Chapter 2359 Bullet Dragon Teeth

On the battlefield, the effective range of a weapon is very critical and will affect the use of tactics. If a target can be effectively shot from a thousand meters away, who will run to die within 500 meters? Luo Zheng was very concerned about the effective range of this newly developed bullet. If it needed to be shot at close range, it would be of little significance. Dongfang Li understood Luo Zheng's mood, thought about it and said, "Theoretically, it's a thousand meters." , let’s try five hundred meters first.”

"Okay, take your time." Luo Zheng agreed.

Dongfang Ling immediately asked everyone to carry the targets out to the shooting range. Luo Zheng told Lan Xue to go down and not to watch. The contents of the experiment were sealed. The bullets were top secret and could not be disclosed, even if Luo Zheng believed that the brothers in the Secret Bureau were very careful. Be loyal and won't leak secrets, but you have to consider the eventuality.

Everyone came to the shooting range, and the target in bulletproof armor was placed 500 meters away. Luo Zheng skillfully raised his gun and aimed at it. The 500-meter target was no problem for Luo Zheng. He stayed calm and locked the crosshairs. The target's heart was positioned, and his hands were as steady as a rock, motionless.

"Phew -" Luo Zheng fired, and the bullet whizzed out of the barrel with Luo Zheng's expectations. The sound was obviously sharper than ordinary sniper bullets. Luo Zheng felt that the bullet was flying much faster. It was a strange feeling, thinking. Before he could react, he saw the standing target being knocked to the ground.

Luo Zheng curiously rushed forward with the gun in hand, his eyes fixed on the target, his heart clenching nervously, hoping to succeed. Luo Zheng rushed forward quickly with mixed feelings of anticipation and nervousness, squatted down to take a look, and avoided the bullet. A bullet hole appeared in the heart of the armor, like a drill drill, and the bullet disappeared.

The bullet hole was very deep. Luo Zheng touched it with his hand and could feel that the bullet-proof armor had been penetrated. He was immediately overjoyed. He put the weapon aside, quickly opened the target, and unbuttoned it from behind. Lan Xue was also very fast. The second one rushed up and helped remove the bullet-proof armor.

At this time, everyone rushed up and saw Luo Zheng holding up his armor and shining it in the direction of the sun. A bullet hole appeared on the hard armor. When Dongfang Ling saw the bullet hole, his worried expression immediately relaxed and he let out a long sigh. This was The first weapon Dongfang Ling developed since joining the Secret Bureau, if it fails, it will lose its footing.

"Successful, hahaha -" Luo Zheng shouted excitedly: "That's great, five hundred meters is acceptable. Let's test the attack power at a distance of one thousand meters immediately. Dongfang Ling, you have made a great contribution, I will be the frontline The fighting combat troops thank you and take credit for you."

"Sir, you're welcome. This is what I should do. Arrange it immediately." Dongfang Ling agreed in surprise.

Luo Zheng led everyone back to the shooting line. Someone put on the bulletproof armor again and sent the target to the kilometer line to settle down. Luo Zheng stood on the shooting line and took another test bullet from Dongfang Ling's hand and laughed. Asked: "How many test rounds have you made in total?"

"Three shots, this is the second one, there is one left, wait a moment." Dongfang Ling agreed quickly, looking at the colleagues around him and asking: "Quick, all the equipment is in place, the whole process is filmed, move quickly. "

"Yes." The staff around him quickly agreed.

Luo Zheng looked at Dongfang Ling curiously, and Dongfang Ling explained: "We need to collect data, from the bullet coming out of the chamber to flying in the void, to hitting the target, muzzle velocity, flight speed, whether it yaws, and more importantly, the rotation speed, the impact The rotation force after hitting the target and the penetration situation, etc., these data are very critical for correcting and perfecting the bullet.”

"You are still the professional. It's a pity that I wasted a bullet. I'm really sorry. I'll give you extra food tonight so I can make amends." Luo Zheng was startled and said apologetically.

"You are joking." Dongfang Ling smiled politely.

After waiting for a while, all the shooting equipment was in place. Luo Zheng couldn't understand what the purpose of these equipment was. They were not like ordinary cameras. There were several placed along the way, and two were placed near the target. Seeing that everyone was ready, Luo Zheng looked at Dongfang Ling glanced at Dongfang Ling and nodded. Luo Zheng immediately raised his gun, took a deep breath, and his face became solemn.

Kilometers are the key distance. If bullets can attack the target at kilometers, there will be more space and flexibility for tactical application. Luo Zheng is looking forward to success. His eyes narrowed into a slit, and his arms were as stable as a rock. He raised his gun and aimed it at the other side of the target's heart, feeling a little nervous.

"Whoops -" Luo Zheng still fired decisively. The sound of the bullets whizzing out of the barrel was like the roar of an angry tiger. It shook the mountains and forests, and a group of people fought against each other. The bullets flying at high speed made a sharp sound, like a dragon's roar. It irritates people's eardrums, buzzing, and makes them feel sick.

The bullet drew a terrifying streak of air in the air and hit the target accurately. The target was knocked out again and rolled to the ground. Luo Zheng rushed forward with the gun in his hand, his eyes shining, full of desire and expectation. Soon, Luo Zheng rushed to the target a thousand meters away. When he saw the target lying on the ground, he quickly squatted down, put the sniper rifle aside, unbuttoned the armor, and took off the armor.

There was no bullet hole on the other side of the armor's heart, but the bullet was stuck. Fortunately, most of it was submerged in the armor. Although the bullet failed to penetrate the armor, it also penetrated the armor. Seeing this scene, Luo Zheng secretly thought He breathed a sigh of relief, it would be easy to deal with if it could be penetrated. As long as we find the problem and overcome the technical bullet avoidance, it should be able to be solved.

At this time, other people also rushed up and looked nervously at the armor in Luo Zheng's hand. When they found that most of the bullets were stuck in the armor, everyone breathed a sigh of relief and were not discouraged. As long as they could shoot through, it would be fine. It showed that the idea was correct. Dongfang Ling knelt down and looked at it carefully.

Luo Zheng waited for a while, looked at Dongfang Ling and asked, "It should be improved, right?"

"Only, from the sound point of view, the streamline of the bullet edge needs to be improved. The obtuse angle is larger, which creates greater resistance due to friction with the air, which affects the speed to a certain extent. If the speed is not enough and the kinetic energy is not enough, it will not be able to penetrate the armor. , is the spiral angle of these cutting edges." Dongfang Ling explained, pointing to the cutting edge at the front of another bullet.

The cutting edge is like the cutting part in front of the drill bit. The spiral groove is not deep, just a little guiding groove, which helps the drilled metal to come out of the groove. Luo Zheng looked at the groove and pondered for a moment, then suggested: "Bullet The head is not big, and the two cutting edges exert force at the same time. It is not a big problem to drill through the metal. The spiral groove is too deep, and the metal is too shallow, and the air resistance is large. You need to try it slowly. If you can, you might as well make it. With three blades and an extra spiral groove row of metal, does it have stronger penetrating power? Of course, you are experts, for offensive reference. In addition, I want to name this bullet the Dragon Tooth Bullet to commemorate our former Dragon Tooth Squadron number, okay?"

"No problem, three blades?" Dongfang Ling agreed and began to think deeply.
