My parents have my brother's flag.
Having worked funeral details when I was in, typically you aren't receiving the spent blank casings from the actual firing at the funeral. We would have spent live casings that we would polish to place in the folded flag prior to presentation to the family. Keep in mind the presentation of the flag occurs after TAPS is played and the firing team are normally a distance from the flag detail.
Being on those details was a sobering feeling that I'll never forget!
