Re: Software/Vista/etc
I am the developer of BulletFlight. Here is what I believe BulletFlight does better:
1. The calculations are much more accurate. I ran a comparison test, and compared to JBM, an accurate numeral solver, BulletFlight had something like 50 times less percent error difference for each point averaged from 100-2000 yards every 25 yards for a 175 M118LR .308. This is a fundamental. If you don't have this, you have nothing.
2. It has a profile system so you can configure your rifle/scope and those settings live on.
3. The bullet database and BC input are in the proper military ICAO format. Ballistic is in the civilian Metro format.
4. It will calculate actual BCs. Demanding users need this.
5. It has metric and imperial units visible at the same time, without having to change it in an option.
6. You do not need to exit the program and go to the iPhone settings to change options.
7. It gives output directly in scope clicks and other units at the same time.
8. It has a more advanced atmospheric system and does not use that public-domain model.
9. Sight-in weather is factored in and normalizes the zero.
10. It computes bullet stability with a more advanced/modern formula than Greenhil.
11. It does spin drift.
12. It does Coriolis.
13. The table units don't scroll off the screen.
I own both. Ballistic is a fine program of its type (general purpose ballistic table maker). But overall, and for field use, I see no comparison.

I think what is happening here is people buy a program and then defend their purchase religiously.
