Armor Penetration and Armor resistance.

[Archimedes]

Actually, slings don't work in a linear fashion...lighter ammo doesn't necessarily go farther. I sling fairly regularly and I find that my best weight for range is about 70 grams...lighter ammo drops in range pretty fast, especially under about 40-45 grams. I sling lead, rocks, and cement balls I handroll (and that weigh ~70 grams :twisted: ) and this is true for all of them. Incidentally, lead has three main advantages over rocks: 1-its manufactured, so aerodynamic shape and consistent weight 2- lead is denser, so less surface area to create drag 3- you can use a sling that is specifically made for the ammo...this is a far bigger thing than most people realize. A sling pouch for lead ammo can be very small and shaped for the ammo, increasing accuracy and especially reducing drag on the sling, increasing the release velocity.
