As he spoke, he brought in a rectangular box from outside the door. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 ｉｎｆｏ

"General, please take a look."

Chen Xin took out a rifle directly from the box, this rifle was extremely strangely shaped, with an obvious flintlock hammer and a bolt-action locking mechanism, like a hybrid between two eras.

"The rifle has a rear load, inspired by the two-year infantry gun (modification), and adds a cover to the bolt that only exposes the ignition port, which moves with the bolt."

Chen Xin's mind immediately flashed the image of the "38 big cover", which really looked very similar, of course, except for the small opening that was exposed, the lid of the 38 big cover did not have an ignition.

"As with infantry guns, copper preloads were used, and gunpowder and lead bullets were wrapped in copper shells, and then sealed with something like beeswax or lard to keep the inside dry.

Goose fuse tubes were inserted into the ignition holes, and each gun could be equipped with a certain number of such copper reloads, increasing the rate of fire.

When it is time to shoot, pull the bolt and load the copper ammunition, be careful here, the ignition port should be manually moved to the far right, and then close the bolt, so that the bolt will jam the copper ammunition, and the cover on the bolt can also protect the shooter from being burned by the sprayed gunpowder.

After that, all you need to do is pull the hammer to get it to the firing position, aim, pull the trigger, pull the bolt, pull the copper cartridge case, load it with new ammunition, and so on. ”

After explaining, the technician looked at Chen Xin's silence for a long time, and asked in a low voice, "General, look, is this rifle ready?" ”

Chen Xin raised his head blankly and asked, "Who designed this?" ”

"General Qiyu is designed below."

Chen Xin gritted his teeth and said the code that was known to almost the people of the whole country in later generations, "Heavenly King Covers the Tiger." ”

Looking at the other party's blank eyes, Chen Xin then asked, "What year did you cross over?" ”

"Dare to ask the general, what is crossing?"

"Lao Bai, has the personal medical terminal detected any obvious changes in the other party's heart rate?"

"Report to the host, the other party is fine."

"Whew." Chen Nobunaga breathed a long sigh of relief, it was good that it wasn't another traverser, if there were really other traversers, he really didn't know what to do. "Nothing, I said it casually."

Turning his attention to the rifle, he pulled the bolt, except that there was no firing pin and magazine, it was really no different from a bolt-action rifle, and he looked at the chamber and saw that there was no ammunition.

Then check it in turn, there is no rifling in the muzzle, it seems that it is still a smoothbore gun, combined with the theory that the smoothbore gun used by the other party before, Chen Xin knew that they also used Minne bullets on the copper loading ammunition of this rifle.

Asked, "What is the effective range of this rifle?" ”

"The test gunner we selected from the army used to use round lead bullets for more than a year, and the 200-meter humanoid target could achieve a score of 3 out of 10, which is already a top-class shooter, but after switching to this rifle and being proficient for a period of time, he scored 10 out of 10 on the same 200-meter humanoid target."

"Sss There was a sound of inhalation in the corner of the room, and it was the staff officers who were shocked, and their heads had improved so much that it was beyond their imagination.

The technician looked up proudly, his eyes twinkling, and continued, "After getting familiar with the ballistics and installing the ruler, the tester has been able to easily hit the fixed at a distance of 300 meters." ”

A staff officer couldn't help but interject and asked, "What about the specific achievements?" ”

The technician pretended to be calm, "Hitting a 300-meter fixed target is, of course, 10 out of 10, which is not the most amazing, the longest distance is to shoot at 400 stationary targets, but the accuracy is much lower at this distance, and only 7 shots can be hit in 10 rounds." But the upturned movement of the corners of his eyes betrayed his heart.

At this moment, even Chen Xin was taken aback, without rifling, he could accurately shoot a 400-meter humanoid target, or 7 out of 10, more than half of the probability, how could it be possible?

Although the tester was a first-class marksman, and it must have been a lot of shooting training with a new rifle, and he had practiced good marksmanship for a long time.

However, Chen Xin still felt that it was too exaggerated, you must know that without rifling, the bullet was more than 200 meters out of the chamber, and it began to roll when it was less than 300 meters, how could it be possible to hit the target at 400 meters.

Chen Xin, who was a little incredulous, took out a copper piece of ammunition from the box, took out a dagger to open the seal, and poured out the lead bullet inside.

Sure enough, this is not the Mingne bullet that he drew in the ordnance factory at all, but only borrowed the shape of the second half of the Mineer bullet, and the front half is completely redesigned aerodynamic shape.

Chen Xin took the bullet and asked, "How did you choose this shape of bullet?" ”

"General, we recruited and trained a large number of people with excellent eyesight, and then selected the best place to build a shooting range, so that these people used binoculars to constantly check the trajectory of various shapes of ammunition in the air, and modified the records little by little, and finally selected this shape of warhead."

Chen Xin knew that although the other party said it easily, but things are definitely not simple, it is impossible for ordinary people to see the trajectory of the bullet with the naked eye, even if it is the era of black powder, the speed of the projectile is far from the speed of the rifle fired in later generations, but at least it is about 3 or 400 meters per second, I am afraid that the laboratory has also done countless experiments to find an observation method.

No wonder this rifle can achieve such a degree of accuracy, it is completely the hard work of hundreds of technicians, thousands of experimenters, and countless workers in the laboratory of the ordnance factory for more than a year.

Chen Xin praised, "You guys are doing a very good job, and I am very satisfied." ”

In later generations, the most common shooting distance for infantry in various countries was within 400 meters, and the farthest distance that the human eye could aim at was also at this distance.

This rifle is really good for your own equipment.

As long as the veterans who have undergone rigorous training can ensure accurate killing at 200 meters.

A handful of top shooters 300 meters.

Top scorer 400 meters.

Then his own troops are really the best in this era in terms of individual weapons.

Chen Xin asked happily, "Have you finalized this rifle?" ”

"It's finalized, but, General, there's one more thing."

"What's the matter? You say. ”

"After using the Mine bullet, we found that the original 18.5mm caliber seemed to be a bit too powerful, so we made several different caliber firearms, and you still need to decide which caliber to choose."

Chen Xin was stunned for a moment, and then reacted quickly, it was enlarged to 18.5mm caliber before, that was because the armor-piercing effect of the round lead bullet was too poor, and the lead bullet did not fit the barrel, and the air leakage was serious, so it could only be increased by increasing the caliber.

Now that there is an improved version of the Minne bullet, the fit of the ammunition and the barrel has been greatly increased, the air leakage has been reduced, the range and lethality have increased, and the same recoil has also increased.

However, the caliber issue is a big deal, after changing the caliber, not only the guns and ammunition production of the ordnance factory need to change a batch of molds, but also the soldiers also need to re-adapt to training, and now there are already tens of thousands of soldiers who need to replace this gun, and there may be more in the future, so be cautious.

The main thing, the lethality of small calibers, is a problem.

"What do you have suggestions for the Armory?"

"General, we tested various calibers, did a lot of comparative tests, and finally drafted a report on the application for the replacement of the caliber of the new generation of rifles, please take a look."

Chen Xin took the report and read it carefully, and the report elaborated on the various experimental methods adopted by the laboratory of the Ordnance Factory, and listed detailed data, the hit rate of various calibers against humanoid targets at different distances, and the damage effect.

Turning to the last page, the final conclusion is that the 11mm caliber has great lethality against people, and the hit rate against 400-meter targets is also the highest.

Chen Xin thought for a while and asked, "Have you calculated how long it will take for the whole army to install new rifles if the caliber is changed?" ”

"Well, we have calculated that with the current strength, it will take at least 1 year and 3 months, and this is not counting the militia and future expansion."

"So, have you calculated the lethality of 11mm for war horses?"

"I didn't specifically calculate it, but I happened to encounter a frightened horse near the school, and in order to protect the students from being hit, our spear tester used a new 11mm caliber rifle to shoot at the horse, and finally took a total of three shots to bring down the horse."

Chen Xin nodded: "Then do you know who our main enemy is?" ”

The categorical words came out of everyone's mouths "Houjin"

Chen Xin stood up, walked around the room, and said, "That's right, Houjin, whether we are carrying out sea trade, developing the army, or even this expedition to the Japanese Kingdom, it is all to enhance our strength, and finally fight with Houjin to the death."

The 18.5mm arquebus we use today is capable of knocking down the strongest horses with a single shot with round buckshot.

So now, you tell me, three shots can solve a frightened war horse, on the battlefield, how long does it take for Houjin's horse team to rush across a distance of 400 meters and come to our army?

How many times will we be able to shoot during this time? How many ineffective shots will there be in them? How much of an impact will this have on the fighters? ”

Sweat ran down the technician's forehead, "This, this, this, we actually made such a big mistake and almost got into trouble." General, we were wrong. ”

Chen Xin patted him on the shoulder, "No, you are not wrong, your rigorous scientific attitude is commendable, but the angle of thinking is different, after all, this is the brainchild of your more than a year, just like your children." It's normal that you want to be able to show the best of guns -- the best shooting accuracy of our time.

Occasionally open your mind and experiment with some unconventional projects to help the progress of science and technology, which can be regarded as technology storage.

However, in the future, you must focus on the development of weapons, and the performance of the weapon that the army needs most is the main direction of your experiment. ”

As he spoke, Chen Xin remembered the People's Liberation Army (PLA) in later generations, in China, which has a vast territory and complex terrain, the most important indicator of weapons is lightness, and the next indicator is the versatility of all climates and terrains (that is, endurance).

And now the most important individual weapon of his army is to be able to knock down Houjin's war horse with one shot at a sufficient distance, which is the most important weapon indicator at this stage, as for the future, it will not be possible to consider the future until Houjin is defeated.

"I understand, General, we will definitely listen to the army more in the future, so will this weapon still be produced?"

"Of course, we have to produce the assembly, but the caliber remains the same, and you can quickly produce enough barrels with the molds used to make barrels, how are you preparing for other parts molds? When will the whole army be able to change its clothes? ”

"If the caliber remains the same, we can make all the field troops use the new rifle within 2 months, but with the new gun, a large amount of copper will be needed, although each copper shell can be reused and loaded, but the copper material invested in the early stage is not a small amount, and the copper material in the inventory may not be enough."

Chen Xin thought about it in his heart and said, "I know, I will arrange to transport copper from the country as soon as possible." ”

"Well, General, what about a revolver? Need mass production? ”

Chen Xin thought for a while and asked, "How about the production speed of the revolver?" ”

The other party opened the backpack, took out a small notebook, looked at it for a while and said, "There are more parts of the revolver, and the size requirements are relatively high, which needs to be carefully polished, plus the caliber is reduced to 11mm, and the mold needs to be remanufactured, so the output can only reach 300 pieces per month, and more will require training of new workers and the purchase of new machines." ”

Chen Xin nodded, "Then Mr. will produce a batch of them, test the effect, and let the soldiers of the army evaluate its tactical value." ”

"So, General, does the caliber of the revolver need to be changed to the original 18.5mm?"

"Don't overdo it, the rifle has a butt to top, and you can get used to that kind of large caliber with more training, but the pistol doesn't have a butt, if you use such a large caliber, relying on the strength of the wrist alone, how can you keep the muzzle stable while firing."

"Yes, my subordinates know."
