Garden of Eden, a few days later.
Machining Sector, Research Laboratory.
With a "pop" sound, the extremely strong alloy cartridge case shattered again in a ball of flames. Richard shook his head slightly disappointed.
He has experimented with this many times and solved some problems, but it got stuck on the material of the bullet casing.
The cartridge case is filled with magic salt. The destructive power of this ultra-high-energy material far exceeds that of conventional explosives. Even alloy cartridge cases can still shatter. In this case, when the firearm is fired, not only the cartridge case cannot be ejected, but also metal fragments will be left in the barrel. In severe cases, the barrel may explode when subsequent bullets are fired.
There are some ways to solve it, such as strengthening the thickness of the cartridge case and replacing it with stronger alloy materials.
But this will inevitably increase the size and weight of the bullet. If a bullet is the same size as a cannonball, what bullets are needed? Wouldn't it be easier to just make the cannonball
Richard sat in front of the processing table in the research room, tapping the surface of the processing table with his fingers, making a "plop tap tap tap tap" sound, and kept thinking.
What he urgently needs now is a light and extremely strong metal material to make the shells of magic bullets. However, this kind of material is difficult to find, or it is difficult to make it if it meets the conditions.
What to do
Are we going to get stuck here
Richard thought for a long time, then suddenly had a thought, raised his eyebrows, and said to himself: "Isn't it a bit over the top? If many metals cannot meet the requirements of magic bullets, then wouldn't it be good not to use bullet casings?"
Yes, no shells required.
Caseless bullets!
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 bullets, force-loaded bullets, signal bombs... and so on.
But if you divide them according to whether there is a cartridge case, it is very simple. There are only two types - cased cartridges and caseless cartridges.
Most of the popular bullets on the earth are cased bullets. According to history, the earliest ones that appeared were caseless bullets.
Caseless ammunition refers to an ammunition design that abandons the cartridge case and directly molds the bullet charge into a solid block to connect or contain the warhead.
In the early days of firearms development—during the American Civil War when muzzle-loading muskets were popular—in order to increase the rate of fire and simplify loading, some people packed propellant and primer into paper cases. When fired, the paper shell burns together with the propellant, and there is no need to eject the shell. It is considered the prototype of a caseless bullet.
Later, firearms continued to develop, and cased ammunition slowly replaced caseless ammunition due to reasons such as reliability and performance. However, after World War II, the United States, Germany and many other countries invested a lot of energy in research on caseless bullets.
This is because caseless bullets have many irreplaceable advantages over cased bullets.
The caseless bullets developed after World War II are not the paper-cased bullets used during the American Civil War. Instead, a certain proportion of flammable and residue-free adhesive is mixed into the propellant to first make a complete propellant column with a certain strength. Then, fix the warhead on the end of the grain column, fix the primer on the other side, 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, due to its small size, light weight, and no need to eject the shell, the rate of fire will be greatly improved in the shooting system, and the recoil will be significantly reduced.
Take the G11 caseless rifle developed by the more influential German HK company as an example. Its continuous firing rate can reach 600 rounds/minute. And if it is a three-shot burst fire, 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 after another. Because the recoil is extremely small, the impact points of these three bullets are very concentrated and the accuracy is extremely high, far exceeding that of shelled bullets fired by ordinary rifles.
Of course, cased bullets also have many shortcomings, otherwise cased bullets would not be popular.
First of all, it is more dangerous to store and transport. After all, it is a propellant column structure, which is not as strong as a metal cartridge case. It can easily break or explode if it is hit by a collision.
And once it explodes, it will be surrounded by exposed pillars of explosives, and the consequences will be unimaginable.
In addition, there is the problem of spontaneous combustion of propellant.
Generally speaking, when a shelled bullet is ejected, part of the heat generated by the bullet can be taken away and the temperature of the gun bore can be reduced. Caseless bullets do not need to be ejected, so they naturally do not have this effect. If fired continuously, the barrel of the gun will continue to heat up and eventually become very hot.
Caseless bullets do not have the protection of the cartridge case. The propellant is directly exposed to the outside world. If the temperature of the gun bore is too high, it is easy to automatically ignite the propellant, causing spontaneous combustion and misfire.
However, in Richard's opinion, these problems are not a problem.
For example, regarding storage issues, he could store the ammunition in the space iron ring and take it out when needed. It was convenient enough and there was no need to worry about collisions.
If the gun bore temperature is too high, a cooling system can be made to solve the problem. It doesn't need to be as troublesome and complicated as water cooling or air cooling. Just use magic patterns to simulate the spell effect of the water-based ice branch. After all, bullets have been upgraded to spell bullets, and it is natural for firearms to be upgraded to spell firearms.
In this case…
Richard stood up and started busy.
…
In the blink of an eye, many days later.
Or the Garden of Eden.
A testing ground for spells in the Garden of Eden.
After the tragedy that occurred last time when testing the power of Alloy 237, Richard learned from his experience and completely renovated the spell testing field.
The biggest aspect of the transformation is to reduce the overall height of the test site.
In other words, Richard dug a huge pit and put the spell testing field in it. In this case, the residual power of the spell test will be a problem just to get out of the pit. Even if you successfully get out of the pit, the power will be greatly reduced, and it will be difficult to bulldoze many buildings in the Garden of Eden.
At this time, at the Garden of Eden Spell Testing Ground, Richard stood at the bottom of the pit and looked ahead more than thirty meters away. There was an alloy human-shaped metal target there, which was extremely strong.
After watching for a long time, Richard took out a pistol.
The shape of this pistol is extremely rough, with a long and thick barrel at the front, and a small and exquisite handle attached to the back.
Other than that, nothing more.
Well, no more - no trigger, no firing pin, nothing. This is because Richard's newly designed caseless bullets are somewhat different from the caseless bullets on Earth.
The projectile is 315 alloy, there is nothing much to say about this.
The pill behind the projectile is made of magic salt and a special kind of mucus.
The name of the slime is lava blood, which is taken from the secretion of a demonized toad and is used by many wizards as a casting material for fire spells.
This mucus is extremely viscous. After solidification, it is extremely hard. After a very small amount of mana or free energy elements are injected, it can be burned in a super short time.
Richard combined this mucus with magic salt, without setting up 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, there is a high chance that subsequent bullets will continue to hit.
Of course, for Richard, the most important thing is the power of caseless bullets.
Richard continued to hold the pistol with a huge barrel in one hand, and took out a caseless bullet with the other hand. He opened a notch on the back of the pistol, pressed it in, and then closed it.
After finishing preparations, Richard raised his hand, held the magic pistol, and aimed at the human-shaped metal target.
