The Congreve rocket was finally tested, and everyone present breathed a sigh of relief, especially Director Lu, who was deeply glad that he had only prepared two test rockets - God is pitiful, with his understanding of his second cargo owner, Buchen would definitely continue to test if there were any extra rockets......

After the rocket test, the next thing to appear on the scene is undoubtedly the steel rifled gun. Pen & Fun & Pavilion www.biquge.info

There are many advantages of rifled guns over smoothbore guns, first of all, because the shell rotates at high speed in the chamber, the muzzle velocity of the shell is much faster, and the muzzle velocity is faster, and the penetration will naturally become stronger! And because the shell is disemboweled after rotation and acceleration, its ballistic stability will be much better, and if the stability is good, the accuracy will naturally come up, and there will be no more smoothbore guns that point to the east and west, and the attack efficiency will be greatly improved!

As for the shortcomings, there are also some disadvantages! First of all, it is much more difficult to manufacture, because it is necessary to pull the spiral rifling in the gun chamber! Don't think it's an easy task, first of all, the rifling must be regular, and the distance and shape between each turn must be the same, which is almost impossible for some handicraft workshops that lack machine tools! The reason why it is said is almost, because some extremely skilled old craftsmen can still do this, but there must not be many such people in the world, and because of all manual work, the efficiency will not be high, but the cost will be very high, especially the labor cost, so even if the rifled gun can be manufactured, it is impossible to produce large-scale production and equipment troops, and it is impossible to equip the troops in large quantities.

In addition, there is the problem of materials, if you use wrought iron to make rifled guns, because wrought iron is soft, even if the rifling can be pulled out, it will be smoothed out after a few cannons. And if it is made of hard but brittle pig iron, the processing tools alone are enough to cause a headache! Just kidding, pig iron is so hard, with ordinary processing tools, maybe the rifling has not been pulled out, and the tool is worn out first......

Moreover, pig iron is brittle and has poor toughness! However, rifling will undoubtedly affect the structural strength of the barrel itself, so even if the pig iron rifled gun is made, its reliability is also questionable, and it is necessary to find ways to increase the strength of the barrel.

Therefore, the best material for making rifled guns is actually steel with good hardness, toughness, and durability! Just because the hardness of the steel is not bad, it is also difficult to process!

And the steel rifled gun that is being manufactured now is the crystallization of successfully overcoming all kinds of technical difficulties! Although it does not use metal fixed ammunition and is still an old-fashioned breech gun in essence, it has an epoch-making significance just because it has two characteristics: steel and rifling!

"What caliber is this cannon?"

Buchen came to the small steel cannon under test, and asked Director Lu who was accompanying him with an interested expression.

Director Lu immediately replied: "Back to the lord, this cannon is a 60 mm caliber!" According to your meaning, the caliber is used for rifling classification, and the bullet weight is used for smoothbore classification. ”

"Hmm." Buchen nodded, very satisfied with Director Lu's answer.

"Where's the ammunition?" Buchen asked again.

Director Lu hurriedly gave the craftsman in charge of the cannon a look, and the craftsman immediately kicked open the ammunition box, took out one from the neatly stacked paper shell fixed ammunition, and respectfully handed it to Buchen with both hands.

"There is labor!"

Buchen nodded to the craftsman with a smile, reached out and took the paper shell bullet, tore it open, and found that in addition to the ~ projectile, it was a large cylindrical iron lump with a pointed tip.

Buchen rubbed the big iron lump with his hand, and it felt like it was about the same weight as a twelve-pound cannonball.

This kind of shell is called a mini bullet, and it is completely the same thing as the mini bullet used in rifled guns, but because it is used for guns, it is relatively large.

"It's a pity that there are still no flowering bombs!"

Buchen said with a look of regret, the penetration of rifled guns is too strong, in addition to firing this kind of solid ammunition is particularly good when bombarding bunkers, Buchen feels that it is not as strong as smoothbore guns, at least smoothbore guns can cause a lot of damage to the enemy's military formation!

"Lord, the development of the flowering bomb is already a bit eyebrow-raising!" As soon as Buchen's words fell, Huang Daoshi, director of the ammunition research and development department, came up and said.

Buchen glanced at the Zodiac Daoist, although this benevolent brother is not good-looking, but he is indeed a generous and righteous person, all the way from the Beijing Division to follow him to the four towns of Wushan, looking at the Zodiac priest and them, Buchen sometimes can't help but sigh, he Xiao someone how can he be, and his command can gather such a group of loyal and righteous people!

"Got some eyebrows?" Buchen asked excitedly, "To what extent are you now?" ”

"Back to the lord, Poor Dao and his colleagues have perfectly solved the problem of the lead, as long as it takes a little longer, the foundry department of the arsenal has come up with the standard shell of the cannonball, and it can be officially tested! And when the time comes, it will also be possible to supply flowering ammunition for smoothbore guns! The zodiac said with a fluttering eyebrow.

The flowering bomb is actually a high-explosive bomb, which is the "he" that military game enthusiasts often hang on the verb, and its ultimate form is a modern artillery shell with an all-metal fixed ammunition and a bump fuse, however, Buchen definitely can't play this kind of high-end stuff at present!

All Buchen can do is make a small "Heaven-Shaking Thunder", which is the kind of thing he killed the Eight Kings of the Western Continent, although this kind of Sky-Shaking Thunder also has a metal shell, but its biggest problem is that it cannot be detonated when it hits the target.

Well, that's not accurate either. By trimming the length of the external lead, there is also a certain chance that the shell will explode exactly when it hits the target, although the probability is pitiful, but it is enough for the current minister. After all, his current enemies are not particularly awesome guys, and the difference between whether the shell explodes when it hits the target, or whether it explodes after hitting the ground for a second or two, or the volley explosion is actually not very big......

"You're doing a great job! When the shells are made and accepted, I will give you the reward you deserve! Buchen promised to the Zodiac priest.

"Thank you, my lord!" The zodiac priest hurriedly thanked him.

After talking about the flowering bomb, Buchen turned his gaze to Director Lu and ordered, "Let's start testing!" ”

"No!"

Director Lu hugged his fist at Buchen, followed by a routine gesture of resignation.

"Lord, please go into the bunker and watch!"

Buchen shook his head with a wry smile, and took his companions and the two regiment leaders into the bunker hut again.

After Buchen and other important people were ready, Director Lu gave instructions to the craftsmen who were handling the guns: "Start testing!" ”

The craftsman nodded, and immediately took out a paper shell bullet from the ammunition box with his hands and feet, tore it open, first poured the ~ projectile into the muzzle, compacted it with a large strip, and then stuffed the Mini bullet into the muzzle, and finally, corrected the muzzle, so that it was aimed at the target in the distance, and then picked up a red-hot iron chisel from the iron furnace on the side and inserted it into the fire door at the tail of the artillery!

"Boom !!"

The sound of the cannon, which was sharper and sharper than the smoothbore cannon, suddenly sounded, like the sound of gold and iron clashing! After a high-speed rotation, the solid Mini bullet in the barrel immediately flew out of the barrel with an extremely fast muzzle velocity and shot straight at the target two hundred paces away!

One step is almost equal to 1.5 meters, and 200 steps is 300 meters, and at this time, 300 meters away, a 20-millimeter-thick steel plate has been erected and fixed.

In an instant, Mini's cannonball slammed into the steel plate with a crisp sound, and it passed through without stopping, leaving a palm-sized hole in it!

"That's amazing!"

Buchen, who saw this scene through the observation hole, couldn't help but exclaim, you must know that the reason why Director Lu used a 25-millimeter-thick steel plate to test it was not a random idea of patting his head, but it was very targeted!

Twenty millimeters thick homogeneous steel armor, what is equivalent to this world? Buchen, who is proficient in fighting energy, naturally understands that the maximum protection power of his tenth-level demon blood weapon is almost this number!

In other words, a world-strong man with a tenth-level elemental armament can be sniped by a rifled cannon from a distance of three hundred meters!

After understanding this, Buchen was both happy and afraid, there is no doubt that from now on, gunpowder weapons can also pose a deadly threat to him!

It's just that the test has just begun!
