Watching a press conference by law enforcement officials investigating
the Texas church shootings.

They just said that a number of expended rounds have been recovered that
will be sent somewhere that maintains a ballistics database to see if
the rifle used had been previously used in any other shootings or crimes.

So, contrary to some of the discussions we've had here in the past, it
seems there *is* a data base maintained of the unique markings on the
rounds fired from a particular firearm.

I think you're referring to the Maryland requirement that a shell casing be provided the state for
every gun sold in the state. Here a while back the state found that of the thousands of shell
casings sent in, not one had ever been useful in the solving of a crime. I think they stopped the
requirement.

I'm thinking a 'ballistics database' as used above might be a database of casings or bullets that
have been recovered from a crime scene.
