The Rise of the European Emperor

Marin has been hesitant to take out the Mini rifle, because this kind of gun is too powerful. With this gun, it can not only hurt people, but if the secret is leaked, it can also hurt itself. In the case that he has not won the religious war and obtained enough territory, the secret of the Mini Rifle is leaked, which is simply a disaster. Therefore, Marin was reluctant to "invent" the Mini rifle and the Mini bullet.

Marin's original plan was to suddenly launch the Mini rifle and Mini bullet before the religious war, and then use the powerful firepower advantage to quickly destroy the enemy and grab enough territory. As for whether the technology is leaked later, it doesn't matter.

He was sure that as long as he introduced the Mini rifle and the Mini bullet, the French would definitely get the secrets of the Mini rifle and the Mini bullet by any means, just like the secret recipe of the mirror of Venice. Not only France, but other countries wanting to be strong militarily will do the same.

Before not having enough strength to resist the coveted by all parties, Marin did not want to come up with the Mini rifle and Mini bullet with simple technology and easy to be stolen. That is to say, Marin doesn't want to mount rifled guns at the moment, but will wait and see.

However, Marlin's musketeers have little advantage without the use of Mini rifles and mini bullets. Shooting against people is basically relying on Mongolia. The spherical lead balls are too easy to roll and fly around, and it is really difficult to hit the enemy. In history, Europeans used muskets to shoot at each other for three or four hundred years. Later, the British realized a truth - standing there blinded by each other, it is better to focus fire once within 30 steps against each other's firepower, and then rush up to fight the bayonet...

In other words, the only advantage of Marlin's musketeers now is that they don't need matches and are not affected by the weather. The musketeers are no more than 1 meter apart and can be arranged more densely. However, no matter how densely they are lined up, shooting at people is still confusing...

...

Then, in the case that Marin refused to launch the rifled gun, using the pinnacle of the musket, the single-headed bullet, was the best choice.

Although the power of the single-headed bullet can't catch up with the mini bullet, but within 100 meters, you don't need to be blinded. Within 150 meters, most single-headed bullets 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 bullet is used, then Marin's musketeers can shoot each other without being blind, but aiming at the opponent and harvesting the head hard...

In particular, it would be even better if the target was all the opposing commanders...

Before the advent of modern armies, European armies, like Asian armies, were heavily dependent on commanders. If the commander dies, the army will most likely collapse. Therefore, the benefits of killing the commander are huge.

In this era, in order to show courage, commanders often lead their troops to walk in a relatively advanced position, encourage soldiers and commanders on the spot. Generally speaking, if the commander is not at the front, he must be nearby. At least, within 200 meters.

In addition, the commander is usually on horseback, and his upper body will definitely be exposed for you to take a look...

Therefore, with a single-headed bullet that can accurately kill officers within 200 meters, it will have a great impact on the war situation.

...

In addition, the reason why Marin favors the single-headed bullet is because the craftsmanship of the single-headed bullet is very demanding!

Yes, don't look at the single-headed bullet as a musket bullet, but its technological requirements are very high. It engraves the rifling on the bullet's head to use the wind to spin the bullet...

The problem is here...

In general, with rifled guns, one barrel can be used repeatedly. Therefore, even if one barrel is scrapped, it's a big deal to replace it. Had no choice but to pass the barrel inspection and go to the battlefield, generally there would be no major problems.

But the single-headed bomb is different...

The single-headed bullet has the rifling engraved on the bullet. If the rifling is crooked, it will be miserable, and it will fly crooked directly, causing it to miss the target.

Therefore, the rifling of the head of the single-headed bullet must be precisely and symmetrically engraved, and there must be no mistakes. Otherwise, the purpose of using wind power will not be achieved.

Moreover, every single-headed bomb must be like this.

In this way, it is difficult, not to mention the manufacturing level in the early 16th century, even in the arsenal of Tuba Road during the Anti-Japanese War in the 20th century, it can never meet this requirement. And the consequence of not meeting the requirements is that the bullet cannot hit accurately...

Worse still, the bullets of this era were made of lead. What is lead? Soft! If it is bumped in transit and the rifling is damaged, the bullet will be useless.

Therefore, the single-headed shotgun bullets of later generations are sealed and packaged in the hard plastic shell of the shotgun bullet, so as not to be bumped. But what's the habit of Musketeers now? They all took out lead bullets from their bags, and let them stab them roughly into the barrels with iron rods. Treating it like this will definitely ruin the lead bullet.

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

...

Marin isn't afraid of accuracy issues, though. The big deal, take the high-end route. Moreover, since the promotion of vernier calipers to strictly control the quality, the precision of Beihaiguo machinery manufacturing has been greatly improved, which is definitely far superior to other European countries of the same time. Now, the accuracy of other European countries is still millimeter level, while the manufacturing accuracy of Beihai country has reached 0.1 millimeter level. Of course, this is a requirement when manufacturing high-quality products, and the rejection rate is also very high. However, this is very suitable for the production of high-demand things such as single-headed bullets. Moreover, high-precision gadgets can also form technical barriers to other European countries.

However, it seems that manufacturing a single-headed bomb does not have such high requirements... Although mass production is more troublesome, it is not difficult to manufacture on a small scale...

...

As he said, he did, and Marin asked Da Vinci to help him spend a precise drawing, which is the drawing of a one-headed bullet.

In order to achieve the longest possible effective range, Marin designed the single-headed bullet with a "male rifling on the head and a tail on the tail".

Two technologies in a two-in-one form factor. There are two stable flight designs of positive rifling and tail working together, the bullet flies more stably, and the effective range is naturally higher.

The drawings are very easy to draw, after all, Marin is a master of drawing, and Da Vinci is a master of drawing. As long as you pay attention to the symmetry of the male rifling, it will be fine.

However, it's not too difficult to turn it into a real thing. In modern times, as long as the drawing data is entered into the computer, the CNC machine tool can easily cut it out for you. But in this age of craftsmanship...

Marin recruited several carpenters who were good at carving, and worked day and night to carve the prototype of the one-headed bullet out of wood according to the drawings. After engraving, he personally measured one by one with a vernier caliper...

In this way, after the engraving scrapped thousands of failed products, Marin finally got 5 qualified finished products.

Then, Marin recruited pottery artisans and asked them to prepare clay. After preparing the clay, Marin inserted 5 qualified single-headed bullet wood models into the clay to obtain the model space. Then, he used a thin blade to cut the clay model that had been air-dried for a while, and cut it into two pieces from the middle. Then, the clay model, which was divided into two halves, was sent to the furnace to be fired...

Using the same method, Marin made a hundred pottery vans. But after the final acceptance, only 7 qualified products remained. However, this is enough.

With Tao Fan, making a single-headed bullet is simple - Marin combines the two halves of the Tao Fan into one and pours molten lead. After cooling down, split the two halves of the Tao Fan to get a single-headed bullet.

...

However, when trying to load and test the effect, Marin encountered a big problem. It's the same as what he thought before - reloading can easily deform the single-headed bullet...

Because it is used in a front-loading musket, the single-headed bullet also needs to be stabbed into the barrel with an iron rod. However, the lead bullet is so soft, how can it be stabbed with iron rods? It will definitely be stabbed... and once it is stabbed, it will not be far away...

How to safely stab a single-headed bullet to the bottom of the barrel? This question has plagued Marin for a long time...

At the same time, another problem is also very big - since the tail has been changed to a fin similar to a mortar shell, then the tail may not be able to hold the bullet's air. Also, stuffed paper balls or leather backing will not work. Because, after the gunpowder breaks through the protection of the paper ball or leather, there is still a problem with the force acting on the bullet. The small tail can't withstand enough thrust of gunpowder gas. In other words, the thrust of the gunpowder gas cannot act on the single-headed bullet well...

...

"How did the future generations solve this problem? Add a wooden receptacle?" Marin began to recall...

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

...

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

Cancel the rifling of the head and keep only the tail? This is a way. However, performance will be reduced. Without the positive rifling that causes the rotation, the effective range of the single-headed round would definitely be much lower.

However, unless the positive rifling on the head is removed, the lead bullet can't resist the savage stab of the iron rod...

...

For several days, Marin had some troublesome solutions. Just when he was about to compromise and was about to remove the rifling on the head of the single-headed bullet, he suddenly found inspiration at the dinner table...

Robert, the arrogant boy, the future Pope in Marin's heart, mischievously pierced an egg with a chopstick during a meal, and then he waved the chopstick with the egg on it and laughed. Then, another bear kid, Caesar, followed suit, poking an egg with chopsticks and waving it...

Marin suddenly got an inspiration——

"Soft lead... pierce through... Or, let the iron rod pierce the lead bullet directly?" Marin thought for a while, then shook his head.

There are indeed hollow-pointed bullets in later generations, and the central axis can also be hollow. But the problem is that it may not be so accurate if the iron pass is stabbed. Once the lead bullet is stabbed and the center of gravity changes, the bullet will be useless...

"How about making a central axis for the lead bullet?" Looking at the chopsticks waving by the two bear children, Marin was inspired...

...

Then, he modified the model and made 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.

After penetrating the tail fin, the thin iron bar sticks out a part and is inserted into the cylindrical cork receptacle, perfectly combining the single-headed bomb and the receptacle.

And at the head of the single-headed bullet, a thin iron bar also sticks out part of it. The function of this part is to let the iron bars stab...

After all, the bullet needs to be pushed hard into the bottom of the barrel. The lead bullet itself cannot be stabbed with savage force. However, this thin iron bar as the central axis can be poked. Because it is fixed on the cork stock, stabbing it will not hurt the single-headed bullet itself.

After testing, this single-headed bullet with a thin iron rod central axis was safely stabbed into the bottom of the barrel. During the test, the effective range reached an astonishing 170 meters.

On the side, Da Vinci, who was watching, suddenly said:

"According to the principle of aerodynamics, after the bullet comes out of the chamber, the wooden receptacle hanging behind it seems to have a large air resistance, which affects the range..."

Marlin nodded, acknowledging the situation. In fact, the main function of the wooden bomb holder is to transmit the thrust of the gunpowder gas. And after the bullet pops out of the chamber, because it has a tail itself, the role of the wooden bullet holder is actually dispensable. Attached to the stock, it really hinders the flight of the bullet.

"Why don't we make the connection between the iron bar and the bullet rest movable?" Da Vinci suddenly suggested.

"Why?" Marin didn't respond.

"I think if the connection between the iron bar and the wooden stock is movable, after the bullet flies out, the wooden stock may fall off automatically due to air resistance. Anyway, you said that with the tail, the wooden bullet will fall off automatically. It's no use holding out the barrel," Da Vinci explained. During this period of physical study, the level of scientific theory has been greatly improved. Even, in many ways, surpassed Marin as a teacher.

Marin was stunned:

"Isn't this a 'tail stabilized shelling armor-piercing projectile'?"

But he quickly shook his head and said:

"No, it's not to take off the shell, but to take off the burden of the ammo, but the meaning is similar!"

Marin excitedly had the barbs removed between the iron bars and the cork base, so that the iron bars could easily be separated from the cork stock.

When the test was performed again, shortly after the bullet was ejected from the chamber, the cork holder was indeed separated from the single-headed bullet due to air resistance. Without the drag of the air resistance of the cork carrier, a single-headed bullet with two technologies (windward rifling and tail stabilization technology) combined to achieve an effective range of 200 meters...

"So..." Marin was a little stunned. 200 meters is basically the limit of a single-headed bomb...

Then, Marin looked at Da Vinci with admiration - as expected, he was a man who could imagine a helicopter and make a mechanical lion. Just any suggestion he made had such a good effect...

But before he was finished, 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!"

"Oh... that's right, isn't this a later carbide pointed armor-piercing bullet?" Seeing the new single-headed bullet with a nail head exposed on the front after the modification, Marin suddenly realized.

Of course, it can also be regarded as the kind of steel core bullet specially used for body armor in later generations. With the pointed impact of high carbon steel nails, the ability of bullets to break through plate armor is greatly improved.

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

After testing, it turned out to be the case—a single-headed bullet with a steel nail as the core penetrated some plate armor, but only the steel nail pierced the plate armor, leaving small eyes, while the lead bullet could not penetrate.

However, the huge kinetic energy brought by the buckshot itself can injure people who wear plate armor. Coupled with the piercing damage of the nails, the power is much greater than that of a simple lead bullet.

Moreover, Marin also made improvements to the steel nails that act as steel cores—for example, grinding blood grooves in the heads of the steel nails, so that the victims can be bled. Even, you can smear poison in the blood tank to cause more serious damage to the enemy. If the blood tank is smeared with Huaxia's "see blood and seal the throat", then it is simply a nirvana.

In order to improve the strength of the steel nail as the steel core, Marin also asked the craftsmen to further surface carburizing and quenching the steel nail after grinding the blood groove on the head of the high carbon steel nail to further strengthen the nail tip The hardness, strengthen the armor-piercing ability.

After seeing several instances of steel-cored single-headed bullets smashing plate armor, Marin was stunned:

"My dear, this is a big deal. In 1508, Lao Tzu produced an armor-piercing bullet that could penetrate 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:

"Move all the craftsmen involved in the development of the steel-core single-headed bomb to a hidden place, and never let them come into contact with outsiders. If outsiders dare to approach there, shoot them!"

Kohler quickly led the way, and Da Vinci gave Marin a contemptuous look:

"Is it necessary? If you use bullets on the enemy, can't the enemy see what the bullet looks like?"

Marin laughed, and let someone get the bullet after the test, and said to Da Vinci:

"See for yourself!"

Then, Da Vinci saw an iron nail and a lump of lead... Obviously, under the huge impact, the soft lead bullet was squeezed out of shape, where can you still see the original appearance?

It can be said that unless it is hit in water or mud, the softness of lead will squeeze it into a lump of lead as long as it is impacted, and it is difficult to recognize its original appearance. Especially the male rifling of the head, the first to contact the target, the first to be squeezed out of shape, completely unable to see the original appearance.

As for the rear wing, Marin isn't worried either. Because, the wooden ammo has long since fallen off. What the enemy gets is only a small tail and a bullet body, but it is also deformed. But if you don't know the technology of the wooden magazine, the thin tail can't bear the responsibility of being propelled by gunpowder gas... And obviously, people in this era don't know the technology of the magazine. This technology seems to be 19 The century just appeared...

Anyway, as long as the user doesn't hit the bullet into the water or the quagmire, it is very difficult for the enemy to get a good steel core single-headed bullet.

Of course, the use and preservation of the steel core single-headed bullet is even more important. Marin decided to pick out a team of musketeers who were the most brainwashed and most loyal to themselves and used this advanced ammunition. In addition, in peacetime, bullets are not released and are kept in a warehouse with a very high level of defense, and contact with outsiders is strictly prohibited. Only before the war will such powerful bullets be issued, which are specially used to kill the enemy's senior generals and plate knights...

In this way, the leakage of secrets can also be fully avoided. As long as the enemy can't steal the bullet samples, they can't copy it. And the musket that fires this kind of bullet is no different from those used by other musketeers. Even if the firearm is stolen, it will not have any effect...

...

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

"Smear the cork stock with whale oil (to reduce friction) and stuff it into the barrel..."

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

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

"boom--"

After the gunshots went off, Marin went to check the target himself—a steel nail was inserted into a thick iron plate about 180 meters away. And at the tail of the steel nail, there is still a lump of lead... The iron plate was pierced by the steel nail, and the lump of lead also smashed a large pit on the iron plate...

If there is a person behind this iron plate, this person must have a blood hole pierced by a steel nail. In addition, that lump of lead will also give him internal injuries at the level of broken ribs... If poison is applied to the tips of the steel nails, then it will be 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 the defense as a whole, penetrate the human body, and stir the internal organs - KO...
