Video below, but a law currently being purposed in Pennsylvania would require by 2024 that every bullet has to have its own serial number, with that serial number being both etched into the bullet and inside the case. In addition the serial number on the bullet would be required to be able to survive impact after it is fired. Just to top it off any ammunition that isn’t etched with said serial numbers would be illegal as of Jan 2024. I doubt this will pass but given the stupidity of other states lately who knows. But bills like these do point out how unserious they really are about crime, and are much more interested in just bankrupting the gun industry.
