+4" @ 100y would put you up to 4.75" @ 150y, zero @ 270y. It seems silly to me to have your point of impact off of your point of aim by so much at normal hunting ranges. Between 80y & 220y your point of impact would be at least 3" above your point of aim. At 350 yards its down 9"
More sane for the 30-06 would be a +2" @ 100y, that is a 200y zero with 180 gr @ 2700 fps. Between 100 & 230y the bullet is always within 2" of where you aim. At 350y it is 16" low
