A few days ago, NovaHammer asked if you can fire for effect with a sling.
OF COURSE everyone said... shotslings!
...but then I started thinking (which is always dangerous):
https://youtu.be/QYsjzYqgSykAnd there's your answer NovaHammer. Fire for effect is not plausible with a normal sling, but it is maybe plausible with multiple slings!
Plausible at least at ~10 yards, that is. The ammo stayed surprisingly close together, so now I really want to try this at longer distances! Also, this could be optimized more by using exactly identical slings instead of "roughly identical" ones, etc.
