Ever see these..?

Found these today along with one Mercury Dime. I do a lot of shooting but have never seen a shell with these plastic inserts. They say 9mm on the ends and are center fire. Found them in a park where shooting would never be allowed so they have been there for a while..!

Earl43 is correct, however they shoot chaulk not paint.

They shoot a little plastic projectile that is split on the ends and contains a colored liquid soap, washes right out of your gear/clothes. Shot a BUNCH of these over the years...
