What are the three phases of ballistics?

The correct answer identifies the three distinct phases of ballistics, which are internal, external, and terminal.

Internal ballistics refers to the processes that occur inside the firearm from the moment the cartridge is ignited until the projectile exits the muzzle. This includes the combustion of the gunpowder and the resultant pressure that propels the bullet down the barrel. Understanding internal ballistics is crucial for assessing how ammunition performs in various conditions.

External ballistics describes the behavior of the projectile once it leaves the muzzle and travels through the air toward the target. This phase involves factors such as bullet stability, air resistance, gravity, and environmental conditions. Analyzing external ballistics is essential for accurate shooting at various distances, as it helps in determining the trajectory of the bullet.

Terminal ballistics focuses on what happens when the projectile reaches the target. This includes the bullet's effectiveness in terms of penetration, expansion, and the damage it causes to the target. Terminal ballistics is critical for evaluating how different ammunition types will perform against various targets, whether in combat or hunting scenarios.

By understanding all three phases of ballistics, shooters can improve their marksmanship, make informed decisions about ammunition choices, and enhance their overall effectiveness in a variety of situations.
