What a dumb idea. As usually is the case with gun control laws, this law will hurt the ammunition manufacturers and legal users, and have no impact on criminals.
- Vast stockpiles of un-numbered ammunition exist, and will take years to be expended.
- Unless all the other states follow suit, anyone would be able to obtain unmarked ammo by going to a different state.
- Even if all US made ammunition is marked, unmarked ammunition will be smuggled in on the black market, just as cocaine, heroin, and illegal weapons are.
- Serial numbers on guns have not enabled the police to trace weapons from manufacture to criminal reliably, so why would ammunition serial numbers?
