In November of the thirteenth year of Chongzhen, the firearms test range of the Jiangnan Ordnance General Bureau of Taiping Prefecture.

Zhu Cihong attaches great importance to the development of the military industry, and the first stop of the tour came to the Taiping Mansion, at this time he gathered the main personnel of Sun Heding and other research institutes.

Today's military research institute is full of talents, there are thousands of scientific research personnel, most of them are composed of old craftsmen, Zhu Cihong rewarded scientific research projects with a lot of money, so that the institute is full of vitality, and the craftsmen's enthusiasm for research and development is extremely high.

The craftsmen conducted a lot of experiments in order to develop weapons, and several craftsmen were killed on the spot, and some were mutilated with broken arms and legs.

Zhu Cihong did not treat them badly, and the sacrificed craftsmen each had thousands of acres of official land and 10,000 taels of silver as a pension, and the disabled were also comforted by at least 1,000 acres of fertile land and thousands of taels of silver, ensuring that they would have no worries about food and clothing for the rest of their lives.

Driven by this pension policy, craftsmen work harder and harder, and once they develop advanced equipment, they will have more abundant rewards.

At the test range, ten sergeants stood a hundred paces away from the target target with heavy muskets in their hands, and a row of bullets was placed on a long iron table in front of them.

The new musket was developed by Sun Heding after four years, and it is almost the same as the historical Mini rifle, the whole gun weighs nine and a half pounds, the caliber is almost 20 millimeters, each bullet weighs six dollars and five cents, and is also equipped with a safety lock to prevent misfire.

The flint hair Lumi gun equipped by the Tianwu Army weighs about seven or eight catties, is about six or seven feet long, uses four coins for medicine, and three coins for lead bullets, and the body and lead bullets are far heavier than the arquebus, but compared with Sun Heding's new musket, it is a cut worse.

Zhu Cihong asked Sun Heding to develop rifled guns four years ago, although he made a batch, but he has never been able to solve the shortcomings of the slow loading speed of rifled guns, slow loading speed means that it is impossible to form a continuous fire strike, even if the range and accuracy are far greater than the flintlock Lumi gun equipped by the Tianwu Army, it cannot be popularized and equipped with the whole army, and can only be used as a sniper rifle by the sniper brigade.

Through hundreds of research experiments, Sun Heding finally overcame the problem of slow loading speed of rifled guns, and he created a new type of lead bullet with a round head and cylindrical shell.

The original rifled gun barrel is engraved with rifling, and it is difficult to keep the chamber closed in front of the bullet, and the power is greatly reduced, in order to achieve good air tightness, the caliber of the rifled gun bullet is often made to be flat or even slightly larger than the gun caliber, so when loading, it is necessary to use a push lever to advance the bullet into place, and the loading is extremely laborious, and the speed is very slow.

The new type of lead bullet developed by Sun Heding is a conical warhead, slightly smaller than the diameter of the chamber, so that it is very convenient to load, and there is a conical hole in the tail of the bullet, and a small round wooden plug to block the bottom of the hole.

In this way, when shooting, the gas presses the small wooden plug and squeezes into the cavity of the tail of the bullet, forcing the bottom of the lead bullet to expand and close to the rifling, sealing the gap between the bullet and the chamber, so that the gas cannot leak out, and can make the bullet rotate at high speed under the rifling pressure, increasing the range and accuracy.

The new bullet perfectly solves the difficulty of loading the front-loading rifled gun, greatly improves the loading speed, as long as the power, range and accuracy are stronger than the flintlock Lumi gun after the test, it will inevitably become the new equipment of the Tianwu Army.

Sun Heding patted his chest and reassured: "Your Highness, don't worry, this gun has been tested many times, and its power and accuracy are quite strong, with a lethality of up to six hundred steps, and an accurate hit rate can be guaranteed within three hundred steps!" ”

Xu Sheng exclaimed: "Master Sun, I haven't seen you for a few years, and you don't even blink your eyes when you talk big now?" Your Highness is no one else, you must not blow the air in front of Your Highness, I tell you. ”

The Tianwu Army's flint and reckless guns did not dare to guarantee the accurate hit rate of a hundred steps away, and Sun Heding said three hundred steps at once, which made the surrounding generals look sideways for a while.

Sun Heding slapped his chest and said, "If more than two of these ten guns can't have this effect, you will correct me in front of the army!" ”

Zhu Cihong smiled and waved his hand, "Let's get ready to test the gun." ”

He was not surprised at all, the historical Mini rifle has this powerful function, the Mini bullet is a very revolutionary invention in the history of bullets, although Zhu Cihong knows some, but he doesn't know how to do it, he can only tell Sun Heding what he knows and let him study.

Now that Sun Heding has been vacated, and he dares to swear a promise, it shouldn't be a big problem.

As soon as Sun Heding waved his hand, his assistant immediately shouted, "Everyone is ready, ready to test the gun!" ”

Ten sergeants took out new buckshot from the iron table in front of them, loaded them from the muzzle, and immediately took aim with their guns in a lying position.

There are three humanoid wooden targets on the test range, which are at 100 steps, 200 steps, and 300 steps.

When the sergeants took their guns and were ready, Sun Heding shouted, "Shoot!" ”

"Smack!"

Ten gunshots rang out at the same time, converging into a thick sound, and from this reaction speed alone, it could be seen that the ten sergeants who tested the guns were well-trained.

After three rounds of test firing of the ten rifles, the results stunned everyone, all the wooden targets of 100 and 200 paces were hit, and the wooden targets of one inch thick were all punched into a hole, and only one of the wooden targets of 300 paces was missed, and the other nine sergeants were all hit.

The eyes of several Tianwu generals who came with Zhu Cihong were excited one by one, this is simply an artifact, if the army of the Ming Dynasty can be equipped with such an artifact, if they encounter Tartars on the battlefield, their cavalry can send them to hell as soon as they appear!

Zhu Cihong said: "These ten soldiers who tried guns are all snipers. ”

The distance of three hundred paces is equivalent to four hundred and fifty meters, and the wooden target is a small point, even if the gun is good, it is difficult for ordinary soldiers to hit.

Sun Heding replied: "Your Highness is wise, these ten people are indeed transferred from the sniper brigade to test firearms, and it is rare for ordinary soldiers to take one or two hundred steps, and they cannot do accurate testing. ”

Zhao Jinglin, who was born as a sniper, took a gun from a sergeant, as if he was holding his little lover Li Xiangjun, and was amazed: "There is such a magical thing in the world!" Let me give it a shot too! ”

Xu Sheng said with a smile: "General Shenji is the number one marksman in the world, so he has to take four hundred steps!" ”

Sun Heding said with a smile: "This gun has been tested repeatedly, and the maximum range that can guarantee the hit rate is three hundred and fifty steps, and the trajectory beyond this distance cannot be mastered." ”

Zhu Cihong said: "Then try the four hundred steps." ”

Zhao Jinglin happily accepted the order, first held the gun and groped for a while to find the feeling, and then pre-heated the rake of 100 steps, 200 steps, and 300 steps, and the gun hit.

Zhao Jinglin prepared with a gun in the standard posture of a sniper, first looked at the surrounding environment, and then grabbed a handful of fine sand on the ground and gently raised it.

Xu Sheng was puzzled: "What is this for?" ”

A few generals around didn't understand either, and shook their heads one after another, although a few snipers understood something, but when the generals spoke, they couldn't interject casually.

Zhu Cihong said: "He is setting the wind direction and correcting the wind deviation, and when the wind speed exceeds a certain speed, it will cause the lead bullet to deviate from the original trajectory." ”

Although several generals didn't understand the specific principles, they could make do with it, and the ten snipers looked at Zhu Cihong with adoring eyes, and were deeply impressed by the omniscient crown prince.

Zhao Jinglin went through many tests, and when the wind speed became smaller and stable, he pulled the trigger on the wooden target 400 steps away.

A crisp sound sounded, and a soldier four hundred paces away ran over to look at it for a while, and immediately waved the small red flag in his hand.

Sun Heding exclaimed: "It's hit!" ”

Xu Sheng pulled Zhao Jinglin up, patted him on the shoulder and said, "He is worthy of being the number one marksman in the world, absolutely amazing!" ”

Seeing the effect of the new rifle, Zhu Cihong was very happy, with this powerful weapon, the difficulty of pacifying the world was greatly reduced, and after the new deal was completed and the provinces south of the Yangtze River were stabilized, he could raise troops to the north and pacify the Manchu Qing in one fell swoop!

In the future, you can also use this new rifle 200 years ahead of your time to fight Japanese devils, fight Russian Maozi, and do Western Hongyi.
