Chapter 1082 There is a problem with this gun

After a series of test projects, the improved version of the bolt-action rifle was finally finalized. As for the model name of the new gun, Luo Chong considered it again and again and decided to continue the previous naming rules and call it "Standard Type II Rifle".

According to the naming conventions of firearms in the previous life, there are generally three ways. Either it is named after the inventor, such as Browning, Mauser, etc.; or it is named after the head of state, such as Zhongzheng Rifle; or it is named after the year in which the new gun is finalized, such as Type 56 and Type 81, but these naming methods are not suitable for the current Han tribe.

First of all, the actual "inventor" of the new gun is Luo Chong, so it can't be called Luo Chong type, right? Then there is the head of state's name, Luo Chong does not have a word like "Zhongzheng", and finally if it is finalized by year, then this gun should be called "Da Ming Year 2 Rifle", which sounds weird, so it is better to sort it directly according to Standard One and Standard Two.

Luo Chong personally defined it as a "cross-generational nomenclature", which means the replacement of firearms. In this way, you can tell which generation of rifles this is by just hearing the name.

After a night's rest in the barracks, the test continued the next day. Because there was plenty of time today, Luo Chong decided to test the remaining two pistols, as well as the semi-automatic rifle and machine gun together, and strive to complete the test within one day. If they passed, they would be finalized, and if they failed

, they would continue to be modified. After breakfast in the morning, Luo Chong asked Qu Bing to start arranging the test of the pistol. They had already conducted preliminary tests on the two pistols at the research institute yesterday. There was no problem with shooting. Now it depends on whether the various performances can meet the standards. The

test of the pistol is still similar to the previous standard type II rifle, which includes accuracy test, bullet power test, environmental test, and firearm life durability test.

As for the portability test, it was omitted.

Why does a pistol need to be tested for portability? How can such a small thing not be carried?

According to the standard proposed by Luo Chong, the barrel of a pistol made of molybdenum steel must at least withstand 10,000 shots without any significant performance degradation. The test process is similar to yesterday, with a change of personnel for every 100 shots, simple maintenance for every 1,000 shots, and detailed maintenance for every 2,000 shots. After firing 10,000 rounds, the accuracy is re-tested.

This work is actually quite simple, except that it takes a long time to fire 10,000 rounds, and in order to reduce the interference of human factors as much as possible, a large number of manpower must be mobilized to participate, but these are not a problem for the Han tribe.

Qubing directly handed the test of the pistol to the battalion commander of the first battalion, and he followed Luo Chong closely, because this kid knew that today's semi-automatic rifles and machine guns were the highlights, and he had already fired the pistols himself yesterday.

"Chief, when we test this semi-automatic rifle and machine gun, do we need to use tracer bullets to observe the trajectory?" Qubing reminded him.

"If you want to see the trajectory, you definitely need tracer bullets. By the way, Lin Fei, did you bring tracer bullets?" Luo Chong turned his head and looked at Lin Fei beside him. The preparation of the weapons and ammunition was all done by him. Who else could he ask?

Lin Fei was a little embarrassed when he heard this. He didn't really prepare many tracer bullets.

"Replying to the leader, the production of these new types of bullets is not large, and the number of special bullets like tracer bullets is even smaller. We have prepared some, but not too many. There are only 1,000 tracer bullets for semi-automatic rifles and 5,000 tracer bullets for machine guns. I wonder if it is enough?" Lin Fei answered carefully.

Luo Chong quickly calculated in his mind that the biggest problem with the semi-automatic rifle test is the life test, which is also the life standard of 10,000 rounds of bullets. These 10,000 rounds are to cause wear and tear on the gun. It doesn't matter whether it can hit the target or not, as long as it is fired, so there is no need to use expensive tracer bullets for testing. After firing 10,000 rounds, it is not too late to use tracer bullets when retesting the trajectory and accuracy.

As for machine guns, it was even more unnecessary. I had never heard of a machine gun that fired all tracer bullets. Machine guns sometimes needed to use tracer bullets on the battlefield, but that was to indicate targets to their own comrades, so that they could use the bright trajectory to tell their comrades where the enemy was.

But even so, when machine guns used tracer bullets, they would load a tracer bullet after a few ordinary bullets, such as three plus one, or four plus one, four normal bullets plus one tracer bullet. This way of loading was enough to point to the target.

According to the standard of 250 rounds of bullets in one ammunition belt, the four plus one loading method means that one ammunition belt needs 50 tracer bullets. Lin Fei brought 5,000 rounds, which can fill 100 250 ammunition belts, which is enough for use.

"Well, it's almost enough if we use it sparingly. Let's have someone load the bullets. First, get some ordinary bullet chains, all in the length of 250 rounds each, so that we can count more easily. Then get ten tracer bullet chains. The loading method is four plus one, that is, four ordinary bullets plus one tracer bullet, and then four ordinary bullets plus one tracer bullet. Just fill the chains in this order. Qubing, you will arrange the soldiers to load the bullets. Just don't mess up the order." Luo Chong nodded and arranged for the two.

"Yes!" The two bowed and agreed at the same time, and then started to make their own arrangements.

After waiting for a while, when the two came back, Qubing asked again.

"Chief, how do we test the machine gun? I've already told the second battalion commander about the semi-automatic rifle and asked them to test it the same way they tested the standard Type II rifle yesterday. There shouldn't be any big problems. The only thing left is the test of the machine gun."

Luo Chong nodded and said, "Let's get the ammunition ready first. We'll use 250-round belts and 200-round medium-length belts for this test. Let's use the 250-round belt first. Four belts will be 1,000 rounds, and 40 belts will be 10,000 rounds, so we can count them.

"As for the test items, it's similar to the rifles. The first is the durability test of the firearm's life, but let's test this later because we only have this one sample gun now. If it breaks, we can't test the others."

The two nodded when they heard this, and Qubing asked, "Then let's test portability first? Or precision shooting? Or simulated environment test? ”

“First test the portability, including armed marching with firearms on the back, rapid trench maneuvers, and jungle crossing, which are still the same three items; after testing the portability, test the precision shooting. Lin Fei, you will assist from the side. When measuring the accuracy, you must use the tracer bullet belt to mark the trajectory.

“Also, the machine gun’s precision shooting test should start from 400 meters, and then increase by one level every 100 meters until it reaches 1,000 meters!

“In addition, there is also a hit rate standard for machine gun precision shooting. Machine guns do not require single-shot precision shooting, so as long as the burst and sweeping shots are accurate, there will be no problem.

“Take burst shooting as an example. Each time you pull the trigger, let go and control the number of bullets fired to more than three and less than five. This is a burst.

"For strafing, there must be at least ten human-shaped chest targets placed side by side at the same time. The shooter is required to use fifty bullets and shoot ten targets side by side in one breath. The passing standard is that each of the ten human-shaped chest targets must be hit by at least one bullet. It doesn't matter how many rings are hit, as long as they can hit the target.

"That is to say, if ten out of fifty hit, it is qualified, twenty hits is good, thirty hits is excellent, and thirty or more hits are special machine gunners. You should train such people well in the future."

While introducing the accuracy standards of machine guns, Luo Chong told Qubing about future training. Qubing also nodded repeatedly while listening, indicating that he had learned new knowledge.

In the past, we only knew how to evaluate the accuracy of rifles, but now the leader has also put forward standards for machine guns.

And from the standards proposed by Luo Chong, we can see how he uses machine guns as a weapon.

Machine guns are used for fire suppression. There is no need to use them for single shots. If you want to shoot, just shoot continuously. If there are one or two, or less than three targets, just shoot in short bursts. It was a series of bangs. If there were more than ten people in a group, he would use fifty bullets to kill them directly. One out of five shots would be considered qualified, which means Luo Chong didn't care about bullets at all.

If he could only hit one out of five shots with a rifle, he would probably be beaten to death by the leader.

You loser! How can you waste bullets like this? !

But machine guns won't.

However, thinking of this, Qu Bing thought of a new question, "Leader, the burst shooting you just mentioned, is there any corresponding standard for use in any situation? If there is a standard, it will also facilitate our later training!"

Luo Chong thought about it and it seemed to be true. He forgot to mention this question just now.

"There is a standard. I forgot to say just now that there are three shooting methods for machine guns, namely short burst shooting of three to five bullets, and the target of the shooting is a combat group of less than three people; if there is a target between three and six people, use long burst shooting, which is a burst shooting of ten bullets at a time, not more than ten rounds of continuous shooting.

"After long and short bursts, the only thing left is continuous fire, which is to carry out continuous strafing at clustered targets of more than six people. But you can't hold the trigger tightly and don't let go. You still have to control the ammunition consumption rate. Try not to fire meaningless blanks. At the very least, you have to gain something from every shooting. Even if you fire fifty rounds at a time, as long as you hit one person, you won't lose!

"Also, the theoretical rate of fire of our machine gun is about 700 rounds per minute, but I don't want you to really waste bullets like this. Taking the 200-round ammunition belt as an example, try to control the ammunition consumption rate to 200 rounds per minute. It is already a luxury to change a belt for one minute. Did you remember?" "

Luo Chong kept teaching the techniques of using the machine gun. Qu Bing and the third battalion commander were also listening nearby and nodding their heads like chicks pecking at rice. It turned out that there were so many tricks to using a machine gun.

Portability test, accuracy test, and then environmental test.

There was no essential difference in the previous tests except that the standards had changed. However, this simulated environmental test really needed to be changed.

Because Luo Chong knew a big problem with machine guns like this.

The canvas ammunition belt is afraid of moisture!

When the canvas ammunition belt is wet, it is easy to cause jams.

So you often see in war movies that there is always a belt puller next to the machine gunner.

Although the ammunition hand is originally a belt puller, it depends on the situation. If it is a sunny and dry environment, just install the belt and there is no need for another one. But if the ammunition chain is soaked by water, you have to pull it.

In World War II, machine guns that used canvas ammunition chains, such as Maxim, G42 and other machine guns, almost all had this problem.

Modern metal scatterable ammunition chains do not need to worry about this problem, because moisture will not have much impact on metal. Even if there is an impact, it will not appear in a short time, such as rust.

The Han tribe is not yet luxurious enough to use metal scatterable ammunition chains. You know, after using such ammunition chains, there is basically no possibility of recycling and reuse. It is almost a metal consumable. Instead of this, it is more cost-effective to use reusable canvas ammunition chains.

So in order to avoid such troubles, Luo Chong also explained to them that canvas ammunition chains are more It is strong, but it is made of cloth. As long as it is cloth, it will be afraid of moisture, so the tests should be conducted separately.

For example, in the immersion test, you can soak the machine gun in water or mud, but don’t put the ammunition belt in. After taking the gun out, you have to shake it to clean off most of the water, and then install the ammunition belt to shoot.

No one had any objection to Luo Chong’s suggestion. Everyone understood it, because machine guns are powerful, and they can fire continuously, and there are so many parts inside.

What’s wrong with such a powerful weapon being a little more delicate than a rifle?

Shouldn’t a powerful weapon like a machine gun be treated like a treasure?

Who is willing to throw a machine gun in the mud and ruin it? !

Qubing said that he would definitely not be able to kill him.

The last subject is durability, which is a life test, but The testing methods for machine guns and rifles are different. Rifles fire slowly, so the barrel will not overheat, but machine guns will. If the barrel is not replaced, the barrel will turn red.

So Luo Chong arranged to use two barrels and use them in rotation. Each barrel must fire 10,000 rounds of bullets, for a total of 20,000 rounds of bullets. Fortunately, this machine gun fires quickly, so it may be finished before the rifle.

The test procedure is to replace the barrel every 1,000 rounds of bullets, without any cleaning or maintenance in between, and only replace the overheated barrel once; then perform a simple maintenance after firing 5,000 rounds of bullets, and the barrel still does not need to be cleaned. Finally, after firing 10,000 rounds of bullets, clean the barrel and main mechanism again.

After testing according to this process, use tracer bullets to retest the accuracy subject to see if there is a significant decrease in the performance of the entire gun.
