Unusual malfunction .30 Luger case

Earlier this week at the range, I was testing a recently acquired 1906 Model Parabellum "shooter", .30 Luger caliber. All went well for perhaps 20 rounds of Prvi Partizan ammo. I then tried Fiocchi (one round in the magazine). Three rounds fired OK but would not push the toggle back far enough to hold open. I then switched back to the Prvi but the pistol would not chamber the round. Upon inspection I discovered the last .30 Luger Fiocchi round had irregularly sheared off and not extracted. A good push with a cleaning rod and patch from the muzzle end, and it came out.

The photo shows the sheared round and a healthy Fiocchi round from the same box for comparison.

The pistol and extractor appear fine. The teaching of the experiment is that the pistol prefers Prvi ammo, but I'm wondering what could cause such a malfunction?
