OnTarget Software Measures Group Sizes from Scan or Photo

Jeffrey Block has created a great new FREE software program, OnTarget, that measures shot groups quickly and precisely. All you need is a photo or scan of your target. The program allows you to set your target distance, and provides caliber-specific tools to precisely mark the center of each shot. Once you’ve marked each bullet hole, Jeff’s OnTarget program automatically calculates group center, maximum group spread (CTC), average distance to center, group width and height, and group offset from point of aim. The program will even measure multiple groups on the same target.

After just a few minutes spent learning the program’s tool buttons, we were able to plot shot groups on a variety of targets with ease. Once you select the target distance and bullet diameter, figuring group size is a simple matter of centering a circle tool over each bullet hole. Then the program “connects the dots” and provides all the info you could want automatically.

The program worked with bullet holes as small as 17 caliber and as large as 50 caliber. It is very precise, but remember that if your target photo was taken at an angle, distorted perspective can cause slight errors in measurement. Therefore, for the ultimate precision, you want to start with a flat scan of the target.

OnTarget Compared to Measuring Manually
We found OnTarget to be especially useful for groups with widely dispersed bullet holes, or very small bullet holes, such as 17 caliber holes. We’ve found that it’s difficult to measure 17-cal group sizes with a standard caliper, because the tool itself obscures the tiny holes. With OnTarget, the program can zoom up your target view, making it much easier to plot the center of each shot. And with a widely dispersed group of shots, the program automatically finds the two most distant shots. You can’t mistakenly pick the wrong pair of shots to measure.

Flash Tutorial Shows How It Works
Jeff created an excellent animated Animated Tutorial demonstrating OnTarget’s functions. It shows how to import a target image or scan, how to set target distance and scale, how to set bullet size and circle each bullet hole, and how to save the marked and measured target. VIEW OnTarget TUTORIAL

MEASURING REAL TARGETS — Actual Examples

Here are examples we created with OnTarget. The first photo shows a 17 Mach 2 target. These tiny 17-cal holes are notoriously hard to measure. With OnTarget, it’s a snap. You just load the target image into the program, zoom in with the controls, and then click on the center of the holes. The program automatically calculates group size, displaying measurements in both inches and minutes of angle (MOA)

10-shot Groups? — No Problem
Here’s another target, showing 6mm bullet holes at 600 yards. The first image shows the target image loaded into the program with the ten holes circled in red.

For this target we have used the Aiming Point option. The Aim Point was set at the center of the “X” and the program calculates average distance from the Aim Point. Very cool.

No Scanner Needed
The OnTarget program grabs target scans directly from a flatbed scanner using Microsoft’s Windows Image Acquisition system. But don’t worry if you don’t have a scanner. You can just take a digital photo of your target and OnTarget will import it quickly and easily. To set target scale, a simple tool allows you to mark a known length on the target (such as the diameter of the “X” Ring), and the program will then size the target accordingly. Is OnTarget precise and accurate? Here’s what Forum Member Steve W. says: “I used the extreme spread measurement of a group on one of my 600-yard match targets… as it was officially scored at the match. By clicking the +—+ icon, then clicked the cursor in the centers of the two extreme spread holes, I then entered that value in the reference window. After that it was simple because the bullet placement cursor’s circle was the same size as the black outline of the actual bullet holes on the picture of the target. OnTarget’s measurement came up within .006″ of the official 2.772 inch measurement of the group. That’s pretty darned close; well inside the human judgment of aligning the tips of a micrometer on the bullet holes.”

Bottom Line — Great Program — Download It Today
Jeffrey Block has done a great service for shooters by creating the FREE OnTarget program. It is easy to learn, it functions great, and it can save you time and effort measuring targets. It also lets you easily archive and compare multiple targets produced during load development or rifle testing. You can record ammo type, date, location, weather etc. in note fields accessed by “Group Info” and “Target Info” tabs.

Keep in mind that OnTarget was NOT created to replace existing methods for scoring competition targets. But for all other target measuring purposes it does a great job. Visit Jeff’s website, OnTargetShooting.com, view the tutorial, and check out OnTarget for yourselves.
