    What you are describing is a cartridge case not a bullet case.
    Bullets don't have cases, they have jackets. A cartridge consist of
    a bullet, a case, a primer and the propellant. The case, which
    usually is brass, is that part of the cartridge containing the
    powder and primer and into which the bullet is inserted. Most
    bullets have a lead core which is inside a copper alloy shell called
    a jacket. Many  bullets are designed so that  they undergo a
    controlled expansion when they hit something, resulting in  the core
    flattening and expanding while the copper jacket splits in several
    more or less evenly spaced longitudinal strips and curls back on
    itself. This is called "mushrooming", since the end result looks
    kinda like a mushroom when you look at it from the front. It also
    looks kinda like a split seed pod of some sort. As for the perceived
    hazard this presents to the wearer, about the only dire consequences
    of wearing it as a piece of jewelry is the dirty looking  smear
    which would develop if the lead part rubbed against skin or
    clothing.
