A guide that I use was told to me by an old timer that has hunted many elk. He said that if the brow tines are within a couple of inches of his nose, and you can draw an imaginary line from the tip of the brow tine to the 4th tine, and the 2nd and 3rd touch that line, and his rack is wider than his body, then the bull should score 350 or more, but I would maybe go a little on the conservative side in the field.
