After finding a welder to seal the steel pipe, Wang Qi went to the hardware store to buy lead bullets. He remembers seeing this kind of thing sold in the hardware store in his hometown when he was a child.

However, he went to several hardware stores in a row, but he couldn't buy lead bullets for air guns. The boss told him that there were fewer people playing air guns now, and the police station was still arrested, so he asked him to try his luck on a street in Jiangbei that used to sell I-brand air guns, and if he was lucky, he might be able to buy them.

Wang Qi couldn't help but feel disappointed. With a gun without bullets, an air gun in your hand is no better than a burning stick.

Just when he was about to take the car to Jiangbei to try his luck, Wang Qi's face suddenly changed, and he became very embarrassed, completely crying and mourning.

"Holy shit! I still think airsoft is a little too simple. Even if you can buy lead bullet now, you can't use the barrel you make yourself-Nima, the inner diameter of the barrel is 22 mm, and the lead bullet is generally only 4 or 5 mm, the size does not match, and the toothpick stirs the vat, and the air leaks!" Thinking that 90% of the cube has been completed, only the six barrels of the front sight and the door, Wang Qi felt a little like crying.

Moreover, Wang Qi quickly thought of another problem, even if there was a lead bullet that perfectly matched his current barrel for sale, he would not be able to use it. He had read in a document on European arquebuses that in the 16th century, the inner diameter of the Spanish Mushquet arquebus was about the same size as his current stainless steel pipe, 23 mm.

But how much does the projectile of such a musket weigh? 50 grams, one or two!

The charge is even more terrifying, divided into several grades according to need, ranging from more than 40 grams to more than 70 grams!

So, the power of this large-caliber arquebus is also quite terrifying, and it can shoot a large horse (if it can hit) from a distance of four hundred meters!

Because it was too heavy, nearly twenty pounds, the Mushkert arquebus could not be held when shooting, and it required a fork stick to stand on the ground and put the barrel on the fork to shoot.

At the same time, because of the excessive charge, the recoil of this gun is also quite "considerable", and only after special training, the mighty guy can stand the recoil of this arquebus!

In fact, the Mushkert arquebus was originally used to defend the city and was used as a light artillery.

Wang Qi imagined that when he was facing the enemy, he summoned the air gun, and then the projectile in the barrel was rapidly discharged under high pressure, and the barrel itself retreated rapidly under the action of Newton's third law (action and reaction force). Because of the need to aim, he needs to keep the barrel in line with his eyes when greeting the barrel, and the final result is that the enemy misses it and is not clear, and his own eyes must be inserted into the barrel of the gun that is rapidly retreating!

This terrible sight immediately made Wang Qi's back tingle, and he shivered on a hot day.

"Fortunately, I didn't buy the right lead bullet, otherwise Lao Tzu would definitely be glorious when he tried the gun!

"If you are not glorious, you will become a one-eyed dragon!"

Unable to buy a suitable lead bullet, Wang Qi initially wanted to replace it with steel balls. Steel balls are not controlled items and are easy to buy.

But the example of the Mushkert arquebus quickly put out this thought. A steel ball with a diameter of 22 mm is probably not light. In order to make the steel ball form enough lethality, it is necessary to increase the chamber pressure and give it enough muzzle velocity.

And the higher the chamber pressure, the stronger the recoil! His air gun only has a bare barrel, and there are no accessories or stocks, once the barrel containing high-pressure air is placed in real space, the high-pressure air loses its restraint, and the projectile will certainly go forward, and the barrel will fly backwards like a sharp sword.

"Then, Lao Tzu is going to be a tragedy!"

"Or, can you not aim with your eyes, and don't let the summoned steel pipe be in a state of volley, directly summon it into your own hands, and use both hands to fight the recoil generated when the projectile is fired?" Wang Qiyu was a little unwilling to give up these stainless steel pipes that he had so hard to get, and thought again.

But after careful consideration, I still gave up.

Because once the barrel leaves the cube, the high-pressure air inside up to several megapascals, or even tens of megapascals, will immediately take effect, instantly "explode", instantly accelerate the projectile and the barrel, this speed, although Wang Qi doesn't know how fast, but roughly guess at least the subtle level (thousandths of a second), which is far beyond his nervous reaction, the barrel will still crash into his weak body like a sharp sword!

At this time, he suddenly understood why modern firearms, whether air guns or gunpowder guns, are of very small calibers, air guns are about 4,5 mm, and pistols and rifles are only 5, 6, 8, 9 mm.

Even Barrett, the king of snipers, has no more than 12.7 mm of ammunition. He had seen the battle when Bartley fired the gun, and the shooter could only take a lying position, with the butt of the gun pressed tightly against the shoulder to cushion the recoil.

However, with almost twice the caliber of his steel pipe as the king of snipers, what the hell was he thinking?

"Well, that's it, I don't have to think about any air guns for now. These stainless steel pipes don't need to be thrown, they are temporarily placed in the cube and used as sticks for self-defense, or as tools to extend the length of their arms when launching the ultimate killer weapon, to reach the enemy. ”

Wang Qi's air gun, before it was fully made, was stillborn.

From this, he also learned an experience or lesson, that is, many seemingly simple things are not easy to fully put into practice.

Especially what he patted his head and imagined, it was not only far from his imagination, but even dangerous.

For example, the miniature version of the "air bomb" he made yesterday without fragments frightened him a lot, damaging a lot of flowers and plants, not to mention the shock wave generated when the compressed air was decompressed, and directly blew him to the ground! Fortunately, there was nothing in the compressed air, otherwise, he would probably "die before he was born"!

For another example, the air gun he got out of last night by patting his head completely ignores the action and reaction forces, and also ignores the importance of caliber in firearms. Fortunately, he didn't conduct the experiment, otherwise, the consequences would be really unimaginable!

If you don't die, you have to be crippled!

If he didn't go to the steel market to buy a steel pipe as a barrel at that time, but directly borrowed the barrel of the air gun in reality and reduced the caliber, not only would he not fall into the embarrassing situation of "having a gun but no bullet", even if he did a live shooting experiment, even if he ignored the recoil, he would not be in any danger because the caliber of the air gun was too small, the muzzle velocity of the projectile was not high, and the recoil generated was not large.

Haven't heard of how much recoil an airsoft gun has!

————————————

Wang Qi, who was happy because he didn't make an air gun, and because he fortunately didn't make it, he "picked up a life" and then rejoiced about it, and it was already five o'clock in the afternoon when he got back to school by car.

As soon as he got out of the car, he received a call from Xie Zhifu, asking him where he was and why he didn't see anyone for a day and a night?

"I came back late last night and didn't get in the door. I went for a walk around the streets during the day today. Aren't you going to report to the company tomorrow? I want to buy a set of clothes to wear to work. Wang Qi casually talked nonsense.

Tonight is the last night of school, and a few of you are going to have a casual meal—a real casual meal, and you won't be drunk. Xie Zhifu said.

"Okay, Lao Xie, I have no opinion! I'm at the school gate now. You say the place, I'll go straight there. "Wang Qi has eaten the casual meal several times this month, in the class, in the tie, in the same bedroom, in the next bedroom, and in the friendship dormitory, for various reasons, he has participated in it several times.

But this kind of thing is always too much. Moreover, it is indeed as Xie Zhifu said, tonight's dispersal is the real dispersion. As soon as tonight passes, it means that everyone's college career is completely over, and from now on, the brothers who have been classmates for four years will go their separate ways, and whether they can see each other again in the future, that is really only God knows.

"It's still in the old place, the 'Educated Youth Brigade Captain Elder Hot Pot' at the back door. By the way, if there is a woman, bring the woman with you. Xiao Qi, Lao Tzu always feels that your baby is not right these two days. Hehe, honestly, are you really playing friends with someone?" Xie Zhifu smiled and asked with interest.

My girlfriend's mother-in-law hasn't given birth yet. Wang Qi replied directly.

"Quack! It turns out that your baby likes to eat tender grass! Or is it grass from the next generation! You are awesome! Work hard, Xiao Qi, strive to make the whole billionaire come out before the age of forty, and I don't mind letting my daughter marry you when the time comes!"

"Fuck off! As long as your uncle doesn't love your grandmother, the probability that your daughter won't be disabled is extremely low! Lao Tzu doesn't want to have nightmares at night!"

"Do you know a hammer! Do you understand genetic mutations? Lao Tzu has a hunch that Lao Tzu's daughter must be beautiful and beautiful!"

"Give me the trash can, I'm going to vomit." Why don't you close the moon and be ashamed?"
