Ejected brass bulged or split?



Not a 1911, but a CZ-24 (.380) that was my grandpa's.
Got it shooting with a spring kit and a LOT of elbow grease. Had to just about pound it apart due to decades of storage with grease that was more like glue!
Do the bulged and split cases mean the barrel is "shot out"? Gun shoots and cycles fine otherwise. I've only shot a box of ammo, should I not shoot it any more? :scratch:
