    Might be a silly question, but I'm somewhat curious what you guys think would happen if you dropped say a 9mm cartridge in a vat of liquid nitrogen.

    Note: as curious as I might be - if you happen to have liquid nitrogen somehow, don't try this out just to satisfy my curiosity. Not worth whatever might happen.

    I'm guessing it would get--well--colder.

    Unless of course you were dropping it into liquid nitrogen immediately after taking it out of liquid helium. Then, of course, it would get warmer.

    So in conclusion, I would say the cartridge would either get colder or warmer--depending.

    Nothing except the bullet and primer might loosen due to differential thermal stress.

    It would get very, very, very cold.:confused:

    sorry to dissapoint

    but nothing, other then it might not fire. The mythbusters did it when testing the "ice bullet" myth. I think that they got low velocity, but nothing crazy.

    Oh, and I think you need a comma in that sentence. :D

    interesting.

    I'll have to watch that episode somehow. Is it out on DVD perhaps?

    I was more wondering if it would go off from compression? I figured the metal would contract and the primer would get squashed and go off..... after that I was out of ideas.

    Don't know why I even thought about it, but it had me wondering.

    It might loosen the bullet if the lead contracted more than the brass case, and even more likely with a steel case.

    There also needs to be a period on that sentence;)

    The primer, and the pellet inside, would shrink too, so that wouldn't happen. And when you prime a round, you're actually compressing the compound a bit, and that doesn't set it off. Sudden shock or heat is needed for that.

    More than likely it would be like glass and shatter when dropped on a hard surface I doubt that the powder would detonate.

    Next time I do a "line freeze" at work I will post results. Might be a while, I only do maybe 2 a year.

    Not likely. Metals are resilient to quite low temps, especially copper alloys.

    Definitely don't put your tongue on it.

    Now the real question--will this increase the reloadable life of the case after thawing.

    Most likely, what would happen is that the LN2 would get inside the case and when you returned it to room temp it would expand and pop the bullet and/or primer out of the case. Other than that, nothing spectacular.

    Make sure it's wearing a padded bra, for starters...
