    looks like it was too cold at the range... definitely cold enough to cause some shrinkage...

    What the heck would that have even fit in? A 40?

    Trying to imagine what would chamber it and allow the firing pin to set it off. I’d think the base diameter would have needed to be close enough for the extractor to hold it.

    I've never seen one like that. I wonder if that was a lightly loaded 9mm that was fired in a .380 blowback chamber? You would think the disconnector would keep it from firing but some blowbacks I have had will allow the hammer to fall almost a 1/4 of an inch from battery. :eek:

    I've seen 9mm fired in a .40, it doesn't do that.

    A 9mm in .40 will mushroom out at the mouth until it contacts and conforms to the chamber. Usually not 360 degrees around the mouth, only about 1/2 to 3/4 of the circumference, and the base is not damaged at all.


    Could that be a 9mm in a .380 that fired out of battery?

    This is what 9mm in a .40 would look like. I don't remember it being that much shorter, but maybe my memory is bad on that point.
