I'm not about to shoot a 30-06 at a grouse while there could be elk around. A folding slingshot can work very well on grouse but with my aim, I have to carry 2lb of ball bearings to have even a slight chance of getting one. Most of them don't have the patience to wait around while I shoot 20 ball bearings at them.
