Song Zhewu already had a fixed opinion in his mind about the choice of the caliber of his standard rifle in the future, and he wanted to choose the 6.5mm caliber, after all, the small caliber is the trend of future development.

Moreover, for the strong penetration of the 6.5mm caliber rifle, it may seem to others to be a very serious problem, but in his mind, this is not a problem, he has already had a solution.

However, in order to avoid his too "unbelievable" remarks and once again causing the shock of experts, Song Zhewu is now more willing to listen to other people's advice first.

Xiao Guodong said: "Wen Ge, this is Zhou Weifeng, the director of the rifle factory, who was the technical authority of the rifle factory during the Yan Xishan period. ”

Although Zhou Weifeng had often seen Yan Xishan before, and he was also a person who had seen big scenes, but in front of Song Zhewu, the new boss who is now legendary, Zhou Weifeng still seemed somewhat at a loss.

Seeing that Zhou Weifeng was a little nervous, Song Zhewu smiled and said, "Very good!" On behalf of the Fourth Route Army, I once again welcome Director Zhou and all the experts from the former Taiyuan Arsenal to join the Fourth Route Army. Just one thing you have to remember is that since the day you joined the Fourth Route Army, we have been a family, don't worry, just say what good advice you have. ”

Song Zhewu's amiable words made his heart feel a lot more steady, Zhou Weifeng calmed down, sorted out his thoughts and said: "Now Taiyuan Ordnance Industry ......"

"Oh! It is our northern machinery and equipment company, and now the firearms produced are mainly imitation type, and the caliber is basically 6.5mm. Therefore, the equipment, including the ammunition production line, is also equipped with this, so I think that the caliber of our rifle should still be 6.5mm. ”

"As for the problem of excessive penetration of 6.5mm bullets, there are no more than two solutions: one is to increase the entanglement distance of the rifle's double line. It's just that this comes at the expense of the exact surname; It's about making a fuss about bullets......"

Sun Sihua asked a little puzzled: "Director Zhou, I don't think it's enough to sacrifice an accurate surname, there is still a way to use bullets?" There's a way, why didn't you say it earlier? ”

Zhou Weifeng's face was a little red, he felt that he was a little speechless, he could say it, it was impossible to take it back, looked at the few people around him who were from the Taiyuan Arsenal, opened his mouth in embarrassment, and finally sighed and did not speak.

Several other people from the Taiyuan Arsenal also looked away with strange expressions.

Xiao Guodong looked at everyone in confusion and asked Zhou Weifeng: "Director Zhou, what is going on?" Zhou Weifeng was a little remorseful for talking too much just now, but the matter has come to this point, and he will definitely not be able to say the reason.

"Chief of Staff, it's not that I don't want to say it, it's just that this matter is a little difficult to say."

Seeing Song Zhewu looking at him with encouraging eyes, Zhou Weifeng secretly gritted his teeth and said with a heart: "Commander, chief of staff, that's the case, not only foreign ammunition, but also bullet warheads produced by domestic arsenals such as Hanyang, Jinling, and Shenyang are all made of copper-nickel alloy. ”

"However, we lack copper in Shanxi, and most of the copper mines are still concentrated in Yuanqu, Wenxi, Jiangxian, Xiaxian, and Yuncheng in the Zhongtiao Mountains. Because they are all in the mountains, mining is difficult. In order to save money, we use earth copper smelted in earthen furnaces, which is nickel-free copper. Last year, we imitated the principle of the British 7.7mm empty tip bullet and created a 6.5mm tip bullet, the purpose of which is to save copper. ”

Since Zhou Weifeng began to speak, his mood gradually stabilized, and his words became more and more fluent.

"British 7.7mm air-tipped bullets, the inside of the bullet center is front aluminum and back lead, and some bullets are filled in the front of the warhead with paper pulp in order to reduce costs.

"The 6.5mm bullet we produced in imitation also uses this process, but the pulp is changed to ...... Shanxi straw paper. ”

Speaking of this, Song Zhewu noticed that Zhou Weifeng and these people from the original Shanxi Arsenal had become very embarrassed.

"Bai Gong often said, 'Zhang Zuolin is rich, 10 yuan is a dollar; Duan Qirui has no money, one yuan is used as two yuan; Meng is poorer than Lao Duan, so he has to spend one dollar as ten yuan'. The purpose of using air-tipped bullets was just to save money. ”

"I once thought that this kind of copper smelted in the earthen furnace, because it has not been refined, contains a large number of impurities, and after such a warhead hits the human body, due to the tumbling effect of the hollow-tip bullet, the warhead will be shattered almost instantly, and the straw paper filled with the front of the warhead will also spread to the wound with the shattering of the warhead. During the Great War in the Central Plains, there were many people who had their wounds deteriorated due to the large amount of bacteria and other substances carried on the straw paper......"

Shock, absolute shock! Not only Song Zhewu and Xiao Guodong, but also Zhou Liqun and Sun Sihua, as well as many people present were speechless in surprise!

After all, the Great War in the Central Plains is a Chinese of Chinese, and any side that is injured is Chinese bleeding, not to mention the death of the other party by such despicable means.

The vicious bullets that will explode in the human body and seriously infect the injured come from their Taiyuan Arsenal, which naturally makes the people of the former Taiyuan Arsenal keep their mouths shut and blush with shame when they say it.

"Dammy Bullet! In terms of effect alone, this is a real dummmm! ”

Song Zhewu not only secretly exclaimed in his heart. He had heard about this in his previous life, and he originally thought it was a lie, but he didn't expect it to be true!

"No, the sinister Yan Laoxi, this kind of bullet produced is even more evil than the dummy bullet that is expressly prohibited by international law! The bullet he produces is simply a biochemical dummy bullet! ”

The dummy bomb appeared in 1897 and was designed by Captain Clay, the British military director at the Dham Arsenal in India. The tip of the warhead did not cover but exposed the lead core, which expanded or ruptured when the bullet entered the human body, thus enlarging the wound surface and causing serious injury to personnel.

In the event of a direct hit by a dummy bullet at a distance of 100 meters: the wound is in the head - 100% of the person will die; In the limbs - 20% die, the rest are amputated; in the left chest (near the heart) - 100% death; right chest - 70% death; Abdomen - 70% die.

Because the lethal effect of dummy bullets is amazing and inhumane, the use of dummy bullets is now expressly prohibited by the Hague Convention!

If this kind of bullet produced by Yan Xishan is brought to the international market, it will be 100 percent included in the category of dummy bullets, because its lethality rate will not be smaller than that of dummy bullets, and it will even be more serious. The reason why the death toll in the Central Plains War reached hundreds of thousands may have a lot to do with this kind of bullet.

Moreover, Song Zhewu even thought in his heart, "After the victory at Pingxingguan, the commander of the 119th Division, Linb, was shot and wounded by the soldiers of the Jin Sui Army, that bullet is probably this kind of dirty bomb, otherwise how could he have deteriorated from his health, and later even reached the point of being afraid of water and light."

Although this kind of bullet is very vicious, and it is really harmful to use it on Chinese, but if this kind of bullet is used on foreigners, Song Zhewu does not mind. Especially when used on little devils, it couldn't be better.

However, these people in front of them obviously know that this kind of bullet is similar to the effect of a dummy bullet, and Zhou Weifeng and other people from the former Taiyuan Arsenal are reluctant to say it, which is the reason.

Even if Song Zhewu wanted to use this kind of bullet, Zhou Liqun, Sun Sihua and others would feel uncomfortable, not to mention that if this news spread, it would have a great impact on his reputation. You can't use it yourself.

Song Zhewu patted Zhou Weifeng on the shoulder and comforted everyone: "It is indeed very undesirable to produce this kind of bullet, because it is all Chinese." However, it's no wonder that you guys, whether to make this kind of bullet or not, only Yan Xishan has to say. ”

In fact, Song Zhewu knows very well that the reason why "The Hague International" only prohibits the use of dummy bombs is because people have not studied trauma ballistics deeply enough at this time.

In fact, any warhead that can release a huge amount of energy in a short period of time can cause a similar effect to a dummy bullet, even a normal all-armored warhead.

One of the most common cases is ricochet, that is, after the warhead of normal and stable flight collides with the surface of a hard object at a certain angle, it rebounds, changing the trajectory and stability of the warhead's flight. If this kind of warhead hits the human body again, because the warhead has been deformed after collision and becomes very unstable, it will generally hit the target with the side, and then the warhead will disintegrate and shatter, which is almost the same as the killing effect of the dummy bullet.

Even the 6.5×50 mm Arisaka rifle cartridge used by the Japanese army can achieve this effect under certain conditions.

Because the 38 rifle used a long pointed bullet, in order to keep its center of mass in a position a little back, the arc part of the bullet in front of the armor was made very thick, and the cylindrical part was thinner. Although the Type 38 rifle has a small winding distance and a high rotation speed of the bullet, it is relatively stable, but the nutation effect of the bullet is more obvious after it comes out of the muzzle, and it is very easy to lose stability and roll when hitting a living target at close range, causing the bullet to be seriously deformed or broken, and its lethality is similar to that of a dummy bullet.

However, after its nutation disappears and it enters the stable flight stage, the warhead is not easy to roll, the wound path caused is relatively straight, and the killing effect is also significantly reduced.

At the end of World War II, due to the shortage of materials, the quality of the Arisaka rifle cartridge produced by Yuben decreased significantly, and there were many defects, but after hitting the human body, it became more likely to break and roll, and the lethality was increased compared with the previous product.

This is also similar to the bullet produced by Yan Xishan, except that he did not add "medicine" to the bullet, and the bullet made by Yan Xishan in the later period is said to be not filled with straw paper, but horse dung. In this regard alone, it is obvious that he is not as insidious as Yan Xishan.

There are many methods circulating on the Internet in the past life about the means and methods of using this principle of warhead instability to kill and injure the enemy, but there are many methods that have high requirements for the warhead manufacturing process, and it is difficult to achieve Song Zhewu's current level of military manufacturing.

However, Song Zhewu also disdained to use Yan Xishan's method......
