Back in mid-May.

Xujiazhuang, with Xu Yuan's purchase of a batch of equipment and raw materials related to weapon research and development from modern society, has been in place.

The weapons workshop in the workshop area was officially established.

Weapons research and development projects were also quickly established, and two weapons research and development and manufacturing teams were set up, and dozens of outstanding craftsmen were transferred, and two craftsmen with the best skills and the highest qualifications served as team leaders, each responsible for a weapons research and development project.

It's the end of May now, and it's been more than ten days.

On the morning of that day, Xu Yuan came to the weapons workshop and inspected the progress of the research on new weapons.

The first group of R&D workshops.

"Old Qian, how is the 'electric fire breech gun' project handed over to you progressing now? Did you make the first usable musket out there? ”

Xu Yuan found an old man in his fifties, with a strong body and strong spirits, and his hands were full of rough calluses, and when he saw him, he asked.

This old man's surname is Qian, his name is Shuangfu, he was born in a craftsman's household, has decades of old craftsmanship, is proficient in carpenters, blacksmiths, smiths, gold and silver engraving and other crafts, and has worked in the firearms workshop of the imperial court for several years, and has also studied firearms.

Xu Yuan, in order to show respect for this old craftsman, called him Lao Qian.

"Owner, according to your requirements, the first 'electric fire breech gun' was made a few days ago, but there are a number of flaws, not perfect, and it is still improving, and it has been improved to the No. 3 gun, which has solved most of the problems, but it has not yet reached the standard of stereotyped equipment."

Qian Shuangfu stroked the short beard of his chin and introduced Xu Yuan.

"Show me the No. 3 gun, can it be fired? Take me to the shooting range and give it a try. Xu Yuan's eyes lit up.

"Owner, this is the No. 3 gun, we have tested it more than 100 times, and the performance is basically up to standard, but you have a golden body, we will test the gun later, you can just watch from the sidelines."

Another craftsman in charge of testing took a 1-meter-long bolt-action breech rifle in the style of World War I, which was composed of a seamless alloy barrel, a wooden body, a metal canopy and a wooden butt, and handed it to Xu Yuan, and handed it to him for a closer look.

It weighs about 3 kg and is slightly heavy.

The internal structure is similar to that of the famous Mauser 98K.

It is a monolithic bullet composed of an aluminum alloy bullet case, a lead-tipped bullet, and a primer cap coated with Regon gunpowder, and the internal bullet is made of granulated black powder.

After firing, the cartridge case is manually ejected using a bolt.

Then clean the chamber of the gun from the residue of gunpowder combustion.

Push the bolt again to start firing the next bullet.

Because the traditional black powder with low detonation velocity is used, the chamber pressure is not high, the muzzle velocity of the bullet is about 320m/s, the maximum effective range is about 1000 meters, and the heavy armor can be broken within 500 meters, and within 300 meters, as long as the torso part of the person who is shot is injured, with the medical level of this era, it is basically impossible to get rid of the end of death.

The rate of fire is 5~10 rounds per minute, and as long as you go through formal and strict training, you can generally reach the level of 8 rounds per minute.

Of course!

The biggest difference of this breech bolt rifle is that it does not use a firing pin to hit the primer, but uses the battery to power up, which produces an electric spark fire, compared with the flintlock firing pin, the firing rate is nearly 100%, and the failure rate is extremely low.

Therefore, the tail wooden butt of this rifle not only has a small circuit, but also has three 1.5V No. 5 dry batteries, non-rechargeable type, which can probably meet the power requirements of 1000 shots.

But Xu Yuan did it on purpose.

The main purpose is to keep this rifle firmly in their own hands, and opponents and enemies, even if they get one or two through various means, will not last long, or because the bullets cannot be produced, or because the battery is exhausted, it will slowly be reduced to a burning stick.

Xu Yuan maintained his lead in this way, making the opponent unable to crack and catch up, and could only helplessly be at a disadvantage and passive, and there was no good way at all.

Because dry batteries are only available in modern society, it is almost impossible to completely bypass the traverser Xu Yuan.

"Bang!"

"Bang!"

"Bang!"

In the shooting range in the backyard of the workshop, a crisp gunshot rang out.

More than 100 meters away, Xu Yuan, who was holding a telescope, saw that the 3 mm thick steel plate had been pierced, and the entire pork fan placed behind the steel plate was full of holes; The silk cloth, cotton armor and iron armor that were put on the equal wood figures, with three layers of protection, were also completely penetrated; Several earthen pots the size of the night pot were also shattered, proving to be quite accurate.

"Ahem, cough, cough~"

The biggest problem is that the white smoke produced by the burning of black powder is very choking and obscures the line of sight, which seriously affects the accuracy of continuous shooting, which is a relatively regrettable flaw.

In addition, the aluminum alloy shell has a large wear and tear on the barrel, resulting in the service life of the barrel, which is about 2,000 rounds.

But no matter what, even if there are such and such imperfections, at least for this era, this 'electric fire breech gun' is an advanced thermal weapon that has been ahead of at least two centuries, and it has opened up several generations of differences, as long as it is handed over to a disciplined army to use, it can sweep away all opponents in this era!

"The No. 3 gun is already perfect, and then improve some places, conduct more shooting tests, and after all aspects of performance meet the standards, it will be officially finalized and mass-produced, and strive to equip it for the use of the guards within two months."

Xu Yuan instructed.

"Yes, owner."

"Now the raw materials are sufficient, and the processing machine is extremely easy to use, and two months is completely enough."

"But isn't it, those industrial machine tools, stamping, cutting, planing and drilling, cutting iron like mud, saving time and effort, extremely high efficiency, it is really an artifact, the old man can never go back to the past."

Qian Shuangfu and other craftsmen packed tickets with a confident face.

Followed by.

Xu Yuan went to inspect the R&D workshop of the second group next door, and saw the person in charge, Sun Datie - a middle-aged man in his early forties with muscles and muscles, with a rough face, like a pig killer, but in fact he is a thick and fine person, and his iron-making skills are also very exquisite, with high understanding, and some modern forging processes, only he can quickly master them, and Xu Yuan also values him very much.

"Team Leader Sun, how is the development task of the 'White Sugar Grenade' I gave you? Recently, Zhuang Li has heard the sound of explosions coming from the workshop area every day, and it is getting louder and louder day by day, so I must have found the best dispensing ratio and quickly took out the most powerful sugar grenade, right? ”

Xu Yuan asked with a smile.

White sugar grenades?

What kind of weapon is this?

In fact, on the basis of ordinary black powder, an appropriate amount of white sugar is added, so as to increase the explosive lethality of black powder.

As long as you find a way to create a high-temperature environment, and then let the saltpeter react with white sugar in large quantities, then the power of the explosion will be quite amazing, almost raising the power of black powder to a big level.

It's just that the difficulty in the development of sugar grenades is the specific ratio of ingredients, which requires a large number of explosion experiments to find the most powerful formula little by little.

Once the weapon is developed.

In the early stage, you can set up a special grenadier, use sugar grenades to bomb wildly, and kill a large area of the kind when you explode, and for the enemy who has paid heavy casualties and waded through the rain of bullets, it will only meet a heavier blow and fall into a nightmarish hell.

It can also be used in melee scenarios such as castle defense, urban street fighting, and night raids.

In the later stage, on the basis of the sugar grenade, a mortar, with a longer range and greater power, has more charges in the shell, and the firing range can reach up to one or two kilometers, and it is light and easy to carry, with high accuracy, much stronger than the red cannon, which is a very good artillery weapon, and even in modern society, mortars have not been eliminated.

"It's almost successful, but I don't think it's powerful enough, it's not fun to blow up, I'll try to call up the most powerful formula, and better protect our Zhuangzi in the future, and blow up those corrupt officials and corrupt officials!"

Sun Datie said in a thick Shaanxi accent that he had great resentment and hostility towards corrupt officials after fleeing from Shaanxi.

"Alright, that's almost it, give you another month to confirm the best ratio of explosives, and then start mass production of sugar grenades. The newly recruited Guardians, but waiting for these weapons you have made. Xu Yuandao.

"Don't worry, owner, I won't delay things!"

Sun hit the iron and slapped his chest to reassure.

Xu Yuan nodded, didn't look at the effect of the grenade's explosion test, left the weapons workshop, and ended today's inspection.
