All I use is the Handloads.com on-line Ballistic Calculator.

It's pretty basic, but simple is all I need. My operating system is Vista, which has a "Snipping Tool" as its screen capture feature. I use the snipping tool to save the chart produced by the calculator to a picture file. (Sample below) The notation in
blue on the upper left hand corner of the chart was added with "Paint" after the snip picture file was saved.
