[QUOTE="med358-boise, post: 2618792, member: 123832"] I am not sure what problem you are trying to solve? The purpose of mathematics is a decision, not a number. I would assume the decision you are trying to make is "What is the proper hold/set of clicks?" My understanding of BC calculations is that at the end of the day, they are extrapolations leading to a derived value. When I consider the preceding, inconjunction with: 1) Inside of 800 yards, trajectories are actually quite linear in 50-100 yard segments 2) Outside of 800 yards, minor mis-estimation of range will have a greater effect on drop errors that typical BC errors 3) Items 1 & 2, also aplly to wind. Given the above, it would seem that actual recording of POI at various distance given a specific zero would be a more effective decision process than all the calculations because there appears to be nothing in your approach that is going to lead to a more accurate calculation of BC which would result in better decisions. While I sincerely applaud the intellectual exercise, I don't see how the method described leads to better decisions than the method of relying on manufacturer's published data followed by actual field validation via shooting.
