229. No need to take in existing to have it marked. Manufacturers will mark new ammo.

Sooner or later, the old will be shot, or if it makes people less likely to fire off rounds in order to hoard unmarked rounds, that's okay, too.

The oil companies track every barrel of oil sent by truck, pipeline, or rail using microfiche chips afloat in the oil. Billions of barrels at a time, This is so that when spills occur, we know whose oil it is. I was an inventory specialist for a decade before I started teaching, and the technology is there right now to mark each casing and slug with a unique identifier.

I mean, there are at least 15 billion web pages, each one with a unique identifier. And as usage becomes universal, the marking tech will become negligible in cost.

I promise it's feasible, and I think it's perfectly okay to just start with new; let the old eventually be used up. If anything, law enforcement can use the prospect of unmarked ammo to sting criminals from the get-go.

Thanks for saying that we can do some things. I appreciate that.
