Sight Adjustments at 25 Yards - Revere's Riders



KNOWN DISTANCE INTROSight Adjustments at 25 YardsIdentify the group and its center.Identify how many inches you would like your group to move up or down (elevation) and how many inches you would like your group to move left or right (windage).Convert inches to MOA; 0.25” @ 25Y = 1 MOADial in Clicks on sights or scopeMost scopes are four clicks per MOAService-style iron sights are often one click per MOASome iron sights may have finer adjustmentsBasic BallisticsThe bullet begins falling as soon as it clears the muzzle. Because the barrel is tilted up slightly, the bullet will rise in relation to horizontal and crosses the line of sight in two spots; up at the near "zero" and back down at the far "zero".Many variables impact this. This chart assumes a 100 yard zero (or 25 yard for rimfire); all values in MOA and provide a rule of thumb.100 Yards200 Yards300 Yards400 Yards500 Yards600 YardsCenterfireLow Sights (308)023344AR-15 (5.56)AR-15 (.223)001222334556Rimfire(22 LR)0 25 Yds0 50 Yds2.5 75 Yds2.5 100 Yds3.5125 Yds3.5150 YdsData on Personal Equipment (“DOPE”)You will need to collect data on where your rifle groups at different ranges.
