What I cant understand is how is it possible to have a single shot kill in 1200m when you have 2/10 in a big target at 600m. I can understand the wind physics but i believe that at such distances the dispresion is much less than the described! Wikipedia says:
# Average horizontal spread at 1,000 meters: 10.3 in (0.984 MOA)
# Average vertical spread at 1,000 meters: 14 in (1.337 MOA)
meaning that it will have an 0,30 m dispresion is acceptable but not 5 or more meters! And thats at 1000m!!! At 600 m it should be even less!!!
I am saying again that i have disabled wind drifting so I should be dealing with such accuracies! there is no logic or predictability where the shot will go!
