What happens if a bullet is loaded backwards? How to heat up a bullet gun faster? What happens if you heat up a bullet?

The bottom line is that for the bullet to reach operating temperature In order to get bullets without sagging and the same mass, you need to make 20-30 bullets for rejection, in the case of complex shapes like paradox, a bullet only at 5 or even 6 ten turns out to be ideal.
Does anyone have ways to quickly or autonomously heat bullets? So that the bullet gun itself would heat up, I took it and started making “finish” bullets from the very first casting.
Maybe preheat it in the oven or something?

pcmist 02/23/2016 - 21:00

By the way, yes, I’ll try the electric stove!

Onuris 02.23.2016 - 22:15

I use a 1 kW spiral electric burner from a "Dream" stove for faster heating, and additionally use a gas burner that runs on gas cartridges. The bullet for the Diabolo and Koratkov bullet, after pouring the lead, has to be thrown into the water, otherwise the bullet is very difficult to get out, but on the burner and with gas, it heats up in 20-30 seconds, and the new bullet comes out perfect. A gas cylinder is enough for 80-100 bullets.

What are the signs of lead overheating and what does it mean?

Evgeny_k26 02/24/2016 - 08:17

What if you don't pull out the bullet right away? In theory, it should give its heat to the watering can. I do like this. I hold the first five to ten bullets longer until it turns out without defects

Well, this is understandable, but personally, for absolutely perfect bullets, so that I wouldn’t be ashamed to sell to people, I have to make much more test castings. Especially bullets with a complex profile, such as a paradox. I pour on the balcony, it’s about zero or a small minus. Maybe this has an effect.

Mikha78 02/24/2016 - 09:03

I have lead in the crucible, and the watering can is on a piece of iron 5 mm thick, which in turn is on a gas stove, which is powered by spray cans. I turn them on at the same time. When a frost pattern appears on bullets, this is the first sign of overheating.

By the way, I tried to heat it on a tile - this scheme does not work (((

Overheated lead - the bullets will be brittle. I recently became convinced of this myself.

Bloodsucker 02/24/2016 - 11:28

I heat it in a cast iron stove on a gasoline burner.
After complete melting, I let it sit on the fire for another five minutes, after which I start pouring it into the extra watering can. The first five bullets go back into the cast iron, after which they are working.

or something else?

AzSs 02/24/2016 - 15:40

I heat it with lead, send the first 10 bullets back to the smelter and that’s it.

Sometimes I just put a watering can on the lid of the crucible while it heats the lead.

Good day.
When the ambient air temperature is low, it takes a very long time to reach the mode, and it only flows when the bullet is pressed closely to the crucible nozzle. I moved to the bathroom for the winter.
Sincerely, Alexander.

“When fired, a powder charge of a rifle cartridge weighing 3.25 g burns out in approximately 0.0012 s. When the charge burns, about 3 calories of heat are released and about 3 liters of gases are formed, the temperature of which at the time of the shot is 2400-2900 ° C. The gases, being highly heated, render high pressure(up to 2900 kg/cm2) and eject a bullet from the barrel at a speed of over 800 m/s. The total volume of hot powder gases from the combustion of the powder charge of a rifle cartridge is approximately 1200 times greater in volume than there was gunpowder before the shot."

Lead begins to melt already at 300 degrees... but the bullet flies intact. This means that the temperature of the bullet at the start with the gas initiation temperature (2400-2900°C) is low. Since lead does not melt in the barrel at the start. This is an example for a pump action shotgun. We are simply accustomed to the fact that when it hits a living target, as in the movies, the bullet leaves a burn and the site of impact smokes. These are just special effects. Since the warhead stuck in the metal is intact. This means that she was actually cold at the time of the collision.

It turns out that in flight there is no critical heating sufficient to transition to another state of aggregation, it is not present even at the time of active invasion. Here we should not forget that the bunker is a multilayer laminated resonator. But the main thing is that it is empty! It is important. Since if the resonant barycenter were entirely made of homogeneous material, then we could only talk about the penetration depth. This indirectly confirms the presence of internal emptiness in planets that have completed accretion.

Notice the scar on the side and on the forehead. The difference is colossal. Lateral - invasive. And the frontal one is impact (. That is, the projectile did not hit a local surface, but rather resonated the entire bunker.

We are accustomed to the fact that the density of matter is volume and mass. But since the projectile is cold, and bullets with the same density, in the form as in the photo, according to the logic of things, should not exist in this world, we can conclude that density is the volume and circular frequency of Rayleigh. And mass and temperature have absolutely nothing to do with it.

Actually, the answer to why a cannonball fired head-on from a cannon at a stone bastion rotates madly when falling to the ground is simple (while in flight it is subject to only slight derivation), this means the centripetal component of the cannonball mass turns into a centrifugal one. These forces are orthogonal in meaning. But this means that in one of the orthogonals, the projectile loses mass.

Preliminary conclusion: if the bunker tower rotated, then its thickness would no longer be important for protection. And the correspondence to the moment of complete safety of the tower would begin as ω^(3) bunker per R^(2) bullet.

I didn't shoot at the rotating head of an airplane's propellers. In the “spinner” fairing itself. Not into the impeller, but into the center of the propeller. Since there is no gun or plane. But I am sure that the propeller spinner is the safest part of a fighter in a head-on collision.

I would like to note that Soviet heroes The Red Army soldiers were almost inhumane - harsh, they gave in to “good”, to the fascist bastards. And it’s true that bullets were crowded at Stalingrad!

The topic of liquid propellant mixtures is one of those topics that appears and then disappears again. Discussions about the possibility of using some kind of explosive liquid instead of gunpowder in cartridges and shells often proved fruitless. It quickly came to the conclusion that “nothing is impossible” and the discussion ended there.

It would seem, what else can be added to this topic? It turns out that it is possible, and quite a lot. The list of substances and their mixtures suitable as a liquid propellant is quite large and there are very interesting options. But now we will focus our attention on one long-known substance - hydrogen peroxide.

Hydrogen peroxide is a transparent substance that looks like water. The photo shows 30% peroxide, better known as perhydrol.

Hydrogen peroxide has been widely used and is now used in rocket technology. The famous Aggregat 4, better known as V2, used hydrogen peroxide to drive turbopumps that pumped fuel and oxidizer into the combustion chamber. Hydrogen peroxide is used in the same capacity in many modern rockets. The same substance is also used for mortar launch of missiles, including in underwater launch systems. Also, the German Me-163 jet aircraft used concentrated hydrogen peroxide (T-Stoff) as an oxidizing agent.

Chemists were well aware of the ability of hydrogen peroxide, especially in high concentrations, to decompose instantly, with an explosion and release large quantity water vapor and oxygen heated to high temperatures (the decomposition reaction occurs with the release of heat). 80% hydrogen peroxide produced a vapor-gas mixture with a temperature of about 500 degrees. A liter of such hydrogen peroxide upon decomposition gives different sources from 5000 to 7000 liters of steam gas. For comparison, a kilogram of gunpowder produces 970 liters of gases.

Such properties fully allow hydrogen peroxide to act as a liquid propellant. If the steam gas from the decomposition of hydrogen peroxide is capable of rotating turbines and pushing out ballistic missiles from the launch shaft, then he is even more capable of pushing a bullet or shell out of the barrel. This would provide major benefits. For example, the possibility of significant miniaturization of the cartridge. However, as is well known to any person knowledgeable in firearms, hydrogen peroxide has never been used or even proposed as a propellant. There were reasons for this, of course.

Firstly, hydrogen peroxide, especially concentrated, instantly decomposes explosively upon contact with most metals: iron, copper, lead, zinc, nickel, chromium, manganese. Therefore, any contact with the bullet or cartridge case is impossible. For example, trying to pour hydrogen peroxide into a cartridge case would lead to an explosion. Safe storage of hydrogen peroxide during the birth and most rapid development of cartridge technology was possible only in glass vessels, which posed insurmountable technological barriers.

Secondly, hydrogen peroxide, even in the absence of catalysts, slowly decomposes, turning into water. average speed The decomposition of the substance is about 1% per month, so the shelf life of hermetically sealed hydrogen peroxide solutions does not exceed two years. It was not very convenient for ammunition; they could not be produced and stored for decades, like conventional cartridges.

The use of a new propellant such as hydrogen peroxide would require such major changes in production, storage and use firearms and ammunition for it, that they did not even dare to carry out such experiments.

However, why not try? Several very compelling arguments can be made in favor of hydrogen peroxide, although several unusual properties, to a greater extent military-economic. If the arguments are best considered together with the proposed design of a cartridge with a charge of hydrogen peroxide, so as not to repeat it twice.

First. Hydrogen peroxide (and some mixtures based on it) is a propellant, produced completely without the participation nitric acid, this indispensable reagent for the production of all types of gunpowder and explosives used. In the military economy, mastering the production of at least part of the propellant or explosives without the use of nitric acid means the possibility of increasing the production of ammunition. In addition, as the experience of the same Germany during the Second World War shows, all nitric acid and all ammonium nitrate (in Germany it was used both as an explosive and as a component of artillery gunpowder) cannot be used only for ammunition. Something else needs to be left for Agriculture, because bread is no less important for war than gunpowder and explosives.

And the production of nitrogen compounds is a huge plant, vulnerable to aviation or missile strike. In the photo - Togliattiazot, Russia's largest ammonia producer.

Hydrogen peroxide is produced mainly by electrolysis of concentrated sulfuric acid, and subsequent dissolution of the resulting persulfuric acid in water. From the resulting mixture of sulfuric acid and hydrogen peroxide, 30% hydrogen peroxide (perhydrol) can be obtained by distillation, which can be purified from water using diethyl ether. Sulfuric acid, water and ethyl alcohol (which is used for the production of ether) - these are all the components for the production of hydrogen peroxide. Organizing the production of these components is much simpler than the production of nitric acid or ammonium nitrate.

Concentrated hydrogen peroxide is quite dangerous, but rocket scientists have long developed an explosion-proof normal conditions a mixture consisting of 50% aqueous solution hydrogen peroxide with the addition of 8% ethyl alcohol. It decomposes only with the addition of a catalyst, and gives steam gas more high temperature- up to 800 degrees, with appropriate pressure.

Second. Apparently, loading a cartridge with hydrogen peroxide will require much less than gunpowder. It can be assumed for rough calculations that this substance produces on average 4 times more gases than gunpowder, that is, to obtain the same volume of gases, the volume of hydrogen peroxide is required to be only 25% of the volume of gunpowder. This is a very conservative estimate, since I could not find more accurate data, and the data available in the literature vary greatly. It is better not to get carried away with more accurate calculations and tests.

Let's take the 9x19 Luger cartridge. The internal volume of the cartridge case occupied by gunpowder is 0.57 cubic meters. cm (calculated from geometric dimensions).

25% of this volume will be 0.14 cubic meters. cm. If we shortened the cartridge case to such a volume occupied by the propellant, then the length of the cartridge case would be reduced from 19.1 to 12.6 mm, and the length of the entire cartridge would be reduced from 29.7 to 22.8 mm.

But here it should be noted that with a cartridge diameter of 9 mm, the volume for the propellant charge is 0.14 cubic meters. cm requires a height of only 2.1 mm. And the question arises: do we even need a sleeve here? The bullet length in this cartridge is 15.5 mm. If the bullet is increased in length by 3-4 mm, and a cavity is made on the back side for the propellant charge, then the cartridge case as such can be abandoned. The ballistic characteristics of the bullet will, of course, change, but it’s unlikely to change dramatically.

This scheme is not suitable for a powder charge: the bullet-case turns out to be quite long and has mediocre ballistic characteristics. But if the propellant charge turns out to be only a fifth of the powder charge, then such a cartridge in the form of a bullet-case turns out to be quite possible.

There is no need to say how important it is to reduce the weight of ammunition and reduce its size. Such a radical reduction in the size of the same pistol cartridge that it shrinks, in fact, to the size of a slightly enlarged bullet, creates great prospects for the development of weapons. Reducing the size and weight of the cartridge by almost half means the possibility of increasing the magazine. For example, the PP 2000, instead of magazines for 20 and 44 rounds, can receive magazines for 40 and 80 rounds. The same can be said not only about the 9x19 cartridge, but also about all other cartridges for small arms.

Third. Modern containers for storing hydrogen peroxide and mixtures based on it are made of polymers: polystyrene, polyethylene, polyvinyl chloride. These materials not only provide safe storage, but also make it possible to create a capsule for loading ammunition that is inserted into the cavity of the bullet. The capsule is sealed, equipped with a capsule. The capsule in this case is a relative concept. Hydrogen peroxide does not need to be ignited like gunpowder, but rather a very small amount of catalyst must be added to it. Essentially, the “primer” in this case is a small nest in a plastic capsule containing the propellant, where the catalyst is placed. The strike of the striker pierces this socket, its bottom, separating it from the propellant, and presses the catalyst inside the capsule. Next, the decomposition of hydrogen peroxide occurs, the rapid release of steam gas and a shot.

The capsule is best made from polystyrene. It is quite durable under normal conditions, but when heated strongly, above 300 degrees, it decomposes into the monomer - styrene, which, in turn, when mixed with oxygen present in the steam gas, burns well and even explodes. So the capsule will simply disappear the moment it is fired.

A polystyrene capsule is produced incomparably lighter and simpler than a sleeve. It is easy to stamp hundreds and thousands of pieces on a heat press in one pass. Numerous (more than a hundred!) operations for the manufacture of a metal cartridge case are completely eliminated, and the technological equipment for producing a shot is dramatically simplified. The relative simplicity of production means the possibility of mass production and its expansion if necessary.

However, it should be noted that cartridges filled with hydrogen peroxide will need to be manufactured immediately before use, with a maximum shelf life of 3-4 months. The longer such a cartridge is in storage, the more difficult it is to guarantee that it will work. But this circumstance can be circumvented in the following simple way: equip with fresh hydrogen peroxide or a mixture based on it only those batches of cartridges that will immediately go into use. It will be necessary to change the very sequence of ammunition manufacturing. If in conventional cartridge production the cartridge is loaded with gunpowder before mounting the bullet, then in the case of hydrogen peroxide the final stage of ammunition production will consist of pouring it into the already assembled ammunition. Hydrogen peroxide can be poured into the capsule already installed in the bullet using a thin needle (aluminum or stainless steel - materials acceptable for working with this substance), followed by sealing the hole.

Because in Peaceful time it is possible to prepare a sufficient mobilization supply of “dry” cartridges in order to quickly launch the production of fresh hydrogen peroxide and accelerate the equipment of these supplies in case of war.

However, some of these cartridges can be kept in warehouses and fully loaded. After the expiration date, the hydrogen peroxide in them can be replaced without disassembling the ammunition: using a thin needle, first pump out the already unusable propellant mixture, and then pour in a fresh one.

In general, if you decide to make major changes related to the design of the cartridge, the design of the weapon, as well as the technology of cartridge production, then you can introduce a new propellant and obtain a whole range of military, economic and tactical advantages associated with its use. These advantages, as can be seen, will be very far-reaching and will affect all aspects of preparation for war.

What happens if you weld cartridges?

The unscientific experiment, conducted by the magazine Master-Ruzhye, was carried out in laboratory conditions (an armored room) with constant visual monitoring of the cooking process. We strongly recommend that you, dear readers, believe in the results of these tests and do not try to repeat them in practice: in the kitchen, on garden plot and so on. The illustrations for the article, except for the target, are, of course, staged shots. We are giving this warning for a reason. After the article was published. Rail War. non-believers were found who repeated that experiment in the field. conditions and joyfully reported this to the editor: .And it’s true, it didn’t hit, but the ricochet whistled right over my head!..

I’ll paraphrase Said from White Sun of the Desert: DON’T DO THIS, DON’T!

In a wonderful domestic film. Roadblock. There is a moment when fighters cook machine gun cartridges with the aim of later using them as hard currency in business. relationships with.fairies.. From various independent sources, I also received information about this and other methods.of finishing. ammunition before handing it over to a potential enemy. Moreover, the subtlety of such modernization is not to make the cartridge unsuitable for shooting, on the contrary, the whole outer side shot. the sound, sensations, and operation of the reloading mechanism should remain without visible changes. But the ballistics of the modified cartridges should exclude the possibility of their combat use at any significant distances.

Not that I have any doubts about the existence of such a practice at all or about the effectiveness of the techniques used. Rather, on the contrary, remembering that practice. criterion of truth, I decided to establish the exact time and operating parameters for processing cartridges to bring them to the desired level (in certain cases) state.

It must be said that popular rumor offers several more culinary options. recipes that give (presumably) similar results to the cinematic version. Let's consider several proposed methods, the effectiveness of which we will have to confirm (refute) during experiments.

7.62x39 cartridges are cooked for a certain amount of time, after which they lose their combat properties.
It is not necessary to cook the cartridges for a long time; the main thing is to quickly cool the very hot cartridge.
It takes a long time to cook, but it takes a long time to cool. slowly, allowing the cartridges to cool quietly in the water where they were boiled.

A little theory

From a physical point of view, for a noticeable change in the ballistics of a bullet, you just need to reduce its initial speed by about 300 meters per second. At a distance of 100 m, this will lead to such a decrease in the trajectory that, with normal aiming, it will be problematic to hit a chest target, and at 200 m, a height target. What factors can lead to such success?
Assumptions

Partial decomposition of the primer composition, weakening of the force of the primer flame and, as a consequence, . incomplete combustion of the powder charge (often observed in hunting cartridges when using old centrifuge-type primers).
Wetting of the primer composition and the powder charge due to water seeping into the cartridge.
Partial thermal decomposition of a powder charge.

In my opinion, from three versions Only the third deserves serious attention. The first assumption is unfounded, since the thermal stability of initiating substances significantly exceeds the potential of culinary substances. opportunities ordinary person. The second assumption is very plausible. However, getting the powder charge wet will lead to the complete loss of the cartridge's combat properties, and this. not our option. So, the third version. It must be said that the low chemical and thermal resistance of nitrocellulose, which forms the basis of most smokeless powders, was a big problem for chemists and the military in late XIX century. And the point was not only that it was not possible to completely purify nitrocellulose from the remnants of the acid mixture used for nitration.

Slow, spontaneous decomposition of nitrocellulose molecules occurred with the release of the nitric acid radical NO2,. as a consequence, the acidity of the environment increased, and the rate of decomposition process increased many times over. Played a decisive role temperature regime. With an increase in temperature by 10., the speed of the process doubled. Thus, the rate of self-decomposition of gunpowder with an increase in temperature from 0. to 100. C increased by 1024 (!) times. Later, special substances (for example, diphenylamine) began to be introduced into the composition of gunpowder, the function of which was to bind excess acid that inevitably formed during long-term storage of gunpowder. The durability of gunpowder has increased significantly. Under normal storage conditions, cartridges and shells remained suitable for firing for decades. However, boiling for several hours cannot be recognized normal condition storage, so it was with this path that I pinned the greatest hopes when starting experiments.
From words to deeds

For the easiest test, I soaked a pack of Klimov FMJ cartridges in a nickel-plated case in water for one week.
Some of the cartridges (made in Barnaul) with the SP bullet were boiled for one hour.
Some of the cartridges from the same batch. in two hours.

According to unverified information, 30 minutes of boiling is enough to disable a 9 mm PM cartridge, so with an automatic cartridge I decided to stop at the 2-hour mark.

I’ll say right away that when I went to the shooting range, I prepared for the worst. The effect of the treatment was difficult to predict, and the prospect of a bullet getting stuck in the barrel seemed very likely to me. One of my acquaintances told me with sympathy that in the army stuck bullets were removed using a special rod (a regular ramrod was bent), a concrete wall, etc. An armored personnel carrier that pressed on the rod. In my army practice, there were no such cases, and I also did not specify why the bullets got stuck in the machine gun barrels, but I went to the firing line with a restless soul.

The target was placed at the 50th mark, and I didn’t particularly hope to hit it. Shot!.. Another one and another. All 10 shots went through without delay, forming a completely normal group of about 60 mm on the target. Having fired, I hurried to the speed measuring device, secretly hoping to see the expected 600 m/s. Nothing happened. The speeds were about 700-715 m/s at a distance of 20 m from the muzzle. Uncooked cartridges from the same batch gave approximately the same speed.

It was the turn of the two-hour game. And again, not a single delay. The chronograph showed a minimum speed of 697, a maximum. 711. And no downward trend. Frankly, this was a real disappointment. Klimov cartridges, soaked for a week, worked depressingly monotonously (708-717 m/s). .Strong Soviet authority., . I thought and decided to increase the cooking time to 3 hours. It's been said. made. A week later I arrived at the shooting range with four loads of ammunition.

Barnaul. S.P. 3 hours.
.Klimovsk. HP (without varnish filling). 3 hours.
.Barnaul. FMJ. 3 hours with rapid cooling in the freezer.
The same, but with a smooth cooling in the original. water.

The very first speed measurement really shocked me. The chronograph showed 734, 737, 736, 739. .This cannot be., . I thought. The misunderstanding was cleared up very quickly. the device was standing in three meters from the trunk, and not twenty. like before. The deceleration speed of a bullet is about 1 m/s for every meter of distance. Thus, at 20 meters the device would show the same 710-715 m/s as last time. The control group cartridges at 3 m showed 735 m/s. Only one shot from boiled cartridges gave 636 m/s. The cartridges of the second group misfired twice per 10 shots. In the absence of varnish filling of the cartridge case neck and primer, water managed to get inside, which was confirmed later when I sawed the misfire cartridge. The gunpowder was thoroughly wet and did not even fall out. In refutation folk recipes, cartridges of the 3rd and 4th groups worked exactly the same as the others. The idea of ​​the article collapsed before our eyes. Angry at the failure, the pouring rain in which the shooting was carried out, the cinematography and everything in general, I decided to take the last step and cook the cartridges for 5 hours.

In general, setting up experiments of this kind. It's a pretty routine thing. The main concern of the experimenter. do not allow the water to completely boil away. After 5 hours of boiling, half of the cartridges were immediately removed from the water, and I let the second one cool slowly right in the broth. Frankly, I did not see a fundamental difference between the methods; the only reasonable explanation was the following: if the gunpowder really decomposed under the influence of high temperature, then the resulting gases had to be released through damage to the varnish fill. As it cooled, a vacuum should have been created inside the cartridge, and water should have been sucked in through the same damage to the filling. The truth of this assumption was to be determined at the shooting range.

The practical result of firing 7.62x39 RMZ cartridges after a five-hour boil: seven hand-held shots at a distance of 25 meters.

I’ll tell you straight, when I went to the firing line, my secret sympathies were already on the side of the Barnaul machine tool builders, and not the recipes of folk cooking, as before. First, the first batch of cartridges (Barnaul FMJ) were tested. The chronograph stood five meters away. The target hung at twenty-five. The very first shots showed the unconditional superiority of the machine production method over the pitiful efforts of a single artisan. The chronograph was relentless. 738, 742, 746, 747, 749, 751, 759 (!). The bullets lay flat. One break. entirely my fault. The speed values ​​even seemed a little high to me. The question is whether the growth initial speeds result culinary processing or a feature of a given batch of cartridges, remained open. The cartridges of the second batch (those that cooled in water) also did not cause any misfires or malfunctions in the automation. Accuracy was normal, however, measuring the speeds of 10 shots in three cases resulted in a decrease in speed to 673, 669, 660 m/s.

At this point I decided to stop conducting experiments. No, no, dear reader, it’s not that my research enthusiasm has dried up. The speed reduction values ​​obtained as a result of the experiments were still infinitely far from the desired 400 m/s. And here appearance cartridges after 5 hours of cooking are more than three. obviously didn't pull it off. Rough to the touch, covered with a whitish coating of scale, with a noticeably peeling varnish coating of the cartridge case, with the varnish filling of the cartridge case swollen like a soggy bread crust, they have clearly lost their presentation. You didn't have to be an expert to understand that there was something wrong with the cartridges.
Instead of a conclusion

It is possible that the statistics I collected are not sufficient to make broad generalizations. Possibly soldiers of the checkpoint. They cooked the cartridges not for five hours, but for five days, taking turns watching the pot. Perhaps you should cook not in water, but in some higher boiling liquid, for example, oil. One way or another, in my case, domestically produced cartridges showed the highest resistance to all kinds of force majeure circumstances. I can only console myself with the fact that I remember the ax in the old soldier’s tale. also remained undercooked.

Soldiers and sailors, sergeants and petty officers, officers of all branches of the military, love Russian cinema, but remember that the truth of art may not always coincide with the truth of life!

The very idea of ​​this method of charging a cartridge appeared back in the days
First World War.

When German soldiers When they saw that their rifles could not penetrate the armor of British Mark I tanks, they decided to try loading the bullets with the point inside the cartridge case.

And to their surprise, the bullets began to dent the armor. Because of this, the armor crumbled inside the tank and maimed the crew. But then the soldiers discovered that firing such cartridges often disabled rifles and injured the shooters themselves, and this method of loading cartridges was abandoned.

Then the Germans adopted armor-piercing bullets, and British tanks became vulnerable again.

Bullets Loaded Backwards

The video tested the killing power of a bullet charged in this way. When hitting the ballistic gel, the bullet does more damage than a standard bullet.

Neither bullet nor the other penetrated sheet steel. But it completely tore the water bottle, unlike the traditional one, which simply pierced it right through.

But there was also a downside to such cartridges, namely a cracked cartridge case. So, if you care about your safety, it is better not to repeat this.
