Free G7 Ballistic Calculator w/ Feature???

[jrmy_1]

Does anyone know of a freeware G7 BC calculator, preferably an excel spreadsheet, that allows you to input conditions of rifle zero and then compensates for changes due to different day, altitude, etc? Also would like option of Coriolis, Spin Drift, etc. I may just make my own spreadsheet if there's nothing out there. I would like to be able to load it into a BlackBerry.

Thanks!

I got no idea, but I'd be interested if you get one up and running.
