"When the gun is fired, the bullet casing would be automatically inscribed with the firearm's serial number..."
The legislators and backers of the bill want the gun companies to R&D the technology and pay for its implementation. Sounds like an unfunded mandate.
Crazy Law.
it is not only expensive, it is PHYSICALLY IMPOSSIBLE.
nothing precise enough and tunable enough to create such "microstamping" of UNIQUE SERIAL NUMBERS or bar codes is robust enough to survive more than a very few shots, if any.
On the surface, that may be what these laws appear to attempt, however, their actual intent is to simply drive any firearm accessories necessary to shoot out of California. These are nothing more than back door, ersatz, gun confiscation laws by making a legal economic ban on ammunition.
Unless these laws can be found to violate the commerce clause.
If Arnold has any sense of business at al, he will veto this madness.
Reloaded range brass is going to be covered with inscriptions. Asinine. Steel cased ammo will probably damage the inscribing surfaces. Aluminum casings used a single time are probably the only viable approach.
Getting replacement barrels and firing pins from a manufacturer might take weeks.
By making barrel rifling correspond to a numerical system by guaging width/depth proportions, it'd be theoretically much easier to make barrel rifle inscription work more reliably than would be a casing stamp or bullet number.
