Comparative bullet-lead analysis (CBLA), also known as compositional bullet-lead analysis, is a now discredited and abandoned forensic technique which used chemistry to link crime scene bullets to ones possessed by suspects on the theory that each batch of lead had a unique elemental makeup.

Compositional bullet lead analysis (CBLA) was a method used solely in the US by the FBI Laboratory to compare the content of bullet lead and make an attribution of source (manufacturer, production unit, box of bullets).

The theory was that if a bullet from the crime scene had the same lead composition as a bullet from a box of bullets owned by a suspect, there was physical evidence linking the suspect to the crime scene.

Rifling marks are caused by spiral grooves located inside the gun barrel. These spirals cause the bullet to spin, producing a more stable flight path.

Bullet Casting Alloy consists of 2% tin, 6% antimony and 92% lead - also known as "hardball" bullet casting alloy.

"Lead solid" simply means the bullet is completely made of lead, and isn't hollow or filled with another metal. When most people think of a bullet, they think of a lead solid and usually a round nose, because this is the most popular style and it can be used for pretty much anything.

Bullet - The projectile that is expelled from a rifled firearm (as opposed to slug). Cartridge - A complete unfired round of ammunition consisting of a cartridge case, projectile (bullet), primer and smokeless powder.
