Vengeance of Ultramar
From Warhammer 40k - Lexicanum
The Vengeance of Ultramar is an ancient Storm Bolter that was last used during the Tyrannic Wars.[1]
It houses a machine spirit that allows for a dramatically increased rate of fire. Furthermore, though the Storm Bolter fires standard-issue bolts, the matter-reactive substance of each round is altered within its hallowed firing chamber to become bio-reactive. This causes any living material struck by it to explode into vaporous clouds.[1]
