How do you line up a scope?

the easiest way to line up a scope is set a target 25 yards in front of you. get the gun stable and shoot. If you have it centered at 25 yards, do to 50 yards. Depending on the caliber, you will want to do this at 50 yard settings up to the distance you are comfortable shooting. Now, the only thing you want to change to line your scope is the horizontal, or windage. On most centerfire calibers, if you are dead-on at 25 yards, you will be very close to the same at 200 yards. The cartride will start rising after 25 and will fall backt to "about" the same at 200. The horizontal(windage) IS REALLY THE MOST IMPORTANT SETTING AFTER THE INITIAL 25 YARD SETTING.
