When it comes to the Olympic 10-meter air rifle shooting competition, it is not false to use the term "embroidery needle kung fu" to describe it. You think: 10 meters away, the athlete lifts an 11-pound air rifle and shoots a 4.5 mm diameter projectile, right in the bullseye, and gets 10.9 rings! How big is the bullseye? 0.5mm!
The last shot of 16-year-old Sheng Lihao hit 10.8 rings to pick up silver
Someone was blindfolded: 10 meters away, and there is no optical sight that can be magnified, how can athletes see the bullseye of 0.5 mm? Even if he had good eyesight, how could a 4.5 mm bullet fall on the 0.5 mm bullseye! - "Old Zhou, are you mistaken about the unit, it should be 0.5 centimeters!" ”
I'm not mistaken, the target used in the Olympic 10-meter air rifle is the standard target set by the International Federation of Shooting Sports (ISSF), its outermost ring diameter is 45.5 mm, and the diameter of the ten rings in the center of the target is only 0.5 mm.
The ten rings of the standard target are only 0.5 mm in diameter
You take a regular signature pen and poke a dot on the paper, the size of a mosquito's ass. That's right, the ten rings are that big. Compared with the needle eye of the embroidery needle, it is not an exaggeration to say that the athletes are compared to the "embroidery needle kung fu".
How big is 0.5 mm
Do you try to stick this piece of paper on the wall and stand 5 meters away, can you see the small black dot? Hard. 10 meters away? Even if you have good eyesight, you can't see this small dot of only 0.5 mm.
So a friend said, how can a shooter hit the 10 rings? Lean on Monty!
If one shot and two shots rely on Meng, it can be understood, after all, shooting has an element of luck, but if the guns and guns are "blinded" by luck to the ten rings, it can't be said. So how did the shooter hit 10 or even 10.9 rings?
The Olympic 10-meter air rifle shooting competition does not allow the use of optical sights with magnification functions, nor is it allowed to install laser sights on air rifles, and athletes can only aim at the target through the bore holes and crosshairs on the rifle.
The target that Sheng Lihao saw in the sight
Noticed the small black dot in the image above that is enclosed by the smallest ring of the crosshair? That's the part of the target paper within 4 rings 10 meters away. The shooter needs to place this small black dot as far as possible in the center of the ring and keep it stable, adjust his breathing and then pull the trigger, and the rest is left to the bullet.
The target paper used for shooting is specially made; the bullet is designed in a shape similar to a thin-waisted wine glass, and its edges are sharp enough to make round holes with smooth edges on the target paper. But the diameter of the bullet is 4.5 mm, and the diameter of the ten rings on the target is only 0.5 mm, how do we score it?
The ISSF stipulates that as long as the edge of the bullet hole hits the white line of the 9 rings, you can think that you hit the 9 rings; similarly, even if most of the bullet holes are in the circles of the 8 rings and the 9 rings, as long as you rub the small white dots of the center ten rings, it means that your score is 10 rings.
The 10-meter air rifle hit the tenth ring
The diameter of the 9 rings on the target is 5.5 mm, and when the 4.5 mm diameter projectile falls completely within the range of the 9 rings, your worst score is also 10.8 rings; and when the hole hit by the bullet is in the middle of the 9 rings, you can get the highest score of 10.9 rings!
The position of the black bullet hole and the center 10 rings determines the score
Now you should understand: if the athlete wants to hit the 10 rings, he does not need to see the 0.5 mm small white dot in the center of the target 10 meters away, but only needs to place the large black dot of the 4 rings in the center of the crosshair circle.
Is it easy to do this? It's not easy!
If a worker desires to do a good thing, he must first use it. To get right, you need to have a good gun and some good projectiles, and you also need to have a heavy suit for shooting, which allows you to keep your body as stable as possible when aiming the gun.
A good shooter needs to go through years or even more than a dozen years of hard training, and they are physically strong enough to maintain concentration for quite a long time. Athletes also need to master the technique of adjusting their breathing, and they can even reduce the speed of the heart beat from 60 to 100 beats per minute to about 40 times through meditation, so that they can complete the shot between two heartbeats.
The athlete fires in two heartbeats
The shooter will usually press down the muzzle little by little from the top edge of the target, while paying attention to his breathing, heartbeat, and muscle flutter. The target is so small that athletes pursue a good result of more than 10.5 rings, which means that the diameter of the bullet is only the size of your small fingernail, and even the beating of the heart can make the bullet off target.
Muscle tremors cause the line of sight to shake
Becoming a good shooter isn't easy, and it's very different from playing CS on your computer or playing a game of "eat chicken" on your phone. You need to have super muscular endurance to maintain physical stability for a long time; at the same time, you need to stay mentally healthy and make Tarzan collapse in front of you without changing color; shooting is boring, and what the shooter diligently strives for is "unchanged", standing there in a few tens of minutes and shooting dozens of bullets in the same position, which requires extremely strong concentration.
Athlete meditation
So you can often see that in the Olympic shooting competition, the athletes are extremely quiet, they seem to be in a state of hypnosis, even if they play a good result, they will not dance like the players in other sports, because only calm can achieve the final victory.
It's not easy to do this, whether it's success or failure, our brains secrete neurotransmitters like dopamine, norepinephrine, glutamate, etc., which stimulate our neurons, make us excited, and muscle fibers involuntarily contract and tremble. And this shiver is fatal for shooting competitions, you have to overcome it, it's too hard! Even the best athletes, they may not be able to control their emotions when they finally shoot, and eventually make a big mistake and regret it for life.
