What is the best ballistic software that can be adjusted? I am going to buy a ppc del axim since I do not have an Iphone or I-pad. I guess the software will have to be small enough to fit on an sd card? Suggestions on this type of setup for hunting? Or should I try to order a custom turret through leupold? I don't have an I-phone or a smart phone. i would rather use a ppc so I can carry a backup battery for long hunts away from electricity. Are there any that will work with a ppc or do i need to invest in a smart phone or i-phone?
