Hand gun

Hand gunHand-gun - this is how the full name “Rucni Top” of a large-caliber RT-20 Croatian rifle is deciphered. This mini-monster was created in the middle of 1990, during the Serb - Croat conflict after the collapse of the allied Yugoslavia. The main purpose of the RT-20 was the fight against equipment, including lightly armored. RT-20 is manufactured by RH-Alan and is in service with the Croatian army.


Large-caliber sniper rifle RT-20 - this is probably one of the most interesting sniper samples weapons. Let's start with the fact that this rifle is one of the most powerful mass-produced ones, while the rest of the 20 caliber weapons of millimeters are based on a weaker cartridge, and those rifles whose caliber exceeds 2 centimeters are literally made of pieces. The production of this rifle fell on the time of the Serbian-Croatian conflict precisely at that time it took a weapon that could penetrate all types of personal body armor at long distances, and also effectively deal with enemy snipers at distances inaccessible to their weapons. This model is available rifle Croatian company RH-Alan. Very well gives the characteristic rifle its name Rucni Top? Which translates as a hand gun, and why it is so called below.

As with any weapon in this rifle, the base is ammunition. The RT-20 is a twenty millimeter projectile (20x110) from the Hispano Suiza HS 404 anti-aircraft gun. At the moment, the release of high-explosive, armor-piercing and armor-piercing incendiary ammunition has been adjusted, the weight of such a cartridge-cartridge is about 130 grams, and the powder charge accelerates it to 830 meters per second. In order to tentatively imagine what kind of energy a given projectile can draw an analogy with the NATO standard 12,7X99 cartridge, the recoil created by firing the 20х110 cartridge is four times the return of the 12,7 caliber cartridge, of course, the weight of the weapon and so on also plays a role, but An example of such a comparison is quite suitable.



If we compare with the cartridges 20x82 from the German aviation the guns that are used in the large-caliber rifle TEC-20, the power of the cartridge 20x110 is twice as large. In other words, the energy released by the cartridge during the shot is very large, and here we must pay tribute to the skill of the gunsmiths, who found a way to control it. The first thing that comes to mind when comparing 20x110 ammunition with other ammunition is the issue of giving back weapons. If in anti-aircraft guns this question was significant insofar as since no one had the idea to shoot it without a machine gun, then in manual weapons this question is more relevant than ever. Of course, in order to dampen recoil, a massive and effective muzzle recoil compensator is required, however we know that the most effective of them can absorb 30-35 percent, and we should not forget that the muzzle recoil compensator sends powder gases under angle to the arrow, from which the ears of the arrow, to put it mildly, do not feel comfortable.

The RT-20 large-caliber sniper rifle has a massive three-chamber muzzle brake, and, complete with a weapon, you can find huge headphones that look more like a torture tool used by the Inquisition in the Middle Ages, because they squeeze the skull box very tightly. But if you choose between contusion and such inconvenience, the choice will naturally fall on the latter. But this is all quite expected from the weapon, but the pipe located above the rifle can cause a number of questions. The fact is that to compensate for the recoil of the rifle used jet thrust created by the powder gases. A series of holes are made in the barrel of the rifle through which the powder gases enter this so-called reactive system, as a result of which the rifle pushes forward the jet thrust forward and the recoil pushes it back, and both forces cancel each other out.

Such a recoil compensation system could not only reduce it to zero, but even make the weapon move forward, however, it should be borne in mind that the powder gases entering the jet system could usefully work, accelerating the bullet in the barrel, therefore, completely remove the recoil of the weapon the best way to use the system, as it takes energy from the bullet in the barrel, but to reduce the percentage on 40-50 without a significant reduction in the energy of the bullet is quite realistic. Thus, there remains the order of 20-30 percent recoil, which will be painfully perceived by the shooter when fired. In order to reduce them on the butt of the weapon, the butt plate-accordion is placed; at the moment of the shot, a small part of the powder gases gets into it and causes it to expand, thereby compensating the recoil, as a result the shot from the “hand gun” does not cause more inconvenience than we say a shot 12,7 caliber rifle weighing 10 kilogram.



Naturally, such a system of recoil damping has a number of negative sides, firstly, it is a flame escaping from a reactive recoil compensation system. And the point here is not so much that you cannot shoot a rifle in a closed room, or you need to look around every time, is it not worth someone behind your back so as not to fry your comrade. The main problem of such a system is that when fired, the position of the sniper immediately becomes open, and even if the enemy does not see the flash when fired, he will easily determine where the sniper is on the smoke trail. And even if all this can be skipped, it is enough to look at the terrain through a night-vision device based on infrared radiation to see where the sniper is, as the tube of the reactive recoil compensation system will glow brightly and clearly due to the high temperature. Unfortunately, the pipe itself, like the rifle, is not covered with non-conductive heat paint, on the other hand, the effective range of the weapon is about two thousand meters, which somewhat mitigates this drawback.

Arranged weapons according to the bullpup scheme, which reduces its size, but in this case imposes a number of drawbacks. So if other rifles can be fully serviced by one person, then at least two people need to be fired from this weapon, this is due to the fact that the rifle bolt is far behind the pistol grip, and in order to reload the shooter it is necessary to remove the weapon from the shoulder, move relative to the rifle back and make another lot of manipulations that not only unmask him, but also reduce the rate of fire. While the second person from the sniper calculation can spend on reloading less than 20 seconds. 20 seconds seem to be quite a long period of time for recharging, but here it must be borne in mind that after the shot at least 5-10 seconds should pass only after that it will be possible to remove the empty sleeve. Open sights RT-20 does not have, which is understandable. The optical sight is mounted on the bar installed at the junction of the barrel and the reactive recoil compensation system on the left side. The rifle has a massive bipod fixed in the front of the forearm, which can be adjusted in height, given the weight of the weapon and the recoil force, shooting from the hands is not only contraindicated, but simply impossible.


Sniper ammunition: SP-5 (9h39), 7,62x54AR, 338 Lapua Mag, 50MBG (12,7x99), 12,7x108, 20x81 Mauser, 20x110 "Hispano-Suiza".


The RT-20 large-caliber sniper rifle is a formidable weapon both externally and in practice, and it poses a threat to lightly armored vehicles and means of location and communication. This weapon has no equal among other sniper rifles, both in power and weight, so the rifle itself can be easily disassembled into two modules, each weighing about 10 kilograms, which are carried in shoulder bags by sniper calculation.

      Well, this is no ordinary small arms. And if you beat with 2 km, then you still have to suppress the calculation with what. For example, if from such a fool they will shoot at the positions of the radar company or according to the composition on the railway, then the guard will need to run a kilometer so that it would at least somehow cover it. Yes, even on a single armored personnel carrier, she will shoot, and then the calculation will run away easily.

          dear Denis

          2 kilometers for such a charge is not completely gone. Hispano Suiza HS 404 with a barrel of 1100 mm gave max. long distance
          6400 meters. http://en.wikipedia.org/wiki/Hispano-Suiza_HS.404

          but the main problem of the weapon is that the shooter must be an elite sniper.

          after taking into account the density of air, calculating balistica, the Magnus Effect, we must also recall the Coriolis Force.

          during a shot at a distance of 2000 meters, the Coriolis Force alone can give up to 14 centimeters of deflection.

          and after all that, you may need to quickly tick from 20-25 kg. equipment if the Serbian armored personnel carrier of the sniper noticed.

        Shooting from above 1000 m is considered very difficult and requires additional equipment and a cool pro.

          Add: more luck. The bullet does not fly at the speed of light, and it will cover a distance of 2 km in 40-60 seconds, during which time, if the target is not nailed to the ground, it will have time to dump a lot where.

              At the INITIAL speed of 800m / s. And so the speed will fall below the sound already at 500-600m. And then it will fall very sharply. You know, he has air resistance. Although with a minute I bent, but for 20 seconds it will definitely fly.
              In addition, when the speed drops below the sound speed, the behavior of the bullet on the trajectory changes very significantly, and not for the better.

                  So the air at such speeds for the bullet is just as jelly and will be. Did you know that at a speed of 2-3M the resistance is approximately proportional to the speed cube (although the dependence is more complicated there)?

                  Unfortunately, I did not find it, but just look at the data on other ammunition to understand this. By the way, for comparison, an LPS bullet fired from a rifle with an initial speed of 840 m / s after 3 s will only be at a distance of about 1300 m and have a speed of about 200 m / s. You can check it out.

                    And something for the sub-caliber tank shells is a loss of speed and does not closely resemble those described by you.

                    and I’ll bring it from the naval artillery - not quite that, but the air and speeds are the same, and the air resistance is even greater due to the larger cross-section of large-caliber shells.

                      Absolutely off topic. For both examples. The same laws of physics work there, but in slightly different ratios than for less massive shells with a lower transverse load. The comparison is not correct.

                        It seems to me in this case it is not entirely correct to compare the SVD 7,62 mm and 20 mm rifle. And the tone of the dialogue has slipped to the next insults.
                        I downloaded the 1984 NSD on KPVT (14,5 mm closer to 20 mm). So:
                        Distance 100m - bullet speed 905 m / s, total flight time 0,11 s
                        Distance 2000m - bullet speed 338 m / s, total flight time 3,7 s.
                        So for 20mm there is no need to talk about any 40 or even 20 seconds at a distance of 2 km.

                        You are trying to compare the PTR with an initial bullet speed of about 1000 m / s with an aggregate that accelerates a 20 mm projectile to 800 m / s. These are two very big differences.

    12,7 mm bullet from the NSV machine gun passes 2000 m in 4,47 s. I do not think that a 20mm shell will fly by less than 3 and more than 5 seconds.

    Range is her great secret
    Armor-piercing shells (of French design) ensure penetration of 20-25 mm steel armor (homogeneous, medium hardness) at an angle 60 from the distance 200 m.

    All that I managed to find. Next PTR, but here is the weight and return
    Again it’s aimed, but with penetration, how?
    In general, it was conceived interestingly, as a PTR with a narrow specialization
    Initially, the RT-20 was created for a specific task - to break through the armor of an infrared sight mounted on the tower of the Serbian M-84 tank (an analogue of the domestic T-72). During the initial stage of the conflict in the Balkans, the use of tanks of this type with an infrared sight created significant difficulties for moving Croatian units at night. In solving this problem, the RT-20 system was so effective that the field of its tactical application was expanded.
    In various sources you can find references to the use of RT-20 to suppress the positions of machine guns and artillery, to fight lightly armored vehicles and enemy snipers at distances inaccessible to their weapons.

    In general, the apparatus is interesting. I see the description here for the second, or even the third time. In general, a 20mm caliber that allows you to solve a very wide range of tasks. And to destroy the IR sight on the M84 tank, a slightly smaller caliber would be enough, but with more high initial speed. And this one, you see under the finished cartridge of the Spanish-Suiza.

      So 20mm without a machine can not hold
      There was an experiment with a 20mm PTR RES, but it’s on the machine
      His cartridge is interesting
      Specially for PTR RES, we designed our own 20x150R cartridge with an armor-piercing shell with a tungsten core. The shell had an aluminum head. The basis for the cartridge case was the cartridge case for the 45-mm anti-tank gun.
      Only the year is 1942, not 1994
      Even then, they did not try to defeat the return of 20mm weapons with the strength of their hands and with the emphasis of the shoulder

      Especially with such a movement, like lice on a comb
      the shutter handle in the normal position is almost behind the shooter, therefore, for reloading he will have to make quite a few gestures that unmask him (although the pillar of smoke after the shot does this quite successfully). It would be possible to “blame” this task on the second person, but do not forget that when fired from a jet tube not only powder gases, but also flames break out. For this reason, the second person will first have to crawl, recharge and crawl back to a safe distance, which will also give the position of the shooter.

    The Croats were not the first, 20mm caliber rifles were created earlier, but today of the common calibers, I think you should not make a caliber rifle of more than 14,5mm range and power is more than enough.
    The Yuarovsk rifle, the NTW-20 which was already mentioned above, also has 20mm ammunition, albeit weaker, but it is a real and real battle weapon, and the Croatian one looks more like a weapon curiosity.
