When punching info into the Ballistic program, all known parameters, the variables are mainly elevation and environmentals.
So, in the program to get an accurate drop prediction what changes..........its the effective BC of the bullet.
To say a BC of a bullet is x.xxx is most likely a reference to a standard.
Does it make a lot of difference , not likely , but it gives an understanding of what is happening.
Or , one could defend a position with walls made of words that include arrogance, BS, ridiculous, the obvious which probably is delivered with a huge eye roll.
