Then there are still holes under the guardrail, a stick and a strap. Yang He is happy. The second style of the Xin'an gun is basically the same as a single-shot rifle in later generations.

He looked at it repeatedly, and everyone next to him was whispering, especially Qian Sanniang looked at the musket in Yang He's hand and was eager to try it out.

"My husband, give it." Zhang Chuxun handed over another box of fixed-packed paper-case ammunition.

Yang He picked up one. This is the new style of the medicine set in Xin'anzhuang. It is different from the original one. Not only are they used new gunpowder, but they are also using single-headed bullets.

The new opponent in the future is the Qing army, which is well equipped and has a high armor rate. In order to deal with their shields, armor, shield vehicles, etc., Yang He decided that the musket soldiers would use single-headed bullets in the future.

The shape of this bullet is like a hollow semi-cylinder with rifled around the bullet. It can rotate slowly after it flies out of the muzzle. The principle is similar to the badminton during flight. It relies on the forward movement of the center of gravity and its own slight rotation to maintain stability. The accuracy and degree of armor-breaking are much higher than before.

They are not difficult to cast, just need to have the corresponding mold, and even the rifle can be processed on the mold in advance, although the casting is a bit rougher.

In order to improve the penetration of the single-headed bomb, Yang He also added a certain amount of tin to the lead liquid to increase the hardness.

In order to prevent the single-headed bullet from deforming after ejecting out of the bore, cork is stuffed into the cavity of each single-headed bullet, which acts as a function of holding air and moving the center of gravity forward.

Of course, the single-headed bullet has a certain degree of accuracy, but the level is not too high, and it is basically no accuracy a hundred meters away. But to Yang He, this distance is enough, anyway, his army basically fights within a hundred steps, and it is useless if it is far away.

He looked at the medicine in his hand, and the total weight of gunpowder was about six cents and five cents, internal gunpowder was one cents and five cents, and lead bullets were five cents.

The second type of his Xin'an gun is still twelve mm caliber, but with a long single-headed bullet, even if the bullet is hollow, the bullet will be much heavier, about 18 grams.

Such a heavy bullet requires more gunpowder to reach its original power range, but Xin'anzhuang uses new gunpowder, which is the willow branches around the Qingming Festival, so that the charcoal can be burned thoroughly without any wood properties.

Sulfur is also refined and purchased. With the original purity of nitrogen, the gunpowder produced is more exquisite and high-purity.

Zhang Chuxun reported that it turned out that gunpowder could break armor by more than 60 steps, but now it has increased to 70 steps.

Moreover, even if you use a single-headed bullet, the amount of gunpowder will be reduced to one or five cents, which only takes half of the original one. The smoke produced is still white and slightly white, completely different from the thick smoke of others and black smoke covers the eyes.

There are many impurities in gunpowder, and after shooting, black smoke will roll. The fine black gunpowder will be white.

"Try it."

Yang He picked up the gun, and the metal sounded brittle, and the downward copper bolt was raised.

Yang He pulled it, and in the sound of metal, the copper plug was pulled out together with the iron cover, revealing the black vault.

Yang He stuffed the single-headed bullet paper case hard in. With a push, the copper bolt was pushed away with the iron cover. The copper bolt mouth was easily pushed into the barrel. Looking at the iron cover, he also wrapped a part of the back of the barrel.

Yang He pressed and with a whistle, the iron cover did not move, and the copper trunk turned right and stuck in the hardwood empty groove wrapped in the iron. At the same time, the arc knife at the front of the copper trunk cut through the fixed paper tube ammunition in the gun chamber, and the rustling medicine poured into the fire door nest.

He pushed the hammer down, raised his gun and aimed at a target seventy steps away, aimed for a while, and pulled the plate machine.

With a loud bang, the gunpowder filled the smoke, and the hammer hit the ignition sickle with force. The continuous Yin and Yang machine dodged, and the hot iron filings fell into the fire gate nest, igniting the inducing medicine inside.

Raging fire lights rose from the fire gate nest and the mouth of the gun barrel, and white smoke rose.

"good!"

Everyone shouted loudly, looking at the target, they were hit accurately, and debris flew.

Yang He looked at the square and felt that after using a single-headed bullet and new gunpowder, the power had indeed increased a lot.

He estimated that the initial speed was close to 300 meters per second, and it was indeed within seventy steps, which was about 100 meters, which could break the enemy's single-layer iron armor, iron-inserted cotton armor, etc.

If the enemy enters a distance of fifty steps, they can break their second-level heavy armor.

If they approach forty steps, it would be useless to wear three layers of armor.
