      Your case has a belly button .

          Is that a mew piece? Could be corrosion that chunked off and cleaned up after tumbling if a used piece.

                              Looks like the beginning of a split? Brass workhardens and becomes brittle after a few reloads.

                                  Maybe it was fired in a pressure gun.
                                  Pressure gun fired cases usually have a hole on the side from the copper crusher or where it was drilled for use with a Piezo sensor.

                                      Looks like a porosity pit in the initial casting or forging process...
                                      Chuck it and move on...
                                      Cheers...

                                          Chucking 12 so far. All Winchester. Interesting. But yes- definitely chuck and move on. Picked up a bunch of marginal brass apparently.

                                                          Here's an interesting defect I found on a brand new Remington 375 H&H case.
