"It can only be tested, not guaranteed. Xie Kai replied with a wry smile.

This is Xiao Manzhi's answer to him, and he also answered Wang Guilin with this.

People are professionals.

Therefore, he can only do this for the answer, and there is no guarantee at all.

"What about the bullets? Is it a special warhead for testing?" When Wang Guilin came over, He Chao and Yang Bin came over with a twenty-five or six-year-old elite soldier.

They want to know if the modified gun is equipped with professional sniper cartridges.

"There are some special sniper shells, and more are testing the Type 53 machine gun heavy ammunition, only in this way can more data be obtained. Xie Kai said.

In order to obtain first-hand test data and a more comprehensive understanding of the overall performance of the gun, it is necessary to test it in this way, and then to build a data model and determine the modified scheme.

The domestic imitation of 79 snipers has done some experiments, and it will definitely not be too professional, and it may not be too much. Now that they are conducting further tests, it is natural that there will be no 404 firearms that are specially prepared for high-precision testing.

When Wang Guilin and He Chao and others came over, Xiao Manzhi had already completed the assembly of the second gun, and only ate after it was finished, and then began to assemble the third sniper rifle.

The location of the replacement parts for each gun is different.

The ordinary bullets used by the 79 sniper do not need to be prepared, and the number of Type 53 machine gun bullets in the domestic reserve is sufficient, but when the sniper uses it, it is impossible to directly use all the bullets.

The snipers brought by He Chao selected the bullets one by one in the box full of bullets.

"The size difference between mass-produced bullets shouldn't be big, right?" Xie Kai was puzzled.

The size of mass-produced things is almost the same, which is the advantage of special aircraft and special line production.

"Just because of mass production, the accuracy of the warhead will not be too good, especially machine gun bullets, which are not intended for accurate shooting in the first place. The role of the machine gun is to form a dense fire suppression, and the trajectory of the bullet does not need to be so accurate......" He Chao explained with a wry smile to Xie Kai, "So before our snipers train, they will select the bullets and try to ensure that the accuracy of each bullet is almost the same, so that we can better grasp the trajectory." ”

Xie Kai understood.

The weight of the bullet warhead is not large, but the tolerances are not small.

"The roundness of the warhead, as well as the surface finish, will affect the trajectory of the warhead. The same gun, the same sniper, is not guaranteed to hit the same position at the same distance. Yang Bin also explained.

The sniper chose from a box of tens of thousands of rounds of ammunition, and in the end he only selected a little more than a hundred that were usable for him.

It is simply difficult to see the difference between these bullets with the naked eye.

At least Xie Kai and the others can't do it.

"How many special bombs have been prepared?" He Chao asked.

"Three hundred rounds, a total of three batches, each batch has a different charge, and the warhead is slightly different. However, the roundness and tolerance of each batch of warheads are controlled within 0.005 mm, and the weight of each warhead is only within 0.1 grams. According to our theoretical analysis, within 400 meters, snipers are experienced and can shoot wherever they want. The error will not exceed two centimeters. Han Weidong said calmly, "Of course, it has to be a sniper who knows enough about the guns he uses." ”

The meaning of Han Weidong's words surprised Xie Kai.

At a distance of six hundred meters, the ballistic dispersion is only two centimeters?

Isn't that a bit too braggadocio?

Even the world's first-class firearms have a ballistic dispersion range of 100 yards, that is, a distance of about 91 meters, which is only within 3 centimeters.

"Four hundred meters, isn't this distance too close?" Wang Guilin looked at Han Weidong.

Han Weidong ignored him.

Xie Kai smiled bitterly, Wang Guilin didn't know what this meant for machining accuracy.

"It's time to go. After the sniper preparation was completed, He Chao reminded Wang Guilin.

The Dynamic Testing Laboratory of the Firearms Research Institute is located in the underground part.

Xie Kai has been in the workshop of the firearms station for so many days, and he has never been there.

When he followed the group down, he realized that it was similar to the environment of the indoor shooting range he had seen on TV.

The only difference is that the passage in front of each firing position in this shooting range is a narrow passage.

The lights inside were dim, and it was hard for the naked eye to see a target a hundred yards away.

"Take it. When Xie Kai was wondering how to get the test data, Wang Guilin handed him a pair of earplugs.

"So simple?" Xie Kai was speechless.

This must not burst the eardrum?

The sound of the sniper rifle itself is not small, and it is in a small basement.

The group stood behind the sniper, and now these management are not as advanced as those of later generations, and there are no auxiliary devices for testing or anything.

A few people could only hold binoculars behind the snipers to observe distant targets.

Xie Kai looked through the telescope and saw that the target in the distance was in the center of the wall, and the entire wall had latitude and longitude lines. Compared to the target used by the troops, this is a magnified square target.

At the same time that the snipers of the garrison regiment were ready, the test gunners of the firing position next to them were also ready.

"When you're ready, let's go our separate ways. Wang Guilin's eyes were directed towards the tester at the test position next to him.

Xie Kai saw his small movements, and the old guy was still a little uneasy.

If you don't feel at ease, why let them come?

There are many people in China who can do this.

"Bang!"

A gunshot rang out, causing everyone to hold up their binoculars and look at the target at the bottom of the passage.

"Missed?" Looking towards the position of the target, Xie Kai clearly saw in the telescope that the bullet hit the target next to the target, which was more than ten centimeters away from the middle red heart. "Is it because of the bad light?"

"Bang!"

The sniper adjusted his scope, corrected the close-up position, and started shooting again.

The bullet was close to the center of the heart, but it was still a few centimeters away.

After a pause, gunshots were heard again.

"Bang, bang, bang......" Then the dense gunfire began to sound rhythmically.

Even with earplugs plugged in his ears, Xie Kai's ears were a little uncomfortable.

The bullet hit the target 100 meters away, and few of them could hit the center of the heart, but it made a circle of dense bullet holes one or two centimeters around the center.

The telescope in Han Weidong's hand never moved.

"Change the position, change the special sniper shell. I don't know if it's been a long time, Xie Kai is bored, the sound of this gun keeps ringing, not as dense as a machine gun, and not as dense as an automatic rifle, whether it is a tester or a sniper next to him, they all shoot rhythmically, which makes people feel very uncomfortable to hear this sound.

Both of them lifted their guns and switched to the test position next to them.

In this position, the prepared magazines are filled with specially made special sniper bullets.

Soon, the gunfire rang out again, Xie Kai was bored, and found that in addition to the number of times the impact point could hit the red heart in the middle of the target, the position scattered around the red heart was much closer than the 53 machine gun bullets used before, and there was nothing else.

"The test gun work is inherently boring, and to determine the modification, it is not enough to just shoot like this. When our new gun comes out, in order to test various performance and service life, the impact of various environments on accuracy during use, etc., the tester has to shoot thousands of rounds every day, and they can't shoot ...... at will," Han Weidong explained to Xie Kai.

Xie Kai nodded.

He didn't know how to answer.

"Just test these guns like this?" Seeing that the other party didn't speak, Xie Kai asked.

"No, it's been tried here, and I've got to test it at the shooting range outside. After all, this is an improvement after the repair of the original old gun, and a lot of data cannot be tested......" Han Weidong shook his head and said.

His attitude towards Xie Kai has changed a lot, and Xie Kai knows that he has explained so much to himself, it should be for the sake of funding and project progress.

"Our goal is to produce the best sniper rifle we can achieve, and the time it takes, the trials that need to be done, must be less. Xie Kai replied to Han Weidong with this. "Funding or something, since the base is engaged in this project, it will definitely not be less than a point, of course, we have to see the results and progress!"

Xie Kai didn't say that he had to wait until the accuracy was acceptable.

That would be endless.

The 79 snipers were originally in the army, and they were provided to the snipers of the special operations team of the garrison regiment, so they naturally had to supply them with new guns.

"As long as the accuracy can be improved, and we have tested it on our side, we will provide it to the garrison for further testing and obtain data for further improvement. Seeing Han Weidong looking at him, Xie Kai said what he thought.

Soon, the group came out of the firearms research institute, and the subordinates were more than four o'clock, and there was still the sun outside, but there was no feeling of warmth.

Xie Kai didn't bother to follow to the shooting range.

He's just watching the fun.

The sniper lay on the ground, constantly firing at targets hundreds of meters away, and he was bored watching from the sidelines.

If it weren't for the test data, he offered to shoot a few shots, and it wouldn't be a problem.

"After testing, the modified gun is equipped with special sniper shells, and within a range of 600 meters, the snipers of the garrison regiment can almost point where to shoot!"

At this time, Xiao Manzhi had completed the assembly of the third sniper rifle.

"The performance has improved a lot!" Xie Kai looked surprised.

"Not only the shooting performance, but also the recoil has been reduced a lot, especially the current scope, which can see more clearly than the original and provide higher accuracy!" He Chao said.

"Oh!" Xiao Manzhi just sighed at these.

"When the new guns made on our side come out, the scope will be modified a little more, and the new guns will perform better. Han Weiguo also said calmly.

Xie Kai was also impressed by how calm they were, and said to He Chao, "Commander He, you can use those guns first, and then give them to you for trial production when our new guns are trial-produced." ”

"How much does such a gun cost?" He Chao asked with some apprehension.
