Can shells be universal if the caliber is the same? Of course the answer is no.
Take the most common rifle for example. The 7.62mm caliber was once the standard for the caliber of the intermediate power rifle chosen by the East and the West. So, are the bullets of both sides universal? Of course not universal. The bullet casings of the Soviets were 39mm long, and the West
It is 33 mm long and has different lengths, so of course it cannot be loaded. The 33 mm length bullet in the West was later considered unqualified, so it was quickly eliminated. The Americans began to vigorously promote 5.56 mm caliber bullets.
Leading the trend of miniaturization, the Soviet Union created 5.45 mm, and the Eastern Powers were established 5.8 mm. At this time, someone began to say that it was ulterior motives to do this. On the battlefield, if you pick up the West
The 5.56mm bullet can be loaded into a gun for temporary use, which is better than not having a bullet.
They can also give specific examples: the West's 5.56mm bullets, the shell length is 45mm, the Eastern power's 5.8mm bullets, the shell length is 42mm, putting the two bullets together, the total length is 57mm, the same height
, Therefore, it can be loaded into the magazine and fired it, without affecting the firing needle to trigger the bottom fire. This is simply talking nonsense.
It is definitely not possible to be universal if the bullet is the same as the full length. It also needs to consider the state of the bullet in the barrel. These two bullets are bottle-shaped shells. This kind of bullet is generally positioned with oblique shoulders in the barrel, that is, bottles.
The oblique shoulder heights of the two bullets are quite different, so the 5.56mm bullet is forced into the chamber of the 5.8mm rifle, and the oblique shoulders are pressed against the inclined surface of the barrel of the gun, and the rear of the bullet must be exposed.
For a period of time, in this case, the bolt cannot be turned off at all, let alone fire it.
Moreover, for another reason, the casing diameters of these two bullets are different. The maximum diameter of the 5.8mm rifle cartridge is 10.40mm, and the maximum diameter of the 5.56mm rifle cartridge is 9.58mm, which is nearly 1 mm. In this case, the barrel of the gun
It is impossible to hold your breath at all, and it is impossible to guarantee that the gas after launch will not leak backwards, so it cannot be universal at all.
Small bullets cannot be universal, let alone shells.
So, there is also the same saying: the Soviet howitzer is 152mm caliber and the West is 155mm caliber, so at critical moments, the West can use the Soviet grenades directly, which is nonsense.
By the same token, the shells of the 125mm tank guns of the Eastern powers and the 125mm tank guns of the Soviets are naturally not universal. Except for those outsiders, those experts should be able to know clearly.
Qin Zhenhua was very surprised, how could Berg ask himself such a question?
Of course, Qin Zhenhua could understand it from the other party's standpoint. After Lao Ba really brought the T-80UD tank back, he found that the power was not as powerful as that of the tanks of the Eastern Powers. Their inner aggrievances are conceivable
However, a large amount of funds have been given to Ermao. If it is not continued, the initial investment will have to be wasted, so it can only be to break the teeth and continue the project.
They would think of solving many problems themselves, so they decided to move the shells of the Eastern Power in and try them. But they found that the problem could not be solved at all, so they could only come to ask for advice from the Eastern Power.
Remember the URL
"We know that the two ammunitions are not common, but our 125mm shell uses ammunition to dispose of ammunition." Berg said: "So, we don't change the launching medicine, we only change the warheads, we will make your production
Take the warhead over, which should greatly improve the armor-piercing ability of the tank gun."
After Berg said this, Qin Zhenhua became interested. Yes, if this is the case, it would be OK!
I just talked about the problem of ammunition not universal for a long time. Those are all full-load ammunition. When the tank gun developed to a 125mm caliber, the shells were too heavy and the loading hand could not be moved, so I put on an automatic loader for convenience.
Reloading, and then packed ammunition was created.
Whether it is an Eastern power or an old Russian, they use the method of packing ammunition.
Packed ammunition means separating the warhead and the launching medicine into two sections. Of course, for armor-piercing bombs, the hard core of the back of the core is a waste, so a part is included in the back of the bullet holder.
The launching medicine can also increase the charging of tank guns and increase its power.
The main charge is still in the second half, and the first half is not different. At the same time, it is also convenient to change the size. The bullet heads and cores of the same gun fired different armor-piercing shells are all different in length and can still be used.
If he could make changes to Lao Ba, Qin Zhenhua would be really willing to do it, at least he would become famous.
The tanks produced by Ermao were too poor, but as a result, Lao Ba used ammunition produced by the Eastern Powers. If this matter was spread, would Ermao still have the face? Qin Zhenhua was willing to do such a thing.
Made.
Moreover, this is different from tank guns. Qin Zhenhua refused to match the T-80UD tank with tank guns produced by the first factory. In addition to gamble, it also aims to delay the T-80UD equipment process. However, the shells are different.
, shells are consumables.
Exporting gun barrels is a one-time transaction, but shells can continuously create benefits, so now there is no possibility of rejection.
So, under the attention of all the Pakistani staff, Qin Zhenhua pretended to be contemplative, and after a while, he finally nodded: "Okay, we can help because of the position of our good friends. There will be a lot of things here.
Problem, if we change the ammunition, it means that the ballistics of the shells will change, which means that the fire control system needs to be adjusted. This is a big project."
As soon as these words were said, the people of Bazhong were happy. This time, they came here and reached one agreement after another, which was very beneficial to the Pakistani tank troops. As for the adjustment of the fire control system, it was very good.
They are not afraid of trouble. As long as they can increase their power, they are of course acceptable.
"But, have you done the experiment yourself?" Qin Zhenhua suddenly thought of something and continued to ask.
Lao Ba himself had ammunition imported from the Eastern Powers, so when they found that Ermao's tank gun was insufficient, they should use the Eastern Powers shells and stuff them in and test them.
When they heard Qin Zhenhua's question, they were stunned. Then, someone finally said, "We have conducted a test, but we found that we couldn't stuff it in."
