Zuihou produced about 1.2 kilograms of mercury from 1 kilogram of mercury, and the chemical team was very satisfied with this result. After all, the amount of mercury used in each fire cap is very small.

The fire cap used on the Minnie gun was preferably made of copper, and the traverser did not carry copper, and the Guangzhou advance station acquired a large number of Japanese red copper bars. This copper is very gunnery in the market because it contains a lot of silver. Refining silver can cover the cost of buying copper.

The metallurgical team refines the copper bars, resulting in copper ingots of high purity and small amounts of silver. After the raw materials were solved, the mechanical group designed and manufactured a machine dedicated to stamping fire caps, manufactured molds, and used electric power to drive 10 fire caps at a time.

After confirming that there were no problems with the serial manufacture of fire caps, the assembly of muskets began. These front-loading rifled guns, which used Mini ammunition, were assembled from 14mm alloy steel seamless tubes using high-pressure boilers purchased before departure. After the steel pipe was bought, he secretly pulled five "internal threads" entangled in 48 centimeters in the endless mechanical processing factory. Other hammers, triggers, reeds, etc. are also stamped out of 4~5 mm thick alloy steel plates in his factory. If they had not had this hand at that time, and had processed the rifling themselves, I am afraid that by now there would have been few rifled guns, and the new army would probably have to use brown bess -- this smoothbore gun was also touted by a group of madmen who lined up to shoot the partymen, and although Wang Luobin was also in line to shoot the partymen, it was not fundamentalist enough. The real queue to shoot the party is absolutely no rifled rifles.

The rifled gun is not a very new weapon, there was a flintlock rifled gun in the era of the flintlock musket, compared with the musket gun, the advantages of the rifled gun are obvious: the firing range is large, the accuracy is high, compared to the flintlock rifle with an effective range of less than 50 meters, the front-loading rifled gun can be used as a sniper rifle at that time in terms of shooting accuracy and range.

The biggest problem that it has not been popularized is that the process is complex and the cost is too large, and the second is the difficulty of reloading. The reason why rifled guns can shoot far and accurately is that the bullet must rotate along the rifling before it is discharged, which must be embedded in the rifling. Before there were no mini bullets, the bullet had to be slightly larger than the rifling diameter, and the bullet was deformed and embedded in the rifling by hitting it with brute force. The exaggeration is to hammer it in, and although in most cases it is more than that, but it is a fact that it is slower to reload than a smoothbore gun. Therefore, although it has been equipped with elite infantry on a small scale in many countries, it is not widely used.

It was the advent of the Mini bullet that changed the fate of front-loading rifled guns. Mini bullets, the diameter of the conical warhead is slightly smaller than the diameter of the breech, so it is convenient to reload. There is a conical cavity at the bottom of the warhead, a wooden plug blocks the bottom of the hole, and when firing, the gas presses the wooden plug to squeeze into the cavity, forcing the bottom of the bullet to expand, close to the rifling, and close the gap between the warhead and the rifle, so that the gas cannot leak out, and can make the warhead rotate at high speed under rifling pressure. The Mini bullet solved the problem of the difficulty of loading the front-loading rifled gun and the low range accuracy of the smoothbore gun, which made the rifle surpass the artillery and become the decisive weapon on the battlefield at that time.

Pulling the trigger, there was a loud "bang", and the gun body rushed backwards violently, and Wang Luobin hit his shoulder with pain. A faint smoke of gunpowder slowly emanated from the muzzle of the gun. Under the city wall 100 meters away, Jiang Ye ran out of the shelter, looked at the target, pasted the hole he had just punched with white paper, and then leaned into the bamboo tube to make the earthen phone and shouted loudly, Wang Luobin took off the earplug in his right ear, approached the bamboo tube on this urgent side, and heard him say: "9 rings, biased to 7 o'clock." So he raised his hand and motioned to hear.

This result is quite good! The first shot was very close to the bull's-eye, and it seemed that the gun would be calibrated in less than two hours. Pick up a small file and remove a thin layer from the left side of the brass notched base. Then loosen the vise that holds the barrel of the gun and load it with the fire and warhead. Start again and slowly aim at the bullseye of the half-body at a distance of 100 meters, and do another 100-meter calibration. Luck was good, everything couldn't have been more normal. After the distance of 100 meters is calibrated, several targets at different heights are used to simulate the test of 200 meters, 300 meters, and 400 meters. The longer the distance has to look at the RP of the soldier.

The gun took only 40 minutes to complete, and with a high level of accuracy, it was simply a perfect masterpiece. It is estimated that a single cavalry can be placed with a shot at a distance of 300 meters. Zuihou uses a soldering iron to burn his initials directly above the back edge of the butt, adding a "J+" to the bottom to indicate that this is a good gun that can be used as a sniper rifle. After all, even a Mini-rifled rifle only requires a 60% hit rate on a target that is 20 feet wide and 8 feet tall from 400 yards away.

Looking at the 4 orthography written with carbon strips on the wooden board, Wang Luobin added a horizontal next to the 4th orthograph. The group next to Zhan Wuyi also finished writing the fourth orthography. It seems that there is no problem with the production of 50 guns in today's class. It is estimated that a few more can be overdone.

3,000 steel pipes and fittings can make 3,000 rifles. There are also about 1,000 spare parts. However, two weeks ago, the Ministry of Industry decided to cut 20 barrels into short barrels of about 2 inches for the manufacture of Deringer pistols. Although there are 20 rifles missing, they can equip departments like the Navy and the Intelligence Bureau with self-defense firearms, and the GLOCK pistol is not intended to be issued to the natives.

Although the guns are assembled very quickly, more than 80 can be completed per day, but rifles that have not been strictly calibrated and handed over to rookie infantry who have not fired two live ammunition are really not much stronger than smoothbore burning sticks. The outside is strong and the middle is dry, which can probably describe the current embarrassment of the traverser.

It wasn't until they already had more than 600 guns that the industrial team was able to reduce their daily quota of guns a little and then take the time to carefully calibrate and select the guns for accuracy. The fire cap was carefully stockpiled for war. This is related to the operational policy of the General Staff. In view of the fact that the number of enemies will be very considerable once they arrive in the future, whether it is the Ming army or the pirates, there is no problem in dispatching thousands of people. The traverser is not as big as before, the stall has been spread very large, and the turtle flow of the fortified camp will cause a dilemma of being fortified everywhere and passive. The military's policy is to strike out, send infiltration units on the periphery, fire cold guns, lay mines, harass the movement of enemy brigades, and logistical transport. Such tactics require the front-line troops to be equipped with sufficient precision guns. After all, being able to shoot from a distance is very beneficial to the survival of the infiltration troops. Being able to knock down a cavalryman or officer with a single shot is obviously also useful for reducing the pressure in a head-to-head battle.

A few days ago, at the summary meeting, the Intelligence Department pointed out that there must be a big battle within a month, and whether the attackers were pirates or Ming troops, the traversers would face as many as two or three thousand enemy troops coming to encircle and suppress them. If it is a Ming army, it may continue to reinforce on the mainland. It is estimated that if the Ming army cannot be dealt a major blow in a single battle and a part of it is encircled and annihilated, the encirclement and suppression will last for a month or two. As a result, the burden on the Ministry of Industry has suddenly increased. Not only do you have to load 50 guns a day, but you also need to stock up on ammunition for the coming fierce battle. The metallurgical sector is not only making steel, but also copper and lead on a large scale, and is already beginning to produce mini and round iron cannonballs on a large scale with casting molds. It can produce more than 3,000 rounds of mini bullets and 250 rounds of round rounds per day. Coupled with the ammunition already in reserve, it is not a problem to cope with a vicious battle that lasts for several days and fires 30~40 rounds per day.

Artillery. The foundry has already delivered 9 8-pounder smoothbore guns, and it is no longer a matter to cast such smoothbore guns after getting acquainted with the process. The manufacture of breech guns is not very skilled in the processing of the tail bolt at the beginning, and it takes 3 days for a qualified bolt. Zuihou finished only 2 cannons in one week. However, after a collective analysis and study, the mechanical group improved the process. After the steel plate is cut, there is no rush to weld it immediately. It should be placed on the pedal grinder to polish the end face and weld the ladder first. It is then welded with a frame made of local granite slabs. Six 70mm Armstrong guns have now been completed. A 12-pound mountain grenade is much simpler, only if there is enough pig iron to deliver it at the factory rate of one per day. Now 12 pounds of mountain grenades have been handed over to 14 doors.

With the increase in the number of manufactured cannons, the mechanical group has basically figured out the manufacturing process of each type of artillery, the required man-hours and the size of various parts, designed and manufactured a variety of special molds and tooling for the production of artillery, with the help of a large number of measuring tools brought, the mechanical department quickly reduced the tolerance to a minimum, formulated the manufacturing standards of various types of artillery, and began to standardize manufacturing. This will make each cannon exactly the same as its counterparts.

With standardized manufacturing, it means that the performance of each gun of the same type is close. Each batch of artillery manufactured by the Traverser is subjected to a special test firing by an artillery team in order to obtain its firing parameters - the amount of charge and the muzzle height are determined according to the type of ammunition used, the distance to the target. If necessary, the artillery team will also try the very dangerous Shiyan with a maximum safe rate of fire, barrel life and maximum charge. to determine the potential capabilities of its artillery.

The results of artillery tests and calculations are then compiled into a gun table. As long as there are the above four parameters on the gun table. Manufactured into a book in such a way that the artillerymen can quickly consult it. You can even do without words. All you need is graphics (bullets) and numbers.

If these things were to be done entirely by the gunner, then the gunner would need to be familiar not only with the gun itself, but also with mathematics, geometry and even algebra, so the early gunners had to be half-mathematicians in addition to gunsmiths. This is the origin of the so-called "artillery needs high-tech personnel". But this is not inevitable, but the result of backward ideas. With such standardizedly manufactured artillery and gun watches, artillery and Ben do not need to be of high quality, as long as they can recognize the numbers and graphics, and at most they can read a few hundred words. This greatly reduces the difficulty of artillery training. Theoretically, illiteracy is also possible - which is very appropriate for the social environment that the traveler faces.

As a time-traveler, he not only has mastered the modern technology of later generations, but also has the advanced ideas that have been condensed by human society for hundreds of years. Sometimes this idea works more than technology.
