A ballistics expert understands the different marks that firearms leave on bullets when they are fired, including the marks of the rifling on a barrel and other striations on the projectile. They may also perform modeling of the scene to identify where a firearm or explosive was used and perform chemical analysis to identify the weapon that was used.

Forensic ballistics is the examination of evidence relating to firearms at a crime scene, including the effects and behavior of projectiles and explosive devices. A forensic ballistics expert matches bullets, fragments, and other evidence with the weapons of alleged suspects or others involved in a case. The importance of being a forensic scientist is being able to explain their findings to a jury during criminal or civil trials.

Cons-

Experts should be prepared to work irregular hours, if necessary, and to travel to crime scenes regardless of the time of day or the weather conditions.

Because of their specialization, forensic ballistics experts may be able to obtain positions with higher salaries than entry-level forensic science technicians. The Bureau of Labor Statistics reported a median salary of $57,850 per year for forensic science technicians as of 2017. Private consultants also perform work on behalf of firearms manufacturers and law firms.
