And how do breech-loading firearms that use metal cartridge bullets solve the air leakage problem?

Because the propellant burns in the cartridge case and generates high-temperature and high-pressure gas, which then pushes the warhead forward. It does not burn directly in the barrel like caseless ammunition or paper-cased ammunition.

The bottom and periphery of the cartridge case are of a closed structure, so there is no problem of tail air leakage.

At the same time, after the cartridge case expands driven by the propellant gas, the cartridge case will be closer to the gun bore. In this way, when the warhead leaves the cartridge case, even if the high-temperature and high-pressure gas is poured into the gun bore, it will not be able to pass through the gap between the cartridge case and the gun bore.

Passed backward, causing leakage from the locking mechanism at the rear of the gun...

The combination of the two means that breech-loading rifles that use metal shell bullets do not have the problem of air leakage in the tail locking mechanism.

In addition to using metal shell bullets, according to modern industrial standards, no matter what kind of breech-loading rifle you use with a locking structure, you cannot solve the air leakage problem well.

The Dachu Empire’s concept bolt-action breech-loading rifle from the Firearms Research Institute also cannot solve the air leakage problem.

After all, the industrial technology of the Da Chu Empire was still limited. In many aspects, it was actually not comparable to that of later countries in the mid-19th century. Therefore, the air leakage problem of this concept rifle was even more serious, and it was not even reliable for actual use.

Spectrum.

In this regard, Luo Zhixue also continued to remind his group of technical experts not to focus on the firearm itself, but also to pay attention to the ammunition problem, so he asked a group of experts from the Firearms Research Institute: bolt-action breech-loading rifled gun

The prospects are bright, but the process is tortuous. What we have to do is to continue to study unswervingly and strive to solve the problem as soon as possible.

It is not only necessary to conduct more careful research on the firearm itself, but also on the ammunition system. For example, for the paper shell ammunition currently used, can the paper shell be replaced by a copper shell?

Can the air leakage problem be solved by replacing the paper shell with a thin copper shell?"

Luo Zhixue just mentioned it casually. Anyway, he also knew that even if he proposed a solution now, just like the Mini rifle, it would be impossible to mass-produce custom-made metal equipment with the current industrial strength of the Da Chu Empire.

Bullets and supporting breech-loading rifles.

Even if it can be produced, its extremely high production cost will mean that the military cannot afford it... A rifle worth several hundred yuan, if you shoot the generals of the army and navy one by one, they will not be able to spend so much military expenditure to equip them in batches.

Weapon system with breech-loaded metal bullets.

But, let’s give them an idea first, let them study it slowly, and then test a small number of products first.

Luo Zhixue's requirements are not high. He just needs to get some for testing first and build a test unit for breech-loading rifles. As for large-scale batch equipment, it will not be too late to equip them after the production costs come down.

But the research on new weapons...has to be ahead of the progress of industrial technology.

After seeing the concept version of the bolt-action rifle, Luo Zhixue also saw several other breech-loading rifles with locking schemes, some of which can be fired with live ammunition, but air leakage is generally quite serious.

It's okay to get some small-scale test equipment for such a breech-loading rifle, but large-scale equipment is unnecessary. This thing costs nothing to give to the military, and the military doesn't dare to ask for it... If it really needs to be equipped in batches, the soldiers will have to

Rebellious.

The soldier who went blind because of a leak in his breech-loading rifle...

Therefore, it is very difficult to equip a breech-loading rifle. Don’t expect metal bullet rifles in a short time. This thing requires too high industrial technology, even higher than any rifled rifle.

With the industrial base of the Dachu Empire, there is no hope of mass production within ten years. If it is barely produced ten years later, it is probably an extremely expensive weapon.

For paper shell bullets, the problem of air leakage must be solved. It is impossible to completely solve this problem, but through continuous technical improvements, the degree of air leakage can be controlled within an acceptable range.

And this requires the continued efforts of those technical experts.

Luo Zhixue could give them a structural design concept for bolt-action locking, but he couldn't improve the processing accuracy and completely solve the air leakage problem.

I could give them an idea, so Luo Zhixue reminded the Firearms Research Institute that they could try using rubber gaskets to alleviate the air leakage problem.

As for how to do it specifically, technical experts still need to conduct research and testing to find a feasible solution.

After seeing a variety of front-loaded and breech-loaded rifled rifles, Luo Zhixue also looked at the latest model of the Type 21 flash cap percussion gun in service, which is the Type 21 Type A-2.

Some detailed adjustments have been made on the basis of the original model, with little improvement in performance, but more to reduce production costs...

In order to control costs, no other major improvements have been made, such as barrel materials and processing accuracy, which remain at the original level.

Anyway, flintlock guns don’t require high processing accuracy. There’s no need to be too high-tech, just make them as cheap as possible!

Moreover, the military also has to consider the use of the 21-year-old rifles modified from a large number of the original 13-year-old flintlock rifles, which makes it even more difficult to change.

In fact, the so-called 21-year-old rifles currently equipped in large numbers in the Chu Empire's military were actually improved from the 13-year-old series of Suifa rifles.

There are actually only more than 300,000 newly produced Type 21 rifles, and the remaining more than one million Type 21 percussion guns are all modified from Type 13 flintlocks.
p>

After all, the military can't just leave a large number of 13-year-old rifles unused and then turn around and purchase a large number of new guns.

Under such circumstances, in order to avoid a large amount of modification costs and allow soldiers to better adapt. More importantly, in order to reduce production costs, in principle, the Type 21 percussion rifle can be modified as long as it can.

However, if you want to equip rifled rifles in the future, whether it is a front-loading rifled rifle or a breech-loading rifled rifle, I am afraid that these front-loading smoothbore rifles will not be able to be modified, because the barrel level is not high enough, and even if you reluctantly modify it, you will have to be wary of using it.

Worry about exploding!

The military's plan is actually very simple. It is to first use a large number of 21-type A-1 rifles modified from the 13-year-old Suifa rifles, and then continue to produce some new 21-type rifles.

Normal replacement.

When the later rifled rifles are developed and can be used in large-scale service, then we can directly equip a large number of rifled rifles in one step.

As for whether it is a front-loading rifled rifle or a breech-loading rifle, it depends on the subsequent technological research and development progress and the progress of the industrial level. If the situation is good, then directly equip the breech-loading rifle in one step. If the technology is half a bucket of water,

Then equip a batch of front-loading rifled rifles for the main force to use. When the breech-loading rifles come out later, the front-loading rifles can be converted into breech-loading rifles.

Although there is not even a shadow of a rifled rifle, the Army already has relevant modification plans and is conducting preliminary research... This research is how to modify the Type 16 front-loading rifled rifle at the lowest possible cost.

It is a breech-loading rifle.

The Army has made over-preparations for its future rifle equipment plan.

On the other hand, the Navy is much simpler. The Navy's rifles have always followed the Army's lead... They will use whatever the Army uses, but they will just make improvements to meet the Navy's special needs, such as using a shorter barrel.

, pay more attention to corrosion prevention, etc.

After looking at the many messy rifles, Luo Zhixue went to the pistol exhibition area. Compared with the rifles, the pistols had more styles and more complex models... There were all kinds of messy designs.

However, most of them are single-shot pistols, including front-loading rifled pistols and breech-loading rifled pistols... But what caught Luo Zhixue's attention was a repeating pistol. This thing looked like something from his memory.

A revolver.

Seeing Luo Zhixue looking at the revolver ahead, the person in charge of the Hebei Company immediately stepped forward and said: "Your Majesty, this is the Tianqi revolver repeating pistol developed by our company for the cavalry troops."

As soon as you hear the name, you will know that it is the seventh type of pistol developed and produced by the Tianjin Arsenal, a subsidiary of Hebei Arms Company... The factory name plus a numerical number is the naming convention of the defense industry of the Dachu Empire. Except for those large-scale equipment, the year of acquisition

Except for numbered standard weapons, other small-scale weapons and equipment are basically named in this way.

Luo Zhixue took a step forward and picked up the Tianqi revolver. After looking at it carefully, he found that this thing was not the real revolver that he remembered, because the bullet chamber of this thing was fixed on the gun body and could not be compared with future generations.

The revolver can also be flipped out.

In this case, Luo Zhixue feels that loading may be troublesome.

In other aspects, it is very good. The size is suitable and the weight is a little heavy, but it is within the acceptable range.

The grip has obviously been carefully shot and is relatively comfortable to hold, and there is rifling in the barrel. Paper-packed bullets can be used in front of the bullet chamber, and a flash cap is installed in the rear. The firing distance is similar to that of a front-loading rifled rifle.
p>

"This gun looks quite novel, with rifling engraved on it. How about the processing cost?"

The person in charge of Hebei Arms Company immediately said respectfully: "Your Majesty, although the cost of processing rifling for rifles is relatively high now, that is because the barrel of the rifle is too long and the overall processing is difficult. And our cavalry runner

The barrel of the pistol is very short, the processing difficulty is relatively low, and the accuracy is easy to control. Although the overall cost is much higher than that of previous smoothbore pistols, it is not too high!"

"And we also have the advantage of continuous fire. After one-time reloading, the cavalry can fire six times continuously during the battle, which greatly improves the cavalry's close-range firepower."

Luo Zhixue continued to look at the revolver in his hand, then handed it to the person in charge next to him and said: "Arrange for someone to test fire it!"

Again, you’ll know if something works or not by trying it!

At today's weapons exhibition, there were a lot of weapons and equipment that were said to be very flashy, but were actually unreliable... In order to win His Majesty's attention, many people took weapons and equipment that were still under development and could not be put into practical use at all.

When it came out, it was just like the previous breech-loading rifle... It sounds nice, but even the air leakage problem cannot be solved, and the cost problem cannot be solved. It is destined to not be put into actual combat for many years.

As for the revolver in front of us, we have to wait and see. If the performance is reliable and the cost is not too outrageous, Luo Zhixue really hopes that his cavalry can be equipped with this new revolver repeating pistol. This pair of cavalry

The improvement of combat effectiveness is of great benefit.

Maybe the pistol cavalry, which was a short-lived flash in the pan, can reappear in the cavalry troops of the Da Chu Empire... I just don’t know if the cavalry generals are willing.

After all, the current cavalry generals of the Great Chu Empire are very repulsive to pistols. The cavalry pistols issued to them are basically only used as decorations... Even the latest flash cap fired smoothbore pistols equipped in recent years are not

Favored by the cavalry.

At present, the cavalry troops of the Dachu Empire only use cavalry pistols in combat under special circumstances.

In the past twenty years, pistols have always been very embarrassing in the cavalry troops of the Great Chu Empire. The cavalry likes to use sabers on horseback, and they use rifles directly when dismounting. As for pistols, sorry, they are not included in the tactical options.

Stuff.

If there is such a revolving rifled pistol, this situation may be changed.

Soon, the test firing began. To Luo Zhixue's expectation, the test firing of this Tianqi revolver was very successful. The shooter fired six rounds of bullets in a very short time. Just at this rate of fire

, which attracted Luo Zhixue’s great attention.

The live-fire shooting results reported subsequently were also quite good, with a very high target accuracy at a distance of thirty meters, far exceeding the previous single-shot muzzle-loading smoothbore pistol.
