Chapter 921： Steel core single head bullet (2 in 1)

Marin has been hesitating whether to take out the Minnie rifle, because this gun is too powerful. With this gun, you can hurt people, but if you leak a leak, you can hurt yourself. In the case that he has not yet won the religious war and obtained enough territory, the leak of the Minnie rifle's secret is a disaster. Therefore, Marin refused to "invent" the Minnie rifle and Minnie bullet.

Marin's original plan was to suddenly launch the Minnie rifle and the Minnie bullet before the religious war, and then use the powerful firepower to quickly destroy the enemy and grab enough territory. As for whether the technology will be leaked later, it does not matter.

He was pretty sure that as long as he launched the Minnie rifle and the miniature ammunition, the French would definitely get the secret of the Minnie rifle and miniature ambiguously like the secret recipe of the Venice mirror. Not only France, other countries want military strength, they will do the same.

Before there is not enough strength to resist the covetment from all sides, Marin does not want to come up with a simple and easily plagiarized Mini rifle and Mini bullet. In other words, Marin does not want to mount a rifle gun at the moment, but has to wait and talk.

However, if you do n’t use the Minnie rifle and Minnie bullet, Marin ’s musketeers have no advantage. Shooting with people basically depends on Mongolia. Spherical lead bullets are too easy to roll around, it is really difficult to catch the enemy. Historically, Europeans have shot each other for three or four hundred years by relying on each other. Later, the British realized the truth-standing there to cover each other, it is better to set the fire once in 30 steps with the opponent's firepower, and then rush to fight for the bayonet ...

In other words, the only advantage of Marin's musketeers is that they don't use flaming ropes and are not affected by the weather. The musketeers are not denser than 1 meter apart. However, no matter how densely arranged, it is still blinding to shoot people ...

...

So, when Marin refuses to launch a rifle gun, the best killer is to use the peak killer of the rifle gun, the one-shot.

Although the power of the one-headed bullet can't keep up with the Minnie's bullet, but within a hundred meters, you don't need to be blinded. Within 150 meters, most one-shots are also very accurate. And some well-crafted single-headed bullets can even hit accurately at a distance of 200 meters (of course, it takes some luck).

If a single-headed ammunition is used, then Marin ’s musketeers can hit each other, no longer blindly, but aim at the opponent to harvest the head ...

Especially, if you are aiming at the opposing commander, it would be even better ...

Before the emergence of the modern army, the European army, like the Asian army, was very dependent on the commander. If the commander dies, the army will most likely collapse. Therefore, the commander's command will benefit greatly.

In this era, in order to show courage, commanders often lead their troops in a more advanced position, encouraging soldiers to command on the spot. Generally speaking, even if the commander is not at the forefront, it must be nearby. At least, within 200 meters.

In addition, the commander usually rides a horse, and the upper half of the body will definitely be exposed to let you aim ...

Therefore, with a single bullet that can accurately kill an officer within 200 meters, the impact on the battle situation will be greater.

...

In addition, the reason why Marin favors single-headed ammunition is because the technical requirements of single-headed ammunition are very high!

Yes, don't look at the single-headed bullet as a smooth-bore bullet, but its process requirements are very high. It engraved the rifle in the bullet's head, so that the wind can be used to rotate the bullet ...

The problem lies here ...

In general, when using a rifled gun, a barrel can be used repeatedly. Therefore, even if a barrel is scrapped, it is a big deal to replace it. I had no choice but to pass the inspection of the barrel and go to the battlefield.

But the one-headed bullet is different ...

The single-headed bullet engraved the rifle on the bullet. If the rift was skewed, it would be miserable, and it would also be skewed directly, causing a miss.

Therefore, the rifle of the head of the single-headed warhead must be carved accurately and symmetrically, and there must be no mistake. Otherwise, the purpose of using wind power will not be achieved. Moreover, it must be the same for every single bullet.

This is difficult, not to mention the manufacturing level of the early 16th century, even in the arsenal of Tubalu during the Anti-Japanese War of the 20th century, which absolutely could not meet this requirement. And the consequence of failing to meet the requirements is that the bullet cannot hit precisely ...

What's more terrible is that the bullets in this era were made of lead. What is lead? Soft! If it bumps during transportation and the sun rift is damaged, the bullet will be useless.

Therefore, the shotgun shells of later generations are all sealed and packed in the hard plastic shell of the shotgun shells, so as not to bump. But what is the musketeer's habit now? They all took out lead bullets from their bags and let them pierce the barrels with iron rods. Treating it like this will definitely make the lead-only bullets useless.

In addition, in this era, European artisans manufactured items, and the quality control was also very loose. It was difficult to accurately produce single-headed bullets that met aerodynamic requirements. Unlike later generations who used automatic machine tools directly, the accuracy was very high.

...

However, Marin is not afraid of accuracy. Big deal, take the high-end route. Moreover, since the strict quality control of vernier calipers has been promoted, the precision of Beihai Machinery Manufacturing has been greatly improved, and it is definitely far more than other European countries in the same era. At present, the accuracy of other European countries is still in the millimeter level, while the manufacturing accuracy of the Beihai country has reached the 0.1 millimeter level. Of course, this is a requirement when manufacturing fine products, and the scrap rate is also very high. However, this is very suitable for the production of high-demand items such as single-headed bullets. Moreover, high-precision gadgets can also form technical barriers to other European countries.

However, it seems that there is not such a high requirement for the production of single-headed bullets ... Although mass production is more troublesome, it can be manufactured on a small scale, but the difficulty is not great ...

...

Just do it, Marin found Da Vinci, and helped himself to spend a precise drawing, that is, the drawing of the single-headed bullet.

In order to achieve an effective range as far as possible, Marin designed the single-headed ammunition to have a "male rifle on the head and a tail on the tail"

The two-in-one form factor of the two technologies. There are two kinds of stable flight design of male rifle and tail wing, the bullets fly more stable, and the effective range is naturally higher.

The drawings are very good, after all, Marin is a master of drawing, and Da Vinci is a holy hand of drawing. As long as you pay attention to the symmetry of the sun rifling, there will be nothing.

However, it is not too difficult to transform it into a physical object. In modern times, as long as the drawing data is input into the computer, then the CNC machine tool can easily cut it out for you. But this handicraft age ...

Marin found several carpenters who were good at carving, and carved prototypes of single-headed bullets in wood according to the drawings day and night. After carving, he personally used vernier calipers to measure one by one ...

In this way, after thousands of failed products were discarded in carving, Marin finally got 5 qualified finished products.

Then, Marin found pottery craftsmen and asked them to make pottery clay. After preparing the clay, Marin inserted 5 qualified single-headed wood models into the clay to obtain the model space. Then, he let people use a thin blade to dry the clay model for a while, from the middle to the second. Then, the pottery clay model that was divided into two halves was sent to the furnace and fired ...

In the same way, Marin made a hundred Tao Fan. But after the final acceptance, only 7 qualified products remained. However, this is enough.

With Tao Fan, it's easy to make a one-shot bullet-Marin combines the two halves of Tao Fan into one and then pours molten lead. After cooling down, breaking apart the two halves of Tao Fan, you got a single head bullet.

...

However, when trying to fill and test the effect, Marin encountered a big problem. This is the same as he thought before-the filling is easy to deform the single head ...

Because it is used by the front-loading smoothbore gun, the single-headed bullet also needs to be stabbed into the barrel with a steel rod. However, the lead-only one-shot is so soft, how can it be stabbed hard with an iron rod? Definitely will stab it ... and once it stabs, it won't be far ...

How to poke the single-headed bullet safely to the bottom of the barrel? This problem has troubled Marin for a long time ...

At the same time, another problem is also great-since the tail is changed to a mortar-like tail, the tail may not be able to close the bullet. Moreover, paper jams or leather pads are not good. Because after the gunpowder breaks through the protection of paper **** or leather, there will still be problems with the force acting on the bullet. The small tail can't bear the thrust of enough gunpowder gas. In other words, the thrust of gunpowder gas does not work well on the one-shot ...

...

"How will future generations solve this problem? Add a wooden ammo?" Marin began to recall ...

Indeed, adding a cylindrical cork cartridge behind the tail of the single-headed bullet can solve the problem of air confinement, and the cork cartridge can completely absorb the thrust of the gunpowder gas and transmit the thrust to the tail of the single-headed bullet.

...

So, the last question remains-how to prevent the male rifling of the head of the single-headed bullet from being stabbed by the iron rod when loading the bomb?

Cancel the male rifling on the head and only keep the wing? This is a solution. However, it will reduce performance. Without the male rifling that caused the rotation, the effective range of the one-shot would definitely be reduced a lot.

However, without canceling the male rifling on the head, the lead bullets can't help the brutal chaos of the iron rod ...

...

For several days in a row, Marin had some trouble solutions. Just when he was planning to compromise and was about to cancel the male rifle of the single-headed head, he suddenly found inspiration on the dinner table ...

Robert the bear boy, the future pope in Marin's heart, plucked an egg naughtily with a chopstick during a meal, and then waved chopsticks with eggs and laughed. Then, another bear child, Caesar, also learned something, poke an egg with chopsticks, and waved ...

Marin suddenly came to inspiration——

"Soft lead ... pierce through ... or let the iron rod pierce the lead bullet directly?" Marin thought about it, or shook his head.

There are indeed empty pointed bullets in later generations, and the hollow center shaft can also be used. But the problem is that if the TieTong sticks down, it may not be so accurate. Once the lead bullet is skewered and the center of gravity changes, the bullet is useless ...

"Or, just make a central axis for the lead shot?" Marin was inspired by the chopsticks waving by two bear children ...

...

Then, he modified the model and punched it into a mold so that a thin iron bar was inserted on the central axis between the head of the single-headed warhead and the tail.

The thin iron bar extends a part after penetrating the rear wing, and is inserted into the cylindrical cork cartridge, perfectly combining the one-shot and the cartridge.

On the head of the single-headed warhead, a thin iron bar also stretched out a part. The role of this part is to make the iron stick ...

After all, the bullet needs to be forced into the bottom of the barrel. The one-headed bullet made of lead itself cannot be brutally forced. However, this thin iron rod that serves as the central axis can be poked. Because, it is fixed on the cork cartridge, stab it will not hurt the single-headed bullet itself.

After testing, this single-headed ammunition with a thin iron bar was stabbed safely into the bottom of the barrel. During the test firing, the effective range actually reached an astonishing 170 meters.

On the edge, the onlooker Da Vinci suddenly said:

"According to the principle of aerodynamics, after the bullet is discharged, the wooden hanger hanging behind it seems that the air resistance is large, which affects the range ..."

Marin nodded and admitted the situation. In fact, the main function of the wooden ammunition is actually to transfer the thrust of gunpowder gas. After the sprung popped out of the barrel, because of its own tail, the role of the wooden ammunition is actually dispensable. Even attached to the cartridge holder actually hindered the bullet flight.

"Otherwise, did we make the connection between the iron bar and the susceptor movable?" Leonardo suddenly suggested.

"Why?" Marin didn't respond.

"I think that if the connection between the iron bar and the wooden cartridge is active, after the bullets fly out, the wooden cartridge may fall off automatically due to air resistance. Anyway, you said that with the tail, the wooden cartridge It ’s useless to hold out the barrel. ”Da Vinci explained. During this period of physics study, the scientific theory level has been greatly improved. Even, in many ways, it surpassed Marin as a teacher.

Marin was dumbfounded:

"Isn't this a stable tail-shell armor-piercing projectile?"

But he quickly shook his head and said:

"No, it's not shelling, it's removing the burden of shelling, but the meaning is similar!"

Marin was excited to get the barb between the iron bar and the cork base removed, so that the iron bar's center axis could be easily separated from the cork cartridge.

In the second test, shortly after the son was ejected, the cork cartridge was separated from the one-shot due to air resistance. Without the drag of the air resistance of the cork cartridge, the two-headed single-headed projectile (windward sun rifling and tail stabilization technology) united with an effective range of 200 meters ...

"So dang ..." Marin was dumbfounded. 200 meters, which is basically the limit of a single shot ...

Then, Marin looked at Da Vinci with admiring eyes-it was a man who could imagine a helicopter and made a mechanical lion. Just give a suggestion and it had such a good effect ...

But before he was pleasantly surprised, Da Vinci made another good suggestion:

"Or, replace that iron bar with steel nails? The kind made of high carbon steel ..."

"why?"

"Break the plate armor protection!"

"Oh ... yeah, isn't this a later carbide-pointed armor-piercing projectile?" Marin suddenly realized when he saw the new one-shot projectile with the nail head exposed in front of it.

Of course, it can also be regarded as a steel-core bomb that will deal with body armor. With the pointed impact of high carbon steel nails, the ability of bullets to break the plate armor defense has been greatly improved.

If it is a pure lead single-headed bullet, it hits the plate armor, although it can hurt the person wearing the plate armor with impact force, and can even form a pit on the plate armor. However, lead is too soft after all, making it difficult for lead bullets to penetrate the plate armor. It can only hurt the person wearing the plate armor through the plate armor and cannot be fatal.

After testing, this is indeed the case-a single-headed bullet with a steel nail as the core, although it penetrated some plate armor, but only the steel nail pierced the plate armor, leaving small eyes, while the lead bullet part cannot penetrate.

However, the huge kinetic energy brought by the lead projectile itself can injure people wearing plate armor. Coupled with the puncture damage of nails, the power is much greater than that of a simple lead projectile.

Moreover, Marin also improved the steel nail as a steel core-for example, grinding the bleeding groove on the head of the steel nail to bleed the shot. Even, poison can be wiped in the blood tank, causing more serious damage to the enemy. If there is a bit of Hua Xia's "see blood to seal the throat" in the blood trough, then it is a killing skill.

In order to improve the strength of steel nails as steel cores, Marin also allowed craftsmen to further grind the nails of high carbon steel with bleeding grooves, and then further carburize and quench the steel nails to further strengthen the nail tips. Hardness, strengthen the ability to break armor.

After seeing several instances of steel core single-headed bombardment of the plate armor, Marin was shocked:

"Obe, this is a big match. In 1508, Lao Tzu made out the armor-piercing shells that could only penetrate the humanoid armor (plate armor) only in the 20th century? In the future, it is not safe for Lao Tzu to wear plate armor?"

Thinking of this, Marin's face changed greatly. Then he gritted his teeth and called Kohler:

"Relocate all the craftsmen who participated in the development of the steel core single-headed bullets to a hidden place. They must never be allowed to come in contact with outsiders. If there are outsiders who dare to get close to it, don't kill them!"

Kohler quickly led away, and Da Vinci looked at Malin contemptuously:

"Is it necessary? If you use bullets on the enemy, the enemy will not be able to see what the bullet is like?"

Marin chuckled, and got the bullets after the test. He told Da Vinci:

"Look for yourself!"

Then, Leonardo saw an iron nail, and a pile of lead ... Obviously, under a huge impact, the soft lead bullet was squeezed and deformed. Where can I see the original look?

It can be said that unless it hits the water and the sludge, the softness of lead will squeeze into a pile of lead as long as it is impacted, and it is difficult to recognize the original appearance. In particular, the male rifling on the head first contacted the target, the first one was squeezed out of shape, and the original look was completely unseen.

As for the tail, Marin is not worried. Because, the wooden ammunition has fallen off long ago. The enemy gets only small tails and bullets, but they are also transformed. But if you do n’t know the technology of the wooden ampoule, the thin tail ca n’t bear the responsibility of being propelled by the gunpowder gas ... and obviously, people in this era do n’t know the technique of the ammo pad. Only appeared in the century ...

Anyway ~ www.novelhall.com ~ As long as the user does not hit the bullet in the water or the quagmire, it is difficult for the enemy to get a good steel core single headed bullet.

Of course, the use and preservation of steel-core single-headed bullets are even more important. Marin decided to pick a team of musketeers who were the most successful and most loyal to brainwashing and use this advanced ammunition. In addition, during peacetime, bullets are not fired and stored in a warehouse with a very high level of defense. Outsiders are strictly prohibited from contact. Only before the war, this powerful bullet will be issued, which is specifically used to shoot the enemy's senior generals and plate armor knight ...

In this way, it is possible to fully avoid confidential disclosure. As long as the enemy cannot steal the bullet sample, they cannot copy it. The musket that fired this bullet was no different from that used by other musketeers. Even if the firearm is stolen, there will be no impact ...

...

"Charge ... Insert the tail of the high-carbon steel nail on the central axis of the one-headed bullet into the cylindrical cork cartridge ..."

"Apply whale oil to the cork cartridge (to reduce friction) and tuck into the barrel ..."

"Then, use a thick iron rod to press the steel nail tip and push the bullet into the bottom of the barrel ..."

"Um ... the next step is to aim and shoot ..."

"boom--"

After the gunshot, Marin went to see the target himself-a thick iron plate about 180 meters away, stuck in a steel nail. And at the tail of the steel nail, there is still a piece of lead ... the iron plate is pierced by the steel nail, and that piece of lead has also smashed a big pit in the iron plate ...

If there is a person behind this iron plate, this person must have a blood hole pierced by steel nails. In addition, Na Tuo lead him to break several rib-level internal injuries ... If the steel nails were poisoned, then it was dead ...

This is a thick iron plate, the highest level of plate armor. If it is replaced with inferior plate armor, the bullet will break through the whole body, break into the human body, and stir the internal organs-KO ...
