By adopting Biasotti and Murdock’s
CMS criteria, it is practicable to make future automated systems
have similar or identical measurement results to the manual
method operating under a comparison microscope. The subjective
procedures of examiners working with comparison microscopes
could then be re-evaluated rapidly for large populations of known
matches and non-matches from a variety of different calibers of
bullet and cartridge types and barrel rifling manufacturing
methods. The CMS criteria can then be validated or revised
accordingly. These automated measurements, which are more
objective, can therefore be used to increase confidence in the
validity of the CMS approach [2] originally developed and practiced
using direct manual comparisons.
From the early 1990s, automated
