Not sure on the numbers but I know it's around 10% chance to kill per use. I don't even know why I use them personally, I might as well just use Betties since I have like a 30% chance to kill with those.
Bwahahah! Actually I don't really know if I'm any good with them or not. I just tried them and kind of mess around when I use them. My explosives ratio is horrible so I ignore them on my classes quite often.
