Re: Static BC?
IMHO, static BC is a mathematical equasion between weight and diameter (sectional density) and the form factor.
IMHO, dynamic BC is all things concidered and proven over firing tests. Velocity, bore quality, bullet stability, air density etc...will all come into play for the REAL WORLD BC.
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.
