Which statement about external ballistics is correct?

Which statement about external ballistics is correct?

• A. The study of a projectile's flight after it leaves the muzzle, including gravity, drag, wind, and spin.
• B. The process of aligning sights with the target.
• C. The design of firearm action mechanisms.
• D. The interpretation of terminal wound channel morphology.

Answer: (A)

External ballistics concerns the projectile’s flight after it leaves the muzzle, with gravity, drag, wind, and spin shaping its path. Gravity pulls the bullet downward over distance, drag slows it as it moves through air, wind can push it off course, and spin helps stabilize the bullet's orientation in flight. This combination of factors determines the trajectory from muzzle exit to impact. The other topics are about aiming (sights alignment), firearm action design (internal mechanisms), and terminal wound analysis (terminal ballistics), not the flight path after leaving the muzzle.
