After several days of continuous fighting, more than 200 trial reloading bullets numbered in batches were delivered to the fighters by Mao Drill and others.

The batch numbering is assigned by the Ammunition Department on the basis of nuances in the amount of propellant added, in order to find the most appropriate amount of propellant to be filled.

The amount of ammunition of the original bullets is of no reference value to these reloading bullets.

After all, the propellant of those original bullets is much better than the propellant currently used by the detachment, which is remixed with explosives pulled out of waste shells.

"Our own reloaded bullets succeeded!"

"Hahaha, we won't have to worry about running out of bullets in the future......"

"Minister Mao, give me a few reloading bullets to try, I'm going to open a foreign meat today, hahaha......"

Hundreds of soldiers excitedly surrounded Mao Zuan and a group of ammunition department trainees with small notebooks, shouting and scrambling for these reloaded bullets, hoping that they would be the first to use the bullets that the detachment had successfully reloaded themselves.

But it was clear that this kind of thing would not be the turn of ordinary fighters who had never fired a few bullets in their lives.

These bullets were all distributed to the sharpshooters specially trained by the detachment.

These sharpshooters have shot enough bullets in practice to test fire and have first-hand data that it is obviously the best fit for them to come.

Even if they don't have to shoot to feel it, even if they just hold the bullet in their hand, the marksmen can vaguely distinguish the subtle differences in these similar-looking reloaded bullets.

Bang!

Woo Woo ......

When the sharpshooters were trying to shoot reloading bullets, Mao Drill and other students from the ammunition department were also holding pens and quickly recording in small notebooks, not only recording the feelings of the soldiers shooting and the accuracy of shooting, but also recording the sound of shooting, flames and so on.

All possible data is within the scope of their collection.

"Reloading bullets, and original bullets, there is no comparison between Zhente Niang's......"

After the test firing, Mao Ran complained to Zhang Ran with a bunch of statistical data: "Even the fourth-batch of reloading bullets with the best performance is too far from the original bullet, and the standard target of 100 meters, according to those sharpshooters, no matter how they adjust, is at least two centimeters worse than the accuracy of the original bullet......

Two centimeters, it doesn't look like much.

But when shooting accurately, that is to destroy an enemy, and if you can't destroy the enemy, let the enemy give yourself or your comrades a shot away!

And this is still a 100-meter target!

How much worse would it be if it were 300 meters? What if it was a longer distance?

However, such a question has long been expected by Zhang Ran!

The difference between the original bullet and the reloaded bullet is similar to the difference between the yellow flower girl and the new daughter-in-law who spent the night.

It doesn't seem to have changed, but in fact, it's changed a lot - can the original and the opened one be the same?

"How much room for improvement?" Zhang Ran asked.

"We try our best to improve, but the fourth batch of reloaded bullets is already the best we can achieve so far, and it is estimated that even if we try harder, the effect will not be much better......"

Mao Diamond smiled bitterly: "I feel that the reason why the reloaded bullet is so much worse than the original bullet is not just that the charge is not accurate enough, or that our propellant is not as simple as the original propellant - this gap is simply all-round, such as the degree of wear and tear of the cartridge case, such as the impact of the subtle deformation of the cartridge case, etc...... I'm afraid these things can't be done by our Ammunition Department with more efforts and improvements! ”

"I understand, I know all of this!"

Zhang Ran patted Mao Diamond's shoulder and smiled: "Just try your best, improve as much as you can, just do the best you can do, don't be too demanding-whether the reloading bullet is good or not, but it's better than nothing, isn't it?" Even if we go to the battlefield and shoot birds indiscriminately and rely on blindness, it's better than we don't even have blind bullets, right? ”

"That's right!"

Hearing this, Mao Drill was finally relieved from the unsatisfactory effect of the test firing of the reloading bullets, and said with a smile: "Then we will improve on the basis of the fourth batch of reloading bullets, and after determining that there is no room for improvement, we will carry out mass production - but captain, once it is mass-produced, our ammunition department will have to recruit a large number of people!" ”

There are a lot of trainees, but they are more engaged in the development and testing of ammunition than they are used as workers.

It's okay to reload a small batch of ammunition for them, but if they are reloaded on a large scale and used as workers on the production line all the time, then it will really be an anti-aircraft gun to fight mosquitoes, and it will be overkill!

Not to mention, the propellant of the bullet cannot be directly filled with the powder of the finished drug, but must be tableted, granulated, etc. before it can be used as a propellant......

Even if you want to treat the students as workers, it's still not enough!

"Especially the gunpowder tablet side is too manpower-consuming!"

Mao Drill said with a headache: "I estimate that ten people reload bullets, and twenty of them are enough to press the tablet - if there is any tablet press, it will be good!" ”

"Tablet presses?"

Hearing this, Zhang Ran remembered the jokes about the military industry of the Eighth Route Army in history, and couldn't help but hehe: "The tablet press is simple - you go and call me the stonemason Lao Zheng, and I will ask him to use stones to make a tablet press for you!" ”

"What?"

Hearing this, Mao Diamond said with a look on his face, "Stone tablet press? I've never seen it......"

"Minister Mao, you seem to have seen a fully automated tablet press - stop talking nonsense, go and call Lao Lin!" Zhang Ran's spirit was vivid.

Lao Lin listened to Zhang Ran's thoughts, and suddenly said: "Isn't it just a stone mill, what's so difficult about this-I'll let people go to the mountain to find me two stones to come down, and I'll hit them right away!" ”

Mao Drill also shouted on the side: "This stone mill is broken, where can it be used as a tablet press!" ”

"Can you all listen to me first?"

Zhang Ran slapped the table and took out the majesty of the top leader of the detachment to shut up the two, and then Zhizhu explained to the two.

The working principle of the stone mill is to create toothed stone marks on the junction surface of the upper and lower stones of the stone mill, and grind the grain put into the stone mill during rotation.

"I mean, the saw marks on this junction don't be, it's all flat!"

Zhang Ran carefully instructed Lao Lin, in addition to the fact that the junction surface is a plane, it is necessary not to let the stone mill bite together, but to leave a certain gap on the central axis, so that it is convenient for the pills to be rolled out to maintain a relatively consistent thickness.

"In that case, every time you finish crushing the tablets, you have to separate the upper and lower grinding discs to take out the tablets, and then you can crush the next batch of pills - this is not right, captain, your method, it is better for Minister Mao to use a rolling pin to roll out the tablets directly!"

Lao Lin's head shook like a rattle, and he said with an expression that I know better than you in the stonemason major: "The reason why this stone mill adds grain from the middle of the grinding eye, and the ground grain naturally comes out when the grinding is pushed, it is all the credit of the zigzag marks that have been chiseled, but it is not like the captain you take for granted, as long as you add food, it will come out as a matter of course......

Zhang Ran was very unhappy in his heart, staring at Lao Lin Xin stupidly and said, Okay, you old Lin, why is it not good to learn, but you don't want to save face for the leaders at all by learning these calves?

actually said that the idea of this leader is taken for granted - do you still want to mess with you!

But it's not happy, but Zhang Ran has to admit that his thoughts are a bit taken for granted.

He had seen the stone grinding thing when he was a child, and he knew that as soon as the grain was added from the grinding hole, the grain would naturally grind out with the rotation of the grinding disc, where did he think that there were so many twists and turns?

If according to Lao Zheng Lin's statement, if the pills are completely flat, even if they are crushed, they will not run out, and they have to separate the stone mill and pick it from the inside, which is indeed a bit of a fart after taking off their pants, which is not lighter than the ammunition department using a rolling pin to roll out the pills.

Just when Zhang Ran was thinking about how to find the bottom of the stairs for his ignorance, Lao Lin spoke: "Captain, you said that this pill is not as smooth as the dumpling skin, but it is barely in the middle of the pill?" ”

"Okay!"

Without waiting for Zhang Ran to answer, Mao Ran jumped up first and said: "As long as the thickness of the pills is not too bad, it is convenient for us to cut the pieces - anyway, we don't really make dumplings......"

"Then I have a way!"

Lao Lin immediately straightened his chest and said that he had covered himself!

Zhang Ran immediately forgot about the old face and the dull things to the clouds, and with a look of Lao Lin, you solve problems for the leader, and the leader said with a very relieved expression: "Lao Lin, you do a good job, as long as you can really help Minister Mao get this stone mill tablet press out, the captain will give you credit!" ”

"Hey, captain, give me three days, I promise to get it out!"

As soon as he heard the credit, Lao Lin smiled and said, "But why does this stone mill tablet press sound so awkward?" I think it's more pleasant to call it a stone mill mill......"

"Whatever you want!"

Zhang Ran waved his hand very open-mindedly and said: "As long as it can be made, Lao Lin, your work, you say that it is a sheet grinder, that is a piece grinder, I have no opinion......"

Thinking that if Lao Lin really got the tablet grinder, the efficiency of reloading bullets would be improved a lot, Zhang Ran had a big heart, and he only hated that the conditions of the current detachment were too simple, otherwise he would have to make a few braised vegetables and drink a few glasses of soju.

Before he could sit down, Han Jinshan came and brought a glass bottle.

Glass was discovered very early, and it is actually not uncommon in China.

In addition, the detachment can use it, so they have been paying attention to collecting these things for a while, so they have found a lot of them.

What is really lacking is special glassware, such as measuring cups for experiments, beakers and test tubes.

Now the Ministry of Chemical Industry, Han Jinshan's detachment hospital, is using this kind of glass bottle to do various experiments, although it is not as easy as professional glassware, but it is better than using clay pots and the like all the time.

After all, it's glass, and no matter how easy it is to use, it's at least transparent, so it's easy to observe, isn't it? It is also less likely to react with other substances than clay pots.

The glass bottle was opened, and a strong aroma of wine wafted out.

Zhang Ran didn't think that he and Han Jinshan had a good heart, as soon as he wanted to drink, people sent wine to his door.

"Alcohol?"

Zhang Ran sniffed and asked.

Han Jinshan nodded fiercely and said excitedly: "After testing, it has reached the standard of medical grade, and in the future, we don't have to worry about the soldiers getting infected because of insufficient wound cleaning!" ”
