I see on the Berger web site that most if not all B.C.s for their projectiles have been changed. With these changes and other changes made by other manufacturers with the introduction of new bullets etc, my Nightforce Exbal program is rapidly getting out of date with regards to its bullet B.C. reference files. I only bought the latest copy 8 months ago and it is already way out of date! Anyone know how I can edit or update these files without having to purchase a new version of the program? I know I can do manual inputs but I would still like to keep the bullet B.C. reference file up to date.
