Great minds think alike. :-)
The stupid politicians and movie actors talk about microstamping the "shell casings," which do not exist in ammunition parlance. If you asked them what a primer is, they'd scream: "racist"!
As far as I'm concerned, anyone who has never reloaded ammunition should refrain from making public comments on the topic of ammunition.
As an aside, I put this graphic together for educational purposes for those who think they're firearms experts.
Brass casings make for very tough sausages.
