[QUOTE="BryanLitz, post: 651633, member: 7848"] Jeff, When you're using the ballistic calibration, it forces you to calibrate MV from zero to a given range window (high transonic), then from there to the next observed drop point (low transonic) it calibrates drag. This method and the ranges are optimized to calibrate the solution in the context of Mach number. Beyond transonic range, the solution simply scales drop, but that's beyond the ranges most will encounter. If you really want to 'calibrate' BC/drag from muzzle to some range, you can do it manually, the old fashioned way. But the ballistic calibration interface was set up to force users to do what is usually the right thing. The original version allowed more flexibility but in testing it was found that users did many things wrong thru lack of understanding and ended up with worse solutions than they started with. So we enforced some policies to promote better use and results. -Bryan [/QUOTE]
