Bullets Ricochet from car body metals

The “lead” bullets angle into the metal surface can be approximated by the first 1/3 of the channeled impression into the surface.  The angle of departure is approximated by the last 1/3 of the channeled impression..  This can be useful when estimating “where from” or perhaps narrowiing the search of where to look.  With copper jacjeted hollow point, this is not necessarily true

The angle that the lead bullet departs the metal may be greater than the angle of entry because of the distortion of the metal which causes a ramping effect that helps elevate the bullet as it leaves the surface.
