PUBG video games become so much popular in my country. PUBG is a game where you have to fight other players with the gun-like weapon to become the last survivor. Out of curiosity, I also tried this game. Actually, I don’t like video games too much, but playing PUBG games turns out to be fun and it can train my focus to win the competition. Combat in this PUBG games is like in most shooter games, you shoot the enemies to make them down. Spent hours of playing this game somehow made me think that shooting bullet is an easy thing to do. I can scroll through the single fire, burst fire, or auto fire when shooting guns to eliminate enemies.
But then I realized that the reality is completely different. Professional soldiers need long-long hours of practice to mastering shooting skills. In reality, shooting accuracy is affected by many factors. Not only the precision of seeing the target location that matters, but also the bullet travel itself. The flight path of the bullet is called Bullet Trajectory. Because the bullet travels too fast, we just cannot actually see its curved trajectory. We can simply imagine by throwing a ball in the air and watching it come down. This curved flight path is affected by several following factors:
Gravity force causes objects to fall to the ground, including the bullet. It will pull the bullet down rather than it travels forward. We should consider this gravity force when shooting the target at a certain high. The further target distance the more getting down the bullet will hit the target.
- Weight of the bullet
Since gravity force depends on mass, the selection of the bullet weight is also important to consider. The more massive an object is, the stronger its gravitational force. For example, bullets with 12 mm size have different flight pattern than 5 mm size.
- Air resistance
This is the most important factor in determining the bullet trajectory because air molecules can hinder bullet movement from traveling fast. Bullet without its high speed is just useless. When you shot a bullet in the air, the air molecules (nitrogen, oxygen, water vapor) can inhibit the bullet speed by making friction force. The more molecules, the greater the friction (drag) produced. The total amount of drag is determined by bullet speed, ballistic coefficient, and air density (also depends on atmospheric pressure, temperature, and humidity).
In the case of the underwater situation, the water resistance is much denser than air. Making the standard bullet lose its speed shortly after the bullet came out of the rifles. Then supercavitating bullet (underwater bullet) is developed to overcome this situation. Supercavitating bullet from Duretek company has best designed to reduce water resistance effect in its bullet trajectory.
By used high-density material in the front and low-density material in the rear, resulting GP bullet can reduce the water drag and air resistance. Reduce the yaw angle and it tends to make a more straight path. GP bullet also has various type from 5.56mm, 7.62mm, 9mm, and 12.7mm size are available.
