Things You'll Need
Instructions
Sight in the scope by adjusting the scopes reticle, or crosshairs, to center on the bullet's projected point-of-impact. Your point-of-impact can be determined either by using a laser boresighter or by using live ammunition to determine where you're hitting the target in relation to where you're aiming, and adjusting accordingly. The scope's elevation is adjustable with a dial on top of the scope and the windage (horizontal axis) can be adjusted with a dial on the right side of the scope.
Estimate your range to target by choosing an object of known height in meters that's in close proximity to your target, if not the target itself. Align your scope's horizontal reticle with the bottom of the object and count the number of mil-dots to the top of the object. If the top of your target is between two mil-dots, estimate the percentage of the interval (for example, half-way would read 0.5). Divide the height of your object by the number of mil-dots and multiply by 1,000. As an example, if your target is 3 meters high and your dot count is 2, then your equation would read: (3 ÷ 2) x 1,000 = 1,500. Your range is 1,500 meters.
Set your scope to the target range to compensate for parallax error. Parallax adjustments are usually on the objective bell, at the far end of your scope, or on the left side of your scope next to the reticle adjustment dials.
