Please ask me to be the emperor

"His Royal Highness King Shun, a new type of bird gun is ready, please try it out!" Several craftsmen held up two fire guns and offered them.

Although one is longer and the other is shorter, these two fire blunderbuss look almost the same in appearance, as if they are from the same mother.

This is the new type of one or two fire blunderbuss designed by Zhang Shun. The shorter one is a riding blunderbuss and the longer one is a walking blunderbuss.

Both have the same structure, the caliber is 5/8 centimeters, and they use one or two lead bullets.

It's just that one gun tube is long and the other is short, which can be used as a walking gun and a riding gun respectively.

"What's the length and weight of these two guns?" Zhang Shun first grabbed the riding gun and asked while inspecting the appearance in detail.

"The short one is a riding gun, with a tube length of two feet, a total length of three feet and two inches, and a weight of five kilograms and six taels. If you add the gun belt, stick, match rope, gunpowder and other items, it will be less than six kilograms." The blacksmith in the lead. He couldn't help but responded quickly.

"The elder is a walking gun. The tube is three feet eight inches long, the total length is five feet one inch, and it weighs eight kilograms. If you add the gun belt, stick, match rope, gunpowder and other items, it only weighs eight kilograms or eighty-nine taels."

"These two fire cannons have been released many times and are absolutely foolproof!"

Just kidding, if the gun delivered to King Shun explodes, will your whole family be killed?

"King Shun has a body of thousands of gold. Why don't you try shooting this? Why don't you let me do it!" Ma Yingniang stood up and said after hearing this.

Damn it, this bitch got the upper hand!

Lady Hong and Wang Qiying looked at each other. They didn't believe that these blacksmiths had the guts to take out substandard fire guns and let Zhang Shun test-fire them.

"No need, I'll do it!" Zhang Shun decided after checking for a long time and finding nothing suspicious.

Ma Yingniang's gun skills were taught by Zhang Shun, how could she be trusted?

Zhang Shun reached out and took out the stick, cleaned the gun chamber according to the steps, then began to pour gunpowder and load lead.

Not long after he finished loading, he clamped a lit match rope on the dragon's head, then put the musket on his shoulder and aimed at the target fifty steps away according to the "three points and one line" requirement.

Because the barrel of the riding gun is shorter and cannot be as accurate as the bird gun and Lumi gun, the distance is reduced by thirty steps.

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

The matchlock guns of this era were very tricky. When the primer was ignited, they would sparkle with fire and hurt the shooter's eyes.

Therefore, the gunman needs to aim in advance and close his eyes at the moment of firing to avoid affecting his vision.

For this reason, some fire gunners will shoot blindly with their eyes closed, and they need to ensure their hit rate through strict training and strict discipline.

The dragon's head of the blunderbuss held the lit match rope, and it suddenly fell into the priming pool. There was only a sound of the blunderbuss, and Zhang Shun felt a strong force coming from it.

It was like being punched. If it weren't for Zhang Shun's many years of military career, he would have made a fool of himself this time.

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

"Hit the target, the armor plate was penetrated!" A soldier had already reported the target while running over holding the armor plate taken from the target.

"King Shun doesn't practice often, so he is inevitably a little uncomfortable." Wei Congyi quickly helped him find an excuse.

Zhang Shun laughed, his family knew their own affairs.

Dancing with swords and guns was not his specialty. The reason why he personally tried firing this time was just to experience the power of the new fire gun and to prepare for improving future tactics.

"This can't be considered a breakdown!" Zhang Shun took the piece of armor and looked at it. He saw a dent in the edge and 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 the softness breaks the hardness, that's why!" Wei Congyi replied that Zhang Shun didn't know and quickly explained.

"Lead is soft and iron is hard?" Zhang Shun was stunned when he heard this, and an idea flashed in his mind and said, "Yes, no wonder it is so difficult for fire guns to break armor!"

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

For example, the simplest way is to point a steel arrow. In fact, it is to add a little bit of fine steel to the armor-piercing arrow to increase the hardness.

This kind of armor-piercing arrow cannot compare with the fire gun in terms of speed or kinetic energy, but it can still break through lower-quality iron armor. This is why.

For fire guns, the shape of the lead bullet cannot be changed, but the material can still be said.

"Tell me, how can I replace the lead bullets with iron bullets? Will the armor-piercing effect be better?" Zhang Shun couldn't help but suggest.

"Generally, cannons use iron bullets, but not muskets!" Wei Congyi shook his head and said.

"The first thing is that the iron bullet is too light, the second thing is that the iron bullet hurts the gun, and the third thing is that the iron bullet is difficult to make so round."

Zhang Shun can easily understand the so-called "iron bullet is too light".

The density of lead is higher than that of iron. Take the three-cent lead bullet commonly used in this era as an example. If it were replaced by an iron bullet, it would only have two lead, which is indeed a bit light.

But now that these two lead bullets are replaced by seven-cent iron bullets, will the impact be that big?

As for the iron bullets that damage the blunderbuss, it is actually because the cast iron bullets have a higher hardness and tend to wear the inner bore of the blunderbuss tube.

Zhang Shun doesn't plan to replace all his weapons with lead bullets. In fact, this is nothing.

It's just that it's difficult to make a round ball with an iron bullet, but it needs some experimentation.

It turns out that lead bullets have a low melting point, so the general method of making lead bullets is to melt the lead mass, then use a colander to drip the lead liquid, allowing it to form a round lead ball on its own without weight.

If it is a large lead bullet, it can be poured directly into the mold and then the burrs are removed.

Although it is not as round as the former, it is better because the lead is softer and has less impact on the barrel.

"Let's do this." Zhang Shun couldn't help but suggest, "We can specially make some iron bullets specifically for breaking armor."

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

"Then...then it will be easy to explode!" The blacksmith reminded him quickly from the side.

"Exploding the barrel?" Zhang Shun was stunned when he heard this, and suddenly remembered the matter of building the cannon, and couldn't help laughing.

"This barrel is too thick. To make it a little thinner, I just need to wrap an extra layer of iron in the medicine chamber!"

When he was casting artillery, Zhang Shun discovered that when the firearm was fired, the medicine chamber received the greatest impact.

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

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

"Is this...is this possible?" the blacksmith asked in surprise.

"Just build it like this, and if anything goes wrong, it's mine!" Zhang Shun couldn't help but laugh.

The blacksmith saw the "King of Qin"'s golden words and had no choice but to go.

Zhang Shun then grabbed the gun, threw it to Wei Congyi and said, "Come and try this for me. It's so strong that I can't stand it!"

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

Although this rifle is one foot nine inches longer, its recoil has not changed.

How did Wei Congyi know so much? After hearing the sound, he honestly tried firing.

Sure enough, this one-foot-eight-inch-long blunderbuss tube was not in vain for the blacksmith's efforts. It not only increased the muzzle velocity of the projectile, but also improved the shooting accuracy.

Wei Congyi was actually able to penetrate the armor plate while shooting at the target at seventy paces.

"Okay, okay, it's such a good gun!" Completely ignoring its heavy weight and huge recoil, Wei Congyi couldn't help but love it and said, "It's a real artifact!"

"Where is this?" Zhang Shun laughed when he heard this, "Actually, the short gun is not obvious yet, but the center of gravity of the long gun is a bit forward."

"When the blacksmith transforms it according to the method I told you, it will be a real artifact!"
