Found in a classroom of abandoned school campus
**SOLVED**
Thank you to the many commenters who offered their insights, identifying them as simulation rounds, or "simunation" typically used for law enforcement tactical training.

Found in classroom of abandoned school campus
I am the sole employee of an abandoned school campus where I manage district curriculum stock and store school furniture.
I found these 3 items on the floor in a classroom. The school has frequent break-ins from vandals and homeless, and recently hosted a SWAT and LE K9 training. The metal half looks like a shell casing (if that’s the correct term) and I wonder if these are spent dummy rounds. I have no idea what they’re supposed to look like, so that’s just my ignorant guess.
