    WOW!! Great find. Thanks. :D

    I just compared it's data vs. PointBlank's data, and it is identical except for time of bullet flight, which was 0.002 seconds faster on PointBlank for a .223 @ 300 yards. :rolleyes:

    Everything else is equal. Pretty much every free ballistics program I've used on the net puts out the same data. This spreadsheet is so close to pointblank, there is no doubt they are using the exact same formula. 0.002 difference on 1 catagory is a the difference of precision used in one of the constants within an equation.

    I've never bought a ballistics calculator (why buy that which is available for free?) do I don't know if they are any better. But we're talking physics here, and these equations aren't any sort of top-secret info that only Sierra or others have.

    +1. And thanks; this one is so simple even I can use it.
