Automatic Slingshots

An automatic slingshot removes the slowest part of shooting one: the gap between shots. A magazine sits above the fork, a spring feeds the next ball down, and a magnetic pouch picks it up as you draw — so the second shot costs you a draw rather than a rummage through your pocket.

These are also called auto-loading, semi-automatic or repeating slingshots. The mechanism is the same: a tube, a spring and a magnet, machined to a tolerance that only works with one ball size. Read the ammunition spec before you buy your steel.
