Question out of my ignorance. If all I have available is a 100 yard range to zero my scope but I want the zero at 400 yards how is this accomplished?
My ballistic data shows that if the rifle is zeroed at 400 yards then the 168 grain BTHP will be + 9.0 inches at 100 yards.Do I hold the crosshairs +9.0 above bullseye @ 100 yards and adjust scope to this position or do I hold the scope crosshairs on the bullseye and and set the bullet point of impact +9.0 inches above the bullseye center @ 100 yards ? Any helpful info or links would be appreciated.
