What occurs during internal ballistics?

During internal ballistics, the focus is on the events occurring within the firearm from the moment of ignition until the projectile exits the barrel. This encompasses the entire process that happens after the trigger is pulled, including the ignition of the primer, the burning of the propellant, the generation of gas pressure, and the resulting acceleration of the bullet down the barrel. Understanding these processes is crucial for analyzing the efficiency and performance of ammunition and firearms, as they directly influence factors like muzzle velocity and energy transfer.

On the other hand, the analysis of projectile behavior in flight pertains to external ballistics, which examines how various factors affect a projectile once it leaves the barrel. Similarly, the interaction of a projectile with the target relates to terminal ballistics, which looks at the effects and penetration of the projectile upon impact. Lastly, trajectory calculations involve the external ballistics aspects, assessing the flight path of the projectile influenced by environmental factors.
