As the 75-mm breech-loading rifled gun fired, Lin Ziran and a large number of other senior generals of the Sixth Division also used binoculars to observe the shell landing point in front of them.

A few seconds later, I saw a cloud of white smoke rising from a low hill in front of me, only a few tens of meters high.

According to the observations of the artillery observers, at least 20 artillery pieces were deployed on any hill, and many of them were 9-pound field guns and 18-pound howitzers.

It can be said that it is the largest artillery position of the county defense army in front of the city, and the other two artillery positions have only more than ten artillery pieces, and they are mainly five-pound field guns.

The enemy's three artillery positions were the most of this threat, because this was the reason why the experimental breech-loading rifled guns were the first to shell this place.

It is a pity that this shell did not fall exactly in the middle of the enemy's artillery position, but deviated.

However, to carry out artillery bombardment at such a long distance, without professional sighting equipment, relying only on the experience of the members of the artillery crew and the manual calculation of the firing elements, it is quite good to be able to hit the first shell within a few tens of meters in front of the enemy's position.

Therefore, Lin Ziran and the others were not dissatisfied with the deviation of this shell at all, but they were all smiling.

Because this is a long-distance shelling of more than 3,500 meters, although the first shot did not hit, but looking at the landing point of this shell, it is almost the same.

Next, you only need to shoot a few more shells to get a more accurate shot of Zhuyuan, and then the follow-up fight will be more accurate.

Sure enough, after the first shell was off, one of the artillery sergeants who commanded the test reloading turned his head and talked in a low voice with several engineers from the Aoyama Machinery Factory, while calculating with pen and paper.

After all, this gun has not undergone too many tests, and a lot of the data is inaccurate, otherwise, it can be calculated directly according to the design parameters.

After some calculations, this is the readjustment of the height of the gun mount, and after letting an experienced sergeant and veteran gun commander take aim, this is the fire again.

And this time the shells fell directly on the enemy's artillery positions.

Looking at the smoke and dust raised on the enemy artillery position on the opposite side, Lin Ziran continued to observe with a telescope and said, "This power is good!" ”

Kong Deyi on the side also said: "Yes, although the caliber of this 75 mm is a little smaller, it is not even as good as the caliber of the five-pound artillery, but because of the cylindrical projectile body used, the charge is extremely large, and in terms of explosion power alone, it will not be much worse than our nine-pound field guns!" ”

Several other officers also nodded in unison, in the past, they were actually a little worried about the caliber of 75 mm, thinking that the caliber of this thing was too small and the power would not be enough.

But now that they saw a shell fall in the middle of the enemy's artillery position and kill and wound a large area of the enemy, they all showed a satisfied expression.

It is estimated that after today, no one will say that the 75-mm rear-loading gun is not powerful enough.

But even so, Kong Deyi still suggested to Lin Ziran in a low voice: "My lord, although the power of this 75 mm caliber rear loading gun is not weak, but in the final analysis, the caliber is still a little smaller, and it is best to have a large-caliber gun of more than 100 mm or 120 mm, and it is even worse if there is a 150 mm rear loading gun." ”

Lin Ziran smiled: "I don't need you to say it, this official has already instructed the Qingshan Factory to study a larger caliber of rear-loading guns, 100 mm and 120 mm and even 150 mm rear-loading guns, the basic design has been completed, and it is almost time to make a sample gun!" ”

"However, larger calibers also have higher requirements for manufacturing capacity, and it is estimated that it will not be possible to do it for a while and a half, so don't expect it in a short time, this can produce a few more 75mm rear-loading guns, and it will be enough in a short time!"

Lin Ziran actually agreed with Kong Deyi's statement that the caliber of the rear-loading gun is larger and larger, and the longer the firing range, the better.

It's just that the technical ability of the Qingshan Machinery Factory is limited, and it is so difficult to build a 75-mm rear-loading gun, and it is actually very difficult to build a larger-caliber rear-loading field gun.

Of course, this kind of difficulty refers to the long-barreled cannon, if it is only a short-barreled howitzer, then the difficulty is smaller, several large-caliber guns designed and completed by the Qingshan Machinery Factory, in addition to the 100 mm field guns, in fact, the 120 mm and 150 mm are short-barreled howitzers.

After all, it was impossible for the Sixth Division to rely only on 75-mm rear-loading artillery to defeat the world.

Seventy-five millimeters, this caliber is definitely a small caliber for the contemporary Daheng feudal town troops, even if it is a light mortar that belongs to the close support artillery, the Daheng feudal towns will not use such a small caliber.

But the current Qingshan rear-loading gun of the Sixth Division is only 75 mm caliber!

In a country like Daheng where the terrain is flat, the traffic is good, and the service horses are very good, and there are many countries, the development of artillery is bound to be towards the road of large caliber and long barrels.

Therefore, although the current technology is not yet at home, the basic design of the Aoyama Machinery Factory has been completed early, and the next thing to do is how to produce it.

After all, the design principle of the steel rifled rear-loading gun is the same, the barrel material is the same, the bolt structure is the same, the shell system is also the same, and the subsequent large-caliber models only need to be simply enlarged.

So there is no problem in the design, the only problem is how to build it!

Lin Ziran and their side, watching the test rear loading gun accurately hit the enemy, and took advantage of the tail loading and metal fixed ammunition to quickly reset the artillery to directly reload and then continue to shoot, and the rate of fire of the entire artillery bombardment was far more than that of the front loading artillery.

Watching the shells fall on the enemy's artillery positions one by one, the generals of the Sixth Division were all smiling, and if they continued according to this drive, the opponent's artillery positions could be completely wiped out in a few minutes.

But the generals of the 6th Division also obviously underestimated the determination of the other side!

Determination to stay alive!

When the first few shells fell, the artillerymen of the opposing artillery position were horrified, but they were still able to hold their posts.

But when more shells continued to fall, they completely collapsed.

This is still talking about those ordinary artillerymen, and the officers of those artillery are actually more frightened.

Because they found that the shells that hit their artillery positions actually came from more than 3,000 meters away.

How is this possible!

It's absolutely impossible!
