Stuck case in chamber

[tobnpr]

Wonder if a small chunk of dry ice dropped into the chamber would shrink the case enough where it would just fall out or be easily pushed out with a tight brush...

Years back I had a head case separation. I didn't ask here which I have read many times on here the same procedure that my smith Dave Bruno told me. 7mm jag, 30 caliber patch and cleaning rod. This was in my first Competition Match barrel, I was bumping the shoulder way to much. Insert, palm the rear of the rod, pull it out fast. It flung that sucker across the room. Presto, works like a charm.
