      Golf balls would work.  They are a bit light though for pole sling ammunition, but would work for a demo.  Especially the bright orange driving range type.

      My guess is the bundle of paint balls would have a much higher drag coefficient than a stone or lead shot.  So it wouldn't give very good results when shooting for distance.  It might be possible to start with a very heavy stone, then one lighter, then one lighter.  Shoot each several times to get an average and then extrapolate for a lighter projectile.  Of course there is a point where further reducing the mass of the projectile will not add range and will actually shorten it.  If I just want to do a pole sling demo the pain balls would work.  Alternately I could use something like a dense rubber ball or a rock covered in cloth and talcum powder.  That ought to be easy to spot when it hits. 
      Has anyone ever done a pole sling demo at Pennsic?

      And yes, the range of the Pole Sling should be equal to or greater than that of an Atlatl. Because of the longer arm within the principles of a Fulcrum.

      For those of you who are interested check out the Primitive ways web site good stuff there.
