Why do it at 100 yards?
Because if you shoot the bullet through your chrono at a 100 and do the same at 10 feet - you can calculatethe true BC of the bullet you are shooting at the velocity you are shooting it. BC is a function of velocity...
SL,
Do you know the formula for that and step by step procedures on how to calculate the BC? I have seen a lot of bullet makers inflate their BC, which would not be good when your trying to get accurate trajectory. PR Dead Centers come to mind on not being accurate BC. Anyway would like to know the formula and procedures on how to calculate. Good book on it? Thanks Chap
