Xia Nan understood what he meant: "Can I understand it this way, the biggest effect of a shrapnel is to hit a dozen cavalrymen approaching at high speed within a thousand meters?" Is it better to fight infantry with more stable and practical solid bullets and shotguns? ”

"That's right, you can use solid bullets to fight infantry at long distances, and shotguns to use shotguns at close range. The speed of the infantry is slow, it is too late to switch from solid bullets to shotguns, and there is no problem with the detonation rate. ”

"No wonder I haven't seen you on these pieces of equipment before, it turns out that the reliability and versatility are a little less interesting."

Lin Weiye spread his hands: "Therefore, throughout the era of smoothbore guns, it seems that solid bullets and shotguns with low technical content have always been the main force in land warfare, and grenades and shrapnel are only supporting roles. Of course, under certain conditions, the latter two can play a very good role. ”

After the grenade and shrapnel demonstration, the weapons for the finale appeared.

Lin Weiye held up a gun that looked similar to a Qionghai-style rifle and introduced: "The time is relatively urgent, instead of creating a rifled gun with a compressed caliber, I directly pulled the rifling on the basis of the smoothbore gun, and it is enough to demonstrate the principle of the rifled gun." ”

He took out a conical bullet that was different from traditional lead bullets, stuffed it into the barrel, and then pushed it forward with a bullet stick, raising the gun to aim at a tree two people high more than 300 meters away. After aiming for a long time, he pulled the trigger.

With a crisp gunshot, the trunk of the tree trembled obviously, and the leaves fell one after another.

"Damn, so powerful, can you hit so far?" Summer Minami gets excited.

Lin Weiye blew the smoke from the muzzle of the gun and said proudly: "This is only a modification of a smoothbore gun, and the firing range has shrunk, and the effective range of a professional, reduced-caliber rifled gun is close to 500 meters, which is even farther than this." ”

Xia Nan recalled: "I remember you said: rifled guns have rifling, bullets have to be embedded, loading is very difficult, and even small hammers have to be used to hit the pusher lever, why don't you use a hammer for this?" ”

"That's right, rifled guns have to have a small clearance between the barrel and the bullet, so that they fit closely and allow the bullet to rotate forward under the effect of spiral rifling, so that it can fly farther. If the clearance is too large, the bullet will not be able to spin. Hammers were standard in early rifled gun units. However, the appearance of Mini shells largely solved the problem of difficulty in loading rifled guns. ”

Lin Weiye raised a conical bullet, "Do you know the principle of the jungle tribe's blow arrows? The Minnie bomb was inspired by blowing arrows. See, a conical cavity is dug in the tail of the conical bullet, and then a wooden plug is inserted, and when fired, the gas compresses the wooden plug and squeezes into the cavity, forcing the bottom of the bullet to expand, close to the rifling, and close the gap between the bullet and the rifle, so that the gas cannot leak out, and the warhead can rotate at high speed under rifling pressure. With the support of this principle, the Mini bullet can be made slightly smaller than the barrel and does not require too precise clearance, so that the difficulty of loading is greatly reduced, and it is closer to a smoothbore gun. The firing range is four or five times higher than that of a smoothbore gun, and it can shoot wherever it is. ”

Xia Nan said a little depressedly: "Such a good thing, but you seem to have said that it can't be mass-produced......"

"Yes. There are several reasons that affect its mass production. First, precision. Although the requirements for clearance control are lower than those of other rifled guns, it is also relative, and it is difficult to ensure that the tolerances of the barrel and bullet are hand-built within a certain range. In other words, the barrels and bullets created by different craftsmen are not guaranteed to be interchangeable, and theoretically a gun can only be equipped with bullets made by the same craftsman......"

Xia Nan was speechless, a craftsman made guns and bullets, and could not operate on the assembly line, and the production efficiency could be imagined.

"The second reason, cost and longevity. Because the process is more complex, the cost of a rifled gun is about the sum of three smoothbore guns, although we have a lot of money and can ignore the cost problem, but the problem of service life cannot be avoided. After a certain number of bullets are fired, the rifling wears out, the accuracy and range gradually decrease, and in the end the effect is not as good as that of a smoothbore gun. The service life of a smoothbore gun of the same material can reach several times that of a rifled gun. To sum up, rifled guns and mini bullets are currently only suitable for a small number of elite troops, and the line infantry of the main force still has to use smoothbore guns, and the battlefield is always cheap NPCs are easy to form a scale! ”

"That's all there is to it." Xia Nan said depressedly, "So what troops are suitable for the Minny gun?" ”

"Personally, I recommend that the Guards Battalion, Special Operations Team and Marine Corps under construction be equipped with this weapon, and the equipment of the rest of the troops remains unchanged - these units are all special operations, and the ammunition consumption is far less than that of ordinary line infantry, even if the guns and ammunition are made by hand, the supply can be guaranteed - of course, the special combat team is mainly to carry out special tasks and raids, and the handguns are more suitable than the spears, and the rifling of their handcuffs can easily exceed the range of ordinary smoothbore guns."

"That's it." "The Guards battalion and the future Marine Corps are armed with Minny guns, and the Special Combat Corps uses the handcuff version." ”

Lin Weiye was still unsatisfied: "I have to ask Father George to continue to help, get an original version of the gun with a scope, so that you can play sniper at a distance of several hundred meters, I am excited to think about it!" ”

Xia Nan's eyes lit up and praised: "This can be had." If two armies face each other, what a hilarious thing would it be to destroy the leader of the other party with one shot? ”

Lin Weiye continued to expand his brain: "Train a few reliable snipers and infiltrate the enemy city, you can carry out assassination, such as Huang Taiji and the like, as long as you leave the palace, you will have a chance to kill them!" ”

"Hahaha......" The two were immersed in lewdness, looking at each other and laughing.

After the acceptance of the new equipment was passed, the subsequent design, adjustment, and improvement will be handed over to Lin Weiye, and then Sun Yuanhua, who is in charge of military quartermasters, will follow up, arrange the production of the arsenal according to the required quantity, and finally deliver it to the relevant troops. There is a complete set of processes for military production, Xia Nan does not need to do everything himself, he has more important things to do.

Everyone was summoned to the South Park for a meeting, and the staff was the most neat in nearly two years.

Xia Nan first defined the meeting: "In the future, as long as there is no war, such a conference will be held regularly." The territory under our control is getting wider and wider, the number of military and civilians is increasing, and things are becoming more and more complicated, and it is no longer possible to effectively manage by relying on the simple model of single person in charge, and we need to work together and cooperate with each other and various management and agencies. ”

Sima De and Sun Yuanhua thought to themselves, this kind of meeting mode is almost the same as the court meeting of the imperial court, it seems that the general is preparing for a rainy day in order to become a great treasure in the future.
