After rereading your post, I see now what you probably meant.
Yes, if the barcodes were etched on the cases, that code could be tied to a sale.
Have you watched modern mfg of ammo? It is run in batches. Would you expect one barcode for the whole batch of thousands of rounds? If you insisted on a separate barcode for each box, you would shut down the ammo manufacturing business.
And, what about reloaders, like myself?
And, an easy way around that magic barcode? Revolvers.

As for the batches, I don't know. I suppose it could turn out that two or three people buy ammo with the same bar code in which case the police would have 3 suspects in a crime. I would expect anyone not involved with the crime would have an alibi, maybe even ironclad (if you use a credit card, if you can prove you were hundreds of miles away at the time, and if you have a cell phone on you with geo-tracking, or maybe you were at work at the time, etc. These gang members usually travel hundreds of miles out of the various cities to buy guns, so the odds that two different people who bought the same ammo would be in the same city at the same time is small. Not only so but the streets are filled with cameras that can confirm a person's alibi. Cars are being tracked, that could also confirm it.
