I've had great success racking by doing the following:
Put the head ball on the spot (or usually the divot that has formed on the spot area), make the rack just contact the head ball on both sides of the ball, fill the rest of the balls in behind it, remove the rack. Assuming the balls are ll the same size the rack is generally quite snug.
