I had that happen with some old Dominion .22lr someone gave me. Everything looked fine, cases were clean and stored in an airtight pill bottle lol.
Coincidentally it was also in my Scorpio. The rupture in my case was on the back of the case head where it rests against the breech. Had 2 in a row so the rest got buried. No stuck bullets.
