The Entropy-Point Round

This heavy 12.7 x 55mm cartridge features a casing of matte-black leaden-brass and a projectile carved from a single shard of refined void-glass. The surface of the bullet is etched with infinitesimal silver runes that seem to pulse with a low, thrumming vibration. When loaded into a compatible firearm, the air around the breach frost-shimmers and smells of ozone and ash.
