Slingshots (ie: wrist rockets) are better for squirrel, faster projectile. You need perfectly round projectiles, like marbles, so they don't wobble in flight. And yes, I've eaten squirrel, usually "Squirrel and dumplings". Not bad if the squirrels aren't too gamey, it just takes a lot of squirrels to make a pot. We ate normal food most of the time, but my parents made sure all 7 of us tasted squirrel, turtle, rabbit and lots of deer, dove, quail, duck, lake fish, wild turkey and other game. Most parents don't teach self-sufficiency and basic survival skills, except those that the majority snidely call "rednecks".
And the "wrist rocket" IS technology: the taking of an old concept, and updating it with the most modern materials. You can do some serious damage with one of those.
