Title: List of bullet ballistics
Introduction:
Bullet ballistics is a crucial discipline in modern shooting sports and the military. The ballistic coefficient of a bullet is a key parameter for evaluating the performance of a bullet, and it is of great significance for shooting enthusiasts, military personnel, and ballistics researchers to understand the ballistic coefficient of various bullets. This article will introduce the "List of Bullet Ballistic Coefficients" to help readers better understand the performance characteristics of various types of bullets.
1. Overview of bullet ballistics:
BulletBallistic Coefficient (BC) refers to the ratio of the drag experienced by a bullet to its mass when it flies in the air. This coefficient reflects the ability of the bullet to fly through the air, as well as the efficiency of the kinetic energy transfer of the bullet when it hits the target. In general, the higher the ballistic coefficient, the higher the flight stability and terminal kinetic energy transfer efficiency of the bullet.
2. List of ballistic coefficients of common bullets:
1. Pistol Bullets:
(1) 9mm Parabellum: The BC value is low, which is suitable for close-range shooting.
(2) 45ACP: It has a good BC value, suitable for medium and close shooting.
2. Rifle Bullets:
(1) 5.56×45mm NATO: It has a high muzzle velocity and a good BC value, which is suitable for medium-distance shooting.
(2) 7.62×39mm: It has great lethality and moderate BC value.
(3) 7.62×51mmNATO (full-size version): With a high BC value, it is suitable for long-distance shooting.
(4).308Winchester: Widely used in hunting and shooting competitions, with excellent BC value.
3. Bow and arrow ammunition:
(1) Long arrows: The BC value depends on the shape, weight, and material of the arrow, and long arrows usually have a high BC value.
(2) Composite arrow: made of high-tech materials such as carbon fiber, with a high BC value.
3. Factors affecting the ballistic coefficient of bullets:
1. Bullet shape: The streamlined design of the bullet has a lower air resistance, which increases the BC value.
2. Bullet mass: Bullets with higher mass have higher momentum, which is conducive to increasing the BC value.
3. Bullet material: Bullets with high material density have a higher BC value.
4. Shooting angle: The shooting angle has an impact on the flight trajectory and BC value of the bullet.
4. How to choose the right bullet:
When choosing a bullet, it is necessary to consider factors such as the actual use, the type of target, and the shooting distance. For example, you can choose a bullet with a lower BC value for close-range shooting, while a bullet with a higher BC value for long-range shooting. In addition, performance parameters such as the lethality and penetration of the bullet need to be considered.
Epilogue:
This article presents a list of bullet ballistic coefficients, including BC values and influencing factors for common types such as pistol bullets, rifle bullets, and bow and arrow ammunition. Knowing this information can help shooting enthusiasts, military personnel, and ballistics researchers to choose the right bullet to improve shooting accuracy and combat effectiveness. With the development of technology, there may be more high-performance bullets in the future, and we will continue to monitor the development of this field.
