the most powerfulthe most gleefully insane slingshotsHell
Using a simple, shootable pendulum setup, Sprave and his pal Nathan compared the momentum generated by various handguns from .22s, all the way up to a .44 Magnum. And out of all the hand-cannons tested, the slingshot bested all but one. Now granted, the slingshot’s steel ball ammo is a bit heavier than your average bullet, and not exactly shaped for precision flight, but it holds up pretty well against projectiles with explosions on their side.
So you an safely set aside any notions that slingshots are mere child’s play. They definitely aren’t if you’re building ’em right.
