Basics Of Ballistics
Ballistics is the science of projectiles and firearms. It covers the behavior of the bullet from the moment it leaves the barrel until it hits the target.
There are three main phases in ballistics:
- Internal Ballistics: The bullet’s behavior inside the barrel.
- External Ballistics: The bullet’s flight path to the target.
- Terminal Ballistics: The bullet’s impact on the target.
Each phase affects the bullet’s performance. Understanding these phases helps shooters make informed decisions.
In the case of the 5.56 NATO round, barrel length primarily influences internal and external ballistics. A longer barrel allows for more complete combustion of the powder. This results in higher bullet velocity and a flatter trajectory.
