Those fired rounds in sealed envelopes...

[Drail]

Those fired cases are just like the tags on pillows that say "Do not remove under penalty of law!!! Smash them up and throw them away.

 

[LockStocksAndBarrel]

You could reload them, fire them in a different gun and then send them in.

I just keep mine in the case. Not causing any harm or getting in the way in there.

 

[PMY]

I keep them because they usually have a date on them.

For some reason I'm fascinated by a gun's date of manufacture.

 

[MrSmitty]

I throw mine around crime scenes, or schools...........

I love that answers have been all over the place.

That tells me that there's no legal issue I have to deal with, and I can even make a Tinkertoy model with 'em.

 

[jdgdigger]

I just keep the in the case the gun came in behind the padding, right there with the owners manual.

 

[westfork]

i eat them like candy.

 

[Effingham]

i eat them like candy.

I'd think a .45 might plug you up...

 

[jdg0724]

I keep mine in the original case.

Allow me a moment of naivete. If you have the empty case in a bag it means the manufacturer did not send it to the powers that be, meaning you don't live in a state/locale that requires it to help with crime scene weapons identification.

However, is not the bullet, fired from that casing, recovered from the test chamber and forwarded to the FBI (?) along with the serial number of said firearm for their records division?
