[QUOTE="Dave King, post: 17765, member: 3"] Calibrated MilDots are 3.6 inches apart at 100 yards (3.44 MOA) If your 22-250 shoots dead-on at 100 yards at the crosshair and 4 inches high on the first MilDot there is a measurement problem I believe. You can run a ballistic chart for 3.44 MOA intervals and get the "distance" zero from that... best to actually shoot and see where they hit. You don't state environmentals so I used "standard" and a scope height of 1.75" 50 Nosler .238 BC Zero plus 3.6 high (first MilDot) = 3.6 high at 100 yards and .5 low at 350 yards Zero plus 7.2 high (second MilDot) = 7.2 high at 100 yards and .3 inches low at 475 yards Zero plus 10.6 high (third MilDot) = 10.8 high at 100 yards and 1.3 inches low at 575 yards. You can run the numbers using the JBM ballistic website same as me for the rest. [/QUOTE]
