Cartridge .357SIG

It is very often possible to meet the phrase that this or that cartridge is made on the basis of another ammunition. Usually this relationship is perceived too explicitly, although the patrons have not so much in common. It is clear that when they say that one cartridge is made on the basis of another, they most often mean that the design took into account the experience of previous developments, but actually the ammunition in common, for example, the size of the sleeve, is not a prerequisite. But there are exceptions, which can really be said that they are actually made on the basis of other cartridges. One example of such an exception is the .357SIG cartridge, which is made on the basis of the .40S & W cartridge case, pereobzhaty under a nine-millimeter bullet, well, almost nine-millimeter. I will try to tell about this ammunition in this article.

Cartridge .357SIGThis cartridge appeared not so long ago in 1994, thanks to the work of the designers of SIG-Sauer with the participation of specialists from Federal Cartridge. The main goal was the creation of ammunition, which would be superior in its characteristics to the popular .40S & W, but at the same time had a reasonable return when shooting, and was also relatively cheap. In other words, the main idea was to shake the popularity of .40S & W, and the designers succeeded. It was possible to do this with a minimum of body movements and with the maximum result. It was possible to obtain higher performance by simply reducing the caliber of the cartridge when re-crimping the liner for a new bullet. Immediately, the first positive thing was that it became possible to use the new ammunition in the pistols, which were originally designed for the .40S & W cartridges, simply by replacing the barrel, the magazine, the bolt, they all remained in their places and did not require replacement. Many manufacturers were quick to add another barrel to their .40 caliber pistols, which really increased sales. weaponsreally not for long. With the active use of .357SIG cartridges in weapons designed for .40S & W ammunition, pistol wear significantly increased, and therefore it can be said that simply replacing the barrel is not a normal adaptation of the weapon for a new ammunition. Despite this, many manufacturers still complement their pistol sets with only one barrel, although not a smaller number of manufacturers simply created parallel models of weapons already fully calculated for the new ammunition. Thus, some interchangeability between .40S & W and .357SIG is preserved, but it cannot be called complete.

In addition, it is worth noting that, thanks to a new form of ammunition, the supply of ammunition during reloading has improved, which in general has increased the reliability of many samples. Due to the fact that the powder charge remained the same, and the mass of the bullet was significantly reduced, the initial speed of the bullet increased, and its trajectory of movement became more flat. Reducing the caliber also led to the fact that the bullet began to have better penetrating power, which allowed the ammunition to maintain its trajectory during the passage of light obstacles, as well as to hit the enemy in the means of individual armor of a low class.

It is also necessary to mention that when firing this cartridge creates quite comfortable return comparable to .40S & W, however, the kinetic energy of the bullet is comparable to the bullet of the .357 Magnum cartridge. .357SIG cartridges can be equipped with various bullet options, which actually determines the speed of the bullet. Thus, the standard cartridge with a bullet weighing 6,12 grams accelerates into a 100 millimeter barrel to a speed of 460 meters per second, the “fastest” ammunition is characterized by the speed of a bullet in 520 meters per second. The kinetic energy of the bullets can reach 820 Joules, while the .40 S & W has a maximum of 790 Joules at a speed of 360 meters per second.

Thanks to a well-thought-out advertising company, this cartridge quickly gained popularity, and even government customers could not resist the pressure of advertisers. If you evaluate soberly given ammunition, then it is really good, but it is far from being good for everyone. So, for the civilian market as a cartridge for self-defense, I still like the .40S & W with an expansive bullet. The possibility of hitting the enemy in a bullet-proof vest, and of a low protection class, is better left to law enforcement officers and the army. Say what you like, and the heavy slow bullet .40S & W allows you to certainly stop the enemy, regardless of where you hit. A higher speed for self-defense purposes is also not needed, since short distances for the use of weapons simply do not provide a clear advantage. But for amusement and sport shooting this ammunition already has a really tangible advantage in comparison with .40S & W. In general, there is no way to call .357SIG a full-fledged replacement for .40S & W.

The problem with the adaptation of weapons for the new ammunition was partially solved by the craftsmen, who simply replace the return spring of the pistols with a more rigid one. This reduces wear on the parts of the pistols when using the .357SIG, but their life is still less than that of those models that were originally designed for this ammunition. In addition, due to the high pressure in the barrel when fired, the resource of the barrels for this ammunition is not the highest. This problem could be partially solved by barrels with a polygonal rifling, but for some reason they are used with this ammunition very rarely.

Summing up, it’s impossible not to say that the .357SIG cartridge turned out to be very good, but it cannot be a replacement for the .40S & W as the manufacturer wants to convince. In some ways this ammunition is definitely better, but in some moments it is still inferior to .40S & W. A super armor-piercing cartridge for a pistol also did not come out of it, so, nevertheless, this cartridge complements, and does not replace, the already widely distributed ammunition.

PS Do not look at the fact that the cartridge looks funny, the appearance of the ammunition is not determined by the appearance.

    Interesting topic. Both cartridges are good in their own way. But not everything is so simple when compared with the effectiveness of ammunition, especially pistol / revolver. The only indicator of the effectiveness of the ammunition is the time required to remove the target from the action (not necessarily fatal, loss of consciousness or paralysis is acceptable). Therefore, an indicator of the effectiveness of the cartridge are the seconds elapsing from the moment a bullet hits the target until the moment the target is “turned off”. The most effective way to instantly “knock out” a target is to hit the head. But the hardest thing to get into your head. The most realistic option is hitting the torso. This is where the little channel begins. The speed of the bullet and muzzle energy are not the only indicators of effectiveness, there is also the caliber and shape of the bullet.

        Cyril, welcome. here, even experimentally, not everything is so simple. There was a theory of knockout Marshall and Senou. These comrades evaluated the effectiveness of pistol cartridges by studying real cases of police shootings with criminals. According to the results, it was concluded that the most effective cartridge was 367 magnum with a bullet PMG, if the memory does not change, that is, ammunition with a sufficient penetration depth. In Europe, another study was conducted - in Strasbourg, Alpine goats were shot (in mass and dimensions and in the internal structure of organs similar to humans). According to the results of the Strasbourg tests, the most effective ammunition was 38 space-based bullets with the Safety slug bullet (a bullet like a container with shots inside) and expansive (hollow point) bullets.
        Z.Y. and goats sorry)))

            I don’t remember exactly, but it seems that American analysts have calculated that the effectiveness of the stopping action of one shot of a well-guided tactical nuclear warhead is approximately 117%))))))

              According to the unwritten laws of war, captured soldiers convicted of using expansive bullets,
              often shot on the spot.

              True, the ban on the use of such bullets applies only to regular armies.
              Cartridges with bullets like JSP HP and JHP are often used by police, hunters and for self-defense
              due to a small ricochet and a large stopping effect when shooting at an unprotected target.
              Some countries are in “free sale”.

              stopping efficiency

              The stopping effect is pronounced in blunt bullets.
              They penetrate relatively shallow, but create a powerful shock wave that causes
              volumetric concussion and contusion of adjacent organs and tissues.

              So .357 SIG will be more effective than cartridges for PM and PSM,
              and the recoil is less than that of Luger / Steam cartridges.

              Although from my own experience I know that often one kind of weapon is enough for self-defense.
              Well sobering clang cocked shutter.
              And if a brawl is already taking place - a warning shot in the air and a couple of strong expressions on Dahl.

                  Maybe your stores have everything you want.
                  In our outback there is a "wide choice":
                  Russian, Ukrainian and Czech cartridges for several common calibres.
                  And the 357 SIG cartridges and the Tres Haute Vitesse bullets in our stores were never seen.

                  I have a desire to buy a house, but I do not have the opportunity.

                That is yes. Cavitation wave damage to internal organs is effective only for supersonic bullets, of which 357 Zig is. But the best result on the cavitation wave was shown by the French bullet THW

    One example of such an exception is the .357SIG cartridge, which is based on the .40S & W sleeve, over-compressed under a nine-millimeter bullet

    Weapon history knows quite a few examples of "over-compressed" ammunition:
    - The .338 Winchester Magnum cartridge (.338 Win Mag) was developed in 1958 for the Winchester M70 Alaska bolt rifle based on the .458 Winchester Magnum cartridge sleeve, crimped to .338 caliber
  4. self-propelled
    self-propelled 10 July 2013 23: 17 New
    I will continue my comment (something does not hang request )
    - The 6.5 Grendel cartridge (6.5x38) is a modified version of the PPC family of cartridges, which are based on a slightly modified sleeve of the Soviet cartridge 7.62x39 mm with compressed dulce to the required caliber
    - The 6.8 mm Remington SPC ammunition was based on the basis of the .30 Remington cartridge, in whose case the cone was lowered, shortened and pereobzhali dulce under the new caliber
    6.8 mm Remington SPC

    - The cartridge .330 Mars is very similar to .360 Mars. He, like the 9 mm cartridge, was created by crimping the cartridge case .450 Mars Long and giving it a bottle shape to accommodate a smaller caliber bullet (by the way the dead cartridge was developed back in 1899)
    .330 Mars

    so, "nothing is new under the moon." the whole point is how much the fighting qualities of the "over-compressed" ammunition exceed the progenitor. and are these advantages worth the money that will be spent on transferring production to a new munition and releasing “remade” (or creating new) weapons for this munition ... request

    Fashionable ammunition, but I find it harsh, however, many leading brands produce models for it. My subjective opinion is that, as mentioned above for this munition, you need a forged barrel with polygonal cutting (as in Glock), although the latter will kick significantly in view of its low weight, and the Browning system is not the best option for magnum ammunition. He would have created an independent model from the beginning for him, but with thoughtful locking (gas exhaust or roller lock Well, something like that))) I personally prefer 9x21.

    Great cartridge! I have, among others, 2 pistols in this caliber. For entertainment purposes, the cartridge is just a gift, plows louder than everyone else and has a pleasant, enjoyable, tangible impact. For sports shooting cartridge is not very good. This is due to the high return and, as a result, to an increase in the time the pistol returns to the sighting line and firing repeated shots.
    Fortunately, I did not have to shoot this cartridge at the recipients, but I think that the cartridge 9 * 19 for self-defense or everyday police needs has an advantage. With a good and accurate hit in the body of the attacker, the latter will be just as effectively disabled by the 9 * 19 cartridge. When using the .357SIG cartridge in extreme conditions, there will be worse accuracy and speed of shooting, which will reduce the likelihood of hitting targets, especially if the shooter is not adequately prepared.
    Hence the conclusion - the 357SIG caliber pistol is perfect:
    1. For recreational shooting;
    2. For employees of special forces with good training;
    3. For killers.
    In other cases, the choice of a different caliber is preferred.

    By stopping action, a comparison of these ammunition at the level of boltology. The basic version of the .357SIG ammunition is the option with an expansive bullet weighing 125 grains (8.1 grams). Get an expansive bullet with kinetic energy from 700 to 890 j. not the best option.
