A bullet trajectory chart is a chart that calculates the orbit of a bullet fired from a gun or other firearm. The chart is also known as a ballistic trajectory chart.
The trajectory chart helps a person know the details on how his ammunition is firing. The chart also acts as a calculator by determining the flight orbit of a bullet using the shooting framework set by the conditions. With this calculation, a shooter can determine the bullet's drop, weight, energy, trajectory and velocity. The chart is accurate as long as the two variables, initial velocity and ballistic co-efficient, are definite.
