Thread: On Target Precision Calculator

Evening everyone.

I was looking at my groups I shot last Sunday out of my new 6.5mm SAUM this afternoon and trying to find a way of measuring group size. While I was looking on google, I came across a neat little program called On Target Precision Calculator. So I downloaded it onto my PC and had a bit of a play around with it.

What it does is enable you to import a picture of your target from your phone (or camera) in JPEG format. Once you have calibrated the target correctly, the program allows you to input bullet holes over the top of your actual shots on the target to give you the exact group size. Believe me, the results you see below are exactly the measurements I got when I measured my target with my digital vernier.

Best of all, the software is free. There is a paid version as well, however the free version is all I need. The link to the software is below, along with a couple of screen shots from my laptop.

I wish they'd do an OSX version.

The interface is absolutely horrendous, but it's about the only free solution I've found. Handy tool, just not very user friendly.

EDIT: It's probably worth noting that I've yet to come across any solution (paid or otherwise) that doesn't have an awful UI. I'd be happy to pay for one with a good interface.

Have happily used it for several years so ended up giving the developer money. Had a few questions which he responded to nicely.
The UI is perfectly OK just "clunky" once you are used to it.
Once your group is plotted it puts a text box below your group with all the info on it.
Text box then appears in printouts. This however may however be what you get by paying his miniscule fee.
Hopefully by giving him a pittance he may enhance the UI.
There is another ap that gives a similar result but cannot remember the name of it.
