I load 9mm in fairly large quantities. Most of my brass comes from what I pick up at the range, so naturally, several .380 cases get mixed in. These are found when they go through the expanding step and there is no resistance when they enter the die. Just out of curiosity, though, I loaded a .380 case with all the 9mm. (no powder or primer) Other than expanding, nothing really feels different. It loaded fine. I REALLY like to think I am careful enough to catch this before it gets in the chamber but just like in manufacturing, 99.99% accuracy is not good enough. That's one in 10,000, which does not take that long. Should I examine every case before prep? Or would it be no big deal? Who here has actually done this? I could see it happening with other cartridges too.
