It is very difficult to come up with an accurate BC using the drop method at any range let alone just 200 - 600 yds. I show a drop difference of 1" from 200 to 600 using your numbers. That isn't much. How accurate are your click values? There are any number of errors we can throw in the pot doing our testing. What size groups did you shoot @ 200 and 600 and how accurately were they interpreted? Any up or down drafts? Parallax? Bryan uses much better equipment and methods and is a lot more experienced than any of us.
