[The Outsider]

All of you have overlooked a valuable source of ammunition: kobolds! Lightweight, aerodynamic (it's those ears), and in plentiful supply. We here at Firewine Industries suggest that you try a quiver(ing mass) of kobolds sometime. You'll notice that they can be thrown much quicker (and, possibly, further).

Additionally, kobolds are amongst the ranks of your foes, as opposed to drawing upon your shorter allies as ammunition. We feel that this is a viable solution to your tossing problems.
