If you are referring to ballistic forensics, then I agree with you, but this is not what is being discussed and certainly not what I was speaking about. This has to do with stamped shell casings
I'm an amateur machinist and I can easily comprehend a mechanism for creating/forging stamped cases. It is a technology that could easily be done on existing weapons.
No, it does not. It has to do with laser etching serial numbers on bullets. The 'finger printing' of shellcases is an entirely different matter. No gunsmith can duplicate or 'forge' either.
Please be accurate with your postings.
