to be on track,

if your truly serious about getting rid of sprues, you could build yourself a shot machine much like was used to make round ball from wire chunks.

basically its a rotating plate that is simply rotated about an axis, the bottom of the plate is set to be the desired ball diameter from the surface, balls are put between plate and surface and as teh plate spins it makes nice round balls.
