Li Huaishu gave an order and more than a dozen grenades were thrown out.
These hand grenades are filled with chemical fertilizers and sawdust made of soil chemicals, and their power can reach 60% of the ladder.
The shells of grenades are made of cast iron with high phosphorus content.
This kind of iron with high phosphorus content is very brittle and must be discharged during iron making, otherwise the iron will be useless.
But this kind of very brittle iron is very suitable for making bomb shells, because it is so brittle that it can form a lot of fragments, which are evenly distributed in all directions after the explosion.
Very lethal.
After the grenade flew out in a fan shape, everyone immediately fell down to prevent being blown up.
The Fortune Ship is tall at both ends and low in the middle. The middle part is just slightly lower than the flat-deck Star.
So as long as you lie down in time, you won't be injured by the fragments.
Suddenly, there was a violent explosion on the ship, and the Marines on the bow even felt the flames rushing through their backs.
A plume of black smoke rises from the lucky boat.
Two of the three masts were blown down.
The sails on these masts were burned when the pirates chased them, and the masts were also seriously attacked.
In order to force Fu Ship to stop, the pirates focused on attacking the mast and sails.
These masts were no longer strong, and two of them fell completely this time under the bombardment of grenades.
After the main mast fell, it almost missed the Star, which shocked everyone.
While the smoke was still lingering, fifty people quietly touched it.
After the explosion, there were screams on the Fuzhou ship. When the ship hit the ship just now, the pirates retreated towards the bow and stern of the ship.
Just covered in grenades.
At this time, except for the Japanese pirates who were injured during the collision, there were people everywhere who were knocked down by grenades.
There was chaos at the bow and stern.
After Li Huaishu and others boarded the boat, they quickly rushed to the stern to control the steering gear.
The strong sea breeze quickly blew away the smoke. Kurokawa Ichiro at the stern huddled in a corner and escaped the grenade attack just now.
Seeing that Akito had actually boarded the lucky ship, he quickly called out and asked the iron gunner who had just retreated to the stern of the ship to come forward and shoot.
Immediately, more than seventy iron gunners quickly ran to the front of the ship's stern building, used the railing board as a cover, and fired at the rushing Ming army.
Bang! Bang! Bang! After a burst of smoke.
Kurokawa Ichiro's eyes widened and he carefully observed the results of the battle.
He found that the results were basically zero.
The front of the Marines on the opposite side were pushing their iron-clad shields forward slowly, and the second row was also holding their iron-clad shields diagonally.
He didn't know that these shields were covered with three millimeters of carburized and hardened steel plates.
The 13mm soft lead bullet of the iron cannon cannot penetrate the 3mm carburized and tempered hardened steel plate.
After all, lead bullets are too soft.
Moreover, the gunpowder they used was not good, and was far from the level in Zunhua. In fact, the gunpowder in Japan at this time was also very different from that in Europe at that time.
The fifty soldiers who boarded the ship were arranged in five rows, ten per row.
The first row held their shields flat, and the second row held their shields diagonally above the first row's shields, basically protecting the front and top.
The third row stretched out a nine-fire door gun from the gap in the shield.
The last two rows held shields toward the back, thus protecting the front, back and top.
A row of ten soldiers, like a turtle shell, tightly guarded against the threat of Japanese pirates.
Because Li Huaishu knew that the Japanese pirates had no artillery, he dared to arrange his troops in this way.
If the Japanese pirates had artillery, they could only divide into ten groups and charge hard.
"Fire!" Li Huaishu gave the order, and ten nine-shot guns opened fire like exploding beans.
Bang! Bang! Bang!
Gunshots rang out continuously.
The railing on the stern of the ship was only one inch thick and could not block a fire cannon shot at such a close range.
Yang Fan's musket has now adjusted the black fire medicine to the optimal formula, and it is maroon, wet, and granulated.
Uniform propulsion and combustion efficiency are optimal.
Each lead bullet is a fixed-loading bullet. Just insert it into the barrel one by one and load it quickly. This also avoids the disadvantages of overloading or underloading the black fire powder in a panic.
In order to enhance the armor-piercing power of the fire door gun.
The lead bullets distributed this year are all made of lead on the outside and steel balls on the inside.
Although the portal gun is a smoothbore gun without rifling, the tail of the lead bullet still takes the shape of a funnel. This type of bullet is called a mini bullet.
It was originally an invention of the era of rifled guns.
Such a bullet tail shape allows the soft lead to expand and seal the gap with the gun bore when fired, preventing air leakage and increasing the muzzle velocity and range.
In this way, the muzzle velocity of the smoothbore gun will be faster than that of the rifled gun, and the power will naturally be greater.
Speaking of this, there is a misunderstanding in everyone's understanding. Everyone thinks that a rifled gun has a longer range than a smoothbore gun. In fact, this is wrong. Because of the rifling, the resistance of the rifled gun is large, and a lot of the propelling force of the propellant is wasted. Its
The muzzle velocity is far less than that of a musket.
Armor-piercing power mainly depends on muzzle velocity.
So why do everyone say that rifled guns have a longer range than smoothbore guns?
Because the range mentioned here is the effective range, not the maximum range.
Rifled guns have gyroscopic stability because the bullets fly out while rotating, so they can accurately hit the target at a longer distance.
For example, a smoothbore gun has a maximum range of 500 meters and an effective range of 90 meters; a rifled gun has a maximum range of 400 meters and an effective range of 150 meters.
The difference lies here.
Therefore, in order to further improve the power of armor-piercing projectiles and increase the muzzle velocity, modern tank guns have replaced rifled guns with smoothbore guns.
Although the British are still sticking to it, they value accuracy more.
But accuracy is meaningless at close range.
If it can't penetrate, what will happen if it gets hit.
I heard that their next-generation main battle tanks will also be replaced with smoothbore cannons.
Within thirty meters, the fire door gun is as powerful as the matchlock gun and the rifled gun. The accuracy is meaningless because the shooting distance is too close.
At this time, higher muzzle velocity means stronger penetration.
Penetrating power represents the ability to penetrate armor.
Ten nine-shot guns fired ninety bullets in a row, and the fierce firepower directly blinded the Japanese iron gunners.
This chapter is not over, please click on the next page to continue reading! These seventy iron gunners are well-trained because they are all old gangsters at sea.
After firing the first shot, without even looking at the result, he immediately took out the medicine bottle from his body and started pouring gunpowder into the muzzle of the gun. He filled it with gunpowder, then put in lead bullets and filled it with gunpowder again.
They are not the regular army of Japan and can only reach the level of three rounds in two minutes. In fact, this level is already very high among pirates.
Many pirates use matchlock guns, with a rate of fire of only one shot per minute. Some pirates are even so poorly trained that it takes several minutes to fire one shot.
The key is that after firing the first round, reloading is too cumbersome and slow.
There are more than thirty actions in this process, and there must be no mistakes. Otherwise, if one step is wrong, the next shot will not fire.
Because it was a muzzleloader, they had to stand while loading, so their upper bodies were all exposed to the Marines' muzzles.
In less than ten seconds, ninety rounds of lead-coated steel core projectiles came over like a storm.
Although the accurate range of the fire portal gun is only 9.1 meters, on the ship where the distance between the two sides is only more than ten meters, the competition is about who has the strongest firepower and who has the fastest rate of fire.
The ship's railings could not stop the steel-core bullets, and they passed through one after another, causing wood chips to fly all over the sky.
Suddenly there was a howl at the stern of the ship, and rows of people fell down like wheat.
Some were hit in the chest, some in the stomach, and some were directly punched through the head.
Because lead-coated steel-core bullets are composed of two materials with inconsistent weights and centers of gravity, they will immediately lose stability once they enter the human body.
As a result, the projectile shatters, rolls, and explodes under the huge resistance, directly tearing the internal organs into pieces, creating a terrifying cavity.
If it hits the limbs, the muscles, tendons, and bones will be shattered and mixed into a mess.
The person immediately lost his ability to fight.
He could only fall to the ground and cry.
If hit in the torso, there is basically no chance of survival.
Ichiro Kurokawa was spared because he was standing on the highest bridge and was not attacked.
He looked at the man who was reloading and fell nearly half way down. The fire cannon on the opposite side could be fired continuously in a short period of time, and his eyes widened in disbelief.
