Chapter 1081 The fully upgraded bolt
. Can this pistol actually shoot so fast and so accurately?
Although the target is only 20 meters away, the shooting speed and hit rate are simply invincible!
"Chief, chief, please let me do it again, I want to try it too!"
Seeing Luo Chong's amazing operation, Qubing immediately asked for another round. Luo Chong was about to reload, so he gave him the position.
Bang bang bang bang——
Qubing had a great time shooting there, and the guards around him were envious. They all wished they could replace him and shoot two rounds for fun.
Luo Chong had already reloaded a round of bullets at this time, but he did not continue shooting. Instead, he turned off the safety and put the gun on his belt, and picked up the only two copycat Browning 1911s next to him.
This pistol is a large-caliber, high-powered pistol. It uses a single-row magazine and can only hold seven rounds at a time. The automatic mode is also a short-recoil barrel mode, but the structure of the slide is more complicated than that of the Beretta 92F. You need to twist the muzzle to disassemble the slide.
After Qubing finished shooting the second round, Luo Chong demonstrated the disassembly and assembly steps of the 1911 to him again, then loaded it with bullets and came to the shooting position again.
Bang, bang, bang, bang, bang————
a series of gunshots rang out, and the seven bullets were quickly fired by Luo Chong. The round steel plate target 20 meters away was also swung by Luo Chong, full of bullet marks.
Qubing was also very curious. He picked up another gun and fired several shots in a row until he ran out of bullets, then shook his head and complained.
"This gun is not good. There are too few bullets, and the recoil is also greater than the previous one. It made my wrist numb. Chief, since we have the ability to make the gun just now, why do we need to make another one like this?" Qubing asked in confusion.
In fact, it is normal for people who are not familiar with these two firearms to have such doubts.
The two pistols have the same range, one has a capacity of 15 rounds, and the other has a capacity of 7 rounds, which is less than half of the previous one. In addition, the recoil of the 7-round pistol is large, the structure of the gun is relatively complex, and the functions are not as many as the 15-round pistol. It is not cost-effective no matter how you look at it.
But since Luo Chong made this choice, he certainly had his own considerations. Luo Chong was seen playing with the two pistols and said.
"It's just right that you don't like this gun, because this type of pistol was not originally prepared for you."
"Ah?! It's not prepared for us? Then who will use it? Oh, I see, are you going to equip other guards with this kind of pistol?" Qu Bing was surprised at first, and then immediately analyzed it.
But it's not wrong for him to think so. After all, there was a precedent before. The Shen Ce Guards were all equipped with semi-automatic rifles, and Luo Chong also planned to replace bolt-action rifles for other troops, so the Shen Ce Guards' pistols should also be more advanced than other troops. Is this analysis correct?
But Luo Chong shook his head and explained.
"This type of pistol is not equipped to the army, but to the local government's prisons and constables. It is used when arresting criminals to prevent them from using swords to resist and injure others.
"Don't underestimate this type of pistol. Although it has a larger recoil, the caliber is also larger, and the bullet is more powerful. The biggest feature of this gun is its strong resistance ability. No matter how strong a man is, one shot can definitely knock him down.
"But the one with fifteen bullets is different. Even if it hits the body, it may not be able to knock him down with one shot, but the advantage is that its firepower is more sustained, and it has more bullets, which is more suitable for military use.
"And constables don't need so many bullets when arresting criminals. What they need is great power. When facing criminals holding swords, if the criminals resist, they can just knock them down with one shot.
"Because the needs of both parties are different, it is naturally impossible to use the same model."
Qubing nodded in agreement when he heard this. There is nothing wrong with using different firearms for different needs.
After everyone had simply tried the two types of pistols, it was almost noon. Lin Fei had someone prepare lunch and asked Dali to come and accompany them. A group of people had a simple lunch at the research institute. Because they had to take other firearms to the Shen Ce Wei military camp for comprehensive testing in the afternoon, no one drank at noon, for fear of drinking and delaying work.
After lunch, they took a simple rest. In the afternoon, Lin Fei found a carriage filled with firearms and ammunition that needed to be tested this time. The other researchers also followed on horseback, and everyone rushed back to the military camp.
Because there were many projects this time, it would take several days to carry out. When everyone arrived at the military camp, it was almost three o'clock in the afternoon. Because the time was short, Luo Chong directly asked them to start testing the new bolt-action rifle - the copycat version of 98K.
Because the soldiers of Shen Ce Wei used similar guns before, there was not much difference in changing to this one now. The changes were all small details, and the results could be tested quickly.
Therefore, since Luo Chong came to the military camp, the gunfire in the shooting range has never stopped, because the service life of the barrel needs to be tested. According to the design data, these sample guns can fire 10,000 rounds and still guarantee a certain degree of accuracy. Therefore, if you want to test the actual effect, you have to really fire 10,000 rounds.
Bang, bang, bang, bang.
A soldier kept pulling the bolt to shoot at the target in the distance, and there were people counting and delivering bullets beside him. After every 100 shots, they would change people and ask them to talk about their experience of using the new gun. After every 1,000 rounds, they would remove the bolt and do some simple maintenance. After every 2,000 rounds, they would not only maintain the bolt, but also the barrel. They would keep testing at this frequency throughout the afternoon.
For 10,000 rounds of bullets, a full 100 soldiers took turns to take the field, so that these soldiers also became familiar with the practical feeling of the improved rifle.
At the simulated trench not far from the shooting range, another group of soldiers were testing new guns, mainly testing the portability of the new guns, such as charging with the new guns, crossing obstacles, jumping over trenches, and moving back and forth quickly in the trenches with the guns. In this way, when the soldiers turned around in the trenches with the guns, if the gun body was too long, it would be easily stuck in the narrow trenches, and the new guns with shortened gun body length would not encounter this problem.
Another group of soldiers was assigned to another shooting range for live ammunition testing. The test items were not the durability and service life of the guns, but the reliability in various harsh environments.
For example, the gun body was soaked in sand to simulate the use in sandstorm weather; or water was poured on the gun body to simulate heavy rain weather; there was also a long-term soaking in river water to simulate the armed swimming of troops (swimming or crossing the river); the most stringent subject was the use in the swamp environment, which required the gun body to be soaked in mud, and then taken out and shot directly with water and mud to see if the gun could work properly.
Perhaps it was because the sample guns were carefully made, or perhaps molybdenum steel was really powerful, so there were no unacceptable problems in the test.
The results of the four environmental tests were relatively ideal. The improved bolt-action rifle had no problems in firing and use. As for whether it was accurate, this was not within the scope of the test.
After all, in the rain, and in the case of being covered with mud and river sand, sometimes the front sight and rear sight were covered with mud, and it was impossible to aim, so how accurate could you expect it to be?
In this case, as long as the bolt can be pulled open, bullets can be loaded, the bolt can be loaded, the safety can be turned on, and the trigger can be pulled, the gun can be used normally, then it is perfect. At least in actual use, there will be no major problems.
The current environmental test still lacks one last project, which is whether it can be used normally in an environment of dozens of degrees below zero in ice and snow weather.
Unfortunately, it is summer now, and even Heyuan County in the north is very hot now, and the Han tribe has no refrigeration equipment, so this project can only be skipped directly.
However, according to the performance of the standard rifle of the previous copycat version of G98 in the Northern Expedition, there is no problem, so the new rifle improved on this model will not be able to overcome the cold environment in the north.
On the other hand, the portability test of the improved rifle has also ended. It is easier to carry the new rifle for armed cross-country than the soldiers carrying the old rifle, because the weight is much lighter after the gun body is shortened.
In addition, in terms of shuttling back and forth in trenches, simulating battlefield charges, and armed crossing of jungles, it has shown better quality than the old gun.
For example, in terms of jungle shuttle, the new gun is shorter and not easy to be stuck by trees. The downward-curved bolt handle is not easy to get caught on branches, which is much better than the old gun.
After the portability and environmental tests are completed, only the bullet power and accuracy, as well as the firearm life test are left.
The life test cannot be completed in a short time, but the bullet power and accuracy are easier to test.
The way to test the power of the bullet is to shoot at the steel plate. At different distances, shoot at a three-millimeter thick steel plate target to see how many layers can be penetrated. Another difference is the difference between ordinary bullets and steel core armor-piercing bullets.
Ordinary bullets are copper-clad lead cores, while steel core armor-piercing bullets are copper-clad armor, and are filled with soft lead wrapped steel core three-in-one bullets. When the bullet's armor copper skin is flattened on the target surface, the steel core inside can continue to fly and penetrate thicker steel plate targets.
The cost of this bullet is not much more expensive, but the production process requires an extra step. Fortunately, the Han tribe does not need so many steel core armor-piercing bullets, because no enemy has so much armor that can threaten the power of the Han tribe, let alone steel armor, even wooden shields or leather armor are not many, so there is no need to worry about this problem.
The improved rifle still uses the shooting of the four right-handed rifling of the old gun. The only difference is that the twist is a little smaller than the old gun, which increases the rotation speed of the bullet after it leaves the barrel, so that the trajectory of the bullet can be lower, deeper and straighter. This is also a change made specifically to reduce the caliber of the bullet.
After this small improvement, although the barrel of the improved rifle is shortened by 15 centimeters, the flying bullet can still maintain the characteristic of not falling within 300 meters. In this way, no other changes are needed in the gun sights, and the steps of testing the trajectory and re-setting the shooting scale can be directly omitted.
Moreover, the penetration of the 7.62mm full-power rifle bullet has become stronger than the original 8mm bullet. In terms of power, it can be said that it has increased rather than decreased. In addition, because the diameter of the bullet cartridge has been reduced, the amount of powder has also been reduced accordingly, which has led to a corresponding reduction in recoil.
In general, the improved 7.62mm full-power bullet is stronger than the old model bullet in all aspects. I just don't know how effective it is when used on a machine gun. However, the number of bullets is limited, and it is almost dark, so Luo Chong did not ask to test the machine gun.
When the environmental adaptation, portability test, power and accuracy test were all tested and the results were obtained, the firearm life test on the other side was almost completed.
Continuously firing 10,000 rounds of bullets is something that the old guns dared not think of before. If the old guns fired 10,000 rounds of bullets, the rifling should have been smoothed long ago, and it would become a smoothbore gun. The bullets would lose the ability to rotate automatically, and the bullets fired would fly away without knowing where.
After firing 10,000 rounds of bullets, Luo Chong first had someone do maintenance on the gun, cleaned and wiped it thoroughly, and then applied gun oil to the parts. Finally, he removed the barrel and used a carbide lamp to shine a strong light on the inner wall of the barrel. He found that although the rifling inside was worn a lot, it could still be clearly observed with the naked eye. This shows that after firing 10,000 rounds, the wear of the barrel was not very serious and it was still worth continuing to use.
Now we just need to actually test the accuracy after 10,000 rounds to draw a final conclusion.
For the last round of accuracy testing, Qubing took the initiative to volunteer. Qubing personally did a maintenance on the gun, then loaded it with bullets and started shooting at the 300-meter human chest target, 350-meter target, 400-meter target, and then increased to 600-meter target.
If it is farther, it can also be shot, after all, it is a copycat 98K that can be used as a sniper rifle, but if it is farther, the target cannot be seen with the naked eye. If it is more than 600 meters away, unless the eyesight is abnormal, it can only be shot through the scope.
Starting from 300 meters, each target was shot with 10 bullets, a total of 100 rings, and the final score was determined based on the number of rings.
In order not to be affected by "personal" factors, such as who has better shooting skills, in addition to Qubing, Luo Chong randomly selected two other soldiers, and used the same gun to shoot again in the order that Qubing had just shot. Finally, the data of the three people were compared to get a more reliable result.
Finally, after testing, the improved bolt-action rifle, after 10,000 shots, was able to get an average score of more than 90 points in the 300-meter chest target test, indicating that at the distance of 300 meters, the wear of the barrel did not affect the initial velocity and trajectory of the bullet, and the bullet still flew out so flat.
As for the following 350 meters, 400 meters, 450 meters, 500 meters, and 600 meters, there was no obvious difference between the scores of the new gun and the old gun after shooting 10,000 rounds.
This result shows that the service life of the new gun is at least 10,000 rounds of bullets, and after shooting 10,000 rounds of bullets, the performance did not show a significant decline, and it is still worth using.
This one item alone saved the Han tribe an unknown amount of military expenses.
