Internal Ballistics

Internal ballistics is the study of how a firearm's ammunition behaves inside the barrel from the moment the primer ignites until the bullet exits. It involves understanding how the combustion of gunpowder generates pressure, how that pressure pushes the bullet forward, and how factors like barrel length and ammunition quality influence velocity and accuracy. Essentially, it’s about the physics and chemistry happening within the firearm before the projectile leaves the barrel, affecting its speed, stability, and precision.
