The Shenshu people had spoken, and of course the soldiers of Daye Camp had to execute them immediately.
Zuo Zixiong personally conveyed the message and asked Lu Datou and Wang Deren to select hundreds of well-trained elite musketeers each, receive a batch of the latest firearms that Song Yingxing had just made last month, and then began to line up for demonstration.
.
As mentioned before, the seven battalions on Daye's side and the three battalions under General Zhu Wenzhen who had withdrawn from Liaodong were all garrisoned by old men from the Huangzhou Army.
Now that Lu Datou and Wang Deren have both got opportunities to perform, the only remaining one, Liu Sandao, is a little embarrassed. He also knows that he is a bandit who was demoted to the general, or he killed his adoptive father to surrender, and his credit is not obvious yet.
, he is not as trusted as the other two and has nothing to say.
We can only hope to get a little more blood from other thieves in the future to further clear our position and become a direct lineage.
Fortunately, this time Shen Jiajun also received two new types of firearms, so it made sense to pick two battalions and test one of them in each battalion. There was really no need for more people.
After a while, six hundred short-barreled nozzles loaded with rear-loading guns and two hundred revolver nozzles with even shorter barrels were received and distributed, and the musketeers all lined up to prepare for target practice.
In addition to the muskets distributed to the soldiers, a few of each type were presented to Shen Shuren for him to inspect, play with and appreciate carefully.
Chen Shuren stroked the two types of muskets and asked casually: "How long is this production?"
Zuo Zixiong replied quickly: "The production is about one month each. This longer double-barreled breech-loading musket is more difficult to produce than the Lumi gun, and it can have about three-quarters of the production capacity.
Starting from the beginning of March, I heard that Mr. Song's workshop has stopped the traditional Lumi gun and switched to the production of this new gun. Originally, the production of Lumi gun and bird gun could be expanded to 800 guns per month. This new style
The breech-loading gun could only produce 600 shots.
The kind with a runner is even more complicated, and can only produce two to three hundred rods at the same time. It started mass production at the beginning of this month."
Chen Shuren was a little surprised after hearing this.
It was reasonable for the revolver to be built so slowly. He had no doubts about the speed.
But the production speed of rear-mounted spray guns has been faster than he expected - because he clearly saw that the spray gun in front of him was already a double-barreled spray gun close to the later S686 or double-barreled shotgun.
The only difference lies in the craftsmanship of the gun barrel. The materials are much worse than those of later generations, and the air tightness and processing accuracy are too poor. Wax shell bullets are used.
"This kind of breech-loading musket has two barrels, but it can actually produce 600 guns per month? Wouldn't the workload of barrel processing be twice as high as that of a single-barreled gun? This is probably also influenced by the three-eyed gun, right?
"Shen Shuren looked at the opening and closing structure at the back of the barrel and couldn't help but ask.
Zuo Zixiong was obviously curious about this issue at the beginning and did some research, so now he can learn and sell now:
"The general was also worried about this problem at first. Later, he came to Fangfutai and Mr. Song confirmed it. Although this kind of gun requires two tubes to be processed, it is more than half shorter after all. It still has low bore pressure and uses the rolling tube method.
It is built, not the long tube drilling method.
Therefore, during production, you can directly roll one long piece, cut it in half from the middle, and then polish off a small section that was flattened and deformed during cutting to form two pieces.
I heard from Mr. Song that he was indeed influenced by the idea of the three-eyed gun, but after all, the three-eyed gun is front-loaded and cannot be reloaded during war. It is useless after being fired and can only be used in close combat. This is rear-loaded.
You can quit and reload after a round.
Mr. Song also tried to directly load three tubes at the beginning, but the three tubes were unloaded at the rear. When loading, the barrel was not easy to stick out. The top tube arranged in a zigzag shape had particularly poor air tightness and gaps.
It was extremely large. When firing, more than half of the gunpowder gas would leak out and even spray on the shooter's face and burn him, so I gave up.
Only two tubes are left, arranged in parallel on the left and right, so there is no problem of a larger gap in the barrel that is far away from the rear axis of the barrel and the latch.
Moreover, firearms made using the rolled tube method originally had to be reinforced with iron hoops on the outside. Now that it is a double-barreled gun, the two tubes can be hooped together with the same batch of oval iron hoops.
Mr. Song also tried welding and casting to strengthen the connection outside the hooped double barrel, and just put the two gaps of the rolled barrel together face to face, facing inward, so that the risk of explosion can be further reduced.
"
After hearing these explanations, Shen Shuren was also amazed. He didn't expect Song Yingxing to come up with such a clever way to avoid weaknesses.
The biggest problem with the rolled tube method for making gun barrels is that the strength of the rolled joints will be low, which is much lower than that of seamless steel pipes. However, when two gun barrels are side by side, the gaps should be pressed together, and more pouring and welding should be done up and down.
By adding some metal, the two pipes can be closely connected side by side, and the strength of the gap between the coiled pipes can be strengthened at the same time to obtain double the pressure resistance, which can be said to kill two birds with one stone.
Unexpectedly, the roll-barreled gun resulted in a double-barreled side-by-side type, which would have such additional benefits. Chen Shuren never thought of it at the beginning. 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 someone to take a ruler to carefully measure and verify it. Sure enough, the tube length of this obviously short-barreled double-barreled gun was more than half shorter than the original Lumi gun.
Traditional bird guns and Lumi guns are five feet in length. Considering the length of the butt and other firing parts, the barrel is actually just four feet long.
As for the double-barrel gun in front of us, each tube is only one foot and eight inches long. After the barrel is shortened, the total amount of ammunition is also reduced. It seems that the overall size of the wax-cased bullets is smaller than the original paper-cased bullets.
It's a circle, and it's a little shorter.
Chen Shuren looked thoughtfully at a wax-cased bullet on hand, crushed it expertly, and carefully sorted out the small lead beads and gunpowder. After a simple visual inspection, he discovered that the lead beads of this new ammunition
The weight of the projectile has not been reduced, but the propellant has been reduced. Visually, it is only two-thirds of the original gunpowder propellant. It should be to reduce the chamber pressure——
Song Yingxing probably did the calculations and conducted repeated comparison experiments. Because the barrel is short, it would be a waste to load so much powder. The time it takes for the projectile to fly forward one foot and eight inches is not enough for the original full charge.
The multidrug is fully burned.
After reducing the gunpowder, the air leakage and fire leakage caused by incomplete sealing of the gun tail can also be slowed down, so that too much fire will not be sprayed out.
There’s not much to say about this. It’s just like the fact that submachine guns have low chamber pressure and need to use pistol ammunition. The charge capacity is much smaller than that of rifles and machine guns.
Chen Shuren threw away the bullet fragments and clapped his hands: "Let's test it first and see if two-thirds of the charge can be fully burned."
Zuo Zixiong received the order and immediately ordered the 600 people under Lu Datou to line up in order, pick up the short-barreled breech-loading guns, and take turns to fire in batches for test firing. For a time, there was loud gunfire in the shooting range, and flames and smoke billowed.
Chen Shuren frowned and looked carefully with a telescope. It seemed that the size of the muzzle flames and smoke of these muskets was similar to that of the original muskets.
After all, Shen Shuren has some knowledge of physics and chemistry, and knows how to judge whether the combustion is sufficient by looking at the muzzle flame. The muzzle flash is not significantly greater than the original gun, which means that the reduction in the charge is reasonable, and
It did not result in more gunpowder "burning only after exiting the chamber, burning ineffectively".
However, it was the first time he saw a large-scale breech-loading gun salvo, and the fire and smoke leaking from the loading gap at the end of the barrel still shocked Chen Shuren.
He saw that many soldiers did not dare to hold their guns close to their faces and aim accurately. Many of them raised their guns a foot away from their faces. As for closing their eyes at the moment of firing, there was nothing to complain about, because at that time all the musketeers were
You must close your eyes when firing, otherwise you may be blinded by the flames.
What Chen Shuren couldn't accept was that not only did some soldiers close their eyes, but some of them even turned their heads. Closing their eyes would not cause much body movement, and turning their heads would definitely distort the shooting action, and the previous aiming would also be distorted.
It's completely blank.
"This doesn't work. How can soldiers be allowed to turn their heads when firing? Even if the tail of the barrel leaks smoke and fire, they can't turn their heads! We need to strengthen training to overcome fear! In addition, consider giving helmets to soldiers who use new breech-loading guns in the future.
Add a leather visor! Don’t be afraid of blackening your face!”
While Chen Shuren scolded him, he also wanted to set an example himself and try to shoot.
Of course, after all, Shen Shuren is a noble man, holding a high position, and there are so many beauties waiting for his favor. It must be unbearable to have his face blackened. 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 four inches. He held it in one hand and raised his arm flat to aim. He wanted to see if he could hold the gun with one hand and make sure that the butt of the gun was at least at least away from his face when aiming.
There's an arm's length.
But in just one second, he felt that his arms were so weak that he couldn't aim at all. It seems that a gun of this weight is a carbine used by cavalry with one hand. It is still a bit difficult to fire before engaging the enemy during the charge.
.
Zuo Zixiong looked at Shen Shuren's operation and was slightly surprised. This kind of gun had just come out, and the Shen family's army had never conducted cavalry shooting drills. It was still for infantry's advance shooting training, so it was really not used.
Soldiers tried using it with one hand.
Fortunately, Zuo Zixiong had rich battlefield experience and quickly realized Shen Shuren's purpose, and asked patiently: "Sir, do you think the tail of the gun is too close to the face when shooting with both hands? So I want to see if this kind of short gun can be carried by the cavalry.
Use flat?
If that's the case, it's better to switch to that revolver gun. The barrel of the revolver gun has been further shortened, only one foot and two inches, and it only has a single barrel. The weight of the front part is only one-third of this gun.
It can also be held horizontally to aim.
Although this kind of double-barreled gun is only one foot and eight inches long, it has two tubes at the same time. It is still too heavy to lift flat with one hand. The general and some powerful generals in the army can lift it flat, but it is too difficult for ordinary soldiers.
.
However, the general has figured out a way to use it. If he has to use it on cavalry, he can only give up aiming, put one hand under his arm, hold the tail of the gun with the inside of his elbow, and his wrist is only responsible for lifting the gun up."
Shen Shuren thought right and quickly gave up "aiming and shooting with one hand" and changed to "shooting with one hand holding the waist". In this way, he didn't need to use too much strength. After all, one arm naturally formed a lever, and the gun
The torque generated by gravity is greatly reduced.
Moreover, after a hip shot, the horizontal distance between the gun tail and the person's face is about half an arm, or a length of forearm, and the vertical distance is equivalent to a person's upper arm.
Therefore, after calculation, the straight-line distance from the tail of the gun to the human face should be about twice the length of the forearm, which is 30% closer than the horizontal distance. This is still acceptable and will not cause a black face.
Chen Shuren carefully fired two shots from the waist. Apart from being unstable, there was nothing wrong with it, and his face was not blackened at all.
"Okay, very good. In the future, this kind of double-barreled gun will be used to train cavalry to shoot from the hip without aiming. The revolver gun will be used by cavalry to aim and shoot when charging on horseback.
In this case, the armor and stomach of the musketeers should also be improved. They should wear better-wrapped, non-heat-conducting arm guards, and the ribs on the waist should also be strengthened. In this way, the gun should be held on the elbow, clipped to the waist and fired, and the breech
The flames that escape will not burn your arms."
Of course, this kind of treatment was not used on the sealed breech guns of later generations, but it had to be considered for inferior products like Shen Shuren, which leaked fire from the rear of the barrel.
