New Ammo, not really new but need rules Options

[djinni]

the Bolo round fired from a shotgun, instead of using piano wire string microwire between the balls.
proposed ruling:
Bolo microwire
Damage: 8
Armor: -4
Cost: 80¥ (per 10)
Special: there is the chance of losing a limb, a Critical Success on the attack test will result in the loss of a limb if the target takes more boxes of damage than their natural body rating (Bone lacing and Bone density augmentation add their body dice to the body rating)
a Glitch on the resistance test always results in the loss of a limb.
{edit}: added a suggestion on rules for it.
