Forensic ballistics involves the examination of evidence from firearms that may have been used in a crime. When a bullet is fired from a gun, the gun leaves microscopic marks on the bullet and cartridge case. These marks are like ballistic fingerprints.

However, besides Pb, ammunition includes antimony (Sb), which is added mainly to increase the hardness, whereas arsenic (As) is used to improve the roundness of shot. Some shot types have also contained small amounts (less than 0.3%) of nickel (Ni).

Most pistol bullets are made of a lead-antimony alloy encased in a soft brass or copper-plated soft steel jacket. In rifle and machine-gun bullets, a soft core of lead is encased in a harder jacket of steel or cupronickel. Armour-piercing bullets have a hardened-steel inner core.

How is Ballistic Evidence Used in Court? Any bullets left at the scene of a crime are collected by investigators and analyzed by forensic ballistics experts. These analysts examine rifling in the spent bullet, which can help identify the firearmor at least the type of firearmused in the commission of the crime.

In technical terms, the two basic tools for ballistic investigations are the comparison microscope, which allows comparison and effective analysis of the evidence, and a software program that allows for the ballistic comparison using a system which stores the data and image base of firearms for further comparison in

Most modern bullets are composed primarily of lead with a copper jacket. Most small caliber bullets are made of lead, yes. Not all, but most. Anything pistol caliber up to full size rifle caliber is 95% of the time lead.
