Comparing Groups - Target Overlay

Lapua40X

Sometimes it's a challenge to compare one shot group with another when they're side by side. Techniques I've used for a long time included measuring with calipers and various other methods. Now I'm using another method which I find gives me more useful information.
The two groups in the pictures are five shot groups at 100 yards (.284 Winchester) that measure just under .5 MOA. I wouldn't call either of them particularly remarkable but they told me a lot about how the load was working and how the shooter was working.

If you look at them side by side you will probably miss the fact that both, except for one errant round, are essentially the same. Overlaying target A with target B, and vis versa, provided with what I believe to be more meaningful data.

Yeah, sometimes I staple fresh targets directly over top of the older ones so your bottom target will show the "aggregate" when you're done.

Have you tried using OnTarget software?

Unfortunately, most software is written for Windows and/or Mac. I run Linux and very few Windows/Mac programs will run very well, if at all, with Linux. I use "Wine" to install most Windows software but OnTarget is difficult to manipulate (at least for me) so I've pretty much abandoned trying to make it work.

Not sure I follow that. Can't you run a Wintel VM on your Linux box and then run the Windows software on that?

I have OnTarget installed ... the OS screams and hisses (figuratively speaking) when I run it but it does seem to want to function. Is there a tutorial on how to use OnTarget?
 
Well done. I've subscribed to the full version of OnTarget. Basically I input from my scanner, then start a new group and input bullet holes. It takes a bit of getting used to.
