What is the purpose of a chronograph in ballistics?

The primary purpose of a chronograph in ballistics is to determine bullet velocity. This tool is essential for measuring how fast a bullet travels when it is fired from a firearm. By calculating the velocity, ballisticians can glean critical information about the ammunition's performance, including its energy, trajectory, and potential impact on target behavior.

Understanding the velocity of a bullet is vital for various applications in shooting sports, law enforcement, and military contexts. It helps in making informed decisions regarding bullet selection, load development, and overall accuracy of shots fired. Additionally, knowing the velocity allows for better calculations in long-range shooting, where adjustments must be made for factors such as drop and wind drift.

The other options, while related to different aspects of ballistics, do not fall within the primary function of a chronograph.
