Home Forums Reloading Reloading Software Changing BC values in QL and QT

I want to change the way BC is used for QL and QT using Bryan Litz's G7 values instead of the usual G1 value we are all used to working with.

Another problem is doing it for only a hand full of bullets used for long range since I do not have G7 values for all bullets. Anybody got a clue as to what I can do?
