Compared with firearms, bullets are more difficult to make, since the emergence of professional bullets, bullets relative to firearms, the difficulty has risen more than one level, in this world, there are many countries that can manufacture firearms, even the Qing court, can barely be said to be able to manufacture firearms, but bullets, basically the self-production rate is quite low, most of them, are reloading bullets, and there are very few countries that can really produce bullets.

Even with the improvement of bullets, more and more professional, more and more widely used, the production of bullets in the geometric shape of the increase, in the 21st century, some countries, can even manufacture warships, send satellites to the sky, but do not have the ability to produce bullets, bullets have also become a huge threshold representing the country's military potential.

Professional bullets, most of them are made of copper shells, China lacks copper, from the feudal society to the end of the Qing Dynasty, copper has always been an important material, because copper money is the main transaction currency, and therefore, the emergence of copper panic, so that China's strength has not been able to completely burst out, Jiaozi, iron money, the emergence of flying tickets, is also a historical necessity, as for gold and silver coins, that is, in the Ming Dynasty and Qing Dynasty, it slowly flowed into the country, becoming the market, the more mainstream currency.

Bullets, from the day of birth, have been gradually improved, forming a relatively stable method, copper shell bullet is the basic configuration, on the one hand, copper flexibility is good, the ability to resist pressure is also strong, on the other hand, steel bullets are easy to rust, not easy to preserve, copper shell is much better, it can be said that steel shell bullets, there are many limitations, such as in terms of maintenance, in low temperature, and even in hot and humid climate, the middle copper shell bullet does not have such a problem.

China does not have a lot of copper mines, copper is a precious metal, the future generations are like this, had to choose a steel shell or iron shell bullet, Yang Yuanzhao of course knows what to choose better, at present the entire Chinese copper mine is quite limited, but Mongolia side, there is an untapped gold and copper mine, itself, Yang Yuanzhao does not intend to develop him, but the trouble of guns, let him take time to pass, test the approximate reserves and layout, open up a mine with about 1.2 million tons of reserves, ore grade high, And with the help of a large number of machinery and equipment purchased from abroad, the mining of copper ore began.

1.2 million tons of copper, may not be able to expand comprehensively, but for the Baotou arms industry, it can be counted as enough, at least can support a few years, and even because of the discovery of this extra-large copper mine, so that Baotou is suppressed, copper in the eyes of anyone, is money, a 1.2 million tons of copper ore, equivalent to hundreds of millions of catties in the city, if made into copper coins, is an extremely huge, unimaginable number.

The bullet is never simple, a small bullet, contains a lot of technical content, divided into a lot of parts, no matter what style and shape of the bullet, it is composed of four parts: the projectile, the cartridge (cartridge case), the firing yao and the fire cap (primer). For bullets, no matter what they are used for, most of the general-purpose firing yao are non-yan-fire: non-yan-fire-yao can be divided into (single-base, double-base, three-base) (its main component is nitrate cotton), and firearms are mostly single-base drugs. There are different requirements for different firearms and ammunition. Pistols mostly use porous and quick-ignition single-base drugs. The rifle uses a lightened and passivated single-hole granular single-base agent for the surface.

The primer is composed of a fire hole, an anvil and a firing agent. Its function is to produce a flame when it is fired, and it ignites quickly and surely. When firing, the firing agent is ignited by the impact of the firing needle and the fire anvil, and the flame is ignited through the fire hole. When fired, the firing pin excites the fire cap (primer). The primer burns rapidly and ignites the firing yao in the cartridge (cartridge case), and the firing yao produces instantaneous ignition, and at the same time produces high temperature and high pressure to extrude the projectile (warhead) from the cartridge, and the projectile at this time moves forward under the impetus of the high pressure generated by the firing yao, and is squeezed by the rifling, resulting in rotation, and finally pushed out of the chamber.

In this era, the importance of bullets has not been clearly understood, and even the threshold of bullets is not high enough, and there is no development of bullet categories like later generations, perfect categories of bullets, but the production line still has to be self-made, there is no arms dealer or arms processing factory, the brain-dead bullet production line is exported, no matter how rich it is.

Fortunately, from the Czech Republic, Slovakia, Norway and other countries, as well as the arms experts from Italy before, most of these people are military factories, and even directly from the bullet factory, Yang Yuanzhao reasonably integrated them together, so that they put forward the idea, under the strong industrial processing capacity and integration ability of Baotou, and finally under the collective efforts, a small production line with a daily production capacity of 50,000 rounds was formed.

Baotou has the ability to produce munitions, especially the most basic is nitric acid, because the completion of the method of synthesizing ammonia to nitric acid, along with the gradual expansion of the nitric acid factory in Baotou, the current daily output of nitric acid has been an astonishing 8,000 tons, and the annual output is close to 2 million tons, according to the ratio of 1:10 or even higher, it can produce enough such output, which can definitely support the production of any munitions.

Nihua cotton, single base, double base, three base, such a category of nitrate cotton, as long as there is enough quantity, enough real yàn times, can always be produced, those military experts, although there is no direct manufacturing line ability, but can be based on the existing things, the production line is instructed, help Baotou improve the production line, now the daily production capacity of 50,000 rounds of small production line, is on the basis of 3000 rounds, gradually modified over, now, is studying 100,000, even 300,000 production lines, Basically, by 300,000 rounds, the basic shape can be finalized, and then on the basis of this, continuous copying, the construction of a modern bullet factory can be completed.

The automation process of this production line is not high, the production line of 50,000 rounds, a total of 217 people were used, in Yang Yuanzhao's thoughts, it is best to reduce the number of people to about 50 people, which requires the gradual improvement of the production line, the production of munitions, especially bullets and explosives, the danger is quite high, speed is not the only indicator, safety performance, is the strongest indicator.

The standard caliber of AK is 7.62 caliber, in this era, the caliber of most of the firearms is very large, the caliber of Mauser 1898 is about 7.92, the caliber of most of the guns is even above him, the inherent production line, the bullets produced, most of them are large-caliber, Yang Yuanzhao seems to have read an article, specifically mentioning the difference between Asia and Europe, in this era, Europeans are a little stronger than Asians in terms of height and strength.

This is Yang Yuanzhao's personal experience, whether it is height, or weight, there is a big gap between China and foreigners, this is not one or two particularly strong can be solved, the army, especially in this era, the army, from a certain Cheng dù above, considers a whole above, su zhì above, is based on the average su zhì of the people, especially men, that is, at present, the caliber of about 8MM suitable for foreigners is not very suitable for Chinese, smaller caliber, It is conducive to the use of Chinese.

Later generations famous, the notorious 38 rifle, it is 6.5MM caliber, such a caliber rifle, has good performance, but also suitable for Asians, especially East Asians, became Japan in World War II, the main rifle, but, such a 6.5 caliber rifle, is not without shortcomings, due to the small caliber, the stopping force is not strong, most of the time, will produce a penetrating effect, and can not be used better.

Synthesizing some arguments, Yang Yuanzhao chose a 7.0 caliber for the new assault rifle, which is neither like 7.62 and 7.92, which is heavier and not conducive to Asian use, nor like 6.5, which has a weak stopping force and is easy to produce a penetrating effect, and the effect is not strong.

Nowadays, such a production line is to produce 7.0 caliber rifles, shiny brass cartridge shells, under the strict work of workers and production lines, it has become an assembled finished product, after testing, Yang Yuanzhao picked up one, he can't tell what kind of power such a bullet has, but it looks good.

"Do you want to shoot a shot?" Liu Shujian said. As a person less than 30 years old, Liu Shu still likes firearms, this new gun, as soon as it looks, is very good, how can you do it if you don't try it.

"Then try it!" Yang Yuanzhao is indispensable, by the way, he said: "Call Brother Huanzhang too, and let him see by the way, what is the specific effect of this thing!" ”

At present, Baotou has preliminarily installed telephones, is purchased from the British telephone lines and computer rooms, the initial installation of most of the key places in Baotou, Baotou finally ended the era of using to go, with shouting, after all, this is not the border town before, but a very modern city, in this city, even if it is around the city, it also takes dozens of kilometers, and then rely on the previous method, the efficiency is quite low.

Maybe sometimes, it will delay the work, so under the establishment of some scientists and factory leaders, a complete set of telephone equipment imported from the United Kingdom, successfully got to China, not a program-controlled telephone, need a switchboard to transfer, but it has been extremely convenient for everyone, at least, if you are looking for someone, dial the phone directly, do not need to let the long-term entourage or assistants, run a few miles to notify, once this initiative was launched, it was immediately recognized by most people, and even now, there are some civilian voices, asked for universal telephone, but Yang Yuanzhao did not agree.

In this era, the installed capacity of the computer room telephone is quite low, and if you want to solve it, you need to wait for the future program-controlled phone to come out.

Liu Shu went to make a phone call, Yang Yuanzhao continued to visit the entire bullet factory, he did not have a special understanding of military production, so he did not rashly insert opinions, just wrote down what he saw, and by the way, instructed the person in charge to prepare a shooting range and some guns and ammunition.
