[QUOTE="WildRose, post: 559298, member: 30902"] Yep and keep in mind that the chrono only gives you the actual speed at that point in flight. Listed BC's and actual BC's are two different things as well which is why you can build your drop chart according to the MV, and still not be correct at longer ranges. BC changes as velocity changes. Start with the MV as verified by the chrono, then verify drops at 3 different ranges such as 200, 400, 600, or 300, 600, 900 and adjust the BC to fit the actual data and then you can have a precision drop chart that will have you plus/minus just a few inches at any range.
