37 Facts About Ballistics

What is Ballistics?

Ballistics is the science of projectiles and firearms. It involves studying the motion, behavior, and effects of projectiles, typically bullets, unguided bombs, rockets, or the like. This field is crucial for understanding how different factors influence the trajectory and impact of these objects.

1. 01Ballistics comes from the Greek word "ballein," meaning "to throw."
2. 02Internal ballistics focuses on the processes inside a firearm when a projectile is fired.
3. 03External ballistics studies the projectile's flight from the muzzle to the target.
4. 04Terminal ballistics examines the effects of a projectile when it hits the target.
5. 05Forensic ballistics helps solve crimes by analyzing bullet trajectories and impacts.

Internal Ballistics: The Science Inside the Barrel

Internal ballistics deals with the processes that occur from the moment the firing pin strikes the primer until the projectile exits the barrel. This phase is critical for understanding how different firearms and ammunition types perform.

6. 06Propellant burns inside the cartridge, creating gas that propels the bullet forward.
7. 07Barrel length affects the bullet's velocity; longer barrels generally produce higher speeds.
8. 08Rifling inside the barrel imparts a spin to the bullet, stabilizing its flight.
9. 09Chamber pressure must be carefully controlled to avoid damaging the firearm.
10. 10Bullet seating depth can influence the pressure and velocity of the projectile.

External Ballistics: The Journey Through the Air

External ballistics examines the projectile's flight from the moment it leaves the barrel until it reaches the target. Various factors can influence this phase, making it a complex area of study.

11. 11Gravity constantly pulls the projectile downward, affecting its trajectory.
12. 12Air resistance slows the bullet down, reducing its range and impact.
13. 13Wind can push the projectile off course, requiring shooters to adjust their aim.
14. 14Coriolis effect causes long-range projectiles to curve due to Earth's rotation.
15. 15Ballistic coefficient measures a projectile's ability to overcome air resistance.

Terminal Ballistics: The Impact and Aftermath

Terminal ballistics focuses on what happens when a projectile hits its target. This area is crucial for understanding the effectiveness of different ammunition types and their potential for causing damage.

16. 16Penetration depth is a key factor in a projectile's effectiveness.
17. 17Expansion occurs when hollow-point bullets mushroom upon impact, increasing damage.
18. 18Fragmentation happens when a bullet breaks apart, creating multiple wound channels.
19. 19Hydrostatic shock can cause damage to tissues far from the bullet's path.
20. 20Temporary cavity is the space created by the bullet's passage, which can cause significant injury.

Forensic Ballistics: Solving Crimes with Science

Forensic ballistics applies the principles of ballistics to criminal investigations. By analyzing bullets and cartridge cases, forensic experts can provide crucial evidence in solving crimes.

21. 21Striations are unique marks left on a bullet by the barrel's rifling.
22. 22Firing pin impressions can link a cartridge case to a specific firearm.
23. 23Gunshot residue can indicate if someone recently fired a weapon.
24. 24Trajectory analysis helps reconstruct the events of a shooting.
25. 25Bullet matching involves comparing recovered bullets to test-fired ones from a suspect's firearm.

Historical Milestones in Ballistics
