Re: ballistic programs
Nightforce is a repackaged version of Exbal. It can be found here:

And both it and the Nightforce version work with any scope.
However, there's also this one, online and free:

Re: ballistic programs
The very best ballistic program on the market for your laptop is the RSI Ballistic Lab. Except for JBM's online, RSI is one of the few ballistic programs using the same ballistic models used by the US Army developed at the Aberdeen Proving grounds. It also has ballistic modeling tools no other programs offer
Bryan Litz's new ballistic program and book is also very good I hear. He's a creative ballistic genius and head ballistic technician at Berger Bullets. I’ve just been too busy to remember or actually want to order his new book and ballistic program. I know if I order it I’ll spend days trying to reverse engineer his ballistic calculations and that’s time I don’t currently have.
I’ve read that his program is still a work in progress, is very accurate and with a large updated ballistic library but lacks some tools other programs have. Below is his link

Hope it helps

Re: ballistic programs
Mike,
Check your email. I sent you something that you can use until you find something better. It is in Excel.

That may be the excel program Dave King and I as well as a few others worked on. It's fairly simple but it works.

Re: ballistic programs
How accurate is any ballistic program? And how would one know?
I have run many ballistic programs. Most do a pretty good job of modeling atmospheric drag.
Every one I have ever run required modifications to get my field shooting data to match the predictions of the program. Most programs lack an explicit mechanism for that, and the primary modifications are modifying the BC and/or the muzzle velocity.
In addition, a user who expects accuracy from a ballistic program must ensure that the program has good data. That includes, but is not limited to:
1. Good muzzle velocity data.
2. Variation of muzzle velocity with temperature.
3. Careful calibration of scope adjustments.
In other words, the accuracy of a ballistic program is at least as dependent on the user as it is on the program.
Having said that, I would expect Sierra's program to model the atmosphere and projectile drag very well.
My current primary choice of ballistic programs is more a function of the feature set and it's usability in the field - I want a program that runs on a PDA - than it is of the "accuracy" of the program.
Bryan Litz's book has good information on use of ballistic programs.
Applied Ballistics for Long Range Shooting
I'm very glad Bryan wrote that book, so I wouldn't have to.

To say "...it works." is a bit of an understatement
Another very good Excel program is the Pesja spreadsheet/program found at jacksonrifles.com
