"Ah Zhen, this musket is something you improved on the basis of the previous firecracker?" In the study, Ning Zhiyuan asked while caressing the iron pimple in his hand, and the excited look on his face had not completely dissipated.

At this time, the musket that Ning Zhiyuan was holding in his hand was slightly different from before. On the outside of the sheet metal machine, there is an extra piece of iron sheet, which wraps the entire linkage device.

This was specially added by Chi Fei to the craftsman, in order to protect the entire ignition linkage from being damaged by a collision, after all, this part of the machinery is too fragile.

Compared to a real flintlock pistol, this knock-off musket is not only too thick in barrel, but also has a firing mechanism mounted on the outside, which is really a bit rudimentary.

But it's also something that can't be helped.

First of all, the barrel is too thick, and this problem is basically unsolvable.

Because the temperature of the ancient iron-making furnace was insufficient, the iron smelted would correspondingly lack strength.

If you make a thin iron barrel according to modern standard caliber, you may explode as soon as you shoot.

Therefore, it is also a last resort for craftsmen to make the barrel so thick.

Chi Fei is an art student, and the devil knows how to make steel.

It's not something you can learn by looking at materials or videos, it's so technical it's no easier than making a large piece of glass.

Therefore, Chi Fei has given up the idea of letting the craftsmen make the barrel thinner, and just wants not to blow up the bore.

The second is the situation that the ignition linkage device is installed outside, and Chi Fei feels that although it is ugly, it also has an advantage, so it is relatively simple to repair.

Repairs can be carried out by simply disassembling the iron panels. Unlike traditional flintlock guns, the entire gun needs to be taken apart for repair.

Chi Fei is a pragmatist, in his opinion, as long as this first batch of copycat muskets can really be used in actual combat, the rest of the appearance, weight and everything is a small problem.

When the musket can be mass-produced, it is not too late to slowly improve it.

In order to let his father-in-law see the combat ability of the musket, Chi Fei asked Zhang Wu and Su Zihang to practice how to use it in secret.

Although he had already let Ning Yabai and Ning Yafeng know about it, in order to surprise his father-in-law, Chi Fei still waited for Zhang Wu and them to practice for nearly a month before letting them demonstrate in front of their father-in-law.

And the brothers Ning Yabai and Ning Yafeng were also very interested in this musket, and often took advantage of Zhang Wu and their practice to try it several times.

After nearly a month of practice, Zhang Wu and the others were able to complete the entire loading action in only about thirty seconds.

The reason for this speed is that the pool does not use the method of quantitative filling.

The method of dosing is very simple: first weigh the gunpowder of the same weight, and then put the lead bullet and gunpowder into the whole paper bag.

Put lead bullet in the front half of the paper bag, gunpowder in the back half, and tie a thread in the middle to separate lead bullet and gunpowder.

When Zhang Wu and the others were loading, they first used their teeth to bite open the part containing gunpowder, and then poured a little bit of gunpowder into the fire door as a primer.

Then pour all the remaining gunpowder into the barrel and stuff the whole paper bag with lead bullet inside.

Finally, use the pusher to push the paper bag to the end, and the whole filling action is completed.

Since the paper bag itself just plugged inside the barrel, the gunner did not have to worry about lead bullets and gunpowder accidentally pouring out.

When the gunman pulls the sheet metal machine, the flint will produce a spark after impact, igniting the primer on the fire door, and the primer will then ignite the gunpowder in the barrel, so that the explosive air pressure will be generated to spray out the lead bullet and the paper bag in the barrel together, forming a complete shot.

This approach was not thought up by Chi Fei himself, but he saw it when he checked the information and watched the video.

In order to reduce the reload time, most of the armies that used flintlock muskets in the past did this, and Chi Fei just followed the example.

After practicing for so long, Zhang Wu and others have basically mastered some rules of aiming, which has significantly improved their accuracy.

Now they can basically achieve a hit rate of about 40% within 30 steps, that is, they can hit about 4 or 5 shots with 10 shots.

Of course, this so-called hit rate is not always a hit, as long as it can hit the target, it is considered a hit.

And the three muskets they used were the first finished products made by Wu craftsmen.

Since the inner diameter of the barrel is polished by hand, the inside is constantly uneven, so the accuracy will be much worse than that of the drilling machine.

Chi Fei believed that as long as the drilling machine tool could be used for piercing and grinding, the effective range should be able to reach less than 100 steps, which was about the same as an ordinary smoothbore gun.

Now it's just to demonstrate to my father-in-law that I take these three semi-finished products to practice.

After Zhang Wu and others demonstrated target shooting, Mr. Zhang Wenxuan found a reason to leave in advance in order to avoid suspicion.

And Ah Zhi knew that her father would definitely ask her sweetheart about the musket, so she also went back to her room very well-behaved.

At this time, in the study, there were only Ning Zhiyuan, Ning Yabai, Ning Yafeng, father and son, and Chi Fei, a total of four people.

Hearing his father-in-law's question, Chi Fei replied, "Yes, father-in-law." This musket was indeed a modified torch, using the principle of flint striking fire to replace the original ignition rope, which could greatly reduce the firing time.

Compared to ordinary bows and crossbows, muskets have three major advantages.

First, it is simple to use, and ordinary soldiers can basically use it after one to two months of training, and they can become familiar with gunmen for more than half a year.

The second is that as long as the ammunition is sufficient and the stone is replenished in time, it can shoot continuously, and the archer is basically too tired to pull the bowstring as long as he shoots a dozen arrows.

Third, it has strong penetrating ability. Father-in-law, you have just seen that at a distance of thirty paces, the lead bullets fired by this musket can easily pierce armor, which is also something that ordinary bows and crossbows cannot do.

In fact, it has a range of far more than 30 paces, and can penetrate armor even within 100 steps, but its accuracy gets worse with the distance.

But there are pros and cons to everything, and after talking about the pros, I will talk about the disadvantages of this musket.

One is that it cannot be used in the rain. Not to mention rain, even in a relatively humid environment, it can greatly affect the use of the musket.

The simple reason is that the water vapor will cause the gunpowder to become damp and not ignite.

This is the inherent shortcoming of the musket, which is basically unsolvable. So on a rainy day, the musket is a useless burning stick.

The second is that it takes a long time to reload ammunition, which is not as fast as a bow and arrow.

Father-in-law, you also saw just now, every time a buckshot is fired, Zhang Wu and the others need about thirty breaths to reload before they can fire a second shot. This is only after the flint impact is used to replace the ignition rope, otherwise it will be slower.

In order to solve the problem of slow reloading, I deliberately asked Zhang Wu and the three of them to line up.

When the first person shoots, he immediately relinquishes his position in front to the second person, and then goes around to the end of the line to hurry up and reload his ammunition.

Immediately after the second person shoots, repeat the operation and return to the back to continue reloading.

Under this step, which fires in turns and reloads, skilled soldiers in groups of three can basically fire every ten breaths, instantly increasing the original firing frequency by three times.

The third is that the production of muskets is not only expensive, but also takes too long.

The three muskets in your hand are the three muskets that took dozens of craftsmen, including Wu craftsmen, more than half a year to make these three after scrapping more than a dozen barrels.

At this rate, there is no way to mass produce it. This is the biggest problem in the production of muskets.

In order to solve this problem, Wu Craftsman and I are working on a way to build a machine that can produce gun barrels more quickly, and if successful, it should be able to greatly shorten the manufacturing cycle.

That's probably it, I wonder if you have any other questions for my father-in-law? ”
