The Great Liang lacked war horses and was extremely passive in the course of the battle against the northern nomads. Therefore, the imperial court attached great importance to the development of weapons, especially long-range strike weapons, and invested manpower and material resources in the beam, and also achieved good results.

The crossbow arrows in cold weapons have reached their peak in terms of stability and range. Thermal weapons have also begun to take shape, except for the grenades designed by Li Yue, artillery can already be put into actual combat. In addition, Li Yue has proposed to add heavy stones to the casting of cannons to solve the problem of easy explosion, and I believe that artillery will definitely be able to show its might on the battlefield in the future.

However, artillery also has a fatal flaw in this era, that is, it lacks mobility. It is good to defend the city, but it is inconvenient to pursue the fleeing enemy. That's why Li Yue remembered a musket that was easy for individual soldiers to carry.

But this thing of the musket is obviously a new thing in Daliang, so Feng Chaozong and Jiang Hongfeng both lay on the drawings and looked at them for a long time.

It was Lao Jiangtou who saw the door first, and he picked up the drawing of the musket from the table and said, "This thing seems to be somewhat similar to the spitting musket developed by the Ordnance Superintendent before." ”

"Spit muskets?" Li Yue couldn't help asking.

"Of course, it's nowhere near as sophisticated as the muskets designed by the adults." Jiang Hongfeng thought for a while and replied: "It is to put gunpowder, lead beads, iron sheets, etc. into a bamboo pipe barrel, insert a fuse into the opening at the back end, and then ignite it to spray out the filling." When fired, the nozzle is accompanied by flames, so it is called a spitting musket. However, the range of this object is only about ten steps, and its lethality is limited, so the ordnance supervisor has never made it again. ”

The weapon manufacturing of the girder is really advanced! Li Yue couldn't help but praise in his heart, the spitting musket that Lao Jiangtou said was very close to the modern tubular musket. It's just that due to the limitations of the times and technology, no one has yet been able to see the great promise of this technology.

"My lord, why is there such a spiral trunking in this barrel? This increases the difficulty and cost of production. Lao Jiangtouyou looked at the drawings in his hand and continued to ask.

"The function of rifling is to allow the bullet to rotate, improving the range, stability, and penetration of the bullet." Li Yue patiently explained: "Rifling is actually not difficult, what is needed is patience and meticulousness. ”

Then Li Yue introduced a simple manual wooden mechanical bed to Feng Chaozong and Jiang Hongfeng, and the early American colonists made rifling, which was used by the early American colonists to make rifling by themselves by hook knife broaching method.

This hook knife broaching method is to place the hook-shaped cutter on the steel tie rod that is slightly thinner than the diameter of the gun chamber, and the height of the hook-shaped scraper cutting edge can be adjusted by adjusting the screw of the tie rod layer; Each time the pull passes through the barrel, the lever moves a little, and with the uniform rotation of the barrel, a certain winding rifling wire is drawn, and after reaching a predetermined width, the second rifling is pulled in a different position. Pulling a rifling line needs to be broached dozens of times, and the more times it is pulled, the finer and more precise the drawing groove is formed.

Even if there is no flintlock musket, the current weapons of the Great Liang are ahead of the surrounding neighbors, so the need for flintlock muskets is not very urgent, in this case, Li Yue naturally asked them to develop the highest level of muskets that can be achieved at present.

Straddle the smoothbore gun and directly make a front-loading rifled flintlock pistol.

The bullet should be developed, and naturally it is also the best Mini bullet in the development of preloading.

In his previous life, as a military fan, Li Yue was very familiar with firearms, and the breech pin gun had a faster rate of fire and greater power, he didn't want to engage in it, but there is a key technology for breech guns that has not broken through now, that is, thunder mercury, and only with thunder mercury can you make a fire cap.

Li Yue probably understands the production method of thunder mercury, which is to dissolve mercury in nitric acid to form mercury nitrate, and in the presence of excessive nitric acid, it reacts with ethanol to form thunder mercury.

The problem is that nitric acid and ethanol can be directly obtained in the later generations, but it is not easy to get these two things in Daliang, and he can only tell Feng Chaozong and Jiang Hongfeng the method, and let them organize craftsmen to experiment slowly, and when they can get it out, the ghost will know.

As a result, he could now only make front-loading flintlock pistols with mini rounds.

These two are the ultimate in front-loading rifles, and with such weapons, the girder is enough to sweep the world.

Mini bullet is a kind of cylindrical shell lead bullet, this bullet is slightly smaller than the caliber of the rifle, can be easily pushed into the chamber with a push lever, greatly improving the rate of fire, solving the problem that the front rifle is reloaded, due to the bullet is too large to cause the barrel to be plugged, or the barrel is blocked.

The mini shell is surrounded by threads to match rifling, and there is a conical cavity at the bottom of the bullet, which is blocked with a wooden plug; When firing, the gunpowder gas hits the wooden plug, compresses the wooden plug and squeezes it into the cavity, forcing the bottom of the bullet to expand rapidly, close to the rifling, close the gap between the bullet and the gun chamber, so that the gas cannot leak out; It can also make the warhead rotate at high speed under the pressure of rifling, and improve the range and accuracy of the bullet.

In the original history, before the appearance of the mini bullet, the smoothbore gun was a practical weapon, while the rifled gun was only an experimental weapon, and the main problem of the rifled gun was that due to the rifling engraving, it was difficult for the front-loading bullet to keep the chamber closed, and the power was greatly reduced.

In order to achieve good breath-holding, rifled gun bullets tend to be made of the same caliber as the gun caliber or slightly larger, so it is extremely difficult to load; It is often necessary to hammer the pusher lever with a hammer to propel the bullet into place, which often results in a more dangerous rifle rupture. With Mini Bullets, none of this is a problem anymore.

Li Yue also stressed to Feng Chaozong and Jiang Hongfeng some questions about the idea of producing bullets.

When making bullets, the steel mold is divided into two pieces, and each steel mold can have ten warhead die holes. To use relatively soft lead as raw material, it is softer after heating to a certain extent, it can be directly pressed into the bullet mold, made into the shape of a warhead, and after cooling, lift the upper piece of the steel mold, take out the formed bullet, and then manually add the wooden plug at the bottom of the warhead.

Although it is a bit cumbersome to make it this way, in the era of hand-made, this is already the fastest way that Li Yue can think of.

After saying this, Li Yue thought about it, and finally advised: "The bullet is slightly smaller than the gun chamber, but there must be a sense of stagnation when stuffed into the chamber, if the production is not standardized, resulting in the bullet being too loose when stuffed into the chamber, you need to stuff the paper shell into the compaction to prevent the bullet from falling out when aiming." This will affect the reload speed in wartime. ”

"It's a bit complicated, but fortunately, the Ordnance Supervisor has gathered the best craftsmen from the Great Liang." Feng Chaozong patted his chest and promised, "I will definitely make a musket that satisfies Lord Li!" ”

"If you can really succeed in the trial production of such a gun, I will ask the bank to provide a special loan for your ordnance supervisor in the future to support your research and development of weapons."

Lao Jiangtou bowed to Li Yue, and then said firmly: "Then the loan is decided!" ”

"Haha!" The three of them burst into laughter in unison.
