is be used by lots of guys, to throw rocks at groups of guys, and get the RARE fluke hit. Big deal. I have $5k that says that NOBODY can demo reliable hits on a man target with one, beyond the range at which a good man could do the same thing throwing the same rocks by hand. So why bother? If you have a threat, or need food, ANY risk of missing it, with a rock, is an unacceptable risk. All a sling MIGHT be good for is tossing incendiaries, or throwing a distracting "noisemaker" further than can be done by hand. No need of PRACTICE for such use. You lames can't even shoot a rifle and a pistol worth a hoot, can't fight hand to hand, have no CLUE how to make a good can, etc. Those things are what you'd better work on, not bs like practicing with a sling.
