Open sight adjustment
After firing a number of shots, check to see where the bullets are grouping on your target. Adjust your firearm’s sights if the shots are not in the center of the target. With an open sight, remember to move the rear sight in the same direction you want the shots to move on the target.
Telescopic sight adjustmentAdjust a telescopic sight by using the dials on the top and side of the sight; these adjustments can help you compensate for wind or inaccuracies.
The elevation (up and down) is usually on the top and affects the bullet's point of impact vertically. The windage is usually on the right side of the scope and affects the bullet's point of impact horizontally (left and right).
If the bullet needs to go towards the top of the target, adjust the elevation dial in the same direction (as indicated on the dial).
If the bullet needs to go towards the right side of the target, adjust the windage dial in the same direction (as indicated on the dial).
