The big question is what kind of BCs it relies upon..
The big selling point for isnipe that many don't realize is that it incorporates Litz' G7 BCs, making it much more accurate.
that is also another plus for bullet flight over ballistic, bullet fight uses litz numbers, where ballistic uses manufacture numbers. although the bullet flight program uses the litz numbers, it does not show you the actual value...this was done at the request of bryan. instead of showing the bc number it just displays "litz". i have the book so it is not of concern to me
