Last night I was thinking about an hypothetical scenario. Say that an old, nice lady has 30+ year old shotshell from her late husband on shelves in her basement (no firearms, just the ammo). Imagine, as it's often the case, that she doesn't have a FAC/PAL.
First question, I realize that there are many factors to consider, especially humidity levels, but what are the chances that these would still fire without a problem? Would it be dangerous to do so or would they simply not fire if damaged by humidity?
Second question, it would be perfectly legal, as a PAL owner, to get them from her, correct?
Third question, if they do not fire correctly, how do I properly dispose of them?
I ask because it's not that uncommon to see these at old ladies' garage sales once in a while. Often for dirt cheap (or free if they are trying to get rid of them).
