please make me king

Chapter 1107

"Your Highness King Shun, the new type of blunderbuss is ready, please try it out!" Several craftsmen offered two firecrackers.

Although one is long and the other is short, these two firecrackers look almost the same from the outside, just like the same mother.

This is exactly the new type of one-two fire blunderbuss designed by Zhang Shun.

Both have the same structure, both have a caliber of [-]mm, and use one or two lead bullets.

It's just that one barrel is long and the other is short, which are used as rifles and horsebacks respectively.

"What is the length and weight of these two guns?" Zhang Shun grabbed the riding gun first, and opened his mouth to ask while examining the appearance in detail.

"The short one is the riding blunderbuss, with a tube length of two feet and a total length of three feet and two inches. It weighs five catties and six taels. If you add the gun belt, stick, matchlock, gunpowder and other items, it is also under six catties." The blacksmith in charge Can't help hastily answered.

"The elder is a rifle, with a tube length of three feet and eight inches, a total length of five feet and one inch, and a weight of eight catties. If you add the gun belt, stick, matchlock, gunpowder, etc., it will only weigh eight or nine pounds."

"These two firecrackers have been released many times, absolutely foolproof!"

Just kidding, if the firecracker delivered to King Shun exploded, would my whole family not want it?
"The body of King Shun's daughter, how can you try to shoot this, why don't you let me do it!" Ma Yingniang immediately stood up and said.

Too bad, let this woman take the lead!

Hong Niangzi and Wang Qiying looked at each other, and they couldn't believe that these blacksmiths had the guts to take out unqualified firecrackers for Zhang Shun to test fire.

"No need, I'll do it!" Zhang Shun checked for a long while, but didn't find anything suspicious before deciding.

Ma Yingniang was taught by Zhang Shun, how could she be trusted?

Zhang Shun stretched out his hand and pulled out the stick, followed the steps to clean the barrel, and then began to pour gunpowder and lead.

After filling it in a short time, he clamped the lighted matchlock on the dragon head, then put the riding gun on his shoulder, and aimed at the target fifty paces away according to the requirement of "three points and one line".

Since the barrel of the riding blunderbuss is short, it cannot be as accurate as the bird blunderbuss and Lumi blunderbuss, so the distance of [-] steps has been reduced.

"Bang!" Zhang Shun quickly closed his eyes while grabbing the trigger.

The matchlock guns of this era are very cheating. When the primer is ignited, a flame will shine and hurt the shooter's eyes.

Therefore, the gunner needs to aim in advance, and then close his eyes at the moment of firing, so as not to affect his vision.

Because of this, some musketball players will blindly close their eyes and need to go through strict training and strict "discipline" to ensure the hit rate.

The dragon head riding the blunderbuss held the lighted match, and it fell into the medicine pool at once. He only heard the sound of the blunderbuss, and Zhang Shun felt a strong force coming from him.

It was like being punched by someone, if Zhang Shun hadn't been in the military for many years, he would have made a fool of himself this time.

"This guy has quite a temper!" Zhang Shun couldn't help but opened his eyes and shook his head, laughing at himself.

"Hit the target, the armor piece has been penetrated!" A soldier had already reported the target and ran over holding the armor piece taken from the target.

"King Shun didn't practice often, so it's inevitable that he won't get used to it." Wei Congyi quickly helped him find an excuse.

Zhang Shun laughed, his family knew about his affairs.

It's not his specialty to wield knives and guns. The reason why he tried shooting himself this time is just to experience the power of the new firecrackers and to prepare for the improvement of future tactics.

"This can't be regarded as a penetration!" Zhang Shun took a look at the armor plate, and saw a dented piece at the edge, with a deformed lead bullet embedded in it.

Zhang Shun turned over and took another look, and couldn't help but wonder: "Is this lead deformed like this?"

"Lead is soft and iron is hard, so soft breaks hard, so it is like this!" Wei Congyi replied that Zhang Shun didn't know, and quickly explained.

"Lead is soft and iron is hard?" Zhang Shun was taken aback when he heard the words, and a flash of inspiration flashed in his mind, "That's right, no wonder the firecracker is so difficult to break through armor!"

When two objects collide, if one wants to damage the other, in addition to speed, it also needs a specific shape and hardness.

For example, the easiest way is to touch the steel arrow. In fact, it is to touch a little bit of fine steel on the armor-piercing arrow to increase the hardness.

This kind of armor-piercing arrow can't compare with the firecracker in terms of speed or kinetic energy, but it can also break through poor-quality iron armor for this reason.

For firecrackers, the shape of lead bullets cannot be changed, but the material can still be discussed.

"Tell me, how to replace lead bullets with iron bullets, will the armor-piercing effect be better?" Zhang Shun couldn't help suggesting.

"Usually iron bullets are used for cannons, but not guns!" Wei Congyi shook his head and said.

"One iron bullet is too light, two iron bullets hurt the gun, and three iron bullets are difficult to make so round."

The so-called "iron bullet is too light" is easy for Zhang Shun to understand.

The density of lead is higher than that of iron. Take the three-coin lead bullet commonly used in this era as an example. If it is replaced with an iron bullet, it will only have two lead, which is indeed a bit lighter.

But now that these two lead bullets are replaced by seven-dollar iron bullets, will the impact still be so great?
As for the iron bullets that hurt the blunderbuss, it is actually because the cast iron bullets have higher hardness and are easy to wear the inner bore of the blunderbuss.

Zhang Shun didn't plan to replace all of them with lead bullets, but in fact, it was nothing.

It's just that iron bullets are difficult to make round, but it needs to be tested.

It turns out that the melting point of lead bullets is low, so the general method of making lead bullets is to melt the lead lumps, then use a colander to drip the lead liquid, and let it form a round lead ball by itself under the condition of weightlessness.

If it is a large lead bullet, it can be poured directly with a mold, and then the burr is removed.

Although not as round as the former, the advantage is that the lead is soft and has little effect in the barrel.

"How about this." Zhang Shun couldn't help suggesting, "We can specially make some iron bullets for armor-piercing purposes."

"It's just that iron bullets are not as heavy as lead bullets, and gunpowder can be added to increase their power."

"Then...then it will be easy to explode!" The blacksmith reminded quickly.

"Explode the chamber?" Zhang Shun was taken aback when he heard the words, and suddenly remembered the matter of building the cannon back then, and couldn't help laughing.

"The barrel of this gun is too thick. To make it a little thinner, just wrap an extra layer of iron in the medicine room!"

When casting cannons, Zhang Shun discovered that when the firearms were fired, the part that received the greatest impact was the chamber.

It is completely different from what people of this era imagined. The impact force is many times that of other parts of the gun barrel.

Therefore, it is only necessary to strengthen the medicine chamber and lighten the gun barrel to achieve the effect of reducing the overall weight of the gun.

"This... can this work?" The blacksmith couldn't help asking in surprise.

"You just build it according to the law, and if there is a problem, I will blame it!" Zhang Shun couldn't help laughing.

The blacksmith had no choice but to go when he saw the "King of Qin" speak well.

Only then did Zhang Shun grab the rifle, threw it to Wei Congyi and said, "Come and help me try this, it's too powerful, I can't stand it!"

In fact, according to the kinetic energy formula, the recoil force is only related to the charge of the firecracker and the weight of the projectile.

Although the rifle has grown another foot and nine inches, the recoil has not changed.

How did Wei Congyi know all this?Hearing the sound, he tried shooting honestly.

Sure enough, this one-foot-eight-inch-long gun barrel was not in vain. It not only increased the muzzle velocity of the projectile, but also improved the shooting accuracy.

Wei Congyi was actually able to penetrate the upper armor plate when he shot the [-]-step target.

"Okay, okay, it's really a good gun!" Wei Congyi couldn't help but love it, completely ignoring its heavy weight and huge recoil, "It's a real magic weapon!"

"Where is this?" Zhang Shun smiled and said, "Actually, the short gun is not obvious, but the center of gravity of the long gun is a bit forward."

"After the blacksmith transforms it according to the method I said, it will be a real artifact!"
