h/t to Knowledge Weighs Nothing.
The Mighty Herr Sprave demonstrates his almost-perfected Rambone slingshot modified to shoot arrows. A 58-lb draw weight on such a compact system is quite impressive.
I like bows for preppers because they are quiet. I usually hunt with my old Bear compound. I'm working on a couple of small primitive bows, just to play with. Archery equipment, even with a take-down recurve, is fairly bulky. Jörg's compact delivery system eliminates a lot of the bulk and weight. You still have to deal with arrows. As the KWN guy points out, you could carry just heads and fletching and make arrows. I think I'd want at least three or four ready to use, though.
It's just plain cool.
