.22's come apart very easily if you grasp the bullet with a pair of pliers and rock it back and forth and twist it out. Wear thick leather gloves if you wish, and, as always, wear safety glasses. But the chances of it going off are ... well, you'ld have better odds if you go buy a lottery ticket.
Personally, I'd just throw it away without a thought about it. Even if it goes off in a burning trash dump, it won't cause any harm to the attendants.
