The 6.5*42mm intermediate power bullet because of the use of 6.5*50mm full-power warhead and cartridge case, so there is no problem in the production and processing, and even due to the reduction of cartridge case materials and charges, the production efficiency has been improved a lot, more importantly, this ammunition can be produced on the basis of the existing gun and ammunition production line, and the adjustment of molds, machine tools, and punches is minimal.

As for the performance, in addition to the range is not as good as the original 6.5*50mm full-power elasticity, the others are basically the same, and in terms of lethality, due to the use of the boat-shaped tail design proposed by Bai Yi, this new 6.5mm intermediate power bullet is more frustrating in terms of lethality.

You must know that the 6.5*50mm full-power bullet will cause fatal cavity damage to the human body at close range because of the large length-diameter ratio, and what is lacking is long-distance lethality, and after the use of the boat-shaped tail design, the final defect of the 6.5mm ammunition in terms of lethality will be completely compensated.

Because relying on this design, the 6.5mm ammunition not only has a longer range, but also greatly increases the probability of rolling after entering the human tissue, so it can be said that as long as the 6.5mm ammunition hits the torso within 400 meters, unless a miracle occurs, there is almost no possibility of survival, because the cavity effect produced by the violent roll can directly twist the internal organs.

Take a few sick cows used for the lethality test of guns and bullets a few days ago, after a shot, the arteries of the cattle were cut, the lungs were strangled to bloody flesh and blood, and one-third of the heart was completely ruptured.

For the 6.5*42mm intermediate power bullet, everyone present knows very well, and it is needless to say that what they are concerned about is the new design in Bai Yi's plan, two wedge-shaped iron blocks, with a pair of cut hooks together, to form an opening and closing lock motion assembly.

There is an oblique groove at the bottom of the receiver, the front section is a small protrusion, when the bolt moves here, it will be offset under the action of the protrusion, so as to complete a series of actions such as seat, throwing the shell, etc., it can be said that the whole structure is simple, and effective, and more importantly, the casing that can be separated is obviously not cut with a piece of metal, and it is obvious that it can be processed in a more time-saving and labor-saving way.

"This structure...... I think I've seen it somewhere, right...... That's right...... Lao Maozi's SVT-40 semi-automatic rifle is very similar to this gun structure, but it seems to be a little different! ”

Just when everyone was discussing Bai Yi's plan, Wang Dehua suddenly screamed out silently, and then raised his head and looked stunned, as if he had thought of something.

A big hand slapped his head violently, and with a crisp sound of "pop", he shouted as if he had just woken up from a big dream: "My brain, when the old Maozi swept through the Kwantung Army, I had seen the SVT-40 semi-automatic rifle, and I had also done basic repairs for them. ”

After speaking, he turned his head to look at Bai Yi again, stretched out his thumb and gave Bai Yi a thumbs up: "This should be the improved version of the bolt used in the SVT-40 semi-automatic rifle, if our automatic rifle uses this structure, then my old Wang not only has no opinion, but also sincerely admires Bai Section Chief, you can use it so exquisitely, which shows that you have a deep understanding of firearms in various countries, it is unimaginable!" ”

Wang Dehua's sudden move not only startled Bai Yi, but even the people around him were shocked, and said what was going on, Wang Dehua, who was not very good at saying flattering words, actually praised Bai Yi in front of everyone, and his admiration was not a lie at all, but the question was why this was so, and what was the SVT-40 semi-automatic rifle he was talking about?

Wang Dehua, who was aware of the doubts around him, finally realized it, and hurriedly explained that when the Soviet army sent troops to the northeast, Wang Dehua was fortunate to come into contact with the SVT-40 semi-automatic rifle, and not only that, but he was also approached by the technical cadres of the Soviet army at that time to assist them in maintaining this gun.

Therefore, he was very familiar with the various structures of the SVT-40 semi-automatic rifle, but later because the Soviet army removed the machinery and equipment of the Baiyun Factory, Wang Dehua was very dissatisfied with the Soviets, and the ensuing civil war made him once again in duckweed-like turmoil, and the SVT-40 semi-automatic rifle that left a deep impression on him also slowly disappeared in this dissatisfaction and turmoil.

It wasn't until today that he saw the familiar frame again, the two closed bolt components, that Chen Jiu's memory was awakened again, but it was precisely because of this that he was both annoyed and shocked, and his chagrin was naturally why he didn't think of this, as for the shock, of course, Bai Yi's familiarity with firearms and his ease of use of various structures.

You must know that in the world at present, the rifle that adopts this structure is only the SVT-40 semi-automatic rifle of the Soviet Union, and most of the semi-automatic firearms and fully automatic firearms still use the bolt rotary locking mechanism, even if it is the Soviet Union of origin, the SVT-40 semi-automatic rifle is not a standard rifle commonly equipped, but a niche firearm used by reconnaissance troops.

Even many Soviet soldiers are not familiar with this gun, let alone understand it, and Bai Yi is not only familiar with it, but also has a deep understanding of this firearm, although Wang Dehua also knows that Bai Yi once studied in the Soviet Union and later participated in the war against Germany, but this does not mean that Bai Yi knows all the Soviet weapons and equipment.

But now, a few chapters of rough sketches not only show that Bai Yi understands, but also shows that he has done in-depth research on these firearms, otherwise, it would never be possible to adopt such a bold and avant-garde design idea, let alone further simplify its original simple structure.

After listening to Wang Dehua's explanation, everyone looked at Bai Yi like Wang Dehua, almost full of little stars, jokes, a person who can study Soviet firearms so thoroughly is completely worthy of their heartfelt admiration, not to mention how old Bai Yi is? But in his early twenties,

But he was able to completely understand the things of the Soviets, not to mention, and even had his own unique opinions, how much effort did it take to obtain? It was not said that everyone in the audience bowed to Bai Yi, but also raised his technical status by several levels in their hearts.

However, Bai Yi was extremely uncomfortable with the eager eyes around him like chasing stars, and finally could only lament helplessly in his heart, don't underestimate this era, maybe the uncle sitting in front of you is a powerful man, and if you are not careful, the old foundation may be exposed......
