I use ballistic FTE and love it. It even gives you some government load to compare against. You love it if you:
1. Want to visually compare drop between different cartridges and loads
2. Want to compare wind drift between cartridges and loads
3. Simulate loads before you make tgun)he purchase
I have the FTE also and it is a great program.
Loads easy via iTunes and have not had an issue with drops yet. It appears to use the JBM tables.
I had the Nightforce version on my palm and this seem better especially because my phone battery is always charged.
