Found a cool free ballistics app for Droid…

— Enter all of your gun/cartridge specific info… Also enter your scope make/model (or more specifically your reticle type) and it will not only calculate all ballistic data but also give you a screen shot on holdover, etc…
This attached shot is an example of my .243 with leupold B&C reticle. 315 yard shot with a 7mph 90 degree cross wind. I think the purple “11” is how many horizontal clicks to get the right windage.
FYI… Thought it was cool, potentially handy.
