remember, for a while now bullets and guns are all the rage in fashion as a way to be 'ironic'
I am on Yahoo Answers and someone is always asking about how to pull a bullet out the case and 'make it safe' to be used as a necklace or ear-ring.
I expect these kids and young adults are getting the ammo by stealing singles and doubles from boxes.
(as far as how I answer such questions I normally reply with:
-even if you 'deactivate' the ammo before making it into jewelry, any place you take that jewelery where you can't take ammo or guns, expect to have it taken and be given the fifth degree and treated as if it were live ammo
-put it in a gun and shoot it, then keep the case and make a dummy bullet
-if you don't have access to a gun, go to the shooting range and simply ask the owner if you can have a few brass cases for $1.00...the vast majority will let you.
-even if you manage to pull the bullet out with a pliers you will probably ding the case all up, and you still have the primer, so you STILL have live ammo. If going to a range to get empty brass is too much of a hassle, just buy premade 'bullet jewelery' rather than risk making your own.
