     Hello, I am Casey Puyleart, a Junior at Bonners Ferry High
School.  I have previously sent messages concerning hydrogen cars,
and cryogenics.  I enjoy using the K12 system, and find it
interesting to read replies to the messages I send, and I learn
something new every time that I log on.
     The topic of this message is ballistics, such as those used in
police departments to trace weapons used in various crimes.  I
would like to know the steps and the processes used in ballistics
tracing.  What types of tests do they use?  Do they test the
chemicals in the bullet, and shell (if found), to trace the weapon
to certain manufacturers?  I have heard that they use the pattern
of scratches and disfigurations on both the bullet and the shell to
trace it to a certain weapon, but that the weapon must be found in
order to compare the bullet found at the scene to a bullet fired
from the suspected weapon.  Is this true?  Also, does the testing
of a suspect's hand to indicate if they have held, or fired, a gun
recently classify under ballistics, or is this an entirely
different field of investigation.
     If anyone has any information on the procedures involved in
ballistics tracing, or knows the answers tomy questions, please
reply.  Thanks.
