Chapter 119: It's dark

Actually, it is first decided from the bullet.

Current submachine guns use pistol bullets, why not use rifle bullets directly?

This is because traditional rifle bullets are too powerful when used in automatic rifles, and cannot effectively control the bounce and recoil impact of the gun during fully automatic shooting.

Think about using the current full-power rifle bullets, which can only be used for machine guns. The recoil is not what ordinary infantry can withstand, and at the same time, it is impossible to equip them in the infantry squad. It is too heavy!

Therefore, current submachine guns can only use pistol bullets, which have low recoil and are convenient for continuous firing. However, pistol bullets are not powerful at medium and long distances. The effective control distance of submachine guns is about 150 meters.

In this way, there is a problem, and according to the experience of World War I, the rifle combat range is shortened, and most of them fire within 400 meters. The traditional bolt-action rifle, with a range of one kilometer, is too far to be used by snipers. If everyone uses it like this, it would be too wasteful.

So, we need to study a new ammunition!

Historically, until 1934, Germany began to research and develop short cartridge rifle ammunition, in order to balance the power and control shooting accuracy during continuous shooting. This type of short cartridge ammunition is called an intermediate-power type bullet.

It was not until 1941 that Germany successfully developed and began to produce 7.92×33 mm rifle ammunition. The length of the cartridge case was reduced from 57 mm of the original 7.92×57 mm standard rifle ammunition to 33 mm, and the charge was reduced from about 3 grams to about 1.6 grams. .

It can be found that the study of bullets is even longer! There must be many considerations and trade-offs! And now, it's just the beginning of research!

So, at this time, you can add new ideas, small caliber!

At present, the development of intermediate-power bullets in various countries is based on the original caliber. Maybe it is to unify the caliber, which is beneficial to the manufacture of barrels?

And Cyrek knows that, in fact, reducing the caliber is more beneficial. One of the important reasons is that after reducing the caliber, reducing the weight of the bullets allows the individual to carry more bullets!

can be seen from the trend of later generations!

Therefore, in the following, Cyric made some explanations on the mid-power bullets, encouraged Irma to study a new small-caliber series, and gave several options for Irma to compare and choose from.

This matter, don’t worry! Anyway, there are still several years before the war, and now, as long as the submachine gun is produced, it is the most powerful individual weapon of this era!

How powerful is the submachine gun? Just look at the Treaty of Versailles. In World War I, Britain and France were very scared of the German MP18 submachine gun in the trench battle. Is the speed of fire of the bolting rifle comparable to that of the submachine gun? Therefore, they simply stipulated that the Germans must not develop new submachine guns!

Of course the Germans did not listen to the Versailles treaty, so they developed this new submachine gun!

At least, it has been fine in the past few years! The choice of small-caliber medium-power rifle bullets must be careful!

It was already dark when he came out of Irma, and Cyric was driving on the road in a car.

Ahead, Graf was driving intently.

As a national car, the Beetle is very suitable. It meets the needs of a family and is relatively cheap. However, if you use a car as the chief, it is not enough. There are only two doors, the chief sitting in the back, and getting on and off the car. Very troublesome, and the rear-mounted engine, the noise is even louder.

Cyric was riding in a BMW 325 newly built by BMW.

This is not the later car, this is a pure off-road vehicle!

In addition to various military armored vehicles, the army has also launched a military vehicle development plan in three specifications of light, medium, and heavy. Among them, the task of developing half-ton light off-road vehicles falls on Honamog, BMW, and Stoewer three German civilian vehicle factories.

After all, various civilian vehicles cannot undertake military tasks, and their off-road capabilities cannot meet the standard.

In the history of later generations, this plan was developed through several years of concentrated development by the best German designers at the time. In 1936, the first prototype R180 produced by Stoewer was officially launched and was named the Einheits-PKW series.

Since no German vehicle company has enough scale to undertake large-scale military vehicle orders alone, this has also led to the production of Einheits-PKW by other manufacturers. Among them, the model produced by Stoewer is R180 and its upgraded version R200; Hanomag's The product is called 20B; the one produced by BMW becomes BMW325.

And now ~www.novelhall.com~ history has undergone a small change, because BMW hired a large number of engineers and joined the R&D team during the last time it went to the UK to sweep the goods. Therefore, BMW took the lead in completing the development , Passed the military acceptance.

As in history, this BMW 325 uses an advanced H-shaped steel chassis, front engine, five-speed manual transmission, full-time four-wheel drive system, three front, middle and rear differential locks, and four-wheel double wishbones independent Suspension, and the most sci-fi four-wheel steering, etc.

In addition, in order to ensure that the oil can have sufficient oil pressure in any environment, the car also uses an OHV bottom camshaft and a dry oil pan design.

How advanced are these technologies? You must know that the gearboxes of ordinary cars were only 3 speeds, even the domestic Poussin in the 1990s was still 4 speeds!

The advanced equipment was given to the First Armored Division first, and Cyric unceremoniously asked for one as his own means of transportation.

The brain has been running at a high speed, and Cyric has considered too much for this country.

The historical knowledge of later generations is quite rich. It was summed up by many people. Now, one by one, Cyric alone does it, just like countless concurrent threads. How powerful is the CPU to handle it?

Cyric was tired, leaning on the back seat, Cyric closed his eyes.

Ahead, Graf looked at the road very seriously, two big lights illuminating the dark street.

Suddenly, two bright lights appeared on the side street! These two lights shined directly into the cab!

Cyric behind    suddenly opened his eyes. In Germany, he wants to trouble himself? Humph! It's just looking for death!

"Boom!" At this moment, the car on the side had already slammed into it!
