Thanks mamlukino, I'll check it out. I do a lot of graphics work on the side and I like to tinker with scaled targets. In the target above, at 100 yards, the bar across the top and right side are both exactly 1 mil while the small squares are .1 mil.

I can't shoot from my house but there is a space where I can snap in out to about 60 yards without alarming the neighbors. I randomize sizes of various shapes and put them out and mil them to range for simulated distance. Was considering writing a training app for this but, like everything else, its about the time and money you have to spend.
