Re: NIghtforce Ballistic software..
If you shoot me your email address, I will send you a simple to use calculator in the Excel format that can be used on a pocket PC with Excel. If this will fit your needs for a portable calculator, then you can have it.
Long range shooting is a process that ends with a result. Once you start to focus on the result (how bad your last shot was, how big the group is going to be, what your buck will score, what your match score is, what place you are in...) then you loose the capacity to focus on the process.
