Sevens really hit the nail on the head here:
"Across different calibers with different bullets (from different manufacturers) but more so...with particular head stamps, I have found some occasions where it's DAMN difficult to get the amount of case mouth tension you absolutely need.

Head stamps do matter when trying to get a handle on a problem like this. If you are using a scattered handful of 12 different, don't be shocked when you have a half dozen different results. My experience has taught me that this is FACT, regardless of what anyone else might offer."

And definitely don't fire those rounds due to increased pressure if the bullet jams into the case!
