Procedure

Microscopic comparison of
two casts of fired bullet surfaces

There are several recognized brands of appropriate casting material for toolmarks, including Mikrosil™, Coe-Flex™, and Dip-Pak™, among others.

These can accurately replicate the microscopic detail on the surfaces of fired bullets. These products are available in a number of colors.

The procedure for casting the surface of a bullet is as follows:

Mix the components of the casting material until the mixture begins to harden.
Apply the mixture to the surface of the fired bullet and allowed to completely harden.
Remove the cast when it has hardened.
