come to be a target reporter for you!"

As soon as Hu Dajun heard the tone of Zhao Zhongyao and Sun Guowei, he knew that the two of them wanted to see who had developed the better gun! He said he would report the two of them personally!

"Okay, that's hard work for you, Lao Hu. Zhao Zhongyao looked at Lao Hu politely.

"It's okay, I'm just idle here all day, it's okay to move!" Hu Dajun said. He walked out of the office with two targets made of paper. Walk towards the target trench not far away.

Zhao Zhongyao and Sun Guowei looked at each other, and they were ready before the two target platforms.

Both men started the shooting competition in the simplest lying position.

"Bang bang!" two gunshots rang out in the empty range. A flock of small birds on a large tree nearby. When they heard the gunshots, they all shook their wings and flew away.

"Director Zhao, Ten Rings. Master Sun, Eighth Ring. After the fight, Lao Hu came out of the trench and said loudly to Zhao Zhongyao and Sun Guowei.

"How about it, Master Sun, your gun is not as good as mine!" Zhao Zhongyao heard that he had ten rings with the first shot, so he smiled happily at Sun Guowei beside him.

"The first shot, what is it! There are still nine bullets!" Sun Guowei said unconvinced when he saw that his first shot was not as good as Zhao Zhongyao.

"Okay, let's hurry up and shoot the remaining nine bullets!" After Zhao Zhongyao finished speaking, he grabbed the trigger again, 'Bang Bang Bang-', and finished the remaining nine bullets.

Sun Guowei saw that Zhao Zhongyao had finished all the bullets so quickly, and he simply finished the remaining nine bullets.

After that, I saw Hu Dajun coming out of the trench and coming to Zhao Zhongyao and Sun Guowei with two targets.

"Two leaders, this is your target shooting results, or you can see for yourself! I won't say anything more. Hu Dajun said, and put the two targets on the grass in front of Zhao Zhongyao and Sun Guowei.

Zhao Zhongyao and Sun Guowei quickly looked at their targets.

Zhao Zhongyao looked at it and smiled. As soon as Sun Guowei saw it, his face sank.

"Haha, Senior Commander Sun, what's the matter, isn't your gun inferior to mine! You only hit the fifty-sixth ring! And I hit the ninety-third ring! What else do you have to say, shouldn't you admit defeat!"

Zhao Zhongyao saw at a glance that the bullseye of his target had been penetrated by his bullets. There were several bullets, all of which passed through the center!

However, Sun Guowei's target only had one shot through the center, and the rest of the bullets were all missed. It's all between the 5th and 6th rings. Another bullet may have missed the target, leaving no bullet holes in the target at all.

"Xiao Zhao! Why is the gun you developed so good! And why is the gun I developed so bad!" Now Sun Guowei has to admire Zhao Zhongyao. The facts are already in front of him, and the gun he made is not as good as Zhao Zhongyao.

"Master Sun, if you let me see your gun, I'll know what's going on. ”

Zhao Zhongyao said, and took the gun in Sun Guowei's hand.

"Senior Commander Sun, there is no rifling in the barrel of your gun! How can this be accurate!" Zhao Zhongyao looked at the inside of the barrel of the rifle developed by Sun Guowei. It's very smooth. There is no rifling at all, it is a slippery gun.

"Oh, so to speak, do you have rifling in the barrel!" Sun Guowei listened to Zhao Zhongyao's words, and quickly took his gun and looked at it.

After he looked at it, he realized that there were circles of rifling in the barrel developed by Zhao Zhongyao. And not smooth.

"Xiao Zhao! What is the purpose of these riflings? Is it because of this rifling that your gun is more accurate than mine?"

"Yes, there's a big difference between rifling in the barrel and not rifling. The purpose of rifling is to make the bullet rotate forward as it flies out of the barrel. And not the form does not advance. Zhao Zhongyao handed the gun to Sun Guowei.

"Spinning forward, how useful is this!" Sun Guowei didn't seem to be able to understand Zhao Zhongyao's words!

"Haha, you don't understand this! The bullet can keep the direction of movement as it rotates forward. Without rotating, it is easy to change direction, for example, if there is wind, it may affect the direction of the bullet. Sometimes the wind is so strong that it can even make a bullet flip in the air! How can such a bullet hit accurately!"

In the past few days, Zhao Zhongyao has also read a lot of books on firearms development, and he already has a good understanding of the various properties of guns.

At least on the point that rifling on a rifle can guarantee the speed of the bullet than without rifling. He already knew it before he was alive.

Now the guns he has developed, first of all, have made great changes in this regard.

The rifle went from rifled to rifled, which can be said to be a major improvement in the history of rifle development. It was a qualitative leap in the accuracy of the rifle's shooting.

After that, it didn't matter whether it was guns, or artillery. In the design of the barrel and barrel, most of them use a rifled structure.

"Oh. No wonder the bullets from my guns always deviate from the bull's-eye! It turns out that there is no rifling in the barrel of my gun, so I can't keep the bullets in the direction of their progress!"

After listening to Zhao Zhongyao's explanation, Sun Guowei understood what was going on.

"That's right. Division Commander Sun, this is a matter that you should pay attention to when developing guns in the future! Guns without rifling will soon be eliminated with rifled guns!" Zhao Zhongyao knows that in this parallel world, due to backward science and technology, many guns in the army are still in the era of 'smoothbore guns.'

And he wants to improve the guns of this era, so that the rifle will transition from a 'smoothbore gun' to a 'rifled gun'. Make yourself a master of firearms that changes the history of firearms.

"Xiao Zhao!ah, no! Director Zhao, I'm sorry, I looked down on you before. I don't think you're anything remarkable. Especially when it comes to gun development, you're definitely not as good as me.

But once again, it turned out that I was wrong. You really are a genius. Even when it comes to gun development, you're much smarter than I am. From now on, I will be your deputy! Let's work together to develop the most advanced guns of this era!"

Sun Guowei listened to Zhao Zhongyao's patient explanation to him, and he understood that he was really inferior to Zhao Zhongyao. Not to mention in terms of other weapons and equipment. Even in terms of gun development, which is his best, he is not as good as Zhao Zhongyao!

This time, Sun Guowei really admired Zhao Zhongyao, and admitted that he had lost in person. I also want to be Zhao Zhongyao's deputy!

"Master Sun, you are so polite. What we lack most in China is a gunsmith like you! Okay, let's work together to develop more advanced guns in the future!" Zhao Zhongyao saw Sun Guowei apologize to himself and admit that he had lost, and he was also sincerely happy!

The two took the target to the management office of the shooting range and handed it to Hu Dajun, and then returned to their respective offices together.

After Sun Guowei returned to his office, he called Yao Hongjun over again.

Yao Hongjun also heard that Sun Guowei went to compete with Zhao Zhongyao for the accuracy of the gun.

He now sees Sun Guowei calling himself. I thought, it must be Sun Guowei who won, Zhao Zhongyao!

"Old Sun, what's the matter, did you win Zhao Zhongyao!" Yao Hongjun looked at Sun Guowei happily.

"Win a bird! Sun Guowei sat on the sofa angrily, took out a cigarette from his pocket, and handed it to Yao Hongjun.

Yao Hongjun took the cigarette, took out the lighter, lit Sun Guowei's cigarette first, and then lit his own cigarette.

Both of them took a big sip together. He spat out another puff of smoke from his mouth. "Old Sun! Did you admit defeat like this! Did you obey Zhao Zhongyao's kid like this!" Yao Hongjun listened to Sun Guowei's words, and he was still a little unconvinced!

"Old Yao, are we just inferior to Zhao Zhongyao! We are not as good as others in the development of guns, so can you do it if you are not convinced?" Sun Guowei looked at Yao Hongjun and said.

"Old Sun! What do you say about Zhao Zhongyao's gun? Isn't our gun even more powerful than his gun!" Yao Hongjun knew that the gun he and Sun Guowei developed was very powerful and had a long range, so how could it be inferior to the gun developed by Zhao Zhongyao!

"Lao Sun! What is the use of the power of the gun! Shooting at the target is more accurate than shooting! No matter how powerful the gun is, it is useless!" Lao Sun looked at Yao Hongjun helplessly and said.

"Lao Sun! Then why is the shooting accuracy of our guns not as good as that of Zhao Zhongyao!" Yao Hongjun couldn't figure it out, the guns he developed were not bad! How could they be inferior to the guns developed by Zhao Zhongyao in terms of shooting accuracy!

"Old Yao! That kid from Zhao Zhongyao is really very smart! He actually designed some spiral-shaped rifling wires in the barrel. Sun Guowei looked at Yao Hongjun and said.

"What, spiral-shaped rifling, what's the use of that!" Yao Hongjun didn't know about rifling in the barrel of a gun! After listening to Sun Guowei's words, he asked strangely.

"Old Yao! You don't know, rifling in the barrel is very useful! It can ensure that after the bullet is fired out of the barrel, it will not deflect in the direction! And without rifling, it cannot be guaranteed that the bullet will remain in one direction when it is fired out of the barrel. Not only can they not maintain one direction, but they may also be affected by the wind speed and turn their heels in the air! You say, how can such a gun hit accurately! When I was shooting with Zhao Zhongyao this time, the 10 rounds of bullets hit 93 rings, while my 10 rounds of bullets only hit 56 rings! Among them, one bullet missed the target!

Sun Guowei looked at Yao Hongjun and said that he had just competed with Zhao Zhongyao on the shooting range for the accuracy of the gun. (To be continued......)
