It is a little vague. I would assume that it DOES use up a daily Bomb, and you can apply whatever effects you want/have to it, as if you had thrown it.
The main point of the Discovery is "shoot a Bomb from my Bow/X-Bow/Gun".
This let's you add the weapon's accuracy bonus to the attack roll, and you get to use the weapon's range increment, instead of the puny 20ft range of a thrown Bomb.
