If you're not bore sighted ... what I do before I go to the range is in the house, set the rifle up in a gun vice. If you have no gun vice, a simple large cardboard box with a V cut in the two opposite sides will work. Set that up where you can look through the barrel with the breech plug removed, and sight it on something about 13 yards away. Now make sure the scope is good and solid. Now adjust that scope to the same point you were sighting through the bore on with the cross hairs.

Now out on the range start out at 13 yards. Tune it in at that distance. Then move back to 25 yards, and then 50, and finally 100 yards. This way you also get to see how the rifle acts with the projectile you have at the different distances.
