[QUOTE="med358-boise, post: 2594290, member: 123832"] A soultion you may wish to consider. You have 3 unknown variables - Is your chrono accurate? is the published BC accuracte, are your clicks accurate. Trying to figure all that out can be maddening. Consider the the following: Take your maxium expected shot distance, for example 800 yards Than actually shoot and record the clicks required to hit at 800, 600, 400, and 200. While the trajectory is of course a curve, click adjustments are reasonably linear over 200 yard increments. In other words, if you know what it actually took in clicks to hit at 800, 600, 400, and 200; you can extrapolate by simple division what it takes for the intermediate ranges. I ran this simulation for you and your worst case was being off by .6 MOA at 500 yards, that is 3 inches. If you are uncomfortable with factual data points every two hundred yards then use 150 yards and confirm 200, 350, 500, 650, and 800 and extrapolate between those. [/QUOTE]
