Chen Xin rubbed his eyebrows and said firmly: "You must not use lead bullet to fight rabbits." Pen ~ Fun ~ Pavilion www.biquge.info"

After hearing Chen Xin's words, the person in charge of the ordnance factory was stunned for a moment, although he was not a professional weapon designer, he still knew a lot about this knowledge.

He grabbed the technician who was about to refute, shut him up with a fierce look, and then took two steps forward and respectfully explained to Chen Xin, "Well, your lordship, the ammunition used by the rifled gun must be slightly larger than the caliber of the barrel in order to embed the warhead in the rifling and achieve the purpose of making the warhead rotate steadily."

Because the lead bullet is soft, as long as a pit is made at the bottom and a small wooden stick is installed, under the action of gunpowder, the lead bullet expands and deforms, embeds in the rifling, and achieves the purpose of rotation. So it can be made a little smaller than the muzzle, so that it can be loaded smoothly from the front of the barrel.

However, the hardness of other metals is not up to this standard, and if there is no way to expand suddenly, the warhead must be made a little larger than the caliber of the barrel in advance, so that it cannot be loaded from the front, which will block the barrel.

If you want to use other materials, you can only use the rear loadout.

Moreover, for that reason, cheap metal is too worn out on the barrel, and if you can't shoot a few shots, you may smooth out the rifling.

If the metal material with less rifling wear is used as a warhead, the price is too expensive.

The most suitable thing to act as a warhead is copper, and there are several alloys, the cheapest of which should be considered copper.

And a copper bullet is several copper coins. How much does a hare cost?

If the people don't think it's worth it, the rifle won't be sold.

Although rabbits are delicious, living within their means is already a deep-rooted consumption concept of the people, and they cannot spend more money than they can afford to buy a rifle that they can't use.

Moreover, without a rifle, you can also fight rabbits, but it is a little more troublesome and less efficient.

Your Excellency, your subordinates take the liberty of asking, why does this civilian rifle used to fight rabbits have to use ammunition of other materials? ”

Chen Xin helplessly spread his hands, "Because these rabbits are for everyone to eat, and lead, but it is a heavy pollutant, it is toxic." ”

“・・・・・・”

The person in charge of the ordnance factory was speechless for a long time, and finally said cautiously, "Your Excellency, as long as you dig up the place where the hare was hit by lead bullets, isn't it okay?" ”

Chen Xin shook his head, "It's not that simple, lead bullet is a soft metal, and when it hits the target, it will break into a large number of fine particles."

There is also a part that will quickly flow along the blood throughout the hare's body. Its levels are sufficient to cause mild heavy metal poisoning. If you eat this meat for a long time, the problem will get worse.

Military rifles are aimed at the enemy and don't care about that, but civilian rifles can't care less.

You must know that this is a matter related to the safety of the lives of our people, and we must not be careless. ”

Chen Xin looked at the two people in front of him and kept opening and closing their mouths, but they just couldn't make a sound, and they were helpless in their hearts.

He knew that the ordnance factory must have put a lot of effort into this civilian rifle plan, and now he vetoed the use of lead bullet in civilian rifles, which is tantamount to cutting off the sales of civilian rifles, but in this matter, Chen Xin will never compromise.

"But your lordship, if you want to ensure a certain number of shots while protecting the rifling, you can only use precious metals, which is contrary to the cheap strategy of civilian rifles."

"The kingdom's steel production is already very high now, what if steel warheads are used?"

"Your Excellency, steel is a very hard metal, and the ductility of steel warheads is very poor, and the wear and tear of rifling is also very large.

If a steel bullet is used, the service life of the rifle cannot be guaranteed, which was conclusive when the rifled military rifle was first demonstrated. ”

Chen Xin said with some open minds: "The service life required by military rifles is not the same as the service life required by civilian rifles.

After the people get the civilian rifles, they can't go to hunt rabbits every day, right? Aren't they going to work?

In this way, even if the life of the barrel is limited, as long as it can hold out for hundreds of rounds, it seems to be okay? ”

"What the king said is, but with a steel warhead, it is necessary to use a breech-loading rifle.

However, the kingdom's more mature aftermarket technology now only has the kind of bolt-on structure of the casing.

Jun Shang also knows that the price of that thing is too high, and because of the processing accuracy problem, it will loosen and leak after dozens of rounds are launched. ”

At this moment, things went around to the price again, Chen Xin was helpless, and the atmosphere fell silent again.

After a while, just as Chen Xin was about to send the two out of the house, the young technician spoke again.

"Your Majesty, I heard that the four-year rifle used by the army is ready to completely replace the military standard rifle because of the problem of loose bolt after long-term firing?"

Chen Xin looked at the other party, "That's right, didn't this task be issued to your ordnance factory a long time ago?" Why, you don't know? ”

The person in charge hurriedly explained, "Your Excellency forgives the sin, because there are already three veteran designers designing new military rifles, so these young people have not been arranged to work in this area." ”

Chen Xin knew it, and he was senior, although he didn't like it in his heart, but he didn't lose his temper with this old man who did his best for the ordnance factory.

It seems that the various oversight bodies will also be set up as soon as possible.

However, now is not the time to pay attention to those annoying things, Chen Xin asked the young technician, "What, what new ideas do you have personally?" ”

"Yes, your lordship, I have also designed a way to install it after that.

It's just that recently I've been busy designing this cheapest civilian rifle, so I haven't been able to make a finished product, and I can't show it to you.

However, I think that the after-loading mechanical mechanism I designed is very easy to process, and it should be very economical in terms of processing difficulty.

If, when the military is willing to use the rear-loading mechanical structure I designed, it will be a huge purchase.

In order to complete the army's orders as soon as possible, the ordnance factory will also set up a special production line for the division of labor and cooperation to specialize in the production of such casings.

At that time, the cost of such a receiver product will be reduced all at once.

If, on civilian rifles, we use the same receiver and increase the number of orders, then the price will definitely be lower.

As a result, the price of a rear-loading rifled civilian rifle that is finalized may not be much more than that of a front-loading rifle.

In addition, you don't have to worry too much about the service life, and the direct use of steel bullets is completely in line with the order that the king is not allowed to use lead bullet on civilian rifles, and the consideration of reducing the cost made by the ordnance factory.

Can you give this new civilian rifle scheme a try? ”
