Spent primer separation in brass?
Starline .38 Special brass used in Cowboy Action Shooting. I don't always get all of my brass back after a stage and sometimes I end up with someone elses brass.
Regardless, the loads are almost always minimum power/pressure.
While depriming/resizing, nothing felt amiss. Then the new primer wouldn't seat. Using a Dillon 550.
Ran the brass back into the die to pop the partially seated primer out and found this.

I was not able to pry out whatever is left.
Any ideas?
