OnTarget Precision Calculator

This is the original OnTarget program, used to measure and analyze bullet hole groups using an image of your target. Measuring your groups, and calculating precision and accuracy take only a few simple steps.

  • Import the target image and set the scale.
  • Set the target distance and hole size.
  • Create a new group.
  • Shots are added by placing a circle over each hole.
  • Group information is updated as each hole is added.

Group information includes: max spread center-to-center, height and width, mean radius, and offset from point-of-aim. The calculations are based on the center of the bullet holes regardless of bullet caliber. Measurement units are available in Standard/Metric, and MOA/mils.

When measurements are complete, the target information is saved to an OnTarget project file as a permanent record. Group information and point data can be printed out, or exported to an Excel compatible file.
