[QUOTE="Stumpm2, post: 636771, member: 5184"] From my understanding after talking with some Leica reps is that the 1600-B has 3 or 5 ballistics curves built into it (Probably something like a curve for a 68 grain 223, 168 grain 308 Win / common ammo curves). The user then selects what curve most closely matches the ballistics curve of your ammo and that is what is used and it is these curves that are corrected. There are three modes of operation with the actual straight line target yardage displayed first and then followed by the selected mode display. Mode 1 displays required elevation correction in inches needed for the yardage ranged and corrected for the measured temperature, barometric pressure, and angle. Mode 2 displays the required number of clicks required to hit the ranged target. User enters your scope click measurement (1/4 MOA, .1 mil, ect.). Mode 3 displays the corrected yardage to the target for a BDC dial. All of the corrections are based on the pre-loaded ballistics curves and I never did get a definitive answer on if this only works to 600 yards or has been updated to 1000 yards. [/QUOTE]
