It works fine on a well used gun that is abandoned after the crime was my point jun.
Don't work at all on mostly new firearms

with every shot forensics tend to change slightly based on wear imparted by use. Trying to fingerprint new guns by shell casings is fantasy...few hundred rounds later the ejected casings will have different markings on them then the cases cataloged when brand new
