The Oblivion Jacketed Point

A heavy, oversized 12.7 x 55mm cartridge crafted from a matte-black alloy that feels impossibly heavy for its size. The casing is etched with pulsing purple runes that seem to draw light out of the room. The projectile is not lead, but a crystallized sliver of the Far Realm, vibrating with a low, subsonic hum that causes nosebleeds in those standing too close.
