Magus Tech (Technological Wizard)

Garden of Eden, a few days later.

Machining Sector, Research Office.

With a "pop", in a ball of flames, the extremely strong alloy shell shattered again, Li Cha shook his head slightly disappointed.

This has been his experiment many times, and some problems have been solved, but he is stuck on the material of the shell case.

The cartridge case is filled with mana salt. The destructive power of this ultra-high-energy material far exceeds that of conventional explosives. Even an alloy cartridge case can still shatter. In this case, in the firearm shooting, not only the shell casing cannot be withdrawn, but also metal fragments will be left in the barrel. If it is serious, it may explode in the case of subsequent bullet firing.

There are ways to solve it, such as strengthening the thickness of the bullet case and replacing it with a stronger alloy material.

But this will inevitably increase the volume and weight of the bullet. If a bullet is the same size as a cannonball, what kind of bullets are needed? Wouldn’t it be easier to make the cannonball directly?

Sitting in front of the processing table in the research room, Li Cha tapped the surface of the processing table with his fingers, making a "click, click, click" sound, and kept thinking.

What he urgently needs now is a light and extremely strong metal material to make the shells of spell bullets. But this kind of material is difficult to find, or it is very difficult to make it that meets the conditions.

So what to do?

Is it going to be stuck here?

Li Cha thought for a long time, then suddenly his thoughts changed, he raised his eyebrows, and said to himself: "Isn't it, a bit of a dead end? If many metals can't meet the requirements of magic bullets, then it would be better not to use bullet casings."

Yes, no shells.

Caseless bullets!

The bullets in this world, if classified according to their functions, can be divided into ordinary bullets, double-warhead bullets, armor-piercing bullets, tracer bullets, incendiary bombs, explosive bombs, blank bombs, strong loading bullets, signal flares... and so on.

But if it is divided according to the presence or absence of cartridge cases, it is very simple, there are only two types-cased bullets and caseless bullets.

Most of the popular bullets on the earth are cased bullets. According to history, the earliest ones appeared were caseless bullets.

Caseless ammunition refers to the ammunition design that abandons the cartridge case, directly makes the bullet charge into a solid block, and connects or contains the warhead.

In the early days of firearms development - during the American Civil War when front-loading muskets were popular,

In order to increase the rate of fire and simplify loading, some people put the propellant and the primer into the paper shell together. When firing, the paper shell burns together with the propellant, and there is no need to eject the shell, which is the prototype of a shellless bullet.

Later, firearms continued to develop, and due to reasons such as reliability and performance, cased ammunition gradually replaced caseless ammunition. However, after World War II, the United States, Germany and many other countries have devoted a lot of energy to research on caseless bullets.

This is because caseless bullets have many irreplaceable advantages compared with cased bullets.

The caseless bullets developed after World War II are not the paper shell bullets of the American Civil War, but a certain proportion of combustible and non-residual adhesive is mixed into the propellant, and a complete grain column with a certain strength is first made. Then, at the end of the powder column, fix the warhead, and fix the primer at the other end, and the final production is completed.

The biggest advantage of this is that it is small in size and light in weight, which can be reduced by more than half. At the same time, because of the small size, light weight, and no need to eject the shell, in the shooting system, the rate of fire will be greatly improved, and the recoil will be greatly reduced.

Take the G11 shellless rifle developed by the more influential German HK company as an example, the rate of fire for continuous shooting can reach 600 rounds per minute. And if it is three bursts of extreme speed, the short-term rate of fire can be as high as 2200 rounds per minute, which means that within 0.08 seconds, three bullets can be fired one by one. Because the recoil force is extremely small, the impact points of these three bullets are very concentrated, and the accuracy is extremely high, far exceeding that of ordinary rifles firing shelled bullets.

Of course, cased bullets also have many disadvantages, otherwise cased bullets would not be popular.

First of all, it is more dangerous in terms of storage and transportation. After all, it is a grain structure, which is not as strong as a metal bullet case. It is easy to break and explode when it is hit.

And once it explodes, it will be surrounded by exposed powder pillars, and the consequences will be unimaginable.

In addition, there is the problem of spontaneous combustion of propellants.

Generally speaking, when a cased bullet is ejected, it can take away part of the heat generated after the bullet is excited, reducing the temperature of the barrel. Uncased bullets do not need to be ejected, so naturally they have no such effect. If they are fired continuously, the chamber will continue to heat up and eventually become very hot.

Caseless bullets are not protected by shell casings, and the propellant is directly exposed to the outside world. If the temperature of the barrel is too high, it is easy to ignite the propellant automatically, causing spontaneous combustion and misfire.

However, in Li Cha's view, these problems are not really problems.

For example, the problem of storage, he can store the ammunition in the space iron ring, and then take it out when needed, which is convenient enough and does not need to worry about collisions at all.

If the barrel temperature is too high, a cooling system can be made to solve it. It doesn't need to be as troublesome and complicated as water cooling or air cooling. It's good to use the magic pattern to simulate the spell effect of the evocation-like water-type ice branch. After all, the bullets have been upgraded to spell bullets, and it is only natural for firearms to be upgraded to spell guns.

In this case……

Li Cha stood up and started to get busy.

...

In a blink of an eye, many days later.

Or the Garden of Eden.

Eden's spell testing ground.

After the tragedy of the 237 alloy test power last time, Richard learned from his experience and completely remodeled the spell testing field.

The biggest aspect of the transformation is to reduce the overall height of the test field.

In other words, Li Cha dug a super big pit and put the spell testing field in it. In this case, the remaining prestige of the spell test, just getting out of the pit is a problem. Even if it succeeds in getting out of the pit, the power will be greatly reduced, and it will be difficult to bulldoze the many buildings in the Garden of Eden.

At this time, at the Garden of Eden spell testing ground, Li Cha stood at the bottom of the pit and looked more than 30 meters away. There was an alloy human-shaped metal target there, which was extremely strong.

After watching for a while, Li Cha took out a pistol.

The shape of this pistol is extremely rough. What sticks out at the front is a long and thick barrel, and what is attached to the back is a small and exquisite grip.

Other than that, no more.

Well, no more - no trigger, no firing pin, nothing, because Li Cha's newly designed caseless bullets are somewhat different from the caseless bullets on Earth.

The projectile is 315 alloy, there is nothing to say about this.

The pill behind the projectile is made of spell salt and a special slime.

The name of the slime is the blood of lava, which is taken from the secretion of a demonized toad, and is used by many wizards as a casting material for fire spells.

This slime is extremely viscous, and after solidification, it is extremely hard. After injecting a very small amount of mana or free energy elements, it can burn out in a super short time.

Li Cha combined this slime with spell salt, without setting a primer at all, and planned to directly use free energy elements to stimulate it. In this case, the recoil will be lower. If it is a fixed target, as long as the first bullet hits, the subsequent bullets will have a high probability of continuing to hit.

Of course, for Li Cha, the most important thing is the power of the caseless bullet.

Li Cha continued to hold the pistol with a huge barrel in one hand, and took out a caseless bullet with the other hand, opened a notch on the back of the pistol, pressed it in, and then closed it.

After getting ready, Li Cha raised his hand, held the magic pistol, and aimed at the humanoid metal target.
