I've always sighted my 30-06 1 1/2" -2" high at 100 which was used to hunt wide open areas. This year I'm hunting an area where the maximum shot would be 150 yds, but there are a lot of good possibilities deer would pop out in a few places that are 30-50 yds. away. My question is do I keep it where it is or do I sight it in differently? I've never shot this under 50 yds. I'm wondering if at 50 yds. and less the bullet would shoot low. I'm obviously going to shoot at these closer distances at the range, but hate to burn more ammo than I need. Any info would be greatly appreciated.
