SIGHT IN FORMULA
To determine the correct sight height to correct an elevation problem, multiply the sight radius, in decimals by the elevation error and then divide the results by the distance to the target, in inches.
Sight radius 5 3/4" = 5.75
Shooting 5 inches low
Distance to target 25 feet or 300 inches
5.75 X 5 divided 300 = .09583
The front sight would have to be lowered .096 inch or the rear sight raised that amount (or a combination there of) to raise the point of impact.
Sight radius 4" = 4
Shooting 6 inches low
Distance to target 25 yards or 900 inches
4 X 6 divided 900 = .0266
The front sight would have to be lowered .027 inch or the rear sight raised that amount (or a combination there of) to raise the point of impact.
