What Do Forensic Ballistics Experts Do?

Firearms examiners and ballistics experts possess two different, though related, areas of expertise. Firearm examination is concerned with analyzing the characteristics of guns and bullets. For example, firearms examiners may use their skills to identify weapons used to commit a crime. They may be able to determine firearms’ manufacturers, models and caliber – the size of the internal diameter of the gun barrel – based on bullet fragments or shell casings left at the scene of the crime.

Ballistics refers to the science of the mechanics of projectiles. A forensic ballistics expert may be able to figure out the flight path or trajectory of a bullet and determine and probable distance it traveled. The work of ballistics experts can provide valuable insight into criminal investigations, such as suggesting where the shooter was positioned.

Firearms examiners and ballistics experts analyze evidence ranging from the guns themselves to live ammunition and the remnants of spent ammunition, including spent cartridges, shell casings and bullet fragments. They may even examine the wounds sustained by the victim or any clothing the victim was wearing, which may contain traces of chemical residues.

A firearm and ballistics expert may attempt to identify potential suspects through ballistics fingerprinting, identify chemical residues left on clothing or the environment of the crime scene, and identify tool marks – like indentations, abrasions and cuts – on bullets that link the ammunition to a particular firearm. Ballistics experts may also check the data produced by their lab tests against the FBI’s ballistic database or other databases.

Part of the ballistics expert career is making known laboratory findings to law enforcement personnel and the judges and juries in court cases. To communicate their findings, firearm and ballistics experts write detailed reports that investigators use as they chase down leads and try to solve crimes.

The ballistics expert job is an important one in crime labs, because the findings produced by firearms and ballistics examination can be what cracks a case, especially when there were no witnesses to the crime.

When a person charged with the crime goes to trial, firearms and ballistics experts may serve as expert witnesses for the prosecution. The expert testimony they provide can inform jurors of what the science says about the weapon used in the crime and how it is connected to the defendant.

Earn a College Degree

The first step required to become a ballistics expert is to go to college. Although the specialized skills needed for ballistics analysis are taught on the job, a degree is essential to break into the field of forensic sciences. Most ballistics experts have at least a bachelor’s degree in a field that encompasses considerable coursework in science, and some have a master’s degree or even a doctoral degree.

Get Hired as an Entry-Level Forensic Scientist

The next step required to become a forensic ballistics expert is to begin gaining work experience in crime scene investigation and forensic evidence analysis.

You won’t start your career in forensic science as a ballistics expert. Rather, you need to land your first forensic scientist technician role first and then develop your expertise in ballistics through completing firearms identification training programs on the job. This process of learning laboratory specialties through on-the-job training is common not only in the field of firearms examinations and ballistics but among other forensic specialist roles, the United States Bureau of Labor Statistics reported.

This stage of your career is also when you have the opportunity to develop your expertise in forensic ballistics, including analyzing bullet holes and identifying rifling patterns. While you may have the opportunity to take some limited classes related to firearms and ballistics in college, there aren’t degree programs available in ballistics specifically, The Houston Chronicle reported. Forensic ballistics experts gain most of their knowledge of this specialized area of forensic science on the job through hands-on firearms analysis training. As an apprentice in a forensic laboratory, you will have the opportunity to complete firearms forensics training.

Pass a Firearms Analysis Proficiency Exam and Pursue Certification

After finishing firearms analysis training, an aspiring ballistics expert must prove their knowledge and skills in this area of specialty by passing a proficiency exam. Only upon passing this test are ballistics experts considered qualified to work independently and serve as expert witnesses who can testify in court cases.


A forensics ballistic expert may choose to go further in demonstrating their professional proficiency. Experienced forensic specialists in ballistics can pursue professional certification from the Association of Firearm and Tool Mark Examiners (AFTE).
