Let's put it this way, these are microgrenades. They're not the same thing Arny used to level armoured swat team members in the Terminator series. They're a fraction of the size and mass, however based on the ranges and how they compare to current ones, they have drastically increased velocity (the ranges are insane!) so we can assume they're approximately equivalent to riot control bean bags. Treat them as a Gel Round loaded heavy pistol. I would say, roughly, 10S AP 0 at point blank, then apply a -1 DV, +1 AP modifier per increment. This is lethal with some net hits, to reflect getting hit in the centre chest between heart beats (known to kill with riot control rounds) but not usually lethal (because it is comparable to a baseball player getting nailed by a straight drive).
