Grenade rules?

[zozotroll]

I cant find any rules on thier use in either the main book, or pirates. I realize that they are mostly a pirates thing, but other than a listing with range, and damage, there are no rules on thier use.

Am I once again being a dummy, or are there really no rules?

And does anyone have a set? I am looking for burst radius and some form of drift for missing. It just isnt pirates without grenades.
