Using your AccuScope MOA Scope Sighting Chart

Safe Use of AccuScope

Before using AccuScope, thoroughly read and understand your scope and firearm owner's manuals. Also prior to using AccuScope, thoroughly read and understand all information and instructions on the front, back and sliding insert card of AccuScope.

General Scope Information

Most scopes use either a set of cross-hairs or a dot as the mechanism to precisely air your firearm at a target. Scopes usually have two adjustment dials: the elevation adjustment dial and the windage adjustment dial. Both adjustment dials are usually protected by dial caps. Below is a diagram of a typical scope identifying the locations of the adjustment dials. Refer to your scope owner's manual for the exact locations of your scope's adjustment dials. Refer to your scope owner's manual to determine the correct direction to rotate each adjustment dial to achieve scope accuracy.

Minute of Angle (MOA) is critical to sighting in your scope. MOA mathematical concepts were used to develop AccuScope is your scope's MOA number. The MOA information is printed on the dials, on the dial caps, or in your scope owner's manual. The diagram below illustrates a basic 1/8 MOA adjustment dial. AccuScope determines the number of adjustment dial increments or "clicks" to rotate your scope's elevation adjustment dial or windage adjustment dial to accurately sight in your scope. Refer to your scope owner's manual to determine the correct direction to rotate each adjustment dial to achieve scope accuracy.

For the above EXAMPLES,the 1/4 MOA dial has 32 division lines or "clicks", the 1/2 MOA dial has 16 division lines or "clicks" and the 1/8 MOA dial has 64 division lines or "clicks". Due to numerous scope manufacturers, your scope's adjustment dial configuration may vary.

AccuScope Instructions

  1. Determine the shooting distance in yards.
  2. Fire a three shot group aiming at target center.
  3. Mark the center point of the three shot group on the target.
  4. Locate the ruler on the side of AccuScope.
  5. Measure the elevation distance and the windage distance (both in inches). For elevation distance, measure the vertical distance up or down from the center point of the three shot group to the horizontal line of the target center. For windage distance, measure the horizontal line of the target from the center point of the three shot group to the vertical line of the target center. (If the center point of the three shot group is located on either horizontal or vertical target center line, then, respectively, no elevation distance or windage distance adjustment is needed.)
  6. Determine the MOA of your scope.
  7. Locate the DISTANCE OFF-CENTER A window. Move AccuScope's sliding insert card until the elevation distance number you determined is aligned with your scope's MOA number B. Once aligned, do not move the sliding insert card before you complete Step 8.
  8. Locate the SHOOTING DISTANCE C . Directly below your shooting distance number, located in the SCOPE DIAL ADJUSTMENT D window, is the number of adjustment dial increments or "clicks" to rotate the elevation adjustment dial.
  9. With elevation adjustment completed, repeat Step 7 and Step 8 for the windage distance.

AccuScope Example

For the target shown, the elevation distance is 1 inch and the windage distance is 2 inches. The scope's MOA is 1/8, and the shooting distance is 50 yards. As such, the number of clicks to rotate the elevation adjustment dial is sixteen (16). For the windage adjustment dial, it is thirty-two (32) clicks.
