The season has entered autumn, but it is not yet the time when the leaves turn yellow and a large number of leaves fall with the wind.
Located in the south of Chang'an, close to the Qinling Mountains, there is a small military camp on the edge of the mountain range.
The existence of the military camp is to block the perimeter, looking at those perfect blockade lines, and then looking at the pass into the Qinling Mountains, it is not difficult to imagine that there will be any facilities in it that do not want to leak secrets.
"Your Majesty."
Zhang Shi held a rifle in his hand and introduced: "This rifle is an improvement on the basis of Type 12, the length of the gun body has not changed, the weight has been increased by one catty, and the caliber has been reduced to fourteen millimeters.
Its barrel was changed to a rifled and smoothbore version, and after testing, it was more accurate and had an increased range. ” To put it bluntly, it was a rifled gun, and in terms of level, it should have reached the level of the middle of the fifteenth century.
"The barrel is both spiral and straight."
Ma Zihuan is an expert, and introduced in detail what the results of the change in barrel structure will be, and later commented: "After repeated tests, the spiral barrel is obviously superior to the straight barrel. ” Although Liu Yan has passed all these years, he has not completely abandoned his attempt at guns.
A spiral-shaped gun management post is of course better than a straight barrel.
When the spiral-shaped barrel fires the projectile, the long lead pellet can be rotated, and the flight is stable after discharge, which improves the shooting accuracy and increases the firing range.
There is a machine tool next to everyone, which naturally cannot be driven by electricity, but it uses animal power.
The most conspicuous thing about the machine is the drill stick, which itself is a spiral style, and when drilling, there are also spiral lines left in the barrel.
In terms of the current level of science and technology, such a machine should be the best use of hydraulic power, but it is not easy to find the right river first, the machine tool has been successfully developed for less than half a year, and the suitable location has not been found for the time being, and it is temporarily set up as an animal power style in Qinling.
Two or three years ago, there were craftsmen who were able to build rifled barrels by hand, but the yield was not high, and there were too few craftsmen who could do this, and it didn't matter how low the output was in terms of just becoming a "toy" for a few people, but it was too few for a firearm that needed to be mounted.
Liu Yan only put forward an idea, Shaofu used the best efforts to study and test, and it took three years to develop the machine tool.
The new machine tool in this factory in Qinling, it is currently a unique existence, after trying to drill up to five barrels a day, the yield rate is four barrels, it can be said that the yield rate is already a little frightening.
"If it is changed to a hydraulic drive, the efficiency can be increased by about two times."
Ma Zihuan already knows what dynamics and what kind of efficiency a machine can play, which is generally the driving decision: "It takes half a month to make the rifled barrel by hand, and Chen deeply feels the gap between manpower and machinery. ” There is only one new machine tool, but it does not mean that there is only one machine tool in the country, such as the machine tool used to build an ordinary barrel before, and those machine tools are divided into two types: animal power and water power.
Some of the previous scientific research achievements are the basis for ensuring upgrading, and any technology is indeed becoming more advanced from generation to generation, unless something miracle happens, otherwise it is impossible to use it to throw stones at the last moment, and the next moment it is holding a Gauss firearm and firing it in the "Xiu Xiu Xiu".
Accumulation is an inevitable process for science and technology, and that process is actually to understand the elements, and then extend various sciences, from a variety of scientific research results to combine a product.
"This rifle is named the Twelve-Style."
Liu Yan took the rifle, and in general it did not change much, comparing a posture of holding a gun and shooting: "The longest range is 920 meters" "Back to Your Majesty, yes."
Zhang Shi said reservedly: "The accurate shooting distance reaches 280 meters. ” Liu Yan remembered that the appearance of rifled guns changed the way of shooting in platoons and platoons, and the soldiers holding rifled guns were no longer in a tight formation, they were formed into a straggler array to take advantage of the firing range, and they were no longer close to each other to shoot a salvo, but a way of shooting back after repeating the shot until the opponent could shoot at the distance from which they could shoot themselves.
Liu Yan, the first person to make a soldier with a rifled gun a sniper, has forgotten that after the first one did that, the war in the era of firearms has entered a new mode, and after the commander has been sniped repeatedly, there is no commander who is stupid to look for death.
"Your Majesty."
Zhang Shi asked flatteringly: "But I want the minister to bring gunpowder."
Liu Yan really wanted to shoot in person, came to the shooting range to skillfully load, and after finishing, he made a standard posture with a gun and aimed at the target 100 meters away.
When he pulled the trigger, his body felt the recoil, and there was a "pop" sound in his ears.
In the distance, a set up target made a "poof" when the projectile hit, and a puff of dust and smoke was quickly blown away by the wind.
Someone brought the target over, and the hole in the center of the target ring of the gun showed that Liu Yan hit it very accurately, and it also proved that this 12-style change could be used as a sniper firearm.
"Try one hundred and fifty meters."
After Liu Yan cleaned up the chamber, he was doing loading work again: "The butt of this gun should probably be changed and slightly lengthened by about three centimeters."
The person holding the notebook next to him immediately took notes.
What's the use of a gun just making a three-centimeter change, that's a question that only people who don't know how to do it.
Not to mention a firearm, even if it's a sword, the slightest change will produce a different feel.
The length or length of the firearm, and even the weight of the firearm, to achieve the most reasonable design, the more powerful it can be exerted.
The feeling of holding a gun is very important for shooters, even if it is just a little more comfortable when holding a gun, the difference in thoughts and feelings, and the more reasonable posture, every shot can be more accurate.
Otherwise, there is no need to distinguish between standard equipment and customized equipment, like modern competition, who will use standard equipment, all of which cost a lot of money to customize and build.
After Liu Yan finished loading, he once again became the standard gun holding posture, but he maintained the aiming action for a longer time than the previous time, not only aiming at three points and one line, but also observing the plants around the gun target.
Whether a firearm is accurate or not, not only considering the firearm itself, but also testing the gun holder, at least should understand that the wind direction and wind force are also one of the factors whether it can be accurate.
Liu Yan observed the plants around the wall to determine the wind direction and strength, and when aiming, he adjusted the aiming device, so that the three points and one line changed.
The adjustment of firearm parts is a very professional move, such as aiming at a 100-meter target and aiming at a 200-meter target, the aiming device must be slightly adjusted, and the difference in wind power also needs to be adjusted accordingly, otherwise it will be a standard shooting target of 100 meters, but the same three-point and one-line shooting target of 200 meters is much more off.
Although the standard device of the 12-type modification is an adjustable mode, there is no professional scale, and the user still needs to have sufficient knowledge and common sense proficiency.
Don't look at it as just adding a scale, but just such a small part, with the current level of technology, the time required is definitely not short.
With a blow, Liu Yan's body swung backwards, and his brows furrowed after he shot.

After the target was lifted, the position of the hit was within the seven rings, and although Liu Yan frowned just now, he did not hesitate to praise the rifle.
Whether the shot is accurate or not is not only a problem of the quality of the firearm, but also the reason of the shooter, Liu Yan will not use his own mistakes to deny the excellence of the gun.
Liu Yan is obviously not a person who gives up after experiencing one unsuccessful experience, and then shoots twice, and only stopped the test firing after hitting the ten rings.
There are professional test shooters at the shooting range, and they have been waiting by the side, seeing that Liu Yan can hit the ten rings with just three shots, whether he is pretending to be or not, he shows an expression of admiration.
The three test firings were followed by test firing in turn, 50 meters, 100 meters, 150 meters, 200 meters, 250 meters, 300 meters, the farther away the target, the lower the accuracy, a total of 30 shots, the best result is to hit the three rings of the target at 300 meters, and it is a lot of luck to be able to hit.
After the test firing is completed, the test firing personnel will evaluate the firearm in a professional direction, and the recording personnel will record them one by one, all in an effort to do the best.
The evaluation and recording were carried out there, and the military generals who came with it lined up for the test firing, which seemed to be having a good time.
"It's excellent."
With a smile on his face, Liu Yan said to the generals who had watched the whole process and shot himself: "Excellent shooters should be selected to use this weapon specifically." ” "Your Majesty is innocent."
Huan Wen had just tested firing a target of 50 to 200 meters, and although he had not hit the Ten Rings, the results were not too bad: "It is a weapon that can kill the enemy in the midst of thousands of troops on the battlefield. ” Ran Min played with firearms a lot.
He just tried firing a few times, and the worst result within 200 meters was also to hit the eight rings: "I thought the flintlock pistol was powerful enough, but I didn't expect that just by changing the barrel, the accuracy would be so terrifying." ” The advent of firearms will inevitably change the way of warfare, the simplest is that the value of force will be reduced, a master who has been training for decades will die if he is shot, a person who does not know any fighting skills will die if he is shot, and the value of immersing oneself in practicing fighting skills will become a matter of little significance.
Xu Zheng saw the bitterness on Ran Min's face, and he didn't want to comfort him at all.
For example, with the change of the form of war, pure bravery is no longer useful, and the value can be reflected in the art of command and various experiences.
To put it simply, the history of relying on simple martial arts to obtain meritorious deeds will soon pass, and those who do not keep up with the pace of the new era are destined to be eliminated.
"Your Majesty."
Zhang Shicai didn't care what kind of mood the military generals were in, and asked Liu Yan: "Do you want to visit the next place?"
Liu Yan could guess that the Shaofu Ordnance Research and Development Department must have some new achievements before Zhang Shi could ask something like that.
The group left this rifle range and did not go far to another range.
It is also a shooting range, but it is necessary to change the location, just because the shooting range is also different, for example, rifles and artillery are also shooting, and the firing distance and the degree of impact are two different sides.
Liu Yan originally thought that he would go to the artillery test firing site, but he didn't expect that the place he came over was also a firearms range, so he didn't have time to have any doubts, but his eyes saw a big guy in the test firing position.
It was a multi-barrel device with a base that supported the barrel, and the overall appearance was both strange and hideous.
"You guys got it" Liu Yan would be surprised, it was that guy was infinitely close to the Gatling gun at all, but it was much bigger.
He approached and stroked the hanging bullet chain and asked Zhang Shi: "The bullet has been able to be mass-produced."
The flintlock pistol also needs to be charged and projectile steps, and then evolved into a rear-loading gun.
The advent of cartridge bullets was a revolution in the evolution of firearms, so that rifles no longer needed to be operated separately from gunpowder and projectiles, which should not have appeared until the eighteenth century, and was repeatedly developed and matured, and eventually became the modern bullet style.
The bullets that were packed into chains, they were about four centimeters long, Liu Yan walked to the table next to him, picked up a bullet that was neatly placed, and observed the whole and found that it was completely different from his own requirements, and the shell, primer, propellant and warhead that should be there after disassembly were fully equipped.
"Your Majesty."
Zhang Shi looked embarrassed: "The maximum output can achieve 1,300 rounds per day." ” If one person or one machine can produce 1,300 rounds per day, it will indeed be a very good result, but the key problem is that the relevant institutions of the entire Shaofu can have such efficiency.
"Still improving" Zhang Shi looked at Ma Zihuan as if asking for help: "Keep improving, the master knows more." ” Liu Yan nodded to Zhang Shi expressionlessly and looked at Ma Zihuan.
"Your Majesty, the ministers have figured out the manufacturing process."
Ma Zihuan is full of confidence: "The new machine tool has been successfully developed, as long as special components can be developed, we will be able to increase production." ” If you want to do something, you must have special components, the Han Empire is now completely short of metals, what is needed is to accumulate on the road of science, as long as there is enough perseverance, and then there are diversified talents and sufficient funds, the pace of progress will never stagnate, on the contrary, it will go faster and faster because of the continuous accumulation of basic science.
Regarded by Liu Yan as the big guy of the cannon, it began to shoot under the operation of professional personnel.
There is no such thing as pulling the trigger, it is the operator who keeps shaking it against a handlebar, and each shake is a primer fire on the bullet, and then presents the bursting process of the bullet.
Under the constant "click" movement, the target in the distance was torn to pieces, but the big guy was dumb in less than twenty seconds.
"This is," the professional engineer checked it and reported profusely: "It's stuck." ” Most of the people were stunned just now, knowing that the hideous weapon still had major flaws, on the one hand, they were relieved, and more they felt pity
