Brother One Brother who understands the gun is the official account of the military sub-face light martial arts column, interesting and informative, updated daily!
Let's look at a GIF like this:
In other words, we should be familiar with this scene, which comes from the 1981 Hong Kong movie "Modern Bodyguard". Among them, the captain Zhou Shichang, played by Xu Guanwen, told his subordinates: The finger is stuffed into the barrel of the gun, but the gun will explode, and the finger will be unharmed. This scene also deceived a bunch of small partners including Brother Yi at that time, of course, when we grow up, we will feel that the logic of tucking our fingers into the gun will cause the shooter to be injured is difficult to explain.
It is worth mentioning here that the rumor of finger plugging the muzzle is not exclusive to China, but is also widely spread abroad. Brother Yi can find here that the earliest is the rabbit bugs animation appeared in this meme, and then it is widely circulated in various film and television works.
Of course, this kind of meme from the animation work is certainly not true, let's first talk about the principle of shooting bullets from firearms. When the firing pin hits the bottom fire in the tail of the bullet, the exploding primer ignites the propellant inside the shell, and the propellant begins to burn, while the solid propellant produces hundreds of times the gas when it burns hundreds of times its own volume. The expanding gas pushes the warhead away from the shell and along the barrel.
Since the propellant gives the warhead a force to push forward, it must also produce a reaction force. This force is first transmitted to the shell, and the bottom of the shell is firmly held by the bolt lock, so that the propellant burns the expanding gas to be used mostly to push the warhead.
▲ The gun is firmly on top of the tail of the bullet
The stereotype, or explanation in film and television works, is that if the finger is stuck in the muzzle, then the inflated propellant gas will have nowhere to go, and eventually lead to explosion. So to put it simply, we can directly see this problem as whether it is the bolt's locking and sturdiness, or the finger plug barrel is tight enough, which side is not firm and which side is fried.
But in response to this kind of rumor, foreigners who like to do things have long refuted rumors many times, for example, the Discovery Channel's "Rumor Terminator" also made a special show for this matter in the sixth episode of the fifth season, of course, no one can really try it with their own fingers, they used ballistic gel and artificial skeletons to create a finger simulation finger to simulate this experiment.
And in terms of bullets, they also chose a more fierce shotgun, and the result was directly looking at the GIF:
▲As a result, the artificial hand was directly blasted away
As a result, the artificial hand was directly blown away, and the finger that was stuffed into the barrel of the gun was also blown away. The results of this test are very pleasing to hear, and as you can see in the GIF, it seems that the barrel of the gun is cracked. However, the metal strip that jumped down was actually just a connecting welding rod between the two barrels of this double-barreled shotgun, but the barrel bore was indeed exploded by the instantaneous excessive chamber pressure, which to some extent showed that the foreign body in the barrel would indeed cause the local pressure to surge and lead to the explosion of the tube, but it would definitely not lead to the explosion or injury to the shooter.
Some people may also say: this is only a prosthetic hand after all, lacking the support of the weight of the human body itself. So the Rumor Terminator did a second test, welding a metal finger directly to the muzzle of the gun barrel, and then the test result was like this.
▲ Metal fingers are blown up and the fingers of the flying man don't think about it
The metal bar with a large jump above is actually just a connection welding rod between the two barrels, and the barrel is also exploded at the muzzle, and the chamber and the shooter have nothing to do, and the metal fingers still don't know where to fly. In the show Rumor Busters, the rumor that a finger blocking the barrel of a gun will cause a blast to injure the shooter has become a rumor.
Of course, it wasn't just the Rumor Terminator who did the experiment, but also Demolition Ranch, a foreign gun ring tycoon, who stuffed a carrot in the muzzle of his shotgun, stuffed it quite tightly, and then placed a treated chicken in front of it.
▲ Hu Luo could not affect the gun at all
As a result, the carrots did not know where the explosion had gone, the muzzle of the shotgun had also exploded, and the chicken aimed at the muzzle had been beaten to pieces.
The final conclusion is that the barrel may blow up, but your hand must also be blown up.
In the case of pistols, there is generally a chamber pressure of 100 to 250 megapascals, 100 megapascals is about a ton of weight per square centimeter, and the breech pressure of rifles and the like will be higher. If you want to use the flesh body to counter the power of the gun, it is undoubtedly a pebble to hit the stone, unless there is a protagonist aura, do not try it easily!
