If you lined your 30-06 at 110 yards it will probably shoot low at 50 yards.Here are a few tips to use when lining up your gun.
1.Use the same brand and grain weight of bullets,don't change after lining it up.
2.Use a steady rest or Caldwell Ledsled to hold your gun secure.
3.Shoot 3 times,then see where your groups are and adjust your scope accordingly.
4.Make sure your scope rings and mounts are secure/tight!
5.Let your gun cool down after each groups of 3 shots.
6.Make sure you adjust your up-down and left-right adjustments the right direction.
Do what this guy said. Use a Lead Sled and you should be able to hit bullet holes. I have noticed on some scopes that the 0.25" equals 1 click at 100 yards is not right so just go slow with the adjustments.
