I think James B. hit the nail on the head. Although on paper a rifle in the 30/06 velocity class, with a scope mounted 1.7" above the bore, should be about 3.5" high at 100 yards when sighted in dead on at 25 yards; you might in reality be anywhere from a little low to 8" high at 100 yards. Don't shoot at a deerfurther than100 yards away until you get back to the range to check your 100 yard zero.
