The people of Shen Shu have spoken, and of course the soldiers of the Daye Battalion must carry it out immediately.

Zuo Zixiong personally conveyed that the two battalions of Lu Datou and Wang Deren each selected hundreds of elite musketeers who had been trained for a long time, and received a batch of the latest firearms that Song Yingxing had just made last month, and then began to demonstrate in formation.

As mentioned earlier, the seven battalions on Daye's side, and the three battalions under the staff general Zhu Wenzhen, who was withdrawn from Liaodong, were all garrisoned by the old men of the Huangzhou army.

Now that Lu Datou and Wang Deren have got the opportunity to perform, the only remaining Liu Sandao is a little embarrassed. He also knew that he was a thief and a general, or he killed his father-in-law to vote, and his credit was not obvious at present, and his trust was not as good as the other two, so he had nothing to say.

can only hope that the follow-up will be stained with a little more blood of other thieves, further clear his position, and become a descendant.

Fortunately, this time the Shen family army also got two new firearms, so it is reasonable to pick two battalions and test one of them in each battalion, and it is indeed impossible to use more people.

In a few moments, the 600-reloaded short-barreled trolls, and the 200-shot shorter-barreled trolls, were allotted, and the musketeers were all lined up, ready to shoot.

In addition to the muskets assigned to the soldiers, several of each were presented to the Sinking Tree Man for him to personally inspect and admire.

The Sinking Tree Man stroked the two muskets and asked casually, "How long is this production?" ”

Zuo Zixiong hurriedly replied: "About a month's output each." This longer, double-barreled breech-loading musket is more difficult to produce than the Rumis gun, and can produce about three-quarters of the capacity.

Since the beginning of March, I heard that Mr. Song's workshop has stopped the traditional Lu Mi gun and made every effort to switch to the production of this new gun. Originally, the production of the Lumi and Bird guns could be expanded to 800 per month, but this new breech-loading gun could only produce 600 guns.

The kind with a runner is even more complicated, and can only produce two or three hundred rods at the same time. It only began to move to mass production at the beginning of this month. ”

After hearing this, Shen Shuren was a little surprised.

It was also true that the revolver was built so slowly, and he had no doubts about this speed,

But the production speed of the rear-loading trolls was already faster than he expected - because he clearly saw that the trolls in front of him were already a kind of double-barreled spray close to the later S686 or double-barreled shotguns. The difference is nothing more than that the rifle process and materials are much worse than those of later generations, and the air tightness and processing accuracy are too poor, and the wax shell bullet is used.

"This breech-loading musket has two barrels, and it can produce 600 guns a month? Wouldn't the amount of work required for barrel processing be twice as high as for a single-barreled gun? This is probably also influenced by the three-eyed gun, right? Shen Shuren looked at the structure of the opening and closing of the rear of the barrel and couldn't help but ask.

Zuo Zixiong was obviously curious about this issue at the beginning and did research, so now he can learn and sell now:

"The last general was also worried about this problem at first, but later asked Fang Futai and Mr. Song to confirm. Although this gun needs to process two pipes, it is shorter than half after all, and it is still built with low bore pressure and using the coiling method, not the long-tube drilling method.

Therefore, when producing, you can directly roll a long one, cut it in half from the middle, and then polish off a small section of the deflated deformation during cutting to form two.

Listening to Mr. Song, he was indeed influenced by the idea of the three-eyed gun, but after all, the three-eyed gun is front-loaded, and it can't be reloaded in wartime, and it's useless after fighting, so he can only fight in close combat. This one is rear-loaded, and can be reloaded with a round of retreat.

Mr. Song also tried to directly put on the three tubes at the beginning, but when the three tubes were unloaded and loaded in the rear, the barrels were not easy to pout, and the zigzag arrangement was arranged on the top tube, which had particularly poor air tightness and a particularly large gap. When firing, more than half of the gunpowder gas leaked out, and even sprayed on the shooter's face, burning people, so he gave up.

Only two tubes are left, arranged in parallel to the left and right, and there is no problem of the barrel farther away from the shaft and tenon at the tail of the barrel, and the gap is larger.

Moreover, the firearm made by the coil pipe method was originally reinforced with an iron hoop on the outside, but now since it is a double-barreled gun, two pipes can be hooped together with the same batch of oval iron hoops.

Mr. Song also tried to weld and cast the reinforced joints on the outside of the hoop double tubes, and just put the two gaps between the barrels of the coiled barrel face to face and face to the inside, so that the risk of exploding the bore can be further reduced. ”

After listening to these explanations, Shen Shuren was also amazed, but he didn't expect Song Yingxing to come up with such an ingenious way to avoid weaknesses.

The biggest problem with the coiled pipe method is that the strength of the rolled seam will be low, which is much lower than that of seamless steel pipes. However, when the two barrels are side by side, the gap is pressed together, and some more metal is poured and welded up and down, which can not only connect the two pipes closely side by side, but also strengthen the strength of the gap between the coiled pipes at the same time, and obtain double compression, which can be described as killing two birds with one stone.

I didn't expect the gun of the coil method, resulting in a double-barrel side-by-side, and such an additional benefit. Shen Shuren didn't expect it at all, he thought that the appearance of double-barreled shotguns in later generations was purely to increase the density of firepower.

After understanding the principle clearly, he asked people to take a ruler to carefully measure and verify it, and sure enough, the length of the tube of this obviously short-barreled double-barreled gun was more than half shorter than the original Lumi gun.

The traditional bird gun and the Lumi gun are all five feet long, and considering the length of the butt and some other firing parts, the barrel is actually only four feet long.

The double-barreled spray in front of him, each tube is only one foot eight inches long, and after the barrel is shorter, the total amount of ammunition has also decreased, and it seems that the overall size of the wax shell bullet is smaller than the original paper shell bullet, and it is also a little shorter.

Shen Shuren looked thoughtfully at a wax shell bullet in his hand, crushed it very expertly, and carefully sorted out the small lead beads and gunpowder in it. After a simple visual inspection, he found that the lead ball projectile component of this new ammunition has not been reduced, but only the propellant has been reduced, and the visual inspection is only two-thirds of the original bird gun propellant, which should be to reduce the chamber pressure-

Song Yingxing's side estimated that he had also calculated and repeatedly conducted comparative experiments. Because the barrel is short, it is wasted to reload so much medicine, and the time for the projectile to fly forward by one foot and eight inches is simply not enough for the original full charge of so many drugs to fully burn.

After reducing the gunpowder, the leakage caused by incomplete sealing of the gun tail can also be slowed down, so that too much fire will not be spewed.

There's not much to say about it, it's just like a submachine gun that has to be loaded with a pistol. It is a reason that the charge is much smaller than that of rifles and machine guns.

Shen Shuren threw away the bullet fragments and clapped his hands: "Then let's test fire first, and see if two-thirds of the charge can be fully burned." ”

Zuo Zixiong received the order and immediately asked the 600 people under Lu Datou to line up neatly, pick up the short barrel and load the gun, and take turns to fire in batches and test fire. For a time, there was a lot of gunfire in the shooting range, and thick smoke billowed from the flames.

The Sinking Tree Man frowned, and looked closely through his binoculars, and it seemed that the muzzle flames and smoke of these muskets were about the same size as the original birds.

Shen Shuren has common sense of physics and chemistry, and knows whether the burn is sufficient from the muzzle flame. The muzzle of the gun was not significantly larger than that of the original bird, which means that the reduction of the charge was very reasonable, and did not lead to more gunpowder "burning after discharge, ineffective burning".

It's just that the first time I saw a large-scale salvo of rear-loading guns, the fire and smoke leaking from the reloading gap at the tail of the barrel still shocked Shen Shuren.

He saw that many of the soldiers did not dare to hold their guns close to their faces and aim accurately, and many held their guns up a foot away from their faces. As for closing their eyes at the moment of firing, there is nothing to spray, because at that time, all musketeers had to close their eyes at the moment of firing, otherwise they were likely to be blinded by the flames.

What makes Shen Shuren unacceptable is that not only do some soldiers close their eyes, but some of them even turn their heads, and there will not be much body movement when they close their eyes, and turning their heads will definitely make the shooting action out of shape, and the previous aiming will be completely in vain.

"This is not good, how can you allow a soldier to turn his head when he fires? Even if the tail of the barrel leaks smoke and fire, you can't turn your head! It is also necessary to strengthen the discipline and overcome the fear! In addition, consider adding leather visors to the helmets and leather armor of non-commissioned soldiers with new rear-loading guns in the future! Don't be afraid to blacken your face! ”

While reprimanding, Shen Shuren also wanted to set an example and try to shoot it.

Of course, Shen Shuren is a person who is noble and in a high position after all, and there are so many beauties waiting for him to be pampered, his face must be blackened and he can't bear it, his handsomeness is very important.

So he took a short gun with a tube of only one foot eight inches and a total length of about two feet and four inches, held it in one hand and raised his arm flat to aim, wanting to see if he could hold the gun in one hand and make sure that the tail of the gun was at least an arm's length from his face when aiming.

But for just a second, he felt that his arm was so sore that he couldn't aim at all. It seems that a gun of this weight is still a little difficult to use as a carbine for cavalry one-handedness, during the charge, and before engaging the enemy.

Zuo Zixiong looked at Shen Shuren's operation, and was slightly surprised, this kind of gun had just come out, and the Shen family army had not carried out cavalry cavalry and archery drills, and it was still for infantry to shoot first, so it was true that the soldiers had not tried to use it with one hand.

Fortunately, Zuo Zixiong had rich experience on the battlefield, and soon realized Shen Shuren's purpose, and patiently asked: "My lord, do you think that when you shoot with both hands, the tail of the gun is too close to your face?" So I want to see if this short gun can be used by the cavalry?

In that case, it would be better to switch to the revolver, the barrel of the revolver was further shortened, only one foot two inches, and only a single barrel, the front part weighed only one-third of this gun, and it could be held flat and aimed in one hand.

This kind of double-barreled gun, although it is only one foot and eight inches, can have two tubes at the same time, and it is still too heavy to lift it with one hand.

However, the last general figured out a way to use it, which had to be used on horseback by cavalry, so he could only give up aiming, clamp one hand under his armpit, hold the tail of the gun with the inside of his elbow, and only lift the gun up with his wrist. ”

Shen Shuren was right when he thought about it, and hurriedly gave up "one-handed aiming and shooting" and changed it to "one-handed waist shooting", so that he didn't need too much strength, after all, a section of the person's arm naturally formed a lever, and the torque generated by the gravity of the gun was greatly reduced.

Moreover, after hip shooting, the horizontal distance between the tail of the gun and the human face is about half an arm, or the distance of a forearm, and the distance in the vertical direction is equivalent to the upper arm of a person.

Therefore, the straight-line distance from the tail of the gun to the human face should be about twice the length of the forearm of the root number, which is about 30% closer than the lifting level, which is still acceptable and will not burn the black face.

Shen Shuren cautiously shot two rounds from the waist, except that he was not very stable, there was nothing else wrong, and his face was not blackened at all.

"Yes, it's very good, in the future, this kind of double-barreled gun will train the cavalry to shoot at the waist on horseback, without aiming, that kind of revolver, for the cavalry to charge and aim and shoot on the horse.

In this case, the armor of the musketeers should also be improved, and they should wear better wrapped arms that do not conduct heat, and the ribs on the waist should also be strengthened, so that the rifle is held on the elbow and clamped to the waist to shoot, so that the flames leaking from the breech will not burn the arms. ”

This kind of treatment, of course, will not be used for sealed breech guns in later generations, but Shen Shuren, an inferior product that will leak fire at the end of the barrel, has to be considered.
