All deer get 4 mass measurements. 10 pointers will get 1-2 inches more from the h-4 measurements because antlers are thicker between tines then they are half way to the tip of the beam. 10 pointers of similar size to an 8 pointer usually have 6-10 inches more depending on the length of the g-4s.

What looks more impressive..... a 150 8 point or a 150 10 point?
