I have been shopping for Sierra's Ballistic program. On Ebay they have what appears to be two versions. One is a 702 at $52.60.
The other is a 701 at $34.01, it has a label on the package that states upgrades are available.
Has anyone had experience with this programs?
Perhaps a similar program that's a better price or one that same price but a better program?

I'm not sure what it is that the Sierra program might do for you that this free one does not, but this one does everything I want or need: http://www.jbmballistics.com/cgi-bin/jbmtraj-5.1.cgi

No way in heck I'd pay for a program when the jb's are available for free.

As Stoencreek said can't imagine what you need theses don't cover.

The Sierra software is external ballistics only just like the free stuff above. The difference between the 701 and 702 is the 702 includes a load manual (printed I think).

Handloads.com has some nice stuff to for free.

I'll check out the programs you suggest.
Thanks
