A sling hurls lead bullets. It doesn’t shoot as far as a crossbow, nor is it as powerful as a bow, but it’s cheap and easy to improvise from common materials. Druids and halflings favour slings. Your Strength modifier applies to damage rolls when you use a sling, just as it does for thrown weapons. You can fire, but not load, a sling with one hand. Loading a sling is a move action that requires two hands and provokes attacks of opportunity.
You can hurl ordinary stones with a sling, but stones are not as dense or as round as bullets. Thus, such an attack deals damage as if the weapon were designed for a creature one size category smaller than you (for instance, 1d3 instead of 1d4 or 1d2 instead of 1d3), and you take a -1 penalty on attack rolls.
