My Daming New Empire

This process is also very simple, you only need to fix the milling cutter, and then when the lathe advances the barrel, it advances in a rotating manner.

But no matter how simple it is, the corresponding equipment needs to be improved so that it can mass-produce accessories.

Zhu Zhanji never thought of being able to manufacture an automatic rifle that can automatically eject the cartridge case at one time. Nowadays, the output of copper is not enough, and the cartridge case needs to be recycled, and the automatic rifle consumes more resources.

When countries in the world did not have muskets, a Mauser 1898 would be invincible.

The linkage mechanism inside the gun is completely unknown to laymen, but to Zhu Zhanji, it is not difficult at all.

In his previous life, he was very familiar with guns from all over the world, and he could assemble a gun with his eyes closed, so he was very familiar with these accessories.

The hammer, trigger, linkage, spring, and the inside of a gun are mainly these components.

What he has to do now is to make a gun by hand, then adjust the size of each accessory, determine the model of the accessory, and then improve the processing mold of the lathe according to these models of accessories.

But now there is a problem, that is, his familiarity with pistols far exceeds that of long guns.

He is very sure now that he can make himself a Boleta 92, which was also his favorite pistol in his previous life.

As for the long gun, the one he plays with the most is the SAR-21 fully automatic rifle produced by Singapore New Century. With the current technology, he doesn't even think about that kind of gun.

In this way, he can't make complicated ones, and he is not familiar with simple ones. It will take a while to study the finalization of various accessories.

He handles official business every morning, and in the afternoon, Zhu Zhanji is definitely at Xiamaqiao Farm, playing with his toys.

During this period of time, Ma Di started to be his good student again. Seeing Zhu Zhanji scribbling and changing the drawings, it became a hundred thousand whys.

If he didn't really like him, Zhu Zhanji would be so annoyed that he would kick him out.

Before the spear was ready, Zhu Zhanji had already completed a Boleta first.

In terms of craftsmanship, this gun is absolutely inferior to the craftsmanship of later generations, and in terms of material, it is impossible to be as wearable as later generations.But with the gun jointly built by the best craftsmen of Ming Dynasty, it definitely has the level of the early [-]th century.

Zhu Zhanji only made two pistols, and then destroyed all the accessories.

This pistol was made by him to satisfy his hobby of playing with guns, so he didn't want to spread it out now.He won't be popularized for at least a few decades.

Because long guns are easy to guard against, this pistol is not easy to guard against. If someone uses this pistol to assassinate him, he will overplay it.

It is easy to make samples of other accessories of the spear, but the linkage mechanism has been changed and changed. It took Zhu Zhanji nearly a month, but the problem still has not been completely solved.

Moreover, the primer mercury fulminate promised by Blue Smoke has still not been produced.

Mercury fulminate is the earliest primary explosive, which has high sensitivity to flame, needle stick and impact.For more than 100 years since its invention, it has always been an important component of detonator charges and flash cap firing charges.

However, mercury fulminate has relatively poor stability and is highly toxic. The percussion agent containing mercury fulminate is easy to corrode the barrel and cartridge, and has been replaced by another safer lead azide in later generations.

Although Lan Yan knew the craft of mercury fulminate, Zhu Zhanji was determined not to let her try it out by herself.

This kind of gunpowder is highly poisonous and has poor stability. If something happens to her, Zhu Zhanji will suffer a great loss.

And let those gunpowder experts experiment, two people have died, but they still haven't been able to stabilize the gunpowder.

In addition to the lack of research and development of mercury fulminate, the other is the production of the copper skin of the primer. Today's processing technology is difficult to mass-produce the paper-thin copper skin.

On the contrary, no matter whether it is round pistol bullets or pointed long gun bullets, a batch has already been produced by hand.

These bullets are all copper-skinned lead-core bullets, and the processing size is strictly in accordance with Zhu Zhanji's requirements. Although they cannot be mass-produced for the time being, the craftsmanship is absolutely not picky.

As for the cylindrical shell, the wire drawing process is used to directly produce the copper tube, and then cut into pieces.

Propellant powder is not difficult for Blue Smoke, nitrocellulose smokeless powder can be divided into single base, double base and triple base, these three types of gunpowder are not difficult.

Lan Yan only gave the processing technology, and the gunpowder master used a mixed solution of purified ethanol and ether to dissolve and gel the nitrocellulose to produce colloidal gunpowder.

Subsequently, the light agent graphite and the passivating agent camphor were added to the gunpowder composition to form a safe granular propellant gunpowder.

Zhu Zhanji's "not doing business properly" made many ministers a little dissatisfied, but now is the hottest time of the year, and many ministers have unconsciously reduced their workload.

Although Zhu Zhanji "doesn't do his job properly", he didn't do anything wrong, and he handled his official duties on time every morning, and there were no ministers who disagreed with him.

Until the beginning of July, the linkage mechanism of the long gun was finally finalized, and a long gun imitating Mauser was produced.

Zhu Zhanji tried his hand, and it was pretty good.

Those gunpowder masters finally produced less than a catty of mercury fulminate, which was packed into a glass bottle and sent to Zhu Zhanji's private workshop in fear.

There was a big accident on the first day of assembly, because there is no processing equipment for the production of the primer, and it is completely manual.

Although Zhu Zhanji gave thousands of instructions, a craftsman still detonated the bullet when he assembled the primer and the shell case.

Fortunately, the bullet directly penetrated his calf, and the casing collapsed, blinding him in one eye, but his life was saved.

What Zhu Zhanji didn't expect was that not only did the accident not scare them, but everyone was very excited.

The bullet has such great power just by hitting it with your hand, which shows that the power of this bullet far exceeds the existing muskets.

Because the previous gunpowder gun, even if it was shot at a person, the bullet could not penetrate the body, it would only leave the bullet in the person's body, making people feel overwhelmed with pain.

After a distance of 100 meters, basically no one can be killed.

But now, it's completely different.

Immediately, researchers asked Zhu Zhanji how far this new gun could shoot.Zhu Zhanji gave them a data of 800 meters, which made everyone dumbfounded and couldn't believe it.

In the original history, Mauser 1898 had a range of 800 meters. Today's gunpowder is purer than before. Zhu Zhanji is still confident in the range of 800 meters.

Of course, if the effective range can reach 400 meters, he is already very satisfied.

When the two hundred rounds of handmade bullets were all manufactured, Zhu Zhanji couldn't wait to take two guns and went to the shooting range of Habayashi Eysaku for a test.

The test firing of the pistol went very well, because it only has a range of 50 meters, and no deficiencies were found.

The bullet was ejected stably, although it seemed a bit astringent because there was no butter, only vegetable oil for lubrication, but Zhu Zhanji was already very satisfied.

But the test firing of the long gun made Zhu Zhanji frown at the first shot.

He test-fired the first bullet at a distance of 200 meters. He could obviously feel the vibration of the gun muzzle was too large and the trajectory was unstable.

Although the bullet finally hit the target, it deviated from the target and almost missed the target.

Li Liang's flattery followed, and he also comforted Zhu Zhanji, saying that being able to hit the target at a distance of 200 meters is already great.

Tried another shot, and this time it's still the same problem.

Zhu Zhanji immediately knew that this was a problem with the rifling.

He has long forgotten the rifling of the Mauser gun, but because he often plays Boleta, he remembers that the Boleta has six riflings, and then right-handed, with a twist of 250mm.
