Bio-explosive Ammunition

These specially modified shurikens contain a potent venom which overloads the target's circulatory system, causing blood vessels to violently erupt. Bio-explosive ammunition may only be used with a shuriken pistol (and is paid for in addition to the pistol). Except where noted, the normal rules for a shuriken pistol apply. The weapon does not have a Strength as such, and always wounds a victim on a D6 roll of 2+. Targets slain by the bio-explosive ammunition explode! Place a blast marker centred on the exploding model and roll to hit other models under the template using the rules for blast weapons. The attacks have a Strength equal to the exploding model's Toughness, and an AP value equal to the victim's saving throw (i.e. models hit by an exploding Space Marine would take a S4 hit with AP 3). Any squad which suffers a casualty from a bio-explosive ammunition must pass a morale check at the end of the shooting phase.
