The sandbar weapons test site, the desolate beach that had been before the people came to this was already a fairly large clearing, and although the ground was still sandy, it was all surrounded by walls. Pen %Fun %Pavilion www.biquge.info please search and see the most complete! The fastest updated novel has a watchtower every fifty meters inside the tall walls, guarded by Army and Marine Corps soldiers who are tasked with warning overly curious natives to avoid letting them approach the weapons testing site.

If you want to talk about the most mysterious place in the entire Senate, it is definitely this area, whether it is the rifles, artillery or grenades that the army is equipped with, they can only be installed after sufficient tests here. Often, a mounted weapon needs to be tested more than 20 times in this test site, and then the veterans of the armament department will lead people to examine and accept it, so that it can be included in the installation plan, and the production of weapons after installation is not an easy matter. You must know that the production of weapon parts in this time and space is quite irritating, with large tolerances, low quality, and low speed, and these problems have always plagued the weapons development and production departments.

"It's a pleasure for everyone to come to the Sandbank Weapons Test Site, welcome!" Lin Shenhe stood in front of the weapon display table and nodded to the veterans who came to watch the weapon test, "This is a weapon we have developed recently, please take a look at this bolt-action rifle first." ”

"Bolt-action rifles?" An elder muttered on the side, "Bolt-activated rifle, the rate of fire is still too slow, right?" ”

"How can it be slow?" Lin Shenhe said a little unhappily, "This is modeled after the Mauser 1898 bolt-action rifle, which can be loaded with ten rounds......

The enemy of the ship hated the war, and the early section sailed

The enemy of the ship hated the enemy, and the war was troublesome, and the early branch sail "Bang!" He felt a heavy push on his shoulder, and the butt of the gun hurt his shoulder, and the cheeks that were attached to the butt of the gun when aiming were numb from the recoil, and his eyes were full of gold stars.

"Ten bullets?" Another veteran interrupted Lin Shenhe curiously, "Isn't Mauser from a five-round magazine?" How can I get to you to fit ten rounds? ”

"Hehe, look here!" Lin Shenhe pointed to the rifle magazine with a satisfied look on his face, "We have modified this position of the rifle, and it has been changed to a magazine of ten rounds. ”

Sun Qiuyuanke alone checked and made trouble

"It's pretty much the same, the Germans all did five rounds at that time, and they were often pressed by Ying Qiqi's ten-round magazine when they started fighting." Liu Lihua immediately found a happy place, this guy who rushed to the beach with a swastika on the day of landing has always dreamed that he can have a 98k, and today he finally has the opportunity to see an imitation 98k, and it is a ten-round magazine, and he can't help but chatter there excitedly, "Mauser's five-round magazine has always been very annoying, the Germans used to carry out magazine modification kits on rifles during World War I, which can modify the Mauser rifle to a magazine capacity of about 20 rounds." ”

Lin Shenhe nodded, "That's right, we also know very well that five bullets are not fought at all on the battlefield, and loading and time-consuming, so our new gun was designed with a ten-round magazine at the beginning." As he said and picked up the rifle, Liu Lihua keenly caught the difference in the rifle, "What is the caliber?" Not 12 mm anymore? ”

"Hey, hey!" Lin Shenhe pointed at Liu Lihua quite excitedly, "BN! That's right, in the last equipment discussion, we got feedback from the troops about 12mm rifles, and they were quite dissatisfied with the performance of oversized ammunition. ”

"Yes," a veteran chimed in, "the 12mm lead-headed warhead is too heavy, there is too much propellant, and when it is fired, it is full of smoke, and basically if you fire a salvo at most twice, you will be obscured by the smoke of gunpowder, and you can only shoot forward in rotation when there is no wind, otherwise you will not be able to see the opposite situation at all." Moreover, the recoil of this 12 mm caliber ammunition is too large, and it is easy to be hit by the butt when firing and the shoulder hurts, and if the combat intensity is large, the shooting accuracy will decrease due to long-term firing. ”

"So based on that feedback, we redeveloped a new set of ammunition, the seven-millimeter armor lead bullet." Lin Shenhe said and picked up a bullet from the table, "Look, this is the new seven-millimeter bullet." ”

The patriarchs rushed up and flocked to the front to watch, this bullet was obviously one-third shorter than the previous thick twelve-millimeter bullet, and the volume was only three-fifths of the latter, but the bullet was not pointed. Several patriarchs curiously stepped forward to hold it in their hands, and were waiting to observe it carefully, when suddenly someone exclaimed, "I'll go!" This is a hexagonal bullet? ”

This exclamation immediately attracted more elders to rush to the bullet and pick up the bullet to watch, and sure enough, the cross-section of the bullet was really hexagonal. "How is it hexagonal?"

"This is a verification bullet," Lin Shenhe said with a smile, "We have produced two different bullets, this hexagonal bullet is used with an inner diameter hexagonal barrel, this bullet can be made with a steel case or a direct lead head, the advantage is that the bullet tolerance is a little larger will not have much impact, the disadvantage is that the recoil is too large, only one-fifth lower than the 12mm rifle bullet." ”

Sun Didi's hatred Sun Qiu took the cold ship post test

"So what are you doing with this? Kill it directly and can't end it? An elder said unconcernedly. Lin Shenhe shook his head and said, "This is not easy, although our bullets have a production line to produce, the tolerance is not large, but the production of the barrel is different, often the tolerance of the barrel drilled out is relatively large, if the rifled barrel is used, the scrap rate can almost reach about fifty percent, which is very bad news for the troops who urgently need to be reequipped." ”

"Of course," Xue Ziliang said with a smile on the side, "It will double the cost of the barrel for no reason, and it can't be done." Wu Di also nodded on the side, "I don't want to change me." ”

"That's right!" Lin Shenhe gave a thumbs up to the two of them and continued, "We still have one more problem, rifled weapon bullets are good, but the main thing we use to make warheads now is lead. Lead is a soft metal that melts when fired. Fragments of lead in the barrel of the gun will swirl out as the bullet flies out of the muzzle, injuring people nearby, commonly known as hanging lead. In addition, melted lead remains in the barrel, and the rifling is gradually filled, which is quite troublesome to clean up, and I think everyone should be familiar with this matter. ”

In front of him, a group of veterans of the military department all nodded in agreement, knowing that since the Senate rifle, the problem of hanging lead has always existed. And the cleaning of weapons is basically every three to five rounds must be carried out, otherwise the rifling will be directly filled, resulting in uncontrollable ballistics, serious decline in the accuracy of the weapon, and even causing danger such as exploding.

"For this problem, we have also thought of a way to deal with it, at the beginning it was a trial production of iron-shelled lead-bearing warheads, but even if it is an iron shell, it will still be scraped off a lot of debris by rifling, although the frequency of needing to clean the barrel and chamber has been reduced a lot, but the frequency is still too high, which will directly affect the battle. This problem is especially evident in heavy machine guns, where the barrel must be cleaned immediately after firing 200 rounds, otherwise the lead dust left inside will directly affect the life of the machine gun. Lin Shenhe picked up a bullet from the table and continued, "The second method is to use a steel-shelled lead bullet, but everyone knows that the steel-shelled bullet is very hard, and our barrel is also made of steel. ”

"Can't we chrome?" Xue Zi asked curiously, "We have this technology." ”

"That's right," Lin Shenhe nodded, "We have this technology, but the problem is that we don't have chromium!" He said and pointed to the north, causing all the elders to stretch their necks to look north, "We have iron ore, but the main ones are pyrite rather than chromite, and chromium is easy to produce hexavalent chromium when it is produced, this thing can invade the human body through the digestive tract, respiratory tract and even skin and mucus, causing chronic damage to the human body, and the toxicity is not low, it is one of the products that the Senate prohibits from being produced within two hundred kilometers of the Oriental Port." If we could have produced it, we would have been chrome-plated a long time ago. Lin Shenhe said and chirped his mouth twice, making the elders wonder what this action represented.

"In contrast, although the production of hexagonal bullets and hexagonal barrels is a little cumbersome, it has a lot of advantages in the wear and tear of the barrel, we can use it directly without chrome plating, and we have tested it, such a hexagonal rifle can shoot 1oa accuracy at 600 meters, and it is also a random rifle, not a special sniper bullet." As soon as Lin Shenhe's voice fell, someone squeezed him, "We don't have special sniper bullets." ”

"Hehe," the elders in front of him laughed heartlessly. Lin Shenhe also smiled, and then picked up the hexagonal rifle that imitated 98k, pressed a ten-round bridge clip into the magazine, and then pushed the bullet into the load, "Who will try it?" ”

He Rolling Dragon was the first to come up, "I'll try?" Immediately, someone below shouted, "What are you doing with the air force?" All you have to do is fly the plane. He Rolling Long looked depressed, but Lin Shenhe stuffed the rifle into his hand without saying a word, and pointed at a humanoid target two hundred meters away, "Let's try it with a shot." ”

He Rolling Dragon nodded, walked to the firing position, unfastened the rifle safe, took a few deep breaths, then flattened the rifle and began to aim in the distance. The new rifle feels much lighter than the 1628-1629 rifle, and it uses a bore sight. It seems that the rifles of the Senate's military-industrial department basically used a bore sight, which naturally focused on the target by using human physiology. He took a deep breath and pressed the front sight against the red area of the distant humanoid target, then exhaled the air in his lungs and pulled the trigger.

"Bang!" He felt a heavy push on his shoulder, and the butt of the gun hurt his shoulder, and the cheeks that were attached to the butt of the gun when aiming were numb from the recoil, and his eyes were full of Venus.

The patriarchs in the back raised their binoculars to look at the target, and after a long while, one of the patriarchs asked softly, "Where did you go?" ”

"That's it, I didn't see it either," "In the end, it's from the Air Force, it's a plane, haha......" He Rolling Long's face was a little uncomfortable, and he just wanted to speak, but Lin Shenhe took the rifle over. Lin Shenhe looked down for a while, and hurriedly said loudly, "I got it wrong, this is a brand new gun that has not been shot at the school," he said, picked up another rifle from the table and handed it to He Rolling Long, "With this one, this one has already fired more than thirty rounds, no problem." ”

After the hatred and hatred, the moon ghost Taixing of the school

He Rolling Long nodded silently, took the rifle, and checked the chamber and magazine, which were empty. Lin Shenhe hurriedly handed over another bullet, "I'm sorry, just reload it manually, I won't give you the bridge clip." He Rolling Long continued to nod and stuffed the bullet directly into it, "Bang!" The recoil gave him a strong sense of impact again, but because he had learned from aiming, he didn't put his cheek raiser on the butt again, and it was just a little painful in his shoulder.

"Hit, it's pretty good, that shot just now was really a problem with the gun." Liu Lihua was the first to shout.

The enemy is not the enemy, the ship is cold, the star is cold, and the star is not

"How expensive is this gun to make? Compared to the 1628 rifle. Wu Di asked curiously, "Is it higher or lower?" ”

"Of course it's higher," Lin Shenhe sighed and said, "This is no way, compared with the old-fashioned rifle, the parts used in this rifle are obviously a lot more, and the amount of work when drilling the barrel is much larger than that of ordinary rifling, so the cost is about one and a half times that of the 1628 rifle." ”

"The price is too high, we can't equip it." Wu Di shook his head, "You see, we were equipped with a Senate rifle at the beginning, and after two or three months of use, we replaced it with a 1628 rifle, and before it was warmed, we improved it into a 1629 rifle with a kit, and we were also equipped with a carbine that used 9mm pistol cartridges, and we were also equipped with a 1628 revolver. Now, you have come up with this new rifle, can you not be so diligent in equipment replacement? What about the revolution of saving and saving? Before the year passed, Hula Hula had changed three generations of weapons. Our Senate has money, and if you have money, you can't toss it like this. ”

"That's it," one of the patriarchs next to him began to speak loudly in agreement. "Can't your weapons design department just go one step and directly produce better weapons? We are armed with this hexagonal rifle now, and who knows how long it will take to make a better one? At that time, change your outfit again? ”

"That's right," Li Jieqi spoke, "the speed of our weapon replacement can be said to be unacceptably fast, this year's national defense budget is not much, and even less can be left on equipment upgrading, if we continue to improve like this, I am afraid we really can't keep up with your replacement speed." ”

"I said Lin Shenhe," Wu Di saw that Lin Shenhe's face was a little unbearable, and hurriedly defended, "I'm not saying that you are not good at developing new weapons, but you should be cautious in the selection of models at the beginning, the army's weapons and equipment are different from the development of personal hobbies, and soldiers often need a lot of time to become familiar with a weapon." The speed of changing equipment is too fast, and it is also a trouble to familiarize yourself with the weapons of the troops. I said that the 1628 rifle could not be modified? For example, an upgrade kit or something. ”

(Suddenly I want to try, try next month to see if I can 8k words a day, it would be great if I could, haha, everyone support me more, thank you!) ）
