How to Use This Tool

Select your target from the dropdown, then click on the canvas where your shots impacted. After 3 shots the NRA grouping diagnosis activates automatically. Toggle the NRA Diagnostic tab to see your zone analysis. Toggle the MOA Zeroing tab to calculate exact turret clicks.

Dual-Axis Zeroing Using Real Target Dimensions

Elevation (Y) and Windage (X) offsets are computed from your shot group centroid using each target's physical inch dimensions — no measuring required. The offset in inches feeds directly into the MOA calculator for precise click counts on both axes independently.

Target Physical Dimensions

• DOD A-1000 (8.5 × 11") — Rifle bullseye; aiming point is centre of black disc
• Transtar I (14 × 20") — Green law enforcement silhouette; aiming point is chest scoring zone
• Transtar II (24 × 40") — Blue full-size silhouette; aiming point is torso scoring zone
• DHS SQT (23 × 35") — Homeland Security qualification; aiming point is upper torso zone

MOA Click Reference

1 MOA ≈ 1.047" at 100 yards. A .25 MOA scope moves ~0.026" per click at 100 yds; .5 MOA moves ~0.052"; 1 MOA moves ~0.105". Select the tab matching your scope's turret increment. Switch YDS/M at top right for metric distances.
